Currently @ 4.2 GHz (42x100) on my i5-2500K. Gigabyte P67A-UD3 board and Hyper 212 Plus cooler. Seems fine in initial runs of Prime95, but I'm starting an overnight run soon.

Good vcore on that - 1.068V. Can you tell us what the rated voltage range is on that chip? (Of course I could just try to look it up online, I'm lazy)

I'm actually not sure. Tried looking on Intel's site and this was what I got...no VCore info.

http://ark.intel.com/Product.aspx?id=52210

The new version of CPUz (the Sandy Bridge Preview Edition) should be reporting the true VCore, right? My BIOS actually gives something in the 1.2v range, which is very different from 1.068.
 
I don't think CPUZ is reporting voltages right. BIOS says 1.3xx something @ 4.4 GHz on auto, but CPUZ is reporting 1.08 which I find hard to believe. AIDA64 is equally confused reporting 2.9xx which is even more unbelievable.

I'm running the stock cooler at the moment (2500K) but will probably need to pick up the bracket to convert my Noctua tower. Temps are not spectacular which is to be expected.

Viper GTS
 
I'll post some temps tomorrow, I have the 2600k and asus deluxe sitting here. I'll build it when the ram arrives tomorrow.

Does UPS ship on sundays? I just looked in my Gmail box and my tracking number for my 2600K was already sent to me.

Ok, I will post my results so far.

i7 2600 @ 4.0Ghz @ 1.165v. No issues thus far and Prime95/LinX stable @ 55C full load. I will let me Artic Silver set and then set it to 4.2Ghz. I just do not want to go above 60C.

And the non K 2600 can OC to 4.2GHz on all cores. Saved $40 from the K and i get TXT and VT-d.

don't forget to run some games for stability I remembered reading somewhere, the OC holds using linx/prime but fails on games. this new cpu has some peculiarities.

Read that over at Hardocp. Bad Company 2 is an amazing game to test with for stability.
 
Quick question, should Turbo be disabled when overclocking? I have it disabled, but I wonder if anyone is setting custom turbo speeds after OCing (e.g. OC to 4.2, set turbo 1 core to 4.6, 2 core to 4.5, etc).

Why do you recommend against 1.65v RAM?
Click to expand...

from my understanding the memory controller cant be configured from the BIOS anymore, (kinda like you cant change the BLCK) and the stock setting much prefers 1.5V to 1.65V from what i understand the 1.65V will be too much (it will work but will wear the controller down faster)

I might be wrong this is just my understanding

aHHHHHHHHHHHHHH i blame brian at ASUS for being so awesome @ CES.

Total Props to him!

He's convinced me to get SB.

^ thats why.. Motherboard review will be posted today.

I got no cpu tho... lol.. now i need to tell my sponsor ACK i need a 1155!

You win that at the XS party?
 
I'm curious about how the vdroop will behave in this generation. Also, like the last few commenters have mentioned, how many brands of DDR3 memory will behave if they're rated for 1.65V. My guess, based purely on nothing, is that putting 1.65V RAM in there won't matter since the memory controller and chipset will just run it at the recommended settings anyway. All of us will know a lot more in a few weeks.

That's why im recommending 1.5v just in case, besides a decent 1333mhz 4gb kit of 1.5v ram is 40 bucks.
