Nice one Gibbo, make me sad that I still got 2600K but overclocked 5GHz at 1.48v since July and no sign of degradation yet

Good chip that one mate.

Well I just ordered an OEM one of these for delivery tomorrow. Please make it a goodun guys

. I'll post up my results from it over the weekend.

bulldog147 · 28 Oct 2011 at 14:09

Good luck Boostjunky - are you purchase the whole new 2700K or upgrade from 2600K ?

Gibbo · 28 Oct 2011 at 14:58

Hi there

As promised some screenshots:-

Prime stable at 5000MHz with 1.41-1.42v

Unstable boot into windows at 5400MHz with 1.55v

Thats air cooled by the way, damn good CPU and thats the first one we've tried.

NathWraith · 28 Oct 2011 at 15:00

Yes lad.

5GHz on air, now that is a epic sight.

Mr Krugga · 28 Oct 2011 at 15:00

5 minutes of prime, pretty impressive.

We need to set these new standards for testing the prime stable overclock now.

bulldog147 · 28 Oct 2011 at 15:08

5 minute isn't stable, need 24 hours!

It happen to me after 37 minutes it crashed to BSD push up vcore, after 12 hours, it crashed to BSD push up vcore and after 24 hours it stable at mine @ 1.48v

Is still running PRIME as we speak, gonna see how long it goes until it bombs, 20 minutes so far.

Easy to do as were 20 mins in on just 1.415v so if it does bomb then a tad more voltage will secure it.

Needless to say these new 2700k CPU's are far better clockers than the current batches of 2500k and 2600k available.

Er, out of curio, whats the highest clock speed you could achieve on the 2700k without effectively destroying it?

is that sarcasm I detect?

gibbo the screen shot is that with the h2flo cooler or some other air cooler?

I have the h2flo bought shortly after release(today only price £37 before they shot up to £45/£50), only got around to fitting it tho finding that when fitting the back plate to the asrock extreme7 mb 3 of the 4 standoffs can be wiggled(the 4th seems to be secure, all 4 have been tightened as equally as possible). oh and should the fan/s be configured to draw air into the case through the radiator or exhaust it?

I've already spent ~£1185 on the upgrade(well the only things I've not bought for this 'upgrade' are the case, hdd, optical drive, os and peripherals(I.e kb/mouse and speakers) as reusing what I have) so not sure I can justify the cost of the i2700k(already have a i2500k which I haven't even started using as only just started putting the pc together). it's actually ~£1755 if you include the dell u2711 monitor which I also got recently

On what cooling and for how long?

Are we talking about a cherry picked ES chip?

Hi there

These are not ES chips.

This is from our large delivery of 2700K OEM chips, all same batch and this is the first we've tested.

Maximum boot into Windows speed is 5600MHz, but its incredibly unstable.

5400MHz is maximum speed where you can get into windows and do basic task.

5000-5200MHz seems to be the prime stable range of our OEM batch with 1.40-1.45v using air cooling (OcUK H2Flo).

bulldog147 · 28 Oct 2011 at 15:29

There is only 5% of those chips can do 5Ghz+ and that is a true fact!

bulldog147 · 28 Oct 2011 at 15:30

What board do you test with Gibbo ?

I don't suppose you noticed I wasn't replying to your post?

I was merely asking Downloadmonster to be more precise in his question.

Thank you for the more specific info on these CPUs anyway.

Are you attempting to be funny?

Or did you just pull out this "fact" out of your ****?

you're above your own recommend max voltages (1.38v) there

axer · 28 Oct 2011 at 15:34

Crikey how are you managing such low temps with that sort of voltage?

Really, well first CPU we grab does it, or maybe we have an incredibly good batch, or the right combination of hardware and knowledge to improve on those odds greatly.
