I'm still running some tests. I bumped it up from 4.2Ghz to 4.3Ghz now and currently running prime95. Max temp so far is 76C and core voltage is at a stable 1.200V. Is this safe or is the voltage too high? My goal is to reach 4.5Ghz.

There are people running over 1.4v, but I would not recommend that, so the definition of safe is debatable.

From everything I have seen and read, provided you have an adequate CPU cooler and keeps your temps manageable, you can safely go up to 1.3v without worry at all. I don't think 1.3 to 1.35 is a bid deal, but I can't be certain for 24/7 use. For 1.35 to 1.4 I think you have to know what you are doing before using that all the time, and temps go up very quickly in that range.

Thing is he paid £800 for his PC...(it isn't even that special)

EDIT:
WOW....so unprofessional - I called them:
They test their stability with only 10 Gf's of IBT - if that was the case, I would be stable on 5ghz at 1.3v....
It is incredible how these companies exist and can sell a product like that.

As for OC - the "tech support" said that I could do it myself....yeah that would be the darn case if my mate didn't spend £800 with you!!!!
I go out of my way to use companies that have good customer service, it drives me nuts when it is clear they just don't care. Speaking of which, I was just having an issue with my video card, so I call Amazon, they overnight me a new one (and the new one works perfect), and give you a shipping label to send back the first one, no charge, basically no questions asked.

As for using IBT to find a stable oc, well from what I have seen that is quite literally impossible. It is nice to see how high temps can go in a worse case scenario, and as a double check to Prime, but I have found it useless in fine tuning. I could drop down a lot in voltage if all I used was IBT.

I found out something on my last Asus motherboard - Intel CPU overclock (on Crysis I), it seemed overclocking from 3.2GHz to 3.6GHz while there was NO increase in FPS is did smooth out the panning from left to right making things less blurry (Blurr was disabled). I went back and forth from 3.2GHz to 3.6GHz and immediately was able to recognize the difference, movement in the game was smoother so there must be something more to an overclock than simply increasing FPS!

I'm curious to know, how many times faster is a 4core CPU running at 4.5Ghz vs 3.5Ghz? Would a 1Ghz difference make that much difference in performance? Such as when playing graphic intensive games?

yea , it would,but its not how many times, but its about 25% faster, 4.5Ghz vs 3.5Ghz
so you would notice a increase in performance,
but in most games even stock can keep up, its not that you get a 25% in fps also ..lol
i do get higher fps tho smile.gif

edit,
sorry, thought you where asking about 3770K,
"4core CPU" could be alot different ones ..lol

Playing graphically intensive games has more to do with your GPU, and that is why many people spend a lot more on that than their CPU. For number crunching, it is as you would expect, e.g. a 4.4 chip will do the calcs 10% faster than a 4.0 chip. Google reviews of your chip and you will find reviewers that have plenty of graphs depicting an OC chip vs. a stock one.

So by OC the CPU I won't get any benefits when gaming? I thought most people OC their processors to get better frame rates?

Sorry, I didn't mean to imply that. Yes you will get increased performance, but that can range from being basically imperceptible to being quite noticeably better. It has to do with the particular combination of your chip, your video card, and what specific game. Some games tax the chip, some don't. Filling out your rig in your profile will help people answer your question, by the way.

Oh no problem I was just wondering. Sorry. My specs are i7-3770k, Asus p8z77-V motherboard, corsair vengeance 16gb ram DDR3 1600Mhz,

I'm currently testing now and I'm at 4.5Ghz @ 1.200V, Max temp has hit 80C. Is this good or bad guys? Should I go for 4.6 or leave it alone? This is starting to get addicting. But I must know my limits before I damage something.
