Gigabyte X570 Master VRM & PCB Analysis | Efficiency Estimations

2019-05-27
hey guys build Zoid here from actually hardcore overclocking and today we're gonna be taking a look at the gigabyte X 570 master motherboard so this is obviously a you know a.m. for motherboard based on the X of X 570 chipset meant for the new Rison 3000 series CPUs and I am recording this video so far in advance of the actual CPU launch that I know basically nothing about the CPUs other than there's going to be a 16 core and a 12 core and an 8 core so I know how many cores there's gonna be I don't know when they're launching how much they're gonna cost how they're gonna clock how much power they're gonna pull basically I don't really have any information that would really help me with sort of gauging how overkill this motherboard in front of us is though it should be pretty damn over killed before that this video is brought to you by drop and their HD 6 xx headphones the 6 xx headphones offer high-quality audio output with wide device compatibility mouth drops 6 xx also includes a 6 foot cable with 3.5 millimeter plug alongside a quarter inch adapter for those who might want to plug into an app the 6x axe focuses its energy into balancing the sound leaning toward warmer and base your audio they're also easy to disassemble and replace individual parts making these headphones trivial to maintain for long-term use learn more at the link below this is not gigabyte highest end board there's also the X 570 extreme but this has a lot of what made like this keeps a lot of what makes the extreme so very extreme so then let's get right into it starting off with the most interesting section of gigabytes new x5 70 series motherboards at least in my opinion I think a lot of people might be like builds like the v RM really isn't that interesting but damn it this is my video so I say the RM is most interesting section so first of all we have a V core this right here is our V core erm next to that we of course have the SOC v RM so that power is the system-on-a-chip portion of a normal rise in CPU I would assume that for the upcoming rise in 3000 series this is going to be powering the iodine also if you're running an APU this does power the eye GPU though this motherboard as far as I can tell does not have any display outputs so you know the fact that this can power the eye GPU is kind of irrelevant in this case now what makes this v core VR the this VRM configuration really really special like right now you might be looking at this and be like oh there's not that much this is not that different from other boards we've seen it before but this has one two three four five six seven eight nine ten eleven twelve phases and no doublers in the v core section and then the SOC is just another two phases so this is not you know these aren't fake these these this is actually twelve this is an actual 12 plus two-phase VRM and the reason for that is is like the X 570 extreme the master uses this chip right here which is an Infineon X do this this photos so high-res that you can actually read it right off of the chip but that is an XD PE 1 3 2 g 5 C so part number worse than ever before ir35 2:01 kind of rolls off the tongue kind of rolls off the tongue after you've said it often enough this this never does this is just too damn long but this right here is a 16 phase controller from Infineon Infineon is the company that actually owns international rectifier so you know you can kind of consider them interchangeable now this thing is this thing exists primarily for powering like insane server setups and you know like non-consumer pc non-consumer design silicon designs where you have chips that are absolutely massive and can pull easily as much as a thousand amps like that's actually the use case for this that that's like the design that's the use case for this controller right here is just like in Finian's marketing is like this is the first proper 1,000 amp voltage regulator that like we've made and it's really meant for servers but hey that never said like that that's never stopped consumer motherboard vendors from you know shoving super-high-end voltage regulator components onto onto motherboards that are never going to power anything with quite as many cores or as much power consumption as a server platform but so still like this is not a new thing that we have like high-end server grade parts on a consumer board but it is a new thing that we have an actual 16 phase like this was previously not possible there's never been a controller that went all the way up to 16 phases there's been like one or two controller well there's more recently there's the mp-28 88 which goes up to 10 phases but in the past there's also been some controllers like I think UPI semiconductor had a 12 phase at one point in time but that quickly became like nobody really used it that much but 16 phases this this is a first like this is the first time there's ever been a controller that goes up to this many phases so problems 2 gigabyte for just going right for it what as soon as it arrived it's like oh yeah we we like having a lot of phases we would prefer not having to use doublers for them and the reason why you'd prefer not to use doublers to get lots and lots of phases is that while doublers have their upsides you know you can get better vrm efficiency you can get reduced output ripple because you effectively have all your phases interleaved the the downsides are having a bunch of doublers is that you put a bit of delay on to your PWM signals and I can potentially make that basically makes it more difficult to optimize the transient response of the vrm which you know for CPU is not really a huge it like not really a huge priority because unlike GPUs CPUs don't really power cycle anywhere near as hard but still you know it can make the different