GTX460 and GTX295 combination.

<< < (2/3) > >>

Pizzadude:
This seems to have been a driver issue.  Completely removed older driver version and clean installed 258.96 and everything seems good.

Any suggestions ?

Any reason to use the older 258.96 driver? The newer one is 260.99. Have you tried it yet?

Pizzadude:
I went with the older version as I had been using that version with no issues for over a month and new it to be stable - well at least until this weekend.  Is 260.99 proving to be stable as I may go to that in the near future ?

A lot of us are using the 260.99 and I don't remember seeing anyone complaining. Seems very stable to me.

Have a question on a different subject though. I was looking through my inconclusive results and noticed someone else running a 295 and a 260. His 295 was showing as device one and device three with the 260 showing as device two.  Device three was the one that was throwing -9s. Are yours showing the same with the 295 split and the 260 in the middle? Seemed strange to me that it would split the 295 that way.

Pizzadude:
To be honest with you 295's (particularly the ones with double circuit boards - which I have) have very well deserved reputation for misbehaving badly with Seti and I have spent many hours chasing strange errors.  As of yesterday the 295 has been removed and I am currently running two overclocked GTX460's.  So far so good.

Is there any advantage to running SETI in SLi mode ?
