i have rev2.0 modbo with 2.1 bios, c2d e4300, 2x1gb patriot pdc22g6400elk. my problem is that the memory stars like 1024mb if fsb are set higher than 250. if i lower the fsb everything starts ok (2gb dual). where is my mistake? memory timing 5 5 5 12. flex mode doesn't helps.
Try manually setting the memory timings in bios, also some people have reported success putting DDR2 voltage to Low.
it doesnt work unfortunately. voltage set low, timings set manual to 5 5 5 12(not work if fsb >250)), i was try to set them to 4 4 4 8 and... not work if fsb are set >250)
I think the problem is more related to going over 250fsb, most here can't get that high without running into major problems.
The best way You can get more fsb from your processor is to do the BSEL mod so that Your mobo thinks it is a 266fsb chip, if You are interested just google e4300 bsel and You will find plenty of links.
You would also have to do a Voltage pin mod on the cpu, or alternatively a vcore mod on the motherboard as your e4300 won't boot at 266fsb on its default voltage.
