Seti at home 6.09 cuda 23
Pepi:
This stock application is faster on my machine then opt app.
Difference is speed is from 10-15% per results with low credit ( fast result) to 1-5 % per result with high credits (aprox 110 credits)
It also seem that this stock app works better on my GT 240 compared to second comp with GT9800 ( or maybe it is driver thing ( 196.21 WHQL)
Jason G:
Did you apply the 2.3 DLL's (to the opt install) Pepi ? (that installer was made before 2.3 was released, and an updated installer is in testing that will do it for you, if selected)
[Edit:] Since you're of squire status you may like to test it for us ? Making beta test posts about them shortly, but the installers are already in the beta download area.
Pepi:
Yes , both cuda 2.3 dll are installed :)
After night of crunching I can confirm: GT 240 with stock application and 196.21 are faster in any WU compared to opt app. But IT IS NOT CASE when using same combination of drivers and GT 9800 ( Green). In that case GT9800 (Green) are fast equally with 195.62 and opt app.
Of course I will test it, just now I download 0.35 beta and put on both machines.
Great work guys!!!!
Update: Reschedule work likes charm: all results from 6.09 are transformed to 6.08 without problem. Installer makes great job!
Jason G:
Cheers for the installer test!. Yep sounds like the newer driver 'funkiness' is playing a hand in the situation somehow. GT240, being a recent card may be a special case the newest drivers work best for, but others with older cards have reported noticeable slowdown with drivers beyond 190.38 & 191.07. Anyway, will keep an eye on things as nVidia will likely be juggling driver & SDK characteristics for a while. Keep using what's fastest for the card you have :)

For me there was little difference in speed on crunching using 191 or 195 Nvidia drivers on 9800 GT ( Green) with OPT app. But yesterday I was seen one user that uses 196.21 with CUDA 6.09 stock app, and he beats my crunching time on GT 240 with opt app. So I made clear install, use only software that BOINC download to my comp, and yeah, my time was compared to his times, so in that case 6.09 stock app was better then Opt app.
However the most unusual thing was that my card is 10% OC compared to his card, but I am not 10% faster :(
So more thing to find and learn :)
