I can't tell if this is a hardware or software/driver issue or if we've classified your GPU incorrectly, but

Code: Select all

14:55:39:OpenCL Device 0: Platform:0 Device:0 Bus:NA Slot:NA Compute:1.1 Driver:1.4

indicates that you have support for OpenCL 1.1. The minimum requirement is OpenCL 1.2
Certainly the statement

Code: Select all

specified module could not be found.

indicates that some driver software is missing.

Welcome to Folding@Home!

https://www.techpowerup.com/gpu-specs/r ... 7610m.c377

There are two prerequisites for Folding@Home for Nvidia and AMD GPUs: it needs to support OpenCL 1.2 (some GPUs that only support OpenCL 1.1 have all the parts of OpenCL 1.2 that F@H uses) and 64 Bit Floating Point math.

Your GPU does not support 64 Bit Floating Point math. There is no way around that.

Posted: **Fri Jan 08, 2021 5:29 pm**

Yes, the GPU is not classified correctly. None of the Radeon HD 7600 series GPUs support FP64, desktop or mobile. The HD 7700 and above desktop GPUs in the HD 7000 series cards do support FP64, and it appears the same holds for the mobile GPUs in that series.

There are several entries that used to be correct at not listing them as supporting FP64, it appears someone has modified the file. I will see if that can be corrected.

One clarification:

The part about some GPUs that only support OpenCL 1.1 only applies to some nVidia GPUs. These are Fermi based cards, they support some, not all, of the OpenCL 1.2 parts that F@h uses. It also depends on which Fermis chip is used, they have different levels of 1.1+ support. Depending on the folding project, WUs may successfully process on these cards, but a different project will fail.

AMD adopted OpenCL 1.2 early on, any of their cards that support FP64 also support at least OpenCL 1.2 as well.

FAH used to enable a limited number of very small projects for devices like yours but they've quit creating such projects just like managing a limited number of very small projects that can run on a 32-bit OS. Support for managing separate queues of projects isn't worth the extra overhead of managing and extra queue which is perpetually empty.

Both of those features have been deprecated since they expect there will be no such projects available in the future. The GPUs should be disabled in GPUs.txt.

It's a CPU core (A7) that is failing ... his GPU is already disabled ...

Is there a Windows Event logged at the same time the core crashes ?

32bit os? ... didn't think these were supported any more

It depends on what you mean by "supported"

The FAHCore that was written for 32-bit still exists so if you manage to find a WU that's enabled to use it, it will still run. All large proteins require mixed precision (which requires a modicum of FP64 instructions.) Small proteins can be processed on a 32-bit OS with that FAHCore but I suspect that the default construction of all new WUs will request 64-bit. Thus if your system is seeking a 32-bit assignment, you probably will get VERY few assignments.

I have one PC with a 32 bit OS it gets Core_a7 WUs just fine. (I have not checked for Core_a8)

Some Points:

No GPU folding is for 32 Bit OS, the AMD and Nvidia drivers do not support it. (I suspect it would work if the drivers did)

A '32 bit OS' uses 32 bit integers and addresses, F@H is all about Floating Point math. Intel has supported 64 Bit floats since the 8087 in 1980. Current F@H needs SSE2, which was introduced in 2000.

There is an issue with OSes up to Win 7 Service Pack 1 where it does not save the AVX registers on a task switch, which makes a modern OS mandatory. Linux is the same time frame.

So if you have an older OS (32 bit or 64 bit) F@H can't do AVX math, only SSE2 on your CPU.
If you have a 32 bit OS, you can't fold on GPUs.
If you have MacOS you can't fold on GPUs.
If you have a modern AMD GPU (RDNA) you must use Core_22, Core_21 is not supported. (It is possible that Core_21 will never reappear, but not announced as such)
If you still use a 'Fermi' Nividia GPU, you can't us CUDA in F@H. (Fermi was current in 2010, superseded in 2012. The last new Fermi may have been 2014's GT 705)
Your GPU must support 64 bit Floating Point Math and should support OpenCL 1.2 to fold. (There are rare instances where OpenCL 1.1 works on Nvidia Fermi cards)

That is a lot of arcane rules, and I may have some wrong, but that is what I think I know.

Looks right to me, but if somebody is exceedingly lucky, they might do better ... but FAH does not support drivers that no longer have the GPU manufacturer's support. We don't build drivers.

If you have MacOS you can't fold on GPUs.

That's a direct result of nV (and probably AMD) deciding to un-support 32-bit drivers. I'm not sure what would happen if you managed to find deprecated 32-bit drivers from those folks.
