I am having issues with Fah, my main listed rig got a clean install , actually enabling uefi boot this last weekend.
Fah installed ok with Wcg too, and was working fine up to me using the pc today, it had tan all night without issues until I was watching the tube on it this morning.
Now I get a kernel power reboot whenever I run fah.

I'm working through some options, just about to clean install the GPU whql driver's to move away from the latest beta driver's.

But any ideas, is it just me?

New to me. I would try the older driver as you suggested. Maybe try a different (AMD)GPU

All my pciex slot's are in use for nvme drive's and the GPU is in a custom loop , so that's a tail end of issues option but Ty I'll try driver's first plus disable GPU acceleration first.

And various limb crossing obv.

@windwhirl Ty I'll try that.


Update.

Whql driver's plus reinstalled fah, seam's to be ok now I'll be back if the issue return's.

Cheers guys.

So after an HR fine , I had issues again , I found a incorrect for uefi key set in bios.
FTP reset key enabled I disabled it as it normally is.

This fixed my issues with Fah.
Just for any following, I am still having a specific crash issue but not while folding anymore.

Daft question @theoneandonlymrk, but have you tried it without the NVME drives installed at all? I wonder if too many lanes are being used without enough bandwidth possibly?

I have not added any recently I have tried a system refresh since it happened again, it's weird though , I'm not sure what it is ATM but folding while crunching seams to trigger it.
Hopefully the refresh works.

On second thought , I always have the protein viewer open recent simulations Have looked mental, two big ,very big protein clusters with a shower of molecules circling, normally theirs one big protein and the molecules.

Why oh why is it so hard to get FAH working on a Linux box?

I spent an entire day (wasted) setting up my dual CPU Xeon box to run Ubuntu 20.04 LTS. I installed the deb packages from FAH and after jumping around to get Python2 installed (required for FAHControl), it just will not start - Error in reading new core download. I can download the core using Firefox (and it works on my Windows box - so no firewall issues). Tried everything to no avail.

Also, got my Nvidia card running on nVidia drivers and installed OpenCL and CUDA but FAH just says OpenCL and CUDA not able to run..... again, no idea how to resolve this. I gave up and went back to WCG - installed BIONC and running in 10 mins.
 
@Russ64 I feel your pain at the moment. I run F@H on centos7. For some bizarre reason, after doing my normal periodic check on the client, the GPU Slot I set up a few weeks back pulled a Houdini and plain disappeared. Re-added and after the client trying like 8 times to connect to the work server, I got a WU for the GPU. I wonder how long it has been gone...
 
Hey guys, whilst the sun was shining a little I've set FAH to run, but I've noticed there some really poor scoring units floating about... Anyone else seen these??

16000 points for one unit?? Don't want many of these guys!! :(

Summer units :D. They hardly forces the GPU to hit 3D clocks. Yes I get them on my 2070/Windows, not on my Linux 2070 S

Edit: Correction I just got a 13413 on my 2070 Super. 1.4M so not a big hit. Consumption at the wall is down 110 W from the 2.2 M units.

None other than the usual I think. My PPD/W is OK on the 2070 Super but the 2070 really take a hit.
 
It kills it on the two 1080 Ti's and I don't think that the 1070 I have is of much use either... Oh well :)

What is the reported Watt? HWinfo give me 53 W average on my Win/2070. Normal is 180 but 1.5M. Now I see 345k. If this happened during Winter I would be freezing.
 
I was getting much less than 1m a day and normally it can be around 2.5m or better... Right now...

2 x 1080 Ti...

1070..

That's a little more like it... :) Ti's stuck at 1873 MHZ ish and the 1070 is around the 1860MHz range... All on non standard power settings and fan curve :)

On my windows 7 machine, i can't get my GTX 1080ti to use CUDA. It use OpenCL all the time.
Any way to change this?

EDIT:
Seems this is caused by rendering the windows 7 desktop on the same card running F@H.

I also don't see any mentioning of CUDA settings in my nvidia control Panel.
Do i need to do something to make the control panel show CUDA settings? (I' m on driver version 388.13)
I see a NVCUDA.DLL is installed (NVIDIA CUDA driver 9.1.75)
I am reluctant to upgrading the driver, to avoid issues with FSX.

I'll have a check when I run mine (Sadly running Win 10 1903 OS here) but it might possibly be down to Windows 7?? I'm not sure, I just tell FAH to run and it does, CUDA or not, I just leave it do its thing! It might be me dreaming but I'm not sure if CUDA will slow things down or not?? ..... One of our Veterans might be able to help there :)

It’s not a Windows 7 issue. My 2070 is doing just fine. I had one problem with Linux but a re-start took care of that.
 
I've had a check on FAH today since the sun is out, the crunchers are folding as well :) I've seen this in my logs this morning...

It should be setting it to CUDA automatically then I'm guessing as I've not touched any of the settings. I just leave FAH do it's thing when I run it :)

Same here, FAH did its thing. I do have a newer driver (430.64 with a CUDA driver 10.2) than @Jacky_BEL. Update?
 
I'm on 436.02 driver at the moment @mstenholm

It seems to be doing ok I think? :)

I think that @Jacky_BEL needs to consult THIS. I don't know if the old driver is the problem but the F&H forum is a better place to discuss matters since we obviously didn't have to struggle with it and hence doesn't have a good solution.
 
OK,
Maybe when I upgrade FSX I can upgrade the driver too.

I can't remember ever installing CUDA sdk toolkit.
I 'll try to dig up something else from the log file

I get following message : CUDA_ERROR_INVALID_PTX (218)
According to info from the folding forum and Nvidia CUDA toolkit release notes, i need at least CUDA version 9.2 (driver version 397.44)
(Info here and here)

Just did a test on another machine with a MSI GTX 980 Ti on windows 7.
Driver version was 391.35
Upgraded to 399.24 and sure enough F@H started folding on CUDA.

So I now upgraded the GPU-driver for the Asus as well to 399.24, and now it is also folding on CUDA.

It should speed things up depending on the card you run:

Here is a link with an updated ranked list of GPU models and recent data on F@H performance.

I have my 2 1080 Ti's and a 1070 at present that will fold whenever I produce enough solar power :) It's pretty expensive running these things 24/7!! :laugh:
 
I wonder if I should use my old GK110 titans for folding since they have good DP performance ?
