I have tested my 4Gb ram up to 472Fsb, and I just installed some brand new (still in packet from old RMA) 2Gb crucial ballistix DDR2 6400.
I know this can do like ~1200Mhz but dies within months (I hear they have different lower voltage ballistix now), but I don't even need 1066 (533Mhz) from it.
I said that cause I believe the ram is not the problem. Since from my screenshots I am about 1% o/c on the CPU thats not the source of instability. I'm looking at the motherboard.
It makes the PC freeze if I run right mark memory analyser for a while, and maybe a couple of videos and azureus in background. Its fine for games. Has passed OCCT stress test.
What I want to know is are there any settings combination that I should try to make it completely stable. I'd like to overclock my CPU but its a bit redundant if my motherboard is unstable at relatively modest FSB speeds.
I think that vMCH (north bridge) and vFSB are responsible for mobo stability, but I think vFSB maybe to do with that reference voltage that P45 boards have, so its not a case of up it till it works but finding the sweet spot.
