Prime95 Error?

This is exactly what it says on worker number 4 when it crashed. Can someone tell me what this means?

Fatal Error: Reasulting sum 0, expected: 2.78059938976718e+124
Prime95 say hardware error detected, consult stress.txt file

  1. What are the specs for this system? Also, are you overclocking anything (CPU, GPU, memory)?
  2. Pretty new to using Prime95 but, I think that means that core 4 had a rounding error probably due to processor instability. Is your CPU overclocked at all?
  3. Yes. Its overclocked to 4.7ghz. I set the vcore to 1.325 and left the cpu pll on auto. I'm overclocking a i7 3770k on a gigabyte GA-Z77X-UP5 TH with 16gb of 1600mhz mushkin ram with 9-9-9-24 time settings.
  4. Drop your OC back in .1 increments until you get a stable Prime95 run. You may have simply overreached with your config.

    Already brought oc down to 4.5ghz and set vcore to 1.19 and set cpu pll to 1.65. Also do you think that overclocking the cpu while using the intel hd4000 graphics will cause my system to bottle neck? I only using the intergrted gpu for now.
  6. Even at stock speeds your CPU is more than enough to bottleneck the Intel HD4000 for any sort of gaming. The HD4000 is good for general use, but not for gaming as I assume your intent is for the OCed system.
