HD6790 x17 issue.

Hi guys great work on the 7.4.4 Client, at last my GPU actually folds the only issue I'm having is that there is no way any of the x17 WUs will finish in the allotted time.

Are there any flags I could use to avoid x17 WUs for the time being as the HD6790 is just not up to the task :(

Thanks in advanced.

The only way to avoid Core_17 projects is to run v6 of the client.

Sorry I should have mentioned my HD6790 will not fold at all with either v6 or v7, it only started working with the recent v7.4.4 Client.

Welcome to the F@H Forum wraithguard,

Unfortunately, FahCore_17 is the only way that AMD GPUs can contribute now. FahCore_16 has reached end of life (https://folding.stanford.edu/home/core1 ... d-of-life/) and thus, once FahCore_16 Projects are stopped, you will only get FahCore_17 WUs on the supported GPUs. Are you using the latest AMD Drivers or not?

My HD 5450 has only 80 shaders and my HD 8338 has 128 so it's not surprising that neither will finish the assigned WUs. I do understand what you're saying.

According to my information, the HD6790 has 800 shaders which means it should finish in time. Are you stopping and starting the client frequently or does it run 24x7?

Yes I have the latest drivers and CCC I've even gone as far as rolling back through the last 4 drivers and still nothing.

I am shocked at the poor performance of this GPU I've had 2 WUs time out now I even leave a CPU core available for it.
They are left to run 24/7 it averages 12k PPD but yet the estimate on the jobs are like 20+ days... I think it might just be that the "Barts LE" is not up to handling these tasks.

Post your log, the time estimates might be off in the client. The most recent version of the folding client does have improved estimates on time to completion, but they are still not accurate in all cases. Older versions were worse on the estimates. I have done some test runs on a 5870 installed in my son's Mac Pro when it was booted into Windows 7, and it would complete WU's with plenty of time left until the deadlines. Your 6970 should process at about half the speed of the 5870, but that should still be good enough to complete WU's with time to spare.

I have not been able to test with the most recent Core_17 WU's, but might be able to in a week and a half when my son is away for the weekend. But my observations from the prior WU's tested should still hold.

This is where I got to with it, if you think this is normal I'll leave it running.

Without posting a log, we can't see details that we would need to determine if you are getting a good PPD or not.

A screen capture of FAHControl is not useful for determining actual ETA's. The log file would be. You can find information on posting logs here in the Welcome to the F@H Forum topic. There are separate directions for the different OS's.
