Keep this 4670K or try for a better one?

post #1 of 5
Thread Starter 
Hi Everyone!

I recently purchased a 4670K and I'm down to the last 4 days of my exchange window. Here's how it overclocks:

4.2Ghz @ 1.190v - 57c
4.4Ghz @ 1.305v - 63c
4.6Ghz @ 1.405v - 72c
4.7Ghz @ 1.485v - 82c

(Those are the stable voltages and temps it reaches in Prime95 on "In-place large FFT's" with an H100i)

Those numbers have been tweaked (cache voltage, cache ratio, VCCIN voltage, clockstrap, memory speed and voltage etc) down to maybe .005v. I've spent a lot of time with this processor and it's not really the temps I'm worried about since those numbers are related to synthetic benchmarks... What worries me is the voltage and electromigration. Real world applications have yet to see temps above 65c, even at 4.7Ghz.

I contacted the company I bought the processor from and they have no problem exchanging it if that's what I want to do. If this was your chip, would you go through the whole process of switching them out and mailing the old one back, or would you just stick with the chip I listed above?

Any thoughts would be appreciated! Thanks!

Personally I would try for a better one. I actually just exchanged a 4770k that was fairly comparable to that in terms of scaling and amount of volts required. Very happy with new one. Hit 4.6 stable at 1.24. 4.7@ 1.29(1.3 w/ xmp enabled for ram) and am working on 4.8 right now. It is fairly easy to swap out a processor so I see no reason not to, especially if it is purchased locally and it is just driving to a store. Online I might be too lazy/impatient, but that's just me.

Not that good but not terrible either, somewhere in the middle but I'd go for the exchange if it's convenient.

I think I'll try exchanging mine. 4.6 at somewhere between 1.2-1.3v is exactly what I'm looking for. If I just leave it the way it is now it will slowly drive me crazy haha. Thanks for the advice!

Just out of curiousity, would you mind testing AIDA64's stability test and reporting back? I've read that it stresses Haswell better/more than P95.
