CPU Stability Problems?

post #1 of 10
Thread Starter 
hi, when i run 2 Super Pi, both cores go up to 100% usage then 3 sec later, one of them says "Error: non convergent in SQR05" while the other one continues. is that a problem with my stablity?

Also, when i run Prime95 and a Super Pi, my CPU usage on my second core doesn't go higher then in the 80s, it used to be fine but today the maxed out average on both cores was around 85, 1 at full load other at around 80. is this a hardware problem or is it fixable? thx

Bump up the vdimm a bit, not uncommon to need a little more voltage for stability.
But do memtest for sure!

Check the Quicky method by ncsa... about 1/2 way down in the link.
If all is well with Quick version, then do a full one to be absolutely sure!
