I7 950 voltage overclock

Hello,
Hey guys i would like to ask why does sometimes my core #3 in core temp has only 50 percent load? Im running P95 large fft. I overclock it by 4009 mhz. I think after 30 mins of running p95 core #3 will down its load to 50%? Is my temp good for stability? Im just aiming for 4 GHz on air coolers. Thanks

i7 950
cooler master v10

  1. Is that core temperature, or cpu temperature? Try to keep your cpu temp under 70.
    ...Which is a bit high for your low-voltage overclock, and the vcore you're running. That cooler should be enough, though, so maybe it's just a sick cpu. Try running benchmarks and compare the numbers with people using similar setups.
  2. Have you made sure error checking is enabled in Prime 95?, maybe Core 3 encounters an error and so stops working.

    Also your uncore frequency is alittle high, it should be double your memory frequency for maximum stability.
