I has Sandybridge - Excellent service OCUK

is there a multi wall on these? or was that just on the intel boards or something? i believe in the intel boards people used the turbo multi to overclock but you are actually doing it the other way and setting the normal multi?

some talk about this "wall" and i never fully understood and what i did understand was that you could put in 46 multi fine but once you try say 48 or 49 it wont post no matter how many volts or tweaks u do to it.

ps is the msi mobo better than the asus p8p67 pro? also what would be the max 24/7 volts for these? would 1.4 be fine 24/7 for a few years?

You can disable turbo and speedstep and leave it running at its max, or enable them and let it downclock itself.

Will UEFI be easier to update than the already existing BIOS system of updating?

Yes, boot into UEFI then select live update, it then does it all for you!

Set multiplier to 48

Disabled turbo boost and speedstep

Set vcore to 1.42

Would these a be a big leap forward from a Q6600? And also justify a £2/300 upgrade?

what temperature where you getting please?

I've upgraded from a C2Q Q9400 running at 3.6, and this is a BIG upgrade, this defintely feels next gen

Good stuff!

32c idle with 50% cpu fan

77c 100% cpu 75% fan - prime 95 small fft after 15mins

I think i'm going to leave this chip at 4.5ghz as that seems good, with a vcore less than 1.28v

I think I could do 5ghz no problem tbh, but if someone wants to pay me the money to find out

Go right ahead, I don't plan on nuking this just yet, hey, it's not even official yet lol

are you running 1.4+ through a 32nm cpu?

Thats brilliant, sod the 5ghz overclocks im more excited about the new UEFI. Its about time you can just click update on the bios and it does it for you

Im not gonna upgrade my rig till 2014 i promised myself this and im gonna see if i can do it :rolleyes:

Ran 1.4v to get to 4.8ghz, now back at 1.28v for 4502mhz

I've adjusted the ring bus to 105 and got it to 4502, and it seems way way quicker, which shows on the cinebench benchmark 8.81 as opposed to earlier 8.36 @ 4490mhz

Thats going some now Dave, good work.

gary996 · 7 Jan 2011 at 21:02

impresive results there

dave_beast · 7 Jan 2011 at 21:05

4.8 ghz at 1.39v (Set vcore at 1.38 in UEFI)

wow thats really great to see, got my 2500k in the post, along with a P8P67 PRO and 4gb of corsair.
Probably wont go as high as you have dave, not just yet anyway. my goal is ~4.2 on as little volts as possible.

Should do 4.2 on stock volts :cool:

tried bit tech settings?

We overclocked the i5-2500K by first setting the Load-Line Calibration of the Asus P8P67 to Extreme. We then set the Base Clock to 104.7MHz and the CPU multiplier to 47x for an overall frequency of 4.92GHz. To make this stable, we set the CPU voltage to 1.35V, the CPU PLL to 1.9V, the VCCSA to 1.1V and the VCCIO to 1.106V. See How to Overclock an LGA1155 CPU for more details on how we overclocked all the CPUs.

you could mimic some of thier settings on your mobo and use 105x48 at 1.35v?

Glad I waited to see what SandyBridge was like...and it looks good!
