all right so we finally have the a320 board I actually gave this to will for a small project he was taken care of back at his place this is the gigabyte a 320 M s2h we reviewed it in a dedicated video check it out right here but I do have an IR thermometer now so we're gonna be able to track the erm temps as we put this motherboard and the chip we're gonna put in it the 3900 X under load so we'll be able to see just how hot this thing gets when it tries to handle a 12th Corps and the way we can get it to handle 12 cores by flashing a new BIOS this is the f40 BIOS that gigabyte has listed on their website for this model board and you can see it says it's an update for a 3rd gen AMD Rison CPU full support and the only real downside to flash in this pass is that you're gonna lose Bristol Ridge support which is like the Athlon the a-series AP use like if you're rocking something that old I really don't think you're gonna be dabbling with a 3900 X anyway so you know you're trading off something that's likely not to be used in the first place if you have a CPU of this caliber granted I highly doubt anyone with a 1300 X is gonna want to pair it with an a320 board this is purely because I'm curious and that's it I also want to see how hot we can get the arms here I also don't care this board dies because it's super cheap so yeah let me be the guinea pig you guys don't don't copy this figure by its XIII 90 horas pro packs the necessities and more for next night gen Intel rig boasting a properly doubled 12+1 phase power solution stylish aesthetic with built-in backplate dual BIOS eight fan hubs the list goes on click the link below to learn more so if we're using Q flash utility to update the BIOS make sure you have updated BIOS to f/32 before f40 you can see f/32 is this one here that improves q-flash compatibility and improve USB device compatibility that's really it I don't see any other need to update here sometimes there's like a multi-step BIOS update process I'm not seeing that but worst case we'll play around it for sure we're gonna try to update to F 32 first and then see if it will take F 40 as is by the way if maybe we're asking for the model of this keyboard it's really cheap like 15 20 bucks I've linked in the description I only use it for when I'm troubleshooting like on they go like this so it's wireless it's easy to you know work with the USB 2 or 3 and prevents me from having just that many more cables to work with and I can walk around with it so that's why I use it alright we're gonna power it on there we go and we're gonna hop into the BIOS so we can flash it alright so we're in the Q flash window and we're going to update the BIOS click enter you can see we have two BIOS is listed want to update to F 32 first so we'll click that one alright and we're now on the F 32 BIOS we're going to update again to a 40 and again don't turn off power while this is updating and alright so we're in Windows I like booting into the OS when we're doing things like this just to make sure that everything is stable and we do need to update video drivers but I'm not going to do that until we swap CPU so let's go ahead and take out the 70 hundred X throw in the 3900 X and see if this PC even posts this is the 3900 X so every good bit that's down there I'll set up connect power supply again power that on let's see see if it works power cycling few times risin will do this someone mentioned that it's gonna train the memory I'm trying to tweak timings stuff to make it stable not sure if this board is gonna do that too many times but we'll definitely be patient with it and we'll see how long it's last alright we have a post folks and we can get the spinning circles yeah we got the spinning circles okay so we're in we're in probably gonna update a few drivers didn't even do that okay I didn't update drivers at all and we're in the operating system so this is the Fluke 62 max ir thermometer and you can see it's got a little trigger on the back whenever we hold the trigger down you can see that laser shows up on the keyboard over there and that is indicating where we're pointing that's where the temperature measurements are being taken so right now what 27.6 see updates to every tenth degree celsius and we're gonna point this at the V RMS throughout this video and see just how hot they get under both idle and load conditions alright so right now we are stressing the CPU FPU and cache in is 64 engineer this bottom choke here is the hottest I've been kind of playing around with it trying to see where its most toasty and right now we're around mid 70s I've seen it as high as 80 before but honestly these temps aren't bad for V arms like they're not terrible it could be better but this isn't absolutely horrid and you see if I move to the second lowest choke that temperature drops to I know it's hard to get both the camera and where I'm pointing in focused but temperatures drop to like 40 C third lowest choke 30 C nice and cool fourth lowest choke 30 C nice and cool - chokes up top or between 40 and 50 C for the most part and yeah the furthest right up top is about 50 52 C check this out so you can see our CPU temps there GP is not being stressed so ignore that but CPU at the diode is that lighter blue color up top 68 degrees Celsius right now that's what the stock 3,900 X cooler which is a pretty impressive granted