I can boot all the way into windows at 3.8 3.9 and 4.0... even 4.2 but it only lasts untill i start Prime95, it will either run for a little and freeze. up the vcore and it will keep running and get rounding errors.
i use cpuz, realtemp, HW monitor, everest, Prime95, Intelburn test memtest and SuperPI(i dont really consider this a stability test tho)

3.4 is easy to get to. i can run everythign on Auto and P95 24hrs stable and 20pass IBT max.... but 3.4 just aint enough for me... im power hungry,

I started with really small vcore.. it even boots windows as low as 1.25 @3.8, but again... as soon as you put load onto it the voltage droops hardcore and freezes.

I currently have it at 1.4vcore and im getting rounding errors after 1hr P95.

i think my main problem is the vdroop.. it fluctuates nasty.. for example, im typing @3.8 1.4vcore and Cpuz shows 1.352, start up P95 and its 1.312.

Ram has hardcore heatsync and an aditional ram fan cooler.
NB temp is at 55-59*C under load.

other voltages: 1.35v fsb, 1.65vram, 1.45NB, 1.6 SB

P.S: Ram is 1500% memtest checked


What is your PLL?

Mobo has no PLL option,

options are:

CPU V (1.4)
FSB V (1.35)
Mem V (1.65) -G.skill default
MCH V (1.45) -Northbridge
SPP V (1.6) -Southbridge

Ive just got it at 3.8 with 1.4vcore, passes 20loop High stress on IntelBurn test and can run 6hrs small loop Prime95.
As soon as i run a blend test it will fail within 5 minutes (Rounding error)

im going to try put another .5 on the northbridge tonight to see if thats the holdup.
My Fun one!

No PLL?

Cpu termination voltage? It should have that

EDIT

so only with blend? Try to clock down mem and run blend test again.

FYI i had a Asus Maximus Extreme X38, very expensive board wich ran perfectly with a q6600.

When i got a 9550 the board "sucked", i could not get it passed 3.8ghz. The problem was exactly like yours. Only the blend test failed. As i tried every OC option there is i sold that board For the Asus Maximus Extreme it was a problem, i hope your x48 rampage can handle it.

Have u checked the asus forum? Its very helpfull mostly

BTW -I visited Aalborg back in 1982-great town.
Good luck-Chuck
Thanks.

The fact that you got the overclock stable with command rate 1N is pretty stellar. Nice overclock. 1.25v is pretty low for 3.9 too.