like there there's ways to design around it but ultimately hey if you can buy a 16 phase controller you can have all the benefits of having 12 interleaved phases and none of the downsides of doing it with you know six six phases and a set of doublers so yeah awesome awesome controller to see right here and the X 570 extreme also uses it and actually uses it to further capability of the the 14 plus 2 configuration the plus 2 of course here is for the SOC vrm now the actual vrm itself the the well core and SOC vrm the the power stages used our international rectifier 35:56 is which actually puts this x5 70 master well above say the z3 90 master in terms of erm power delivery capability which is just kind of a interesting thing in my opinion because well not well above well it's 25% I'd consider that well above so the 35:56 is a 50 amp power stage whereas what you'd find on like the z3 90 master is a 40 amp power stage they both still have 12 phases it's just that these phases are quite a bit more substantial than what you would find on the master so what that means for the via vcore vrm efficiency here keep in mind I have no idea how much power a say overclocked 16 core rise in 3000 series CPU is gonna pull just absolutely no idea I've not been given that I've not been given any reliable information on that but we can still talk about how you know the the efficiency capability like the vrm power delivery capabilities and just kind of once the CPUs come out we can go okay well they pull this much and then you can fit well with this motherboard the this motherboards efficiency well power delivery kit well efficiency and power delivery like the thing is if you're vrm is not very efficient that just means you need to put a bigger heatsink on it now at some point your heat sinks just never gonna be big enough so you need a very efficient vrm to not to be able to handle a lot of power without like resorting to water cooling the vrm in order to keep it from overheating so anyway the RM efficiency we're gonna be looking at 1.2 volts output because that's the voltage that the datasheet of these is spectin and it's just convenient for me to use especially since I don't know if we're gonna be running these 16 like I don't know if we're gonna be running the rise in 3000 series chips on 1.5 volts or one point one volts right like it's 7 nanometer we could be looking at very little voltage we could also be looking at a ton of voltage like who knows who knows how am d-- decided to to go with the chip design the 400 kilohertz switching frequency because again that's where the datasheet is specular also gigabyte tends to actually like their gigabytes recent motherboards that use the various ir35 50 series power stages are like 3553 35:56 is they all tend to default to 400 kilohertz switching frequency so I'm assuming they're not gonna be changing that for this one so 400 kilohertz switching frequency and 5 volts Drive and the the reason why I'm pointing out the 5 volts Drive voltage is because the datasheet for these actually has all of its efficiency curves done at 7 volts Drive which is not great for the reliability of these power stages like you can run them on 7 volts they're just not gonna last as long so essentially they're over voltage for the purposes of the efficiency curves in the datasheet to make them look a bit better there's some GPUs that actually like run these on like 6 volts but gigabyte for their motherboards they always go with 5 volts so 5 volts drive for these ultimately it doesn't really make that much of a difference to the overall efficiency it's just a couple percent anyway so 100 amps output at 1.2 volts so about 120 amp 120 watts going into the CPU you're gonna be looking at about 13 watts of heat dissipation so yeah like the RM shouldn't even need a heatsink at that point plenty of surface area lots of phases you know you're looking at a little over a watt per power stage in the V R M so you shouldn't even need a heatsink at that point as long as you have even just moderate airflow over the vrm section now going up to 150 amps 1.2 volts output you're gonna be looking at about 17 watts of heat coming off of the power stages again so at this point you know a heatsink might be advisable but it doesn't need to be very substantial especially considering that this is a 12 phase actually you'd probably be able to get away with no heatsink depending again on your airflow situation and going up to 200 amps output we're gonna be looking at about 22 watts of heat coming off of the power stages and that basically well at this point you you do want to have a heatsink okay it doesn't need to be the the world's biggest heatsink ever but you do want to have a heatsink airflow is kind of optional still and especially considering that like with the heat sink that gigabyte house on the Z's Oris Master if they go with like the same style of heatsink for this board like yeah this will be no problem and will be no problem for this board to handle now going up to 200 and not 250 at this point like 200 amps I think is kind of unlikely for a rise in 16 like even for the 16 Cory I think this is like a worst-case scenario situation that you would hit 200 amps on ambient cooling because the thing is is like it's one thing to say oh yeah you can totally shove that much power into the CPU it's another thing when you need to actually cool that much power and generally well I don't know how the thermal density is gonna work out the the cores are gonna be kind of offset from Center so that might affect how efficient various water blocks are so yeah not really sure how this this is gonna work out I kinda think this might be the limit for a CPU in this package sighs then again if we think back to the effect well no the FX series CPUs were right around sort of the 1.5 volts 200 amps like if you had