I7 920 overclocking help!!!

[xavier1618]

Hey as u can see from my signature everything my new pc is running. I'm new to this forum and to pc modding. i would like to overclock this liquid cooled machine to something u guys think is stable enough for 24/7 use. or if u think it would be better for me to let the pc relax a couple of hours in the night. if u guys need anything else or need me to start getting some monitoring programs let me now. The whole pc is stock right now no OC yet.

4ghz should be real easy without much voltage increase.

I assume you're looking for specific BIOS settings for a decent overclock? If so then give these settings a try for 4.0GHz (w/ both HT and Turbo enabled, and assuming default RAM timings are 9-9-9-24 at DDR3-1600)...

hey guys thanks for the reply. redduc900 are these bios settings specific to the x58 sli le cause i dont want to have extra tabs that i dont know what to do with. i remember on my bios there was a tab named Dummy O.C. so i will search the bios and check all the tabs out and repost later to see anything extra.

hey redduc900 there were many more tabs then i thought, i will try with what you gave me and see how it goes if anything thanks now for the help.

Yes, the BIOS settings I posted are specific to the LE. I thought you were only interested in "overclocking" related BIOS options, not settings for every option in your BIOS. And there's no way any of us can guarantee 24/7 stability of your system, or anybody elses for that matter w/ the settings we provide. The settings I provided for you are ballpark figures, so I leave it up to you to tweak the settings if necessary to provide stability. Your system components are close to top of the line, but irregardless... I still can't guarantee you stability at 4.0GHz for 24/7 operation, as there are too many variables to consider.

The first thing you should do, as should anybody, is backup or image your existing install prior to altering or flashing the BIOS. You should also run Memtest86+ to check for RAM stability before attempting to boot into Windows for the first time after making any overclocking related changes.

Welcome to OC Forums

Like redduc said, you have pretty good components, so your chances of being able to achieve 4.0Ghz are fairly good. I am fairly new to the i7 game, but if you could list your BIOS settings, it would help give us an idea on where to steer you to a hopefully successful overclock. The main settings you need to worry about are your cpu's core voltage, your ram voltage and timings, your FSB (usually called BClck or something like that), your CPU multiplier (usually 19-20x), and your chipset's voltage. From your signature, it looks like you have a pretty good idea on your RAM timings and speed. LEt us know of you need anymore help!

You shoud be able to reach 3.6 without any vcore change. I have EX58-UD3R and i only need 1.72500 to go up to 3.8 with ht and boost enabled
