GTX295 CUDA Issues

I had suspected this so I installed a brand new Corsair 750w nearly two weeks ago. I wired the system so only the boot drive, motherboard, DVD writer and GTX295 were connected and for the following 5 days the problems persisted.

Interesting, can you clarify the 'all other CUDA apps work flawlessly' bit?
I have read that this is an issue with the older dual pcb versions over on the seti forums

My GTX is the dual PCB version and I suspect the issue you refer to is the bug in the memory controller, so far as I can make out this is more of an urban legend rather than actually confirmed by Nvidia.
As I said other Cuda apps work with very little hitch - the ones I currently use are Badaboom, TMPGENc, Adobe, Boinc Collatz Conjecture and GPUgrid. Boinc Collatz Conjecture throws occasional errors but nowhere near as many as Seti.

Can anybody explain this error, suddenly getting lots of these now :-

I am currently running 197.45 as this is the version recommended for Cuda support in Adobe CS5.
Which version are folks using for Seti ?
