What part of the nVidia actually does the math. The cores or the Shaders?
I'm wondering if I need to overclock one the other or both. I am trying to get the max with out over heating my nVidia cards.
Any one know for sure?

The engine core freq increase gave smallest speed increase so far. And very poor in OCing.
Memory give some speedup, need to be measured still (I still check upper memory freq OCing limit). It was reported on beta that shaders freq gives best speedup.

Thanks.. I'll kick the shaders up a bit and see if that works.
Thanks again for the hard work on these mods. They work well.

Any ideas? I can't get the modified AP apps to work. I have four modified AK apps working, but four regular AP apps. Also running the CUDA app for 9 process total (using i7).

Upgrade to V10 or take AP v5 section from V10 app_info file.

Hello i use boinc v6.6.20 on windows xp pro sp2
cpu Q6600 with a gpu 9600 GSO 512 mb.
nvidia driver 18250
i downloaded the package Raistmer's_opt_package_V8_CPU_GPU_team.rar
with gpu number 1
with <ncpus>5</ncpus>
i run other projects along with seti on this host.
there is always 5 tasks running instead of 4, however i see no cuda running, i see only
setiathome_enhances_6.03 and only "running"
and by seeing my tasks, an average os 700 seconds for a seti block is norma cpu time.
(the 9600 gso should do it in approx 160-170 seconds)
gpu crunching is checked on the setiathome website preferences page.
I think that the correct cuda seti worker application was not downloaded.
how do i do that ?
