***Official Ivybridge Overclock Thread***

LOL! Me too!

Though from my little bit of using system since putting in the Seasonic PSU, I am really beginning to think lot of problems were psu.

For example the 7950 I had once clocked to 1125 at 1.18V, but was recently incapable of that, and was not even stable at 1.2V

Currently looking like the 7950 is stable at 1.174V at 1150... not that it matters as 2 x 670 windforce goin g in tomorrow
 
i5 3570K
Gigabyte Z77X-D3H
Xigmatek Prime
62oc (after I realised I forgot to plug front fans back in)
1.16
Stable? Seems so....

Hmm... screenshot a bit small
 
Well, seems 5GHz will take a smidge over 1.3V, but temps AVERAGE 96.75C and hottest core got to 103C :(

17C variance between hottest and coolest cores though?

Damn intel and there cheaping out on thermal contact with IHS!
 
beginning to suspect my motherboard is rather ****, i cant get anything stable over 1.245 vcore,

for example i'm 18hours prime blend stable(12hours small fft) at 4.5ghz at 1.2vcore. i change my voltage to 1.300 in bios(1.288 in windows)with the same settings i get bsod 0x124.

so i drop multi to 40 and rebooted same thing happens... decided to drop my voltage to 1.256 at 4.5ghz... but same thing happens again i get bsod 0x124. back to 1.2vcore and been running prime again for 9hours... :(

also get the same problem if i use 46/47/48 multi with any voltage over 1.245

The core variance is probably more to do with manufacturing the CPU rather than the IHS, at the end of the day as long as the hottest core runs within safe limits at stock then it's fine as far as Intel is concerned.

One day maybe.

Am settling with it at 4.5GHz with around 1.12V under load for now.

Been mucking about with hardware for months now, and just want it up and running.

I'll be surprised it you get it fully stable at that setting. I thought mine was until it failed folding after like 16 hours. I'm up to 1.2+ now and still trying to find stability.

Probably right. Have only done a little IBT loading thus far. Will get Rosetta running again as found that the best stability test for me.
 
Am I correct in thinking if I change voltage from auto to a set number, then it will not vary with load? I have it on auto at the moment for my 3570k with turbo multipliers set to 42 and getting max temp of 70 on core 1. The voltage seems to be staying steady at 1.2560, is this okay, or should I try setting a voltage manually?
