Will upgrading an i5 2500(non k) to an i7 4770k and OC-ing it give more performance?

37x+4X=41x103=4223MHz That's how much you can OC your CPU safely, I wouldn't try to go beyond 103MHz on the BCLK but 103 is fine.

Get the 4770k. With HT and OC you'll be bang up to date (within reason) and ready for another couple of years but the 4790k is prolly the best bet. The 2500 is a great CPU but already getting long in the tooth.

Where did you hear that? This seems to be an ongoing caution in the "Mem & Storage" forum. As far as I understand, Intel itself had stated that anything over ~1.57V for RAM would void the processor warranty.

It may well be the case, under a business logic for setting specs and warranty limits, that "it won't hurt your chip."

I thought it was 1.65v? or is that an older spec?

As far as oc-ing the 2500 is concerned, I tried but there isn't much difference between the stock speed and 3700MHz.

That's been most of my recent experience with OCing. If I get an additional 30% boost on top of my 20fps that'll mean I'm now at 26fps... still unplayable. If I'm going from 100fps to 130fps I don't care anyway... most of the time anyway.

Well, there's "what you read" [meaning OC-guides and spec-sheets from the manufacturer] and "what you hear" [meaning dialog among forum members, etc.]

The "spread" or difference between the vDIMM and VCCIO voltages was not supposed to exceed 0.50V. That's "what I read." "What I heard" was that Intel wouldn't warranty their processor for RAM volted above ~1.57/1.58. This might make sense, because the processors incorporate the memory controller.

IF you push vDIMM to 1.65V, vCCIO would need to be at least 1.15V. The consensus is that 1.2V is a safe limit. Of course -- I'm talking from Sandy Bridge experience here. I think these guidelines apply also to Ivy Bridge, but I wouldn't be so sure about Haswell. I might as well be up-front about my ignorance and blind spots.