burn an open-air test bench or a makeshift test bench musing the motherboard box but still these temperatures I expected to be a bit higher even at stock with the stock cooler but it looks like looks like the board's handling it well now let's check curious now let's see what our clock speeds are at stock and yeah we are pretty low let's go to statistics here I'm gonna swing the camera just a little more this way and I'm gonna drop the ISO so it's easy for you to see and I'm gonna scroll down to clocks and yeah so you can see our current frequencies they're anywhere between 3.4 and 3.7 gigahertz this is lower than spec I would expect all cores to boost to at least 4 we saw that with our other beefier boards so our a320 am is definitely gimping the 3900 X right now and this is one of the reasons why you don't want to pair a 400 or 500 ollar CPU with a $50 motherboard the CPU could definitely boost higher than 3.6 gigahertz the board is not allowing it to and the reason why it's not allowing it to is because the board knows that it cannot handle that kind of power delivery and so you're seeing power kind of alleviated here and back down as a result of frequency that of course requires less voltage and that means overall power delivery has been lowered so imma show you a few more spot tests with our IR thermometer here we're looking at the MOSFETs now you can see the laser where I'm pointing not the chokes but the MOSFETs themselves not too hot we move further down and temperatures actually lower so the MOSFETs higher up are the ones that are a bit hotter and by the way the chokes if you are just do the chokes are around 100 C I've been checking those out and those get to about a hundred but their chokes I mean these are not like it's not really a big deal that these are running this ha there's really nothing inside of them it's just some copper wire but the MOSFETs are I would say on the higher end in terms of temperatures but there's really there's nothing super alarming here honestly these temperatures aren't as hot as I thought they would be for a board of this caliber so again what exactly is happening here the CPU is not reaching t-junction it's not throttling itself okay it is actually just fine at 70 with the exception of a few spikes about 70 degrees Celsius under full load in is 64 full but it's not primary five look but still and yeah so it's not the CPU it's the board the board knows that it can't handle the power delivery requirements for this 12 core and it's rated boost frequencies it's within spec boost frequencies right this boosts up to four point what 4.6 gigahertz we're nowhere close to that granted we shouldn't expect to be at four point six all core that's not what max boost means but not even I mean we're not even at four gigahertz and we were at least at that with the I believe that be 450 we hit that and be 450 I've tested it you guys haven't seen the video yet but B 450 is just fine as well as X 470 and x-37b I expect to be just as good as X 470 assuming power delivery standards are in check you might have a few again X and P conflicts and things of that sort I'm not sure about PTO being included in those new BIOS revisions presenters support I'll check that out I'm sure others have already investigated it but for now I can certainly tell you I could have told you this before we ran this test that Avery 20 is not a recommended chipset for a 12 core or $500 105 or so watt TDP chip just the board can't handle it and again the relationship is because the board cannot handle the power delivery requirements it lowers frequency and when you lower frequency you can lower v core you can lower voltage to the CPU that of course lowers total power draw which keeps this board relatively within spec I wouldn't say 102 degrees Celsius is all that comfortable for VR em temps but at least I mean at least it works like if anything the one positive you can take from this is that you do have support like AMD's promise of platform support socket support through 2020 at this point looks to be a reality if you can get these chips to run on boards that emmitt that md didn't even say we're gonna be supported then that says a lot about the the socket it does aim for is an incredibly versatile socket and I'm really surprised that you might even included support present too with these a320 boards I'm assuming they expected you to use a much lower TDP chip so maybe like a 3,600 would have worked for this board I don't know for sure but the TDP certainly suggests that it would so with the exception of a few things you're forgoing like overclocking you probably could get this to work on a six core on a low TDP six core should say but for now yeah don't do this with an expensive Zen - chip thank you guys for watching if you want to leave a comment be sure to do so comment sections right below here and yes stay tuned for more cool experiments our Navi reviews are coming up very soon I have been I've been trying to get all that stuff compiled but we've got like six graphics cards we're you know we're doing the typical will graphics for benchmarks so that takes some time the good thing is you on the swap platforms it's just a card in and out install new drivers and good to go so anyway yeah I'll catch you next one thanks for watching this is science video and thanks for satisfying your morbid curiosity
