Indeed it was worth of playing. I get bios-posted my rig @ 533MHz Even windows started to loading, ofc it hasn't loaded at all ;]

I used your insane voltages to get this result and most of settings but this time timings was left on auto. My 4GB kit is 1100MHz cl5-5-5-15 by default, so 1066 shouldn't cause instability I guess - am I right? Not sure about tRFC...
Speaking about voltages, what temp do you have on NB? Mine is ~60 right after turning on, checked in PC Health at bios. Isn't that to much for stable work?

Now I'm bit confused. Not sure to replace for the plus version or look more stability with non-plus. For now I've tested 400FSB and it seems to be stable (it wasn't before with 400:800).
I've run for stability test: 1 core SuperPi 32M and the other core single thread of Prime95 large FFTs (max heat & power...) at the same time. If SuperPi done its calculation successful while Prime still runs without an error I'm starting to consider the setting stable :]


One more thing, my rig seems to be strongly undervolted.
Examples:
NB 1.285V @ BIOS => 1.24V @ SmartGuardian
VTT 1.26V @ BIOS => 1.23V @ SmartGuardian
CPU 1.31+V @ BIOS => 1.29V @ SmartGuardian
RAM 1.908V @ BIOS => 1.88V @ SmartGuardian
What can cause this, PSU, mobo itself or something else?
Happy days my friend thats great news

On the subject of insane voltages I took a look at the P45 spec sheet & Intel reckon absolute max should be 1.21v

tRFC makes all the difference when you want every last mhz out of your RAM.

My NB temp is 42~43oC under load with a slow 80mm fan on it.

Stick with your non plus board & spend some time with it I'm sure it'll come good oh & my voltages appear lower in SG too but the few I have measured actually read slightly over on a DMM.

Anybody got the voltage read points for this board ?
