Haswell i5 4670K/i7 4770K batch and o/c results

[Krautmaster]

I just did an IHS removal on an i7 4770K, I should have check the quality before I think.

Temps are stunning good now compared to standard, Batch is L347B947 - stock Voltage 1.048V

Any how, the CPU seems to be a very bad OC CPU... 1,2V @ 4.3Ghz seems not to be stable, that sucks as others do 4.6 and more with that voltage. I don't have an idea what I might do wrong, but at only 1600 mem speed I only can imagine that the cpu voltage is to low and causes BS in prime 95 load.

Voltage Limit in Linx, which stresses the CPU massively, are ~ 1.25V which results in ~85C - daily workload or Prime large FFT are less than 70 in this voltage.



Edit: Prime 95 large FTT Temps are far much lower even on high voltage:



-> 1.35V -> 4,5 Ghz not Prime stable, sucks
