Reasonably high, but running small FFTs for max heat and not many things you do on a PC stress it like this fake testing.

with my Q6600 I tend to find small-prime similar temps to video encoding

but both not as hot as IBT

Speed: 4.321
Voltage: 1.182 (stock)
BLCK: 100.5
Multiplier: 43
Corsair H100 (medium)
Prime95 max temps: 62-60-61-65

Not stable at 4.4 at stock volts. Blue screened after a few minutes of Prime95. However, managed over 20 mins of Prime95 at 4.3 on stock volts, which IMO is pretty good. Should be stable at 4.2 on stock volts which is a nice free boost.

Do your temps change at all if you put the H100 to max?

the_director · 2 May 2012 at 20:06

Not tried it, it is stupidly loud on full! Others have said it only drops temps by a couple of degrees.

Ollie1132 · 2 May 2012 at 20:10

Yeah Ive seen. Im hoping my Alpenfohn K2 does a better job tbh xD

could some kind soul point me in the right direction of how to overclock my ivy 3770k using an Asus p8z77 vpro ?
thanks in advance

I've had my H100 to max and I thought the case was about to take off!

It only lowered my temps by about 2c though.

If you read this it's quite straight forward.

There seems to be like a noticable difference in chips.

Some won't go over 4.3-4.4 and some easily reach 4.6-4.7? :O

Ollie1132 · 2 May 2012 at 20:21

Yeah apparently so. I hope mine will be one that easily goes up to 4.6~... Id hate to have to DSR it :/

You know a 4.6Ghz OC on a IB is pretty much the same as a 4.9Ghz on a SB right..?

Theres 3-5% clock for clock between SB and IB, so no.

Off by like 0.055Ghz..

reddev85 · 2 May 2012 at 20:37

Mines still stable at about 4.75Ghz (47 x 100.9) at 1.325v. Had to do a bit of tweaking with LLC to get it stable at that vcore - noticed a bit of vdroop that was causing instability. Temperatures are hovering around 74-76c using Small FFTs.

48x requires a large jump in voltage - and the temps soar with it - so this is as far as I go for everyday use.

I don't know why, but when the BCLK is set to auto, it always goes to 100.9. Even when I manually set it to 100, it makes no difference - but it's stable, so 0.9Mhz isn't really anything to shout about.

5% on top of 4.6

= 4.83

Ollie1132 · 2 May 2012 at 20:53

yeah so a 4.4Ghz IB is basically a 4.6~Ghz on Sb... just about anyway...

Buckster · 2 May 2012 at 20:56

yeah

4.62

Ollie1132 · 2 May 2012 at 20:57

I can't wait to have my IB rig running tommorow... my friends tried to tell me not to OC... was like pft... as if.

jwsg · 2 May 2012 at 20:59

...and people hoping for 5Ghz would only be getting a benchmark 10% greater than those happy with 4.5 on stock, yet those with 3770K have paid 50% more than those of us with 3570K.
