i7 920 OC Help

post #1 of 16
Thread Starter 
Here's my system:

I7 920 D0 stepping 42c PRIME @2.66 1.285v
Corsair H60 2x Blademaster Push-Pull
6GB Corsair Dominator 1866 9-9-9-24 1.65v
MSI GTX 470
Corsair 750TX v2
EVGA X58 SLI LE

Ok, when I start to OC, my system refuses to post after 150mhz bclk, regardless of voltage.

Any ideas?

Also, if anyone can tell me how to disable the auto repair in the win 8 rc, I would greatly appreciate it.

most of the first generation i7's don't like running with multiplers of even numbers like 20, 22,24 when overclocked

try using 21 as a multiplier and a number that shouldnt be too tough like 175bclk

put you're vcore at around 1.33 until you find a stable mutlipler and bclk you want

(my i7 950 d0 runs 1.35vcore for 4.2ghz)

Will try as soon as Windows decides to cooperate.

Okay, sorry I don't have much of a clue with windows 8.

take a look at this thread while you're at it

http://www.overclock.net/t/538439/guide-to-overclocking-the-core-i7-920-or-930-to-4-0ghz

I recommend disabling everything in terms of turbo mode, all the power saving states etc and turn off hyper threading until you get you're first OC stable.

Sounds like you need to lock your ram from going up when you push the bclk. Unless you have something that isn't liking the higher blck, perhaps a sound card or something along those lines? Thanks

JAM3S121, I have read through that article, all the power saving features were disabled and turbo is disabled

I got windows 8 to like me again, I keep forgetting to change my SATA ports from IDE to AHCI after I reset my BIOS.

KILLER_K, I nock my multi for my ram down a notch so it doesn't run out of spec, for now anyway. The only card I have in my system is the GTX 470.

No dice on the x19 multi BTW and it wont let me set it to x21.

Am I doing something wrong?

Let's take a different approach. Start off at 100fsb and pick the 20 or 21 multi. Start moving the bclk up a little a time until it doesn't boot. Then start adding a little move cpu voltage. See if it will then boot. Once you find your max bclk then you can go from there. Thanks