an FX 8 core that that's roughly what you'd be looking at so yeah this is a huge upgrade over like the best am3+ motherboard ever made this vrm right here like it doesn't even compare so yeah I'm just realizing how like the am3+ motherboards were so sketchy to rut like some of them are so sketchy to run an eight-core on and then it's like oh here it's like you know just 22 watts yeah so you know like this might be pretty much the limit if if that's even possible but going up past that you know just for the sake of what the motherboard can do 300 amps output you'd be looking at about 36 watts of heat a good heatsink design a good heatsink and some air flow should have no problem handling that going up even further than that 400 amps at this point we're kind of going outside of where you'd want to run this VR I'm like this this one's really designed for sort of the 200 amps that that's kind of the sweet spot for this vrm is 150 to 200 amps and then going up past that if we go to 400 amps output you're gonna be looking at about 59 watts of heat which is like that that's a lot you can definitely do you know we RM he thinks I can handle that especially considering that this is a twelve face so it's not all crammed into just a couple power stages but uh it is still like that that's not you know an ignoring amount of heat luckily I think four hundred amps is probably only achievable if you're on a line to cooling and even there it might not be possible who knows like again I have no details on the CPUs but if you know like on lnto the thing is you're not gonna be running that load for a very long time so it doesn't actually matter that you know as long as the arm doesn't overheat before you finish the benchmark you're fine so that there is like that's concerning for like long-term usage a lot long-term loads not necessarily for you know even extreme overclocking and going up to five hundred amps at this point we're very much you know ninety three watts of heat output the the thing about like a lot of the power stages when they're spec for 50 amps well they're the the way that spec works is considering a single power stage which is okay like basically surrounded by a great big square of just empty copper and it's like yeah we can totally push 50 amps through that one power stage under these testing conditions it doesn't really consider what happens when you put you know 12 of the 50 amp power stages next to each other and it's like well now we have 93 watts of heat instead of just because this is a little over this is a little over like eight watts per power stage so if you have one of them that's not really a big deal if you have 12 well actually that's is it a little it's slightly under eight watts per power stage for this so you know if you have one of them not really a big deal if you have 12 of them you get you got a problem it's 93 watts you actually like a lot of airflow substantial heatsink that this is not something you just kind of you know like this is not something you would actually want to sustain the holder sustained sustained output out of this vrm unless you have something like a delta fan cooling it still a very powerful vrm on this motherboard i mean you know it is stronger than what you get on those e39 urs master it's it's like that doesn't in like it does get better than this but I'd say better than this is kind of unnecessary so yeah like the extreme is extreme like the extreme is extreme for a reason and it's even better than this this right here but uh this already is more than enough especially within sort of the SE nor can't draw levels even up to 300 amps I mean that's still if you have a good heatsink design you can totally handle 36 watts spread across 12 phases that's not a problem so yeah you know brought like XIII the this thing is just kind of carrying on the legacy of the XIII 90 master where it's like we've got a 12 phase we got decent we've got good power stages got a solid vrm and they've actually upgraded the power stages on this thing so yeah you know it just gets better then for the soc BRM we have more 50 amp power stages since this doesn't have a display output is like the end the AP UI GPU doesn't really pull that much power it's just like well the this exists don't worry about it the main concern here is the v court also you know gigabyte is going with the dual 8 pin power connectors for CPU power I have like I've heard some things about the 16 core I have serious doubts that you would ever actually exceed the power delivery capabilities of the single ap you can easily like I've been pushing 300 watts into ITX as III 90mph okay actually I think I've been pushing over 300 watts into Z 390 ITX ports like you're nowhere near maxing out this this ape and power connector until like the 8 pin can do at least 400 watts if if you have a halfway decent power supply and it will get warm okay it's not like it's gonna be ice-cold but it will still be within the tolerances of all of the the materials used to build it so yeah I don't really think the 16 core has a chance of overloading the the single 8 pin but hey you know maybe if you're on if you're on liquid nitrogen who knows maybe maybe the 16 core scales - like 2 volts at - under 96 degrees pulls a thousand watts there's already a different 16 core from you know Intel that does that so it could be possible that the this ends up doing something similar and in that case the extra 8 pin would be kind of handy wouldn't it but yeah for ambient the the single pipe and is more than enough so yeah that's the that's the power delivery on the board for the CPU moving on for the memory power we just have a like you know it's nothing nothing impressive but it's nothing bad so we've got the standard gigabyte single-phase we've got our our t8 120 voltage controller over here we've got our 4 C 10 n high