Vega 64: VR SOC / VR Mem temps >100C

Sumanji · 19 Jun 2018 at 06:47

Hi All,

Put together my new machine on the weekend, and I'm a little concerned by the temps reported in GPU-Z...

While playing PUBG, VR SOC and VR Mem both going up to ~100C. GPU core is 78C and HBM is 85C ish (all numbers are max reported temps under load). Card is an Asus ROG Strix Vega 64.

The fan is also getting pretty loud (2400rpm / 60%), which I think might be caused by the VRM temps?

Would be great if you guys could share load temps so I can compare please!

Cheers,

Those are PCB temperatures so Can add 5c easy.
Remember when People said Vega can set Yours house on fire ??
I would not get one without WC

My 56 & 64 bios and heavy clocks never seemed to get that warm.
Maybe some cards dont have good contact with the cooler.

The Stryx isn't the best cooler for Vega, I'd only go with Sapphire personally (and possibly Powercolor).

Try taking the side panel off of your case, might drop temps a bit.

I dont think that sound card under gpu helps

I'm sure it definitely will, but that sort of defeats the point of having a case right...

Roughly what temps do you get on your 64?

Yeah I wanted the Sapphire Pulse 56, but no stock

It will tell you if the problem is airflow or a bad card.

Urgh, the Asus card temps are a complete joke versus the Powercolor... wonder if I should exchange it?

That's why it's called "torture loop", because it puts an incredible load onto the GPU raising it to crazy temps it would never see in the real world. You wouldn't wanna leave it running that long with water cooling either.

JediFragger · 19 Jun 2018 at 15:20

Didn't you do any research beforehand? Well known that the Stryx cooler just can't handle Vega very well.

1 of those could have a much higher fan speed set however based of the pics alone i would. my reference 56 is also heavily overclocked like sideways14 and never gets that warm.

With water loop you would not see more tah 60-70 ever

Cyber-Mav · 19 Jun 2018 at 19:49

those temps are normal. you have to take into account you have a card thats inefficient compared to the competition, so it will run hotter.

Davedree · 19 Jun 2018 at 20:56

Like I said in this post back here, you just answered with stock clocks and voltages.
But what are they? 1.15v at a throttling 1440-1480mhz ?

If you could confirm the voltage and clock speeds you are seeing then we can see if the card is overvolting for the sake of it. By experimenting with undervolting it may be that your card will respond to lower voltages and resultantly less heat being emitted.
Say like 0.925v for a held 1450mhz, or 1.0v for a held 1550mhz etc.

Apologies buddy, please see below:

Getting differing readings from GPU-Z and the Strix tool.

Strix is reporting 1.2V which seems insanely high for stock?! Whereas GPU-Z shows between 1.00-1.05V

I guess I should try manually setting the "stock" Vega 64 voltages and speeds and seeing if that makes a difference?

Cheers,

Su

Davedree · 20 Jun 2018 at 00:18

Thanks for the pic, as far as I've been able to see the Asus bios configures v64 for 1630 at 1.200v and with vdroop it hovers around 1.15-1.16v. That gpu-z is it a log of a game in full screen mode?
Something doesn't look right, the core clock is only in the 1200's and the hbm clock is only hitting 800mhz and the voltage is holding 1.00v. so maybe a profile isn't configuring the p-states properly. If it was me I'd use overdrive tool or amd-wattman.

Sumanji · 20 Jun 2018 at 00:31

Thanks for looking Dave.

I added the 2nd pic with AMD Wattman and HWMonitor also. Yes, I just loaded up PUBG (which puts 99% GPU load at the title screen). But maybe it's not boosting all the way up to 1600MHz because it doesn't need to? I have AMD frame rate limited to 100fps, so that could be why.

Apparently the Asus GPU Tweak software is a pile of garbage, so I am going to uninstall and use AMD Wattman.

Davedree · 20 Jun 2018 at 00:46

Yeah that's probably explains the clocks then as it was in menu, as long as in realtime gaming you are seeing it hold around 1460mhz and 945 on the hbm then it should be working properly. Still take a note of the voltage it uses when it is underload etc. I'd say if you tweak it then you should be able to get those vrm temps down by 10-15c. And so lowering the heat on the PCB die area.

Sumanji · 20 Jun 2018 at 01:52

Huh weird, I think it may not have been the frame rate cap after all. Played around with Wattman:

1.10V 1537MHz +50% power limit:

1.05V 1537MHz +10% power limit:

Something feels wrong and I'm not sure I can fix it by tweaking in Wattman?

Considering just returning this and getting the Sapphire Pulse Vega 56 - ComputerBase.de review shows it about the same noise & temp levels as a GTX1060 under load.

Happy to bite a restocking fee just to avoid all this faff...

Cheers,

Su
