Sandy Bridge i7 & i5 Reviews

[Lucky_n00b]

Yeah. That reinforces what Anand said, 2500K = 52x. So the 2600K is likely to be = 57x.

I got the retail i7-2600K already(D2 stepping), but cannot get it past 4.9Ghz.

4.8Ghz @ 1.35V running IBT about 2-hour (on Corsair H70), motherboard is MSI P67A-GD65.

4.9Ghz need 1.5V, a little unstable, but still can do Vantage CPU test/Wprime 1024Ms easy

5Ghz CANNOT Boot at all...no matter what voltage I applied. Already testing on air , testing a lot of various configuration, for about one week and don't seem to get better result. Still cannot boot @ 5Ghz.

And the most confusing experience, it DOESN'T Scale at ALL with LN2(-130C)...wasted 35L already, no result. Triend the same processor on 4 different motherboard(ASUS,GBT,MSI,Intel), no gain.Not even a 100Mhz increase.Nothing.nada.zip

BLCK Scaled a bit from 104Mhz(air) to 110Mhz(LN2), but clockspeed seems the same (4.9Ghz).

So far, SB = Good for air, nightmare for Xtreme overclocker

Lucky_n00b can you post the voltage step increases from the default freq to the max freq that you reached,please?
....like default V until 4ghz....then 1.3v at 4.2ghz...

This is what I got so far , on MSI board with Thermalright Venomous X:

1.2V (When I load optimized + no Vdroop this is what i get) = 4.3Ghz IBT Stable
1.25V = 4.5Ghz IBT Stable
1.3V = 4.7Ghz IBT STable
1.35V = 4.8Ghz IBT Stable
1.5V = 4.9ghz , no IBT but VantageCPU/Wprime1024/Cinebench R11.5 Stable
5Ghz = No BOOT at all.

Look like my chip at 5.0GHz can't boot anyways to windows but it can reboot from bios to post screen always and for stable like you too about 4.8GHz and benching 4.9GHz for now on Intel mobo but my chip bclk is bad only 102MHz

ps. waiting to try more with other mobo

Yep if not an accident it should be follow the timing

btw. you should type English for here mate
