Bad crop i know but too tired to sort :)

Please update mine :)

Edit: Just realised how high i got with the voltage...eek!!

WOW some really nice overclocks posted guys. 5.3GHz is really nothing to be sneezed at from our two newest members of the 5GHz club.

And TopDog nice to see you sharing with us. You still hold the world record for PCMark05?

Guys TopDog is one of the elite bencher's in the world. OCUK is pulling some real overclocking posting talent I see.

Thanks to both of you for your comments, I just submitted another PCMark05 score yesterday of 40800 which is a World Record for a four core cpu.
 
Woohoo.... membership acknowledged :)

I'm hoping to get a sub 7sec result before too long. My watercooling setup was spec'd around being quiet for night time gaming about 5 year ago, bit have changed but rad/fan combo is the same.

At the moment I seem to be getting 1 or 2 runs in then I can't get another run to work at same settings - not sure it loop is heating up too much. Going to investigate if block mount is good and if better fans might help.

Failing that, big bucket, two barbs, 5L of water and a big stash of ice :)
 
Win7 is the easist OS to boot into.

XP is not so simple but SandyBridge does not work like other CPU's; previously there was a range of uncertainty with a CPU overclock. What I mean by that is you would maybe get into OS and take a CPU-z shot and that would be that. Drop a few MHz (20 - 50) and you might be able to run Super Pi. Drop another 150MHz and you could do 32Mil. SB does not work like that. 99% of the time your highest overclock. The wall if you like will also be your stable overclock for a benchmark. If you can run 1mil in Vista or Win7 you will boot into OS in XP.
 
Been messing with this Cpu a bit and think I'm hitting a wall around 5420 mhz :(
Locks up during windows boot @ 55x & 56x multi, tried up to 1.55 vcore but no go.

Anyways here's an updated run :

That is very very good Bos - what motherboard are you on.

If you want to up your BCLK and you happen to have a Giagbyte board you may need to go into BIOS and change the BCLK setting to 1010 reset (F10 and boot into BIOS once more) and up it to 1020 and reset and up it to 1030 and so on and so on. That is the only way to boot into OS with a high BCLK on some Gigabyte boards. You have a very good chip if that vCore is the same under load.

I'm still on a B2 P8P67 Pro, waiting to see what the Z68's are like before I decide to get it replaced/refunded.
It is a good Cpu - runs 100% Prime/IBT/LinX stable for hours @5ghz with only 1.32v core but anywhere near 5420 and it craps out.

I did that last run at 54x 100.2 fine but as soon as I upped the BCLK to 100.3 it locked up even tried with a bit more voltage.
