Questions about overclocking an i5 4670k

post #1 of 7
Thread Starter 
I just got my i5 4670k 4 days ago and figured I would start overclocking (Z87-G45 motherboard) and have run into a decision. If I had to choose between a 4.2gHz core clock with a 4.1gHz ring core clock, or a 4.3gHz core clock and 3.5 gHz ring core (I think ring core might be called uncore on other motherboards? Sorry I'm very new to this) Which of these would give me better performance? Also these seem to be my limits any higher with either of these and the heat jump is huge, for example going from 4.3 to 4.4 and adjusting for stable voltage raises average heat by 10°C putting me in the 80° range when stress testing which I don't want.

So which choice? Also if anyone can suggest a better overclock it would be greatly appreciated.

My cooling is a Hyper 212 evo.

The cache/uncore makes very little difference to performance. Always sacrifice uncore speed for core speed.

80C in stress tests is still okay, as long as it is low-mid 80s. It'll still be 20+C lower in normal use.

So would something like 4.4 with a 3.5 uncore running intel burn test at about 80C be considered good?

That's at least average - good enough, in my book.

Sorry to bother you again but one of my cores runs about 5C higher than the rest for example with 4.4 a quick intel burn test read something like core 0 - 83C core 1 - 82C core 2 - 87C core 3 - 79C for the max temps. Is this a problem?

No, that's normal. You often see up to a 10C split.

Thanks for the help! I appreciate it.