side MOSFET then another 4 C 10 and as a low side and another 4 C 10 and as another low side this is gigabytes go to single-phase memory of erm for like the last several years I want to say that they've just been running this memory of erm I know it works fine it's perfectly acceptable I've never had any oh well yeah I've never had any sort of memory overclocking issues on gigabyte motherboards related to the actual vrm most most of the time when you're looking at ddr4 overclocking because ddr4 really doesn't pull that much power the the main concern with ddr4 overclocking is everything that happens between the memory slots and the CPU and arguably the output filtering of the vrm but uh and that looks like a pretty standard gigabyte affair these capacitors right here I'm wondering if that might be just because this isn't technically this board is a engineering sample the retail boards are always rev 1.0 so this is an engineering sample board so it might be just like that they're not there for testing or something I'm not sure normally these would I would assume these end up being populated because it's pretty standard to have bulk capacitance between the memory controller and the DIMM slots that's just kind of a standard thing for a lot of higher-end motherboards about AB so you can mess around with like the output filtering but most of it comes down to what do you do with all of the traces running in this area and in that aspect all of gigabytes x5 17 motherboards are actually going to be using a daisy-chain memory layout which favors a to dim which generally favors to dim configure 8 to dim configurations because there's basically two layouts that you can look to have on a motherboard there's t topology where you have equal lengths to both DIMM slots on each channel so like this is channel and then you have the next channel so teach apology looks something like that daisy-chain just looks like bam it's much easier to layout it's much simpler to layout and daisy-chain actually like the daisy chains issue is that you end up with a timing difference between this dim and that dim there's a timing difference between the two but if you're only using you know one one dim slaw on each channel so like a two by eight configuration or a two by sixteen configuration daisy chain works really really well assuming the motherboards BIOS is also tuned for it cuz you know if if you screw up your memory training setup then it kinda doesn't matter what layout you have because it's just like well the board's gonna be set up wrong but since with with AMD CPUs there's the a GSA which is much like as I understand it the motherboard vendors don't have anywhere near as much power to mess with the memory training algorithms on AMD CPUs as they have on Intel so I would assume like and the thing is on X 470 all of the like MSI uses daisy-chain asus uses daisy chain asrock uses daisy chain so I'm assuming basically what's been happening is that the asrock asus and msi feed back to AMD about hey how to tune the memory training algorithm has been tune it for daisy chain and at this point it's just like well it works best with daisy chain so everybody's going to daisy chain so i think ultimately the board should be you know if nothing else pretty consistent and I'm kind of happy that gigabytes going to daisy chain because in the past they've used it apology and the thing is yeah it really doesn't work it does cap your maximum frequency when running to DIMM slots over running when running to dims over for demons so it should work better for you know the the more casual memory setups instead of the insane like four by eights or four by sixteen setups you can still make daisy chain work in a you know four by four by eight or a four by sixteen setup it's just a bit more work but considering that daisy chain has been standard 4 X 4 7 X 4 70 for basically three of the four big motherboard vendors I'd assume that it's already AM d already has it pretty well fine-tuned even for Fortnum configurations so anyway that's some memory power over here and then we've got a postcode which is a nice feature to have if you're doing any you know for troubleshooting any kind of boot issues much more useful than just having some troubleshooting LEDs though you do have those as well so this is like a quick indicator of what's wrong this is the look it up in the manual indicator and you might actually get something that's more specific than just oh there's something wrong with the CPU that this can tell you things like oh you try two failed memory training or you failed your GPUs not the motherboard can't see the GPU you know those kinds of errors the post code much more helpful than just some some LEDs like that so that's a nice feature to have also have voltage read points up here you know for people like me who aren't happy with just having with just having with your software readouts because they're not always that accurate these are just solder bumps so no nice header but the same like gigabyte is ultimately gearing most of it like their motherboards towards gamers not extreme overclockers so I totally get why there's not like connectors on that for multimeter probes but yeah it's you know at least it's there but much simpler than then having to like well actually for me if I'm gonna be soldiering connectors to the motherboard I might might as well just solder them directly behind the CPU socket or something so at that point it kinda doesn't matter but if you don't want to modify the motherboard this is a lot more convenient than trying to stab the back of the board with a multimeter that's generally quite hard to do especially if you have it on test bench actually it pretty much impossible if you have it on test bench we've got a power button we got a reset button in the correct location they're also located on the back