Hmmm.... It's possible your chip is as stated -crappy BUT there are still one or two things that might make a difference.
Can't hurt to check.
I don't know if you've been using the same PSU with both/all chips but if possible, check to see first what your rails are putting out to make sure all is within spec.
I know with Socket A's the -5v line must be rated for at least 28W's of power or it won't clock so well - It should also have at least 5v's or better.
As long as the PSU is producing the required power, all is good in that example.
You can check the voltage with a meter and it should fall within spec or maybe a tad higher for each rail spec that's listed on the PSU's label. Be sure that the specs of the PSU says it's rated for the proper wattage to the CPU itself/CPU power supply circuit, if it's starving for power you'll have crappy results and it doesn't matter what CPU you use with the system.
If it's getting all the required power from the PSU rail to the board's CPU circuit, then I guess that's all that's left - A crappy CPU.
BTW I'd still try a run with P95 and HWmonitor logging temps in the background as the run progresses just to see exactly what and how it's doing.Edited by Kryton - 5/29/11 at 12:05pm
