Those of you with OcUK OEM 2700K Official OC Results thread!!

It very annoying to get a best mobo which it very expensive one (like over £300 pound) to get a good clocker mobo but to be honest I stick with my 4.8GHz and your at 4.7GHz can't complaint anyway!

Why waste money on great mobo for 5GHz, it pointless really. I just save up for ivybridge and get a best board with new cpu next year. :)
 
As tempting as it is to upgrade, I think I'm very happy with my 2500k @ 4.7Ghz 1.336v idle 1.312v under load.

I had it stable at 4.8Ghz but the temps were getting too much for my Lanboy air + Arctic Freezer Pro Rev2. I think with what I have already, I could join the 5Ghz club to.. thinking of a H80 tbh maybe even a H100.

Thats a good CPU you have there, my 2500K I can get to 4.6GHz 1.024v idle, 1.336v under load using power saving features, I have also had mine stable at 4.8Ghz at around 1.42v using manual voltage.

It's tempting to get one of these 2700K but considering I only paid £140 in June for my 2500K, their just doesn't seem enough reason too.

Hurry up Ivybridge, will definitly pre-order one of those. :D
 
Just noticed a rather wierd thing... if I leave IBT on 'Auto' for number of threads my score goes up to 124gflops (from 110gflops when manually set to 8). :confused:
 
setting to 8 is the proper way to stress test a 2600k or 2700k. It actually hits the hyperthreading the way it should. Auto I think only uses hyperthreading when it feels like it ;)
 
setting to 8 might not be the best way. Since there's 2 threads running per core, it will have to task switch during the times it can't run both threads using hyperthreading, which will slow down computation and stress less.

Can someone post GFlops and temps with 4 and 8 threads on a 26/2700K to confirm this?

I allways set it to run with 8 threads which loads @100%, if i use auto it only seems to load at between 57-60%.
 
hi guys, is it likely the ivybridge is to be released march-april 2012 and no earlier ???

p.s
I'm not a newbie in here, I had to reregister as I forgot my username and password, dont ask why, I was just away for a while, lol, but I read the forums with great interest, thinking of buying a 2700k setup right now, thats why I'm asking about the Ivy.

thanks :)
 
I think this is an Asus bios issue,

Maximus extreme iv with 2600k will via its own software overclock by 35% but when I installed the 2700k its max overclock via software was 13%,

Anyone else done this

front what I've read the h100 isn't really that much better than the h80 temps wise, if you can find it in stock(read from a competitor) get the silverarrow.
 
so how can the thermalright silver arrow air cooler possibly be better than a corsair H100 with multiple fans in a big case, can someone explain this please ?

I have always been in favour of air cooling until now, not after reading lots on the latest liquid coolers like the H100 etc, I now think it has got to be logic that its cooler to use liquid than air on the cpu.

If someone can explain otherwise then please tell me as I dont want to be wasting my money.

Thanks :)
 
Lets take the silver arrow as an example.

Massive heat pipes that use liquid (of a form) to move heat from the CPU block to the fin surface area. - The same as the H100.

Large fin surface area to transfer heat to air - The same as the H100.

Twin fans to move air through fins - The same as the H100.


Essentially you have the same setup just one relies on passive heat pipes and one relies on an active pump.

The silver arrow has two fin arrays that take an 140mm fan. So that gives you approx 240mm of fin surface area to distribute heat just the same as the H100 120 x 2 radiator.

The similarities are all there if you really think about it and it is hardly surprising that they perform very close to one another.

The one thing the H100 has that the silver arrow doesn't is a length of tubing so that you can choose where you take the air and send it too that you use to cool through the rad by positioning the rad in different places.

Remember though the H100 has a pump and these dump heat in to the coolant as much as 3-4°c (depends on the pump)

Hope that helps?
 
Dont also forget that Silver Arrow is huge and will limit your Ram choice while H100 or any All in one pseudo WC kits are usually not anywhere as space occupying as huge coolers.
Having said that you also need space to mount the double rad of the H100.
With SA you cant upgrade anything while H100 gives you a possibility of mounting it in push/pull config if you have enough space in your case as the rad is reasonably thin compared to proper WC rads (there are a few exceptions though).

One can just as easily change the fan combinations on the silver arrow mate. Push pull or four fans even!
 
Sorry, didnt make myself clear - with enough space you can have H100 with four fans not just two.
Not trying to convince anyone to H100 or to SA but simply trying to point out things others omitted :)
 
Right then fellas - I've been doing some more experimenting since going back to watercooling. ONLY my cpu is watercooled by a thermochill 120.3 with 3 x scythe GT's. Bearing that in mind - cooling is not an issue.

I find it VERY difficult to keep temps under 80Degrees C, so messed around a bit. Looks like anything above 4.8Ghz does NOT like my memory running at 1600Mhz. This is because my memory needs 1.65volts to keep it at 1600Mhz and above. Its actually rated stock speeds of 1.65v @ 1866 - but setting it at 1866 won't let me boot anything above 4.6Ghz.

SOOOOO - Be warned - If you want super high overclocks on your 2700K (4.8+)- make sure your using 1.5v memory. Looks like I'm going to have to settle for 4.8Ghz with 1600Mhz memory, otherwise I'd need to downclock RAM to 1333 (1.5v) to keep 5Ghz :(
