hey guys build Zoid here and today we're going to be taking a look at the V RMS of the gigabyte Oris Z 270 gaming seven motherboard and this is a sort of upper mid-range or lower high-end motherboard depending on how you look at the price point as it is priced at around two hundred and forty dollars if you want to go buy it so it is not cheap but it does pack a lot of features and of course we will see how good the V RMS are right here right now but before the vrm analysis this coverage is brought to you by cyber power PC and there's cyber XL gaming PC with an invertible motherboard tray layout and some rise in Brandon in the future maybe links in the description below for more information so starting off with the main V RMS on this motherboard we have the vcore located right over here and it is a rather old layout but it is in fact all vcore as was verified by with a digital multimeter and under this you find the IGP u v RM so i'll just write that down IG pu and that is three phases and the V Corps is eight over here you find the two minor memory control memory controller V RMS so this would be VCC IO and VCC sa both are controlled by these voltage two voltage controllers right here those are rich tech r t8 120 s and they are single phase voltage controllers very very basic controllers to be exact there now as budget basically you can't get less features on a voltage controller than one in this sort of eight pin package however that does not matter as both of these voltages are very very minor in terms of both power demands and importance on overclocking as they really only matter a huge amount if you are trying to push excessively high ram frequencies with very very tight timings and we are talking like for ddr4 4000 and CL 13 CL 12 CL 11 timings which is actually achievable on some very very expensive ddr4 kits what get once they are given enough voltage so for the average user the these VRMs basically do not matter at all for the you know extreme overclocker yes you you would want to see something maybe a little better than this however unfortunately we can't get well I can't get any details on the actual components making up to the this sort of group of VRMs or even how they're arranged which is why I haven't split them because the motherboards on the other side of the Atlantic and these inscriptions are impossible to read with how small they are so that that's sort of the situation with that vrm over there either way it does not matter a huge amount as they are very low power and there's no way you're burning those out even with very high VCC IO and VCC si voltages finally the last vrm that you really need to care about is the you know the RAM well yeah the RAM vrm right over here and that is another single-phase also controlled by an RT 8 120 from rich tech and again it's you know RAM doesn't pull a lot of power this one is a little bit more important as it will have much more direct impact on ram overclocking capabilities as you raise ram voltage however even a single-phase is plenty for ram overclocking in most scenarios only at the very very top end you know you're gonna start seeing issues if you don't have a well you might not even start seeing issues you you would see benefits from having say a two-phase design or something more complicated than just a simple one phase like we have here so now that we know all the nee RMS let's take a more in-depth look at what they're actually made up of the V Corps and the IEEE GPU V RMS are both controlled by the inter cell ninety five thousand 866 which is a really long name for a voltage controller either way this voltage controller is a 4 + 3 phase design and as such it becomes rather old that the V Corps here has one two three four five six seven eight inductors the IGP you've erm obviously doesn't have any issues as it only has a one two three so that three phase setup right there trans is you know exactly proportional to how many phases the inter-cell voltage controller is actually able to put out for that section of the V R M so the V Corps has to use some kind of doubling scheme or it has to be cramming more inductors per phase than there are phases luckily gigabyte chose to do the right thing and we do actually have eight phases however I am not sure how exactly they are all controlled as the motherboard is on the other side of the Atlantic for me and we can't get data sheets for these ICS in the v RM right here and also I'm not sure if there should be more of them because there's only four and then there's no drivers for the actual AI GPU v RM so this V R M is kind of a mystery to me is with the fact that I can't you know get my hands on and measure everything manually so working long distance this is an eight phase-- v RM as far as I can tell but it I am not sure how exactly those eight phases are controlled so in terms of actual power capabilities it is equal to a eight phase-- v RM in terms of say voltage regulation it could be slightly worse than a well it's definitely worse than a true eight phase but it won't necessarily be on par with say a four phase depending on if these are actual doublers or if gigabyte is just choosing to put two phases onto one control signal which would essentially mean that it has the voltage regulation quality of a four phase but both are actually completely fine as kb lake is an extremely low power architecture and as well as skylight and both of these are compatible with the motherboard because it does use the LGA 1151 socket so pretty much regardless of what you put in this motherboard it's not gonna be very it's not going to be negatively affected by gigabytes you know interesting a face he's uh design decisions however well unless you start taking the system on lnto and even on ln2 you should actually be just fine I think unless you're like - aiming to