Okay, so it looks as if users are clocking their CPU's higher on lower volts for this motherboard these days... Is it a newer revision motherboard or the new bios being that it's on the same CPU's as it was before? Sorry, I'm not up to date on this topic as I used to be..
Hey Mastiffman! Glad you're still able to post on this thread. How is your almost 1yr old? (If I recall correctly
I gotta agree that the newer chips are just more likely to get 4ghz performance on lower volts because of the "maturing" of the chips. I'm sure they didn't make a new revision because the changes weren't as drastic as C2 going to C3.

Corsair H50 Cpu Cooler,
My questions are do you think I will be able to achieve 4ghz with the above sepcs? Also I am currently running BIOS Version1.A is it worth upgrading the new version?
I would be grateful for any advice you can offer.
You should be able to, though every chip is different, so there's no guarantee to 4ghz. First update to 1.G, lots of people are getting good results with that BIOS, myself included.
To get to 4ghz: I would recommend you put your northbridge and RAM speeds back to stock and push your CPU multiplier to 20x. Put the CPU voltage (3rd voltage setting, not the 1st setting called CPU Voltage VDD) to 1.4v-1.45v and test it out with LinX or IntelBurnTest with maximum memory. Run 10-20 runs and if it passes, it should be stable. Go with as low a voltage as you can (even below 1.4v if stable), so it will take a few hours of testing, even more if it doesn't get stable(keep adding voltage one click at a time up to 1.5v if it's not stable).
Once you find your stable voltage for your cpu, you can go increase your northbridge speed to 2600-2800mhz(13x-14x multiplier) using 1.25v-1.35v on your CPU-NB voltage (4th voltage setting). Again test it out with stress programs and if it is stable at your lowest voltage then you should be golden.
It is up to you to overclock your RAM, though there really isn't any significant benefits from that. I haven't seen any real world performance increases from 1333mhz Cas6 to 1752mhz Cas7, so it's really up to you.
Good luck and if you need help in anything else just come back here!
Edit: BTW, I had trouble getting 4ghz stable with 1.44v when I had my NB at 2000mhz 1.2v, but putting it to 2800mhz with 1.28v let me get it stable. Though I wouldn't recommend overclocking both at once, since you won't know which is unstable. Just something to take note of.

Yes, mine is at 4ghz with 1.44v right now. You have to make sure all cores are not faulty before you overclock though, so if you hit a wall at overclocking, make sure you turn off one core and test with a higher overclock. If it is successful, then you know that core you turned off is slightly faulty, if not successful, then try a different core.

When completely stable I am within .01 Gflops of each other except for some freak ones that are due to other tasks that maybe going in the back. (when running max) when just doing 17000 I might be .2 from each other.
Is it possible to have varying numbers since it's two different programs? I did notice that LinX has numbers closer to one another, though IBT has slightly less precise numbers, about .2+/-.Edited by Kokin - 1/30/11 at 12:01am
