A long shot, try to reinstall the driver from a clean instalation, sometimes the drives crashes without warning.

1500w psu from Silverstone has 8 eight +12V rails.
Max Output Current: 40A, 40A, 25A, 25A, 25A, 25A, 25A, 25, 25A, 25A, 6A, 0.5A
Gtx 590 need 46A max at 12v.

I had the same issue once with Thermalteke 1500w. Driver crashes and random restarts.
I change it with a single rail psu, and all my problems are solved. Believe me on this I know, the hard way.

I have 4 590s at 1 rig, and as you can see it is going well when it has wu's.

I'm using two 25A rails, Silverstone said the psu is good enough to support 3 GTX590 cards w/load balancing. Like I said this crashing doesn't happen before 301.42 WHQL, just with 304.xx and Newer... And only while running Seti@Home...

Actually the GTX590 uses 28.67A, others including reviews have run the 590 on rails of 30A each, not 46A...

I spoke directly with Corsair.
I ask them if their AX1200 can handle 3 gtx 590 ( not the pc, only the vgas ) and the say NO.
590 run at 30-32 amp when doing 1 wu per gpu and climb at 45-46 amps when doing 2 or 3 wu's at a time.
Now i am using 2 AX1200, and the system works perfect.

Here is one list from the MSI forum I found at the internet about power consumption in amperes.

Of course an ax1200 won't do the job, it only has 100.4A on the 12v rail, to run 3 one needs at least 108A on the 12v rail...

Ok Tim, then explain why I'm having no trouble using either 301.24 or 301.42 with Boinc 6.10.58 with either an ST1500 1500w psu or a Maxrevo 1350w psu? Especially the Enermax Maxrevo 1350w which only has 30A per rail that I used for about 1 month?

Now I'm going to Quote someone that I normally don't, It's from Here...

There is a known incompatibility between Legacy Cuda 3.0 applications (stock 6.10) and Cuda 5 drivers.

There are several options:
- go back to a Cuda 4.2 driver (Where available)
- Use a third party Cuda 3.2 or newer build
- Use newest Cuda 5 WHQL driver and set a system environment variable, CUDA_GRID_SIZE_COMPAT=1

The last is a workaround to a quality problem found in Cuda 3's CUFFT DLL, that was introduced in release Cuda 5 drivers, after I reported the issue to nVidia. With multibeam v7 on the near horizon, it's unlikely this will be addressed in stock V6 builds.

Jason

I use the optimized v6 builds on the 590, which has its roots in the stock app and since I have no idea where to add the variable, I'll stick with 4.2 and the latest driver that supports 4.2 on Win7 x64 is 301.42...

So it's not a psu problem, as I have plenty to spare, just a software compatibility problem that is unlikely to be solved, at least as far as I've read.

I use the optimized v6 builds on the 590, which has its roots in the stock app and since I have no idea where to add the variable

In the environment, I would imagine: Control Panel -> System -> Advanced -> Environment Variables -> System variables (for XP, I don't have a Win7 machine at home to check if it's different there).

I don't see any advanced in Control Panel under Win7 x64, advanced might be named something else or just gone entirely and without asking, I'll pass, as 301.42 solves My problems.

Ok I found it, entered the variable in, although it had to be split into two parts...

I'm downloading 306.23 and I'll see if that fixes that...

Or even, with the exact pictures and copyable variable name from a live SETI cruncher. With both Windows 7 and Windows XP examples. Been there, done that.

Did you try to reinstall the driver after the problem starts? I have few hosts with Win7/64 (one with 590) and the last Nvidia driver works ok.

On the other side i see few months ago another user who have similar problem and at the end he find the new PSU was comming DOA. Just another shoot.[/b][/u]

I'm crunching with 306.23 WHQL, so far no driver crashes on the 590, I'm hoping an hour will be good enough, it's been crunching for about 10 minutes, so far nothing to report that's unusual...

No sea monsters either...

Ok, I've been crunching for about 1.5 hours and I've had no crashes what so ever, so 306.23 and 6.10.58 with that variable work fine together...

6.10.58 is the manager version, not the actual application that does the processing.

Yeah I know, it's Lunatics_x41u_win32_cuda32.exe, it's the latest that I have and I use BoincTasks 1.41 on top of 6.10.58 x64, I'm not having problems since I put in the variable, not after 1.5 hours of work.
