Live MB OC Report :: ASUS Rampage Extreme

Hi guys,

My mobo can do 620MHz FSB and my CPU 4670MHz on air.

I was trying to load the settings below:

FSB 530 X 6 Multi =3180MHz
Strap 400, Ram 1060MHz
Ai Clock Twister: Light,
PL10
CPU PLL: 1.55V
Termination: 1.41V
North Bridge:1.63V

But the mobo wont boot no matter what i try or how much voltage i give as long i have strap 400.
The only way to make it boot with these settings is to set the strap at 333,266...

Any one else notice this problem?
How is it possible not to be able to boot with so low settings when the system has been tested at a lot higher speeds?

My system:
Rampage Extreme
E8500
2 X1GB CSX Diablo 2000MHz
GeForce 8800GTX
Bios version 0301

Strap 400 is slightly broken when @ higher HSB IMO...
For my case, 600FSB boot will quickly freeze up using 400Mhz Strap, which will never happen in 333/266 strap.
So I guess for higher FSB you may need to stick on 333 Strap until a patch for BIOS is up in order to fix this problem.
BTW one of the wierd thing is, when high FSB (i.e. 600+ for duals, 450+ for Quads), when attempting to save and exit the BIOS screen will freeze instantly that need hard reboot to make new options to take effect. Anyone experienced this issue?

Thanks for reply.

I thought this is a bios problem...just want to make sure is not only me having this problem.

I get the same problem,some times it freezes in lower FSB is well (500-550MHz).

no its not a bios problem
its a skewing nb/vdimm issue

with that skewing i did and nb voltage and vtt
no issue like that
without skews i get that

very common when u change a setting thats not a ram related changes that requires a shutdown restart.. will hang

thought u guys realize that.. kekeke.. ram nb unstable is the freeze

Seems this is a cool CPU isn't it?
