Longer Load Time with New GPU Board

<< < (2/2)

Pappa:
You might consider "reinstalling" the 191.xx driver package. As nvidia went to a more universal installer of a larger size, it could be that refreshing and insuring that features of the "newer card" are properly being installed/utilized.

Purple Rabbit:
Thanks Pappa,

I'll try that. I think everything is running like I thought, but a reset to known good values can't hurt.

The initial 10 second discrepancy on start up is almost inconsequential, but the engineer in me had to ask why.

Purple Rabbit:
Thanks again to Pappa. Reinstalling the drivers (actually I put in the new 195.62) solved the "problem". Being just a Silly Wabbit I thought (dangerous!) that swapping one board for another where both used the same drivers would be a plug-and-play. Clearly it wasn't...sigh

Edit: This turned out to not be a wall clock time problem (they were about the same for multiple tasks), but a CPU efficiency problem. The CPU was being used (so it says) much more than needed. This is now (I think) been remedied with the reinstall of the drivers.

Pappa:
Things that happen at the OS level (users never see) tend to confuse things. More than once I have been forced to swap hardware (due to hardware failure) and on restart seen various problems even though it is the "Same Type of Device." History has taught me that when playing with hardware changes "Boot into the Safe Mode," and then resintall drivers. Reboot and things are normally happy, the OS sees the hardware and then automajakly knows where the drivers are .

Gizbar:
See you've gone with the 195.62 drivers. I've just taken them off my 2 rigs, and gone back to version 191.07. The 195's were unstable on my Win7-64HP rig, but seemed ok on the Vista-32HP rig.

Kept failing with 'Nvidia driver has stopped responding but successfully recovered' message. Every time it failed, it would forget the WU it was working on, and start a new one. I had about 60 part finished tasks, even though there is a GTX260 and an 8800GTX in there. When it failed 3 times in an hour earlier, I'd had enough.

Went back to the older version, no fails, and it is now reducing the 'part-finished' WU's by completing them.

regards, Gizbar.
