Hi there,
Read many forums about my issue but not really struck gold as yet :-(
I previously had an ASUS striker Extreme II and got a super overclock.
I got this board to 4Ghz (444 x 9) with the RAM running at 1857Mhz (8-8-8-22) stable on memtest / Prime95 and 3dmark06.
But sadly it was a dodgy board and kept corrupting my O/S (on even stock settings).
So I RMA'd it and didn't want all the pain to come back so I got an an maximus extreme.
Now with this board I can get the E8400 CPU stable at FSB = 470 with a multiplier of 8.5x (4Ghz), which is great. But in this case I have to run the RAM with 8:5 dividers (FSB strap 333Mhz), which is pointless.
I cannot get the RAM stable (OCZ 2x2GB 1600 EB 7-7-7-22) above a FSB of 433Mhz.
Amongst other settings I've tried upping the RAM voltage but it does not appear to be helping. One thing I do is is a +0.08V offset on the RAM (i.e. BIOS = 1.86v and in O/S = 1.94V).
Any ideas on how to move forward here with the same RAM? What performance hit would I take from running with different dividers (like 8:5 for example).
Thank you!
Mark
