Windows 7: i7 2600K @ 5Ghz!

i7 2600K @ 5Ghz!

I’m posting this here instead of the sticky ‘Post Your Overclock’ cause I did not run Prime due to the temperatures I was reaching. So I feel this is not a legit OC. But I did run a stable 30min stress test in AIDA64. Being unfamiliar with Intel, reaching 91+ Celsius scared me enough to back out. However with a better cooler I’m confident that this machine can reach 5GHz+. Apart from setting the DRAM frequencies, everything was done within Asus AI Suite 2 that came bundled with the motherboard.

Previous I could not get past 4.73GHz without BSOD but that was with tweaking the BCLK and multiplier together. Keeping the BCLK to default 100MHz I was able to set the multiplier to 48 no problem on default voltages and run stable with high but respectable temps. Increasing the multiplier any more I could boot into Windows but would BSOD under stress with default voltages.
Tweaking the voltages I was able to set the multiplier to 50 and run what I feel is stable but a HOT 5GHz! Here’s my settings based on a Asus P8P67 Deluxe board.

BCLK = 100MHz
Multiplier = 50X
DRAM was set to 1600MHz @ 1.6V
VCore set 1.37V but throttled up to 1.53V
DIGI+ VRM:
Load Line Calibration = Ultra High
CPU Current Capability = Auto
VRM Frequency = 380Khz
Phase Control = Extreme
Duty Control = Extreme

I’m in the market for a new cooler (advice would be appreciated) so stay tuned!

That's pretty amazing. Remember when 4Ghz was the golden "Wow moment".

5Ghz... from a desktop, residential computer, simply amazing.

Has anyone else found that the software that comes with motherboards that allows you to overclock, almost always jumps the voltage too high, and thus increases the temperatures abnormally, compared to manually overclocking?

I'm guessing that it's "safety" on their part, almost guaranteeing a stable OC, but seems a bit overkill. You could probably get some lower temps by manually copying the settings from the software (Into the BIOS) and then slowly creeping up the voltage.

This is exactly why overclockers hate overclocking programs...

The newer Turbo V software that came with the board is a lot better than previous versions. Yes if you click on the “Auto Overclock” button it sets everything very high. But using that function I could not get past 4.7GHz. To reach that magic 5GHz I manually changed the voltages along with various other settings using the Turbo V software. You can make the changes within the software, and if you didn’t crash (or BSOD) right away it allowed you to stress test without having to reboot. I found it very helpful.

I’m currently running at 4.8Ghz 24/7 with very respectable temps. Haven’t had the time to toy around at 5GHz but will do once I pick up a better cooler.

You better turn this Sandy Bridge back in and wait until they have fixed it.

Hmm, how about a Corsair H70? or if you don't want watercooling, you could use a Noctua NH-D14 those would be my #1 choices

It is the chip for the SATAII controllers that is bad, not the CPU.

This. i've seen people confused about that issue, as long as you keep your devices away from the SATA II ports, you're fine, plus...

Most end-users don't have more than 4 SATA devices (4 being the SATA III ports on the motherboard) so they wouldn't be that much compromised.

I have 2 HDDs and 2 DVD-Drives (and i only use one, i'm thinking about removing it) i mean, i'd rather have all my HDDs (in case that some users have 4) on the SATA III ports and leave the DVD-Drive(s) on the SATA II, since it's not used often
