Just built another computer this time with the Intel Haswell 4670K. My last computer was a 3570K clocked at 4.4 so I am familiar with overclocking. When checking stock voltage when I first got the chip it was at 1.14v ramping up to 1.2 during Intel turbo boost. This surprised me because I thought that was pretty high to start off. I then tried to overclock it and the fastest I can get it stable was 4.2 at 1.277vcore, 1.15 cache voltage, and 1.90 input voltage. I've tried to hit 4.3 by increasing to 1.30vcore getting a boot and then instant crash. I am assuming a got a bad seed from Intel although I guess it could be my motherboard too: AsRock z-87 Extreme 4.
Im not an expert at OC so I may be doing something wrong. Any ideas?