break World Records this vrm really shouldn't be holding you back especially not in terms of power capabilities because the MOSFETs in here are Serie well s IRA and that is actually how it's done in the datasheet 18 dps for the high side which are not super high-end MOSFETs but they are completely adequate for the application here especially with how many phases gigabyte opted for and this one down here is a serie and yep that that same thing twelve DP so both of these MOSFETs are made by vishay and with AVR em you know predicted operating setup of 125 degrees centigrade 500 kilohertz switching frequency which no motherboard as far as I'm concerned has ever shipped at so 500 kilohertz is sort of a safety feature from my side for BRM ratings because that 500 kilohertz makes me slightly underestimate the power capabilities same goes for that 125 degree figure as this vrm is an eight phase-- providing very little current with a massive aluminum heatsink on top of it this vrm really shouldn't be getting particularly hot unless you have abysmal case airflow so again 125 degrees 500 kilohertz both sort of overkill ratings my voltage rating is going to be 1.5 volts which is slightly above what you want to be running kb lake or skylake app for 24/7 usage as both are recommended to run about 1.4 1.45 depending on who you ask so with these expected operating settings this 8 phase vrm right here is should be capable of delivering 256 amps straight to the CPU so no issues absolutely no issues as kb lake and skylake both have a sub 100 watt TDP and even when overclocked they will not be pulling much over 200 watts on to the 8 pin so that's before conversion loss on the lis RM so really this 256 m figure is a very nice margin of overkill from gigabyte you'd probably have to put the system on ln2 and do something force the vrm to actually hit 125 degrees that's the other issue here and then you might be able to actually you know damage this vrm otherwise yeah this is perfectly fine without gigabyte designed it so taking those same running parameters for the eye GPU which you know I have no idea how to rate an eye GPU because I doubt anybody who who has this motherboard is gonna use the eye GPU like I really really hope you're not using the eye GPU if you have this motherboard for anything more than like say checking that your main GPU works or or something like that you really shouldn't be using a GPU on a two hundred and forty four hundred and two hundred and forty dollar motherboard you really should have a discrete GPU and if you have a discrete GPU well this vrm is completely irrelevant to you but on the off chance that you don't have a discrete GPU well I have good news for you these MOSFETs are exactly the same as the ones in the V Corps so you know again Serie 18 DPS for the high side serie 12 DPS for the low side and a combined current throughput of 96 amps across those three phases again using those same running parameters so moving on onto the ramp erm this is slightly different in terms of mosfet selection this runs only serie 12 so 0 12 high side 0 12 low sides and there's two low side effects inside the vrm which is mostly an efficiency feature as the low-side can significantly out power the high side either way this vrm right here delivers a maximum of fifty six amps again that same running spec of 125 degrees 500 kilohertz and 1.5 volts within the view with the RAM vrm that 125 degrees figure might be a little bit more achievable but 56 amps is not achievable with ddr4 memory modules just no way ddr4 runs again extremely low power we are talking say about 4 watts per stick even when overclocked they will not be pulling a significant amount of power even if completely maxed out and by completely maxed out I mean 2 volts in you know RAM voltage and 4000 megahertz frequency CL 12 se which is again achievable on very high-end kits you will not be getting anywhere near to that 56 m 6 m figure so no complaints about that vrm from me either and overall gigabyte has done done well on this vrm I'd love to know how those eight phases are actually controlled and I might have a slight suspicion that maybe these two drivers aren't actually part of the V curve erm but the problem is there's also two drivers sitting in the IGP you've erm and you've gotta start questioning where are the I GPU drivers because two of them can't drive three-phase is there's no way that's working so yeah I'd really love to know the specifics of how the vrm is exactly controlled but as a right now capable current throughput wise no complaints on any of the major V RMS on the motherboard voltage regulation wise it's always nice to see a true eight phase but then again true eight phases are extraordinarily expensive and very very rare as a side effect of that so no real complaints that gigabyte hasn't opted for one here especially since it's probably completely unnecessary with the target audience for this motherboard which is gamers who wouldn't really benefit from a true eight phase design anyway one last thing to note about this motherboard is you do have voltage read points buried right under the sort of in that area there are voltage reach points for all the voltages on this motherboard so v core Ram voltage VCC io v CCSA and every other voltage you could possibly need when overclocking a KB lake or skylake CPU inside it put into this motherboard and you do also get onboard buttons so it does have some of the overclocking goodies not necessarily all of them but yeah the this motherboard wouldn't let you down unless unless you probably went on ln2 I think even for dry ice you would be fine using this motherboard so that wraps this up there is a full review of this motherboard up on the gamers nexus website consider donating to the gamers Nexus patreon to support what we do here and
