***Official Ivybridge Overclock Thread***

although temps go up both with clock speed and volts ....

so higher volts on same core speed would be a bit hotter - but not as hot as with a bump in clocks too :)
 
I dont know how intelligent Windows is to allocate to fastest core though ....

I mean for gaming 2 really fast cores - + 2 slower cores would be great
 
Think I might settle for 4.3ghz for 24/7 overclock I can get it stable at 1.164v and the temps never go over 75c. The voltage jumps required to go up 100mhz in the higher clocks seems odd though.

It does. For me to go from 4.3Ghz to 4.5Ghz required a voltage jump of 0.1V to go to 4.7Ghz I think I would need at least another 0.13V~ at least the jumps aren't as great as SB.
 
so think i'm settling for this :) tried volts a bit lower but they would return WHEA errors... I no like errors :( .....but it did tickle me when i noticed it was 1.21 gigaflops xD

oh yea... fyi.. the ambient temp in my living room is 27 degrees atm!!!!

Well for me I need more than 1.225v to get 4.4 stable and I didn't even bother with 4.5 I was getting too high temps before nearing anywhere close to stability.

Damn I heard the 3570ks require a bit more voltage but a lot of people I've seen with them only had to have about 1.18V to be 4.4Ghz stable.
 
Been running my 3570k at 4.5GHz using 1.185v for a couple of days now after running various Burn Test tests. Don't seem to be getting any WHEA errors either! Doubt I'll take it any further as I don't think there would be much point as temps would start becoming an issue for unnoticeable gains. Need to run prime really but I fear temps would get towards 90 degrees with the current weather!

Wondering if I should put another fan on my H60 to bring temps down a little bit.

:eek: I'm at 4.6 with identical temps to you.....but only 1.05 Gflops! I'm not being throttled (Max temps 80/88/84/85) and I pass 10 iterations using the same settings as you - but somehow I'm slower :(
 
4thAttemp - its prob as results are lower with Hyperthreading off ...

I do like my 3770k now I have to admit ...

it seems really good at multi-tasking - can do video encoding + other things at same time far better than on previous system

was just playing DCS A10/DCS World whilst doing a handbrake encode in background :) game was still smooth - loading times just took longer

ahah unfortunate. I wish I had a better chip in all honesty. It's actually pretty decent for voltage... but it's just a hot chip :(

It could be because I'm using the offset rather than a fixed voltage, because it passes all the full load stress tests, but then messes up during games which don't use that much load.

I might try with fixed voltage and see what happens.
