Mine is with me at work. Stuck here until 6. Will install later but probably spend most of the night sorting put Windows.

My first attempt with a 3770K.

Prime running for around half an hour. (stable)

Malaysia batch number L212B228.

Not sure if I wanna push much further, though if I can get to 4.7Ghz with temps below 80c, id be happy.

 

[MORE SPEED]

Just got my 3570K, I'll get reinstalling and report back later tonight

Should be a tiny bit better than the Celeron in it at the moment.

 

[mattf]

oh mine was malaysia batch L208B084

 

[Doop!]

I just got my 3570k and using IBT at stock speed the max temp was 52 degrees on one of the cores (the other 3 were all a bit lower), that's using a NH-D14 with low noise adapter. It's not going above 50 with Prime95.

Batch is L204B161, Malaysia.

Modest 4.4ghz OC

Hi thought i'd post my results here, only oc'ed to 4.4, with no increase in voltage, temps seem fairly good, plan on going higher in the future but at the moment no real need anyway give me your thoughts thanks.

Thanks for that.... Looking at your results I'm thinking people are panicking solely on realtemp core temps.

Oddly your surface temperature looks very cool at 40C.

Anyone care to comment ?

EDIT: OK with a motherboard temp of 26C - that's even more odd - bordering inaccurate ? :S

Well it shows the same in HW monitor and its reading the cores right so dunno, plus it shows the temps in the bios at around 25 celcius for the mobo. I have got decent airflow in the case plus it isnt the warmest of days, other than that I dont know maybe someone with more technical knowledge can shed some light.

Thank you very much indeed for posting that. Yes it does appear that you have some great cooling in that case - all temps are very low

I usually look at CPUTIN - the delta you've got 33-66 is huge and I think we'll be seeing more of this.

Thanks for posting

No worries mate

Think I've found the thermal limit of this chip.

4.75Ghz stable at 1.345v hovering at around the 78-80c mark, which I'm quite happy with.

However, even one more voltage notch upwards, and I was seeing 96c after one minute of prime.

So, I think I'll leave it here

 

[Doop!]

Just did my first overclock to 4.4ghz, stock volts (4.6 crashed at windows boot at default volts) and the max temp I've hit in Prime is 57. I'm quite happy with that, I was half expecting it to burst into flames

 

[djxput]

4.75Ghz stable at 1.335v hovering at around the 78-80c mark, which I'm quite happy with.

curious - so you are using a corsair h100?; what settings are you running the fans on?

is your fans system quite loud to have your cpu at 1.335v?

 

[Drake22]

mine
5 ghz crashing even with 1.45 vcore
gonna try more later

 

[MonsterMoshi]

Like that you've moved the windows either side of that errrmm... Rather nice female

 

[Subliminal Aura]

Call me old fashioned but can one of you chaps do a super-pi for me ?

No time to install and probably not until the weekend either *weeps*

1.345v actually - edited. I have the H100 on the middle setting. Low just doesn't cut it, and high sounds like a hovercraft.

High setting doesn't even drop the temps dramatically, maybe 1-2c, not worth the noise. Medium is just about right.



1.345v is about all this chip can handle thermally.

Got it stable now at around 4.75Ghz. Have had prime running now for about 2 hours. Max temperature of 80c - and considering the TJmax is 105c, I'm quite happy.

were there any cpu overclocks in that desktop shot ? couldn't see any ...

 

[Buckster]

after comparing some of these clocks and volts (slightly ignoring the temps) - this post by Justintime (hope you don't mind me linking to) below puts in comparison to the seemingly "golden" 2700k

I'd say the Ivys look pretty good in comparision

[Jokester]

Yep, my SB stable clock history is:-
2500K 4.6GHz
2600K 4.6GHz
2700K 4.7GHz

I doubt just how stable a lot of peoples chips are in the 5GHz crowd really are.
