Think I can pull 5ghz? i7 2600k

post #1 of 10
Thread Starter 
Hello,

I'm still kind of new to overclocking but I recently got my build stable at 4.5ghz doing a 10 hour stress test using prime95. My CPU voltage is at 1.27, I notice that is pretty low compared to what some people have. One core maxed out at 65c the rest were around 62-63. With that low of voltage and temps (I have HT on so I could lower temps a little with it off) I could reach 5ghz? Or does the voltage and temps grow exponentially when you push past a certain point?

Any thoughts or opinions would be great.

Yeah for sure you could do 5GHz.

Voltages will grow exponentially on most chips @ around 4.8 Ghz, you may get lucky like I did and 5 Ghz will be your sweet spot. (mine needs 1.376 for 5 Ghz)

Every chip is different, but usually you'll reach a point where a chip requires a hefty voltage increase after a certain point. Can you get to 5ghz stable? Nobody can answer that because it's pretty much the same thing as asking if I'd win a hand of blackjack. The only way to know is to try

I'm not sure that I will do it quite yet. I feel accomplished just overclocking in general, but winter is coming up so that means lots of computer projects haha. Although 5ghz would be the greatest. I think my ambient (not exactly sure how to measure it) but my mobo reads 19c in the BIOS.

Sccr, I just wasn't sure if there is a trend or something like if you're at this point in voltages/temp you most likely would be able to reach X point

There's not. I've seen horrible overclockers with very low VIDs. Like I said, every chip is different. If anyone tells you that you're guaranteed this or that, they are either new to the hobby or don't know what they're talking about.

5GHz 1.376V and you are stable? That is a great chip, congrats! I don't know if I've even seen such low voltage for that speed.


OP, there isn't anyway to tell really. Some chips just hit a wall at a certain multiplier. Mine was at 1.28 for 4.5GHz too, until I tired to fold for a week straight to test stability. I finally settled at 1.32V and I've had no bluescreens for about 6 months now. I've never been able to boot above 4.8GH with voltages below 1.5. I haven't tested above 1.5.

Alright, thanks for the information. Just going to have to nut up and try it I suppose.

Day, I don't think I'd ever want to go above 1.4 I know there is a certain point around the 1.4 where it starts to degrade your CPU. If I wouldn't be able to hit it at 1.4 or less I wouldn't even bother

Yes Im pretty sure you can do 5ghz. I got my 2500k to 5ghz at 1.425v.