but if you remember some of my past videos with gigabyte boards I've actually complained that like why would I want the power button on the rear i/o if I'm gonna be using the board on the non test bench so yeah now we have them in the right location we've got a we have dual BIOS so a BIOS selector switch and a BIOS dual BIOS mode enabled disabled switch I'm not sure which ones which but basically you know gigabytes dual BIOS can be a little bit less than cooperative when you're doing your when you're doing memory overclocking and just failing to boot over and over and over again it can sometimes get a bit trigger-happy and go from the main BIOS to the backup BIOS when you don't need it so here you can you can force it to stay on one BIOS for your entire overclocking session which in my opinion like that that's really convenient because the thing is if your BIOS shit like if it goes from the main BIOS to the backup while the BIOS profiles are actually tied to the BIOS chip that you're using so if you save a bunch of profiles on the main BIOS and then it switches to the backup your you don't have any of your profiles so you'd need to switch it back over and on a lot of other words that's like a button to like on motherboards where you don't have the switches that's just not possible to do can be easily so this is a really nice feature to have on gigabyte motherboards it's standard for all of their high-end stuff so no surprise that the the x5 70 master has it but still nice that it's there we've got our 24 pin some fan headers debug LEDs going down and they've kind of ruined the color coding on the why is that freaking out they've kind of ruined the color coding on the front i/o like normally it would be really colorful and now it's just grayscale which is a like I preferred it when it's colorful I could get that it might look nicer and it's somebody's PC but it's just like it was easier to to work with when it was fully color coded in my opinion I'm pretty much covers all of the overclock well no we do have a socketed and so your here's your BIOS chips your backup BIOS is soldered onto the board the main BIOS is a socketed so if you somehow managed to brick both the backup and the main BIOS you can potentially just ask gigabyte to send you a back a new main BIOS chip and you'll be back up and running so yeah this is also a nice convenience feature and other features we have on the motherboard there's going to be Wi-Fi 6 add-in card right here this is a 2.5 gig LAN controller from real Tech if you're like me and you think real tech sucks there's also a one gig Intel on down here so you're covered 2.5 g I'm like I haven't used a real tech network controller in ages and ages and ages so I don't know how bad it is but back when I you had a real tech faced motherboard it was not a good experience so let's put it that way but that is a 2.5 g and you still have your Intel M so you know yeah you have options so that pretty much covers it for the O now that covers it for this board I mean the only other thing worth mentioning is that the x5 70 chip says you can kind of see is a loss of silicon it gets kind of halt and if you're doing basically from what I've been told if you're running em Dell to SSDs in like a raid zero setup this thing needs active cooling because it just gets really really hot when doing that otherwise it's actually just fine but raid em dealt to setups are a bit like they just get hot on that so it's one of the issues that's actually been like that's been one of the main issues with the x5 70 platform is just like getting that chipsets heat output under control and eventually that thing that didn't work like they never managed to solve the issue of it running really hot so now it's just like boards have fans on that but the fan can take care of it and you know ideally like I'm not sure about this but I'd hope that the board has a hybrid fan mode so the fan only kicks in when it's actually necessary instead of just all the time no even if it's spinning all the time as long as it's not like a super high rpm it should be relatively ok so yeah that's it for the x5 70 master from gigabyte the Auris x5 x5 70 or ass master there finally got the name I'm still like yeah it's always gonna be gigabyte for me always it's not a significantly better magnet name but I do prefer I I'm used to it at least so it's the x5 70 master it definitely looks like a really like I think this is a this looks like a really solid motherboard to me quite possibly like it does everything like that it kind of does everything the extreme you know it's a kind of extreme the extreme adds at the 10 gig line slightly big well actually not slightly better VR I'm like it's on a whole new level of erm but it's just like this is already so good that I don't really see like I wouldn't you know push you towards the extreme just because it's like oh the arms like way better it is but it's just you probably won't need it so yeah but this is definitely a really really solid x57 you know solid looking x5 70 motherboard kind of like looking at the master and the extreme it kind of feels for me like gigabyte basically what made a checklist of things I've complained about in the past when looking at their motherboards and then they just went and made sure that there's nothing on that like nothing has been left unaddressed it's like builds Lloyd's complained about this in the past it will not be on our motherboards anymore because we got the dual BIOS we like we got everything solid of erm there's just nothing really here for me to complain about so yeah that's it for the video thank you for watching if you'd like to support gamers Nexus directly there's stored gamers Nexus dot I mean there's the gamers Nexus patreon if you'd like to buy some gamers Nexus merch there's store dot gamers Nexus not net and if you'd
