Could that be ? Nvidia Beta 313.96

Not long ago AMD released a new driver which was ~9% faster than the earlier one. They said, they found (and fixed) a bug in the clock driver routine.
So why should nVidia be error free?
As Murphy said:
If it happens, it must be posssible!

no good news, back to normal

no good news, back to normal i think. it was a "one day fly".

cpu usage raised by 100% , and so wus took again 600 seconds more. They all different. cant fix a score.

It's a bit of a hack, but the way I measure performance is to take a copy of a current job and run it standalone (i.e. not under BOINC). Somewhere I read that BOINC applications can be run directly so with a bit of fiddling (delete status.cpt and the output files) you can run the apps directly and measure the exact time taken. Although I've only done this under linux, I guess the same trick will work for Mac and Windows.

Here's my scrappy script:-

#!/bin/sh
#
PROJPATH=../../projects/einstein.phys.uwm.edu
export LD_LIBRARY_PATH=.
#
# Delete old result files
/bin/rm -fv $PROJPATH/*2336_0_*
#
/bin/rm -f status.cpt stderr.txt
#
time ./einsteinbinary_BRP4_1.31_i686-pc-linux-gnu__BRP4cuda32nv270 \

On linux, I run it as "time sh runjob.sh", Mac OS I guess will be the same and Windows equivalent is probably similar (but need to be a .BAT and use whatever it has in place of the 'time' command). You need to get the command line from a current job though (as the above is specific to my set-up).

And that makes me think that if there was a "standard candle" job we'd really be able to tell the difference between drivers, cards, etc!

sorry i am not familiar with

sorry i am not familiar with linux etc. i dont think get the job done ;)

i am also poor in installing nvidia drivers under linux, if i would start that "project" it will take weeks, i swear. XD
