ASUS Maximus II Formula - new P45 king?

[cstkl1]

Forget it......


I must make a CMOS Reset when I use 400, the Board switch on and off, but I can not go into the BIOS.....

y??
how u think i was running at 400fsb 1066mhz??

strap 400 is usable on p45's more than x38's/x48's since the tRD is now same as strap 333...

on x38's/x48's it takes a tRD hit..

hmm i've been looking at all u guys on ure settings...
why arent u all adjusting ure gtl on 45nm proc.. u should.. if not ure just overvolting ure proc..

calculation is simple

this is for 500fsb on crossfire...
vtt 1.2v nb 1.2v
gtl 0/2 = 1.2v x 0.635 - leave this at auto
gtl 1/3 = 1.2v x0.667 ( too high)

to change
1.2v x 0.667 + Y= 1.2v x 0.63
Y = 1.2v(0.63-0.667)
= -0.044
so u should change gtl 1/3 to -45vm

for 400fsb on crossfire
vtt 1.12v nb 1.12v
1.12v x 0.667 + Y = 1.2v x 0.63
Y = 1.12v( 0.63-0.667)
= - 0.04144

so u should change gtl 1/3 to either -40vm or -45nm depending on ure voltage flux on load..

have fun maximus 2 users

for 65nm
u should run 0.667v for gtl 0/2..
so u should + vm on it..

u will find this board much more stable.. and less voltage on vcore if u do this and make sure ure vtt is = or more than ure nb..

Can you give an example for 65nm cpu, in your equations above you have their volts as the same, so no reference for me to figure which goes where.

given VTT = 1.35, vnb = 1.30

ok say ure using vtt 1.35v

so adjustment for gtl 1/4 is null

therefore u need to adjust gtl 0/3

so how much easy
1.35v x 0.667 = 1.35v x 0.635 + Y
Y= 1.35v( 0.667-0.635)
Y=0.0432v
= 43.2mv

i usually roundup.. so u should +45vm on gtl 0/2

havent really tested a 65nm quaddies on p45's but from experience in the past with other boards.. 65nm works best on gtl 0.667/0.67

Thanks for info, I figured it out

What about for NB GTL?
would I vtt, and .667, board default appears .64?

1.30 (.667) = 1.3(.64) + y
y = .0351
