***The Official Core i7 Overclocking Thread***

[sharpygsxr]

When overclocking lads, Dont just increase the Vcore voltage you need to increase the QPI voltage too, Dont go to much over 1.4V though, It does help in clocking a lot and helps keep them memory speeds high.

locky i never thanked you mate for the stellar work you did on my chip in the bundle, its running rock solid at 3.6 and 3.8 here for me and i couldnt be happier with the rig

I'm running 1.29v in Bios and 1.32 load with my 920 on a RIIE board. Mem voltages are at 1.5 as thats the lowest they will go and that get me a 20 x 183 which becomes 21 x 183 in windows. Load temps with a Noctua and using Linx never exceed 75c

The OCUK OEM chips are Week 43A and most have a VID of 1.2065 volts and clock very well.

How can you check the vid of the i7's ??

Thanks

Got my new i7 rig setup this weekend:



Its using a noctua 1366 which can get up to 74ish if I leave all the threads loaded - the vcore is at 1.2 are temps this high ok an i7 ?

My main reason for posting is: I have had a look around and havent really found much information, but is there little benefit in overclocking the uncore (3408) /QPI link (6135)? - at the moment I have them running as slow as they'll go with the blck set at 170.

sup guys 2nd time overclocking this see what yas think temps etc?

 

[sharpygsxr]

got mine as a bundle from OCUK hered mine with profiles for 3.6 and 3.8 all on a wee akasa nero cooler which is basically the Freezer 7 pro of the i7 range

3.8GHz

 

[Bito]

sharpygsxr....have you tried 4.0Ghz on that yet ?

 

[sharpygsxr]

nah mate i would want a noctuna in there to push to 4ghz and be stable, ive no real interest in hitting 4ghz unless its gonna be fine for everyday use. I would say its capable of it tho as these latest chips from OCUK seem to be belters

 

[Nelly]

Biostar TPower X58

4ghz on Air, 1.39v idle / 1.4v load, HT ON

10 Passes of IntelBurnTest v1.9

Cooling: Thermalright Ultra-120 eXtreme + 1 YATE LOON 120mm - D12SL-12

Hi, My i7 will not pass the prime95 test
I posted a thread in the overclocking part of the forums: http://forums.overclockers.co.uk/showthread.php?t=17995350

When overclocking lads, Dont just increase the Vcore voltage you need to increase the QPI voltage too, Dont go to much over 1.4V though, It does help in clocking a lot and helps keep them memory speeds high.

Does anyone know what the absolute maximum you can safely go to with the QPI voltage? As stated previously, I can overclock my system up to 4.0ghz and not get too hot and pass prime testing and run all day, but the very next morning, the damn thing will not boot correctly and says it has failed due to overclocking or overvolting or words to that effect. I then reset everything and it runs ok again at 3.80 or 4.0ghz all day! I have found that 3.6ghz is the highest that I can run all day and then boot in the morning without the error message on boot up. Thoughts anyone?

Booted at 3.6Ghz.

Settings of 180 FSB and 2.964v on a Biostar x58.
I haven't modified anything else.

Ran Linx 0.5.9 and passed 20 passes without failure.

Temps were - 70, 68, 67, 66

Seems ok.. might try a prime95 run..

As a side note.. my machine sometimes doesn't boot straight away.. just starts, then stops, then starts and resets to defaults. Any ideas on what this could be?

If I leave it for a while it starts ok :S

Happens to me if my settings are unstable. Although sometimes it works after a restart.

Having said that, I have now found it will run for weeks at a time at 3.8ghz without the error. But here is the anomaly, if I change the configuration for some reason, like change the HD boot order or change the bios to boot from the USB stick, it gives me the problem on the next boot (failed for over clock or over voltage), it is almost as though there is a trigger in the BIOS that is causing this random annoying problem.

 

[Chandler_90]

Now at 3.8Ghz stable (I think)

Turned off HT and applied 1.312v vcore.

Temps max out at 64c on all cores.

Passed LinX but failed Intel Burnstep v1.2
Prime runs fine for 2 hours with max temps at the low 60s.

Gonna run it through Vantage and 06 now.

I did get it at 3.9Ghz but would like to feel comfortable that this is safe. 4Ghz BSOD'd even with 1.360v vcore.

Thinking about watercooling now lol!

Here is my d0 920, its 3.8 when turbo kicks in. Love its idle speed

A multi of 2 Is that real? Mine only goes down to 12 (C0, P6T Deluxe).

 

[JeffyB]

Yeah it fluctuates, anything from 2 to 12 in windows is normal, mosty 5 or 7 with occasional 2 and 12.

Put mine together over the weekend, re-flashed SSD's to latest firmware and loaded with Win7 RC 7100. OC'd to 4GHz with RAM at 1910MHz - gonna try to get RAM up to it's full 2000MHz.
Hope I can do this without needing too many extra volts as I think I'm near the limit of air cooling - don't really want to exceed 80 degrees if I can help it. Prime Blend test results:

Whats considered a safe 24/7 full load temp?
