On LGA 775 every FSB MHz counts and 50MHz FSB is A LOT..

And your RAM would run at 1000MHz and with 500MHz FSB it would give you almost 9GB/s READ bandwidth..(you can check RAM bandwidth with Aida or Everest program)..

CHEERS..
ok, well I don't understand why 500x7 is better performance than 450x8, so i'll just take your word for it. I tried those extra settings you suggested and it still won't POST any higher than 502x7

Edit: since you seem to know something about this motherboard aswell (?), maybe you know why everytime it boots up it tells me no hard drive found, and then proceeds to boot into windows fine anyway? I have the OS HDD in SATA slot #1 too.

Try with :

CPU multi= 6x (to avoid being hold back by Vcore and you`ll do this for FSB testing only to see if ou hit FSB wall of CPU)

PCIE freq = 103
STRAP=333
And to manually enter timings for RAM..

You can see what timings are set by BIOS @ 500MHz FSB when they are on AUTO (greyed out three rows of them) so enter them manually,enter higher FSB 510 and save/reboot..

Also set manually RAM voltage required for 1066MHz..

If that doesn`t help then it`s your CPU`s FSB wall and there`s little you can do about it..

Still test 500x7 vs 450x8 and you`ll see what I`m talking about..

CHEERS..

ok, thanks for the help.

let's say I want to leave it at 502x7 and just go with that, should I change any of those settings back that you told me to change before or leave everything as it is? the voltages etc and that performance thing?

Plug your HDD into RED SATA ports (not orange) as those are using native ICH10R SATA controler and the others use Marvell controler that initiate a bit later on POST..

If that`s not the issue then I don`t know what could be..

If it works then leave everything as it is..

Might wanna to roll back to 1.36vNB as I don`t think that 1.40V vNB has done anything for your OC..

If 1.36V vNB gives you problems then upp it again to 1.40V..

Everything else is OK..

CHEERS..

alright thanks. and yeah the HDD's are in the right ports.
seems fine at 1.36vNB too

when I look at system info in Win7 (right-clicking My Computer > properties) it says the clock speed is 4.02ghz, but cpuz etc all report 3.5, any idea why? just curious.
