I have seen various numbers around the web on what the max temperature of GDDR6X is. It seems like the manufacturer would know best on the matter, this is why I only believe this number:
Op. Temp. 0C to +95C

So why is the 3090...
I can confirm that the new HWiNFO does indeed show the memory temperature. I can also confirm that the perfcap happens at 110C. While mining at STOCK speeds on my Eagle OC, I sit at 110 the entire time.
I added three active heat-pipe M2 coolers over the memory. They are instantly getting very hot, which means they are transferring heat off of the card quite nicely. I wish I could read the memory temperature for the card, but ya know.... that is privileged information that NVIDIA does not think...
That is an interesting idea. Based on that idea, I did some testing.
* I was mining ETH continuously through all of these tests to put thermal load on the memory *
Test 1. Stock clocks. It had been thermal throttled all day, then I added the box fan on high, basically replacing my case side...
I do not. I am basing the claim that it is likely memory temperature on a few things.
0. GPU-Z shows "PerfCap Reason Thrm" and the performance takes a hit. So we know that something in the card is getting too hot, because the card is saying so. The GPU is cool as a cucumber when this happens...
Confirmed that reverting the driver resolves the problem.
Also, it turns out that the cards will even Thermal PerfCap at STOCK speeds after a few hours of ETH mining. Awesome....
I would love to hear from another 3090 owner. This is horrible.
Something changed with this driver and my ability to overclock the memory on my 3090.
I believe they changed the thermal limit of the memory, reducing it significantly.
With previous drivers, I was able to run my memory at 10350mhz under full stress-test load. With the new driver, I pretty...
Thanks! That worked.
Currently running at 953mhz @ 1.26v
SmartDoctor rocks for fan control because there is an option to set 4 different thresholds.
I have mine set to 65 for step 1, 75 step2, 80,85. The result is that the fan stays a little over 30% idle(nice and quiet) and a little...
I have an HIS 6950 and have installed the ASUS 6970 BIOS linked by the OP. The card works fine, but when I try to start SmartDoctor I get the following message:
"Can not find graphics card information"
SmartDoctor then immediately closes.
I have tried uninstalling all Asus and ATI...
