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

[Panos]

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

True that, but if he wants to watercool the card later on, is the only option since EK makes a Vega Strix block.

There are no reference PCB Vega 64s left in whole Europe atm at the price of the Strix.
I am searching for a week now across many countries.

There are couple MSI in Germany but their price is exuberant. Strix + waterblock from OCUK cost much less. And can sell the headphones to pay for the block.

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.

5 posts above yours is a picture showing much lower temps with the same card...

You can have a card pulling 1000W and still run cool if the cooling is designed properly.

He didn't mention WC though? I know you're after WC a Vega if memory serves? I'd personally go with the Sapphire if they were my £££, those cards are proper thicc and look cool as hell

Unfortunately the ones on sale are not reference PCB, so no waterblock for them.

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,

Su

Use the iChill software in your raedon settings. It'll downclock the GPU watts without affecting performance.

Have you undervolted the card?

Are you using stock case fans?

If so you should buy a triple pack of AF (Airflow) fans and replace the stock case fans. The new fans will shift a lot more air and keep the case cooler.

...as long as in realtime gaming you are seeing it hold around 1460mhz and 945 on the hbm then it should be working properly.

Did some further playing around last night... at stock volts/clocks, the card is NOT holding "full" speeds under load. It hovers between 1200-1260MHz on the core, but 945MHz on the HBM.

In Wattman, I played around to give it 1.050V on the core, 1.000V on the HBM and max core clock of 1537MHz.

At stock power limit, it would not go past 1200MHz on the core:



Raising the power limit to +30% it initially stayed at ~1400MHz for a while, but then the temperature got crazy and the card started throttling... (109C on the VRM!!):



I guess I could try giving it even fewer volts on the core (<1.000V?), but really it feels like I shouldn't have to be fannying around so much to get the card to run properly at stock speeds...

You can have a card pulling 1000W and still run cool if the cooling is designed properly.

Exactly... I think this Asus cooler is total pants.

I'd personally go with the Sapphire if they were my £££

Sapphire is always my first choice... if you can find me one in stock over here, I'll buy you a cookie

The Sapphire Pulse Vega 56 is in stock for ~$500 so I am just considering pulling the trigger on that and getting rid of the Asus tbh...

Use the iChill software in your raedon settings. It'll downclock the GPU watts without affecting performance.

Have you undervolted the card?

Chill is a good shout - is it always a good idea to leave that on? No effects on frame drops etc?

See my reply to Dave above re undervolting... seems to have made the temps worse!

Are you using stock case fans?

Nope, replaced the stock 120mm with a pair of FD Venturi HF-14 (using the low speed adapters to run them at ~900rpm, which feels like a good balance between airflow and noise... not that it matters because the GPU is so blood loud).


Thanks all!

Su

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.

God yeah use Wattman for all overclocking. Much more accurate.

Looking at the gpu power only draw in gpu-z it is pushing 220w and 248w, unless the v-core is being misreported then it shouldn't be anywhere near that, at that voltage and clockspeeds. I'm all for tweaking and trying to fix things before sending it back, but for the price it cost there's no excuse for what you are experiencing, so I'd say send it back, I think there is a poor fit between the die and the cooler.

Edit just to clarify that testing was in a game and not a torture test ?

Yup, was just playing Dawn of War 3 in campaign mode (borderless window) with the GPU-Z displaying on top.
