Essentially I think I have a defective Intel cpu (what are the odds?) and want to confirm whether or not this is true based on forum input before I contact Intel.
The cpu is an Intel Xeon E3 1275 V2 which is in a workstation to run a computational chemistry program Gaussian09.The other day when I was running Gaussian, the computer screen suddenly went black and then the compute prompt said that the computer has recovered from a serious error, boot normally? I was like w/e and ran the same job again, and the exact same crash occurred around the same intensive step of the calculation. I was suspicious of system stability so I ran Prime 95. Here's the kicker, it crashed within seconds of running small ffts (max ftu l2 cache tested.) However when I run large ffts, everything works fine for 1+hr. So is this a cpu problem? The psu is working fine, I already tested it. Ram is also functioning correctly. I actually just replaced the mobo via Asus rma, as it would not boot last month giving a "diag cpu led". I dismissed it as a mobo problem and the new board did boot but now I'm not sure anymore. The computer functions normally until I apply stress to the system, which is probably why it crashed in Gaussian.
Could some people please give some input on this situation.
Thanks for the help!
Edit: forgot to mention. This is not a temperature related problem. Using a corsair h60, temps typically range from 28-59C always.
