MW@Home, N-body simulation, all have "computation error" after 2 seconds of time

[VirtualLarry]

Anyone else seeing this?

The rest of the MW@Home CPU WUs ("MilkyWay@Home 1.00") calculated correctly.

I think, but am not sure, that the N-body simulations are multi-core.

Are these just bad WUs? The computer seems to be stable, although last week sometime, for the first time in a long time, the computer had rebooted on it's own when I wasn't watching it.

It's a Q9300, overclocked from 2.5 to 3.0, at stock (default) voltage. Was always OCCT 64-bit linpack stable for an hour when I tested it. Maybe it needs a boost in voltage now?

Thanks. That explains it. Bad WUs.

I'm not sure the linpack is a good test really, it runs the cpu unrealistically more hot than any other programs I've seen.
Also 1hr isn't long enough, personally I run the normal OCCT test for 24hrs (I've seen failures at 17-18hrs!), if it passes that it's good.
And because test temps are lower you can run a higher overclock .
