gpu new core id 15 slow

Postby apeman556 » Thu Apr 12, 2012 5:50 pm

Hi, I have 2 pc's folding 24/7, both running nvidia gpu and smp clients with no problems. Both of the gpu clients said there core was out of date and downloaded new cores (Fahcore_15). Since then,neither client has run at 100%, one is at 91% and the other is at 89% and I was getting approx 55,000 PPD and now I'm only getting 38,000 PPD. Whats happening and how can I fix this to get both gpu's back to 100% and increase my PPD back to 55,000.

New larger work units (704x something) and come with a new fahcore. With small WUs, data size is not an issue to performance. With these new larger WUs, the performance limitations change. See the existing thread on this topic... http://foldingforum.org/viewtopic.php?f=74&t=21208

It isn't a fahcore issue, as other GPU work units run with the new fahcore are still running at the higher usage. This issue is handling the larger WU. But as that thread indicates, the exact bottleneck has not been identified yet, or at least not confirmed in testing yet.
