Core 21 failing almost immediately

So, as said in the title, any time my graphics card (a HD 6950 1GB) tries to run a WU, it'll just either fail it outright or immediately send it off. I've tried reinstalling the client, reinstalling drivers and underclocking and overvolting the card. Here is the log for 2 examples:

It would be helpful if you posted the first couple pages of your log.

I've see a number of folks who have had troubles with the Crimson drivers. Can you find a Catalyst driver that works with this hardware?

A HD 6950 is a 7 year old VLIW4 microarcheture, (terascale 3) that supports OpenCL 1.2 I am not sure Core_21 works on any AMD card that is not GCN.

The Cayman Pro was once supported but it may have been excluded from the active projects because of its poor performance compared to later devices. In fact, when using a GPU of that era, it shares the processing load with the CPU -- and configuring the FAH Client to fold with the CPU gives almost the same throughput.

In any case, you can try it with the Catalyst driver.

In any case, we need to see the first few pages of FAH's log. (See the signature block of my first post here.)

Ah I see. But I mean.. every little bit counts, right?

Just to make sure I don't post something you don't need, you mean basically everything from the start of the log file in %appdata%? Also, yes, I'm going to try catalyst drivers now.

EDIT: Yeah I just installed Catalyst drivers and it's now folding properly. Hey, it can match my 6600k when that's folding a7 WUs at least :P And thanks for the help.

You can right-click on FAHClient's Folding Slot on the Status screen and select Finish to finish one and leave the other running. It takes quite a bit of time for the PPD to stabilize.

You might try running either slot by itself until the PPD stabilizes and then try both. I expect that running both will slow both of the others down some, so the total may or may not be better than either one by itself. A few days of experimenting may help you make the proper choices.

I am running Windows 10 Pro 64 bit, with AMD Crimson 16.2.1 drivers.
I have the same issue on my 6950.

For such an old GPU, the latest drivers you used AMD (Crimson 16.2.1 beta) doesn't provide OpenCL support.

To be able to fold, you need to stick to the previous release (Catalyst 15.7.1).
