i5 4670k 4.2ghz 1.217v

trying to overclock the i5, realized i must have a pretty bad chip out of the bunch.
all i've done is upped the cpu clock ratio to 42 and the vcore to 1.2 and increased till i was somewhat stable
max temps running p95 is 62c, cooling it with a h100i
mobo is the gigabyte z87x-ud3h, also have 8gb vengeance ram installed with a xfx 720 watt black edition power supply

are these temps and voltages safe?
Thanks

  1. They are perfectly fine. Better than mine actually. I'm also running a 4670K on an H100i. Here's my CPUZ.

    just had to up the core again because getting this message in p95

    FATAL ERROR: Rounding was 0.4939425975, expected less than 0.4

    When I overclock I can't say I'm that good at fine tuning.

    I just turned up my clock high and started at 1.2V and everytime I crashed, I lowered the clock down .1 and then see if that ran. Rinsed and repeated until hit a stable point.

    Then I try to work my way back up within a TDP of about 70C (I think the max TDP for a 4670K is around 85C). I just ended up at 1.224V and 4GHz with the most stability at temperatures I found suitable. Every chip is different. Mostly just trial and error I suppose. Hard these days for me to find the time to do such stuff with my PC as I'm pretty busy.

    Wow I just went off rambling. In other words what I should have said was lower your clock a bit and see how that works out. If it's stable increase the voltage (I'd say around .040V for each individual MHz) and the clockspeed and see how it turns out.
