Tahiti & Pitcairn GPU Folding

post #1 of 12
Thread Starter 
So, ive seen articles and threads (from other sites) with PPD numbers from 79xx and 78xx cards. Some instructions say to use the 12.2 driver, or other instructions, all which i have tried only to fail.
I know the current core isn't optimized for the new architecture yet, but id like to get my 7850 up and folding anyways!

Any 1st hand experience or a link/instructions would be greatly appreciated.

I've not seen anyone succesfully fold on them yet, but that doesn't meant it's not possible yet. It's been a week or more since I heard of somebody try to get them to fold and couldn't. Best I can tell you is to use the latest v7 client with the advanced client type, more info in the "FOLDING" link in my signature. Past that, I don't know very much about AMD folding.

I'm currently folding on my 7870 CF setup. Getting around 7443 to 7771 ppd each on the core16 WU's (11293 in particular). You have to follow the instructions on this site and if your GPU device ID isn't there follow the second link and a ticket has to be opened and your GPU has to be whitelisted:

http://foldingforum.org/viewforum.php?f=83

Obviously these aren't optimized yet, but the new optimized clients/cores are something that takes quite a while if it even gets fully optimized at all.

My 7770 is doing 6k PPD at 45°C with only 20% fan speed. upsidedwnsmiley.gif

Not a Tahiti or Pitcairn I know but though I'd throw it out there.

That worked perfectly, thanks for the link!

My 7850 @ 1050 core is doing 7000-7100ppd @ 35% fan @ 55C. Thanks for your numbers, thats pretty solid considering that the 7770 sips power!

It takes a full CPU core though to keep it well feed. So not folding on it at the moment.

I've found that just leaving it 1 core on my quad core at least, doesn't give it enough resources. When I run SMP 2 instead of SMP 3 the ppd on the GPU client goes up. Not sure what would net most PPD: SMP 3 + GPU or SMP 2 + GPU

I also get less PPD penalties when watching media or browsing the web with SMP 2 + GPU since I have one free core to do other things.

I also switched to just running 1 GPU client since for some reason when I'd run both the second CF'd card would drop to lower core clocks and would kill it's PPD.

You try disabling CF to see if it fixes this?

No it didn't occur to me to try this, would disabling CFX still let both cards fold?

Yep and it has fixed usage issues for many in the past. Only pain is you'd have to re enable CF when you want to game, but give it a shot and see if it helps you.
