My son built his computer and overclocked it to 4.2. Now my question is this. If load line calibration is on Standard [which disables it] then Prime95 won't run . If it is put on Level 2 Prime95 has no problems. The Gigabyte manual states "Note:Enabling Load-Line Calibration may result in damage to your CPU or reduce the useful life of the CPU." His VCore is 1.3625. I don't understand ,because I just built 2 computers with Gigabyte boards and neither of my manuals have that statement. I know that half the people say they use it and the other half say they don't. He tried disabling it and bumped the VCore up but Prime 95 still wasn't happy. That I couldn't figure out.
