3930K at 5ghz, how hard is it?

post #1 of 10
Thread Starter 
Not seen many stable 5ghz 3930k's knocking around, how difficult is it to get a 3930k to 5ghz? Whats max safe volts on these things?

It isn't easy for 24/7. The hexcores do tend to run hot & it's tough to keep temps under control with higher clocks & voltage.
It's hard to say for voltage, it's still sandy bridge & not really strong. up to 1.45 or so is probably reasonably safe (but can't say for sure). I regularly run 1.5 - 1.6V with sub-zero temps for benching & have seen a fair bit of degrading, it keeps needing more volts to run the same clocks.

damm I thought they would be same as the 2700k's for heat.

What you think to haswell ftw? picking one up?

I think haswell is going to run hotter than Ivy, with the integrated voltage regulator. Even though it's probably efficient in the high 90%'s, it's still moving heat from the mobo into the socket.

I'll be getting haswell for sure, just hearing about how the people testing them are doing makes me want one.
I was kinda hoping to see ib-e first, my sb-e is getting pretty run down & will need to be replaced, didn't want another sb-e with ib-e getting closer but I might have to.

Have you seen some Haswell overclocking results?
post #7 of 10
Haven't seen anything, only heard that it will be fun for extreme coolers at least, hopefully that means more fun for air & water coolers as well.

Really hard. It took me about a week and a half of fiddling to finally get it to even load Windows above 4.7(11x47) I finally managed to get it to boot right at 5 with BCLK at 125, and much lower multiplier, but at voltage I'm not comfortable with: 1.568v. Obviously that's far too high for a 24/7 OC, but not enough for any sort of extended stability testing.
I should just see what I can squeeze out of this chip, then trade it in for a new using Intel's fancy warranty.

I've seem to hit my wall overclocking wise, at 4.8GHz (on air) using 1.36v and a few DIGI+ tweaks.
5.0 would require a good deal of voltage and since I'm on air cooling, that won't happen. smile.gif

I'm getting 13.81pts in Cinebench 11.5 (64bit) so I'm more than happy with where I am though. thumb.gif

You main issue with be volts in all honesty... for 24/7 I'd highly suggest keeping it under 1.40v. And depends a lot on your cooling an mobo. Many mobos will start to throttle your OC, so you have to have active cooling of some sort.

I honestly rarely see the benefit of 5.0+ over 4.8GHz.
