This is easy to fix by lowering the OC and resetting my main HD as the primary boot device, but I'm trying to push it further and can't.

voltage = 1.45 vcore +.4 memory +.1 MCH & FSB

Any ideas?

Did you try raising your voltage another notch?

[fletcherfunk]

My vcore Voltage? Shouldn't 1.45 be plenty for up to 3.6? I guess I'll try putting that to 1.475 and seeing if it helps...

[fletcherfunk]

Tried raising both the vcore then the ddr voltage... I still get the same error upon reboot...fails to detect my hd when I raise the fsb any higher. !

Yep, it has been locked at 100.

sorry for the double post, but this appeared above your last post for some reason:

Yeah, don't do it. You won't be able to get near as much stability in an OC if you do. I believe this is because more juice is required by running 4 sticks instead of two, so actual voltage to the memory drops, thus reducing what it can be OC'd to. Add that to the fact that many boards just have bugs in general with running 4 sticks, and it's just really not a good idea.

I updated my bios and that fixed the ntldr problem! Now I'm at:
3.6 (400x9) / 800mhz ddr
vcore 1.45
ddr voltage +.3
fsb and mch +.1

Idling at 30... going to throw some tests at it and crank more if I can!

W00t! Awesome! Good to see you found a solution.

I'm happy to report that I'm Prime95 stable at 3.6 GHz (450 x 8) with a BIOS setting of 1.46875 vcore (1.424 in CPU-z). 54C load, 25C idle.

Memory (PC2 6400) is synced so it's overclocked to 900 MHz at 2.2 volts (within it's rated voltage). Timings are 5-6-6-21 2T so I'm goign to work on getting these tightened up a little.

FSB and MCH haven't been raised. I figure I could go further with this, but I'm satisfied with 3.6 GHz, which was my target (although I may try to get it higher later...)

I seem to be stuck at 2.66ghz. Currently i set the fbs to 333 mutliplier is 8, ram mutiplier is 2.0, volt 1.3625 , ram set to 4-4-4-12, ram volt +.4 If i go any higher then 333 the system will just double post and it sets everything back to stock. I've tried doing +.2 for fbs volt and mch +.1. what I want to end up with is 2.8ghz (7 * 400) so i can get my ram running at 800ghz. I tried the 7*400 and system double posts and resets as well.

Did you manually set your PCI Express Frequency to 100 MHz?

Also, try stepping up your vcore a notch or two, and maybe set your RAM settings to Auto. Once you get your OC where you want it, then try to tighten the timings back down again.
