okcnaline

I've recently bought a batch of dead GPUs mostly because it included a RX 570 and HD 7770. Most of the other cards were easy fixes. This RX 570 is the AXRX570-4GBD5-3DHD/OC. Fan continuously spin with consistent slowing and speeding. It doesn't send signal to monitor even after logging into Windows or Linux. It's picked up correctly in Linux dmesg as a Ellesmere, but "SMU" caused the GPU initialization to fail. In GPU-Z, the card was correctly identified as a RX 570 down to the default core/VRAM speed, but VRAM and core clock shows 0Mhz and VRAM shows 0MB. Devmgmt reports the card correctly but comes up with some sort of error 31 "driver does not match the POSTed". BIOS reflash was successful but nearly nothing changed. What is the issue with the card? (Note: I obviously know the GPU is bad. I also intend to fix it to the extent of a dead GPU core.) UPDATE: Decided to check which VRAM I have since none of the PowerColor RX 570's have Micron VRAM. TechPowerUp has their ROMs for the PowerColor RX 570's in a bit of panties. They had unverified ROMs that match the Samsung on my card but however many times I tried to flash the GPU, it maintains the Micron VRAM type and fails to show signal still.

Upgrading from a Quadro K620 and am a big AMD fan mostly for the RX 480. This is a workstation build; I plan on using RX 480 in MDA so that I still get acceleration and PureView in SolidWorks.

turkey3, you know me as okcnaline on Tom's. Why is NEXG T4? It's not that bad. And as for infinity, I've seen CX fail after 3/2 years. Some bought CX units 3 years ago and still does fine. So, depends.

Sorry for the late reply. I've taken the advice of Ryan_Vickers, and once I turned down my power to low, the Quadro miraculously stops folding when inactive, and RAM and speeds all around the computer is drastically improved. No more stutter for me! And seems like every answer here is a plausible idea of why my computer lags on certain things while others do not. Thanks again for replying!

@Whaler_99: I made a posts >2 weeks ago, and the problem with the Folding program not being able to use my GPU seems fixed. What the problem seems to be Windows 10. So with that said, I reinstalled Windows 7, and now it folds using BOTH my GPU and CPU. AWESOME!!! That's two WU's being done simutaneously. And the GPU does it around 4 times faster than my CPU. However, with that comes a new problem: my computer's stuttering using Chrome. Unusual. See my specs down below for more details. And the problem points to Core18, which to my understanding is the folding core for NV Maxwell cards (K620=GTX 745). It uses >139,000 KB of my RAM (~139 MB). Chrome uses that much RAM for >5 tabs, so it is very unusual. That can be compared to the FaH Core_a4, which utilizes cores and threads for Intel processors. That's 60 MB, where it usually is even for my older laptop, running Sandy Bridge. So what could've caused the Core18 to use that much RAM?

Hilariously, I can't fold using a Quadro K620; it says unsupported card, even though it has CUDA and OpenGL Acceleration.
