Another thing is the Performance Level.
On both IP35 Pro & Formula is 7 but here seems to be 9 for 450fsb@540 memories on 1:1.2 divider. This is too slow.
I am using latest official 12 bios. Also i have two strange things in bios:
1)I have an 8400 but it gives me 9.5x multi to play (did not set it though to see if it works). It has been reported also by other users in this thread.
2)Also when loading a profile at memory divider setting it shows unknown symbols and set memories to 2200+ Mhz. Very strange bug!!
3)The memory overclocking might have to do with tREF. This is the only option
that according to memset differs in Abit and Asus. I have tested with exact same modules. I think 3120 that set Abit there is too tight according to 16000+ of Asus.
All other settings where same on both mobos.
4)I have set vcore to 1.325. On idle it is 1.33-1.34 and on load 1.30-1.31. CPUz 1.44 though shows 1.5V+!


I have not the time to test further be right back after work.
I will try the 400 fsb /600 Mhz divider to see if it works.
Hey m8,

1. Bios 12 final sucks. Try 12.B08 it's the best for most people (except for QX9650, you need 12.B02 or B03 to get free mult)
2. Interesting what you have to say about TREF. Will try playing around with that option once my two dead IX38 are back from RMA (I couldn't get mem really stable over 1100 either)
3. CPU-Z Voltage works if you set Sensor=OFF in CPUZ.ini - otherwise just use the ĩguru Software or latest Everest Beta
