I am in the same position as 8800's here, my ram is OCZ reaper 1066 (the stuff with the heatpipes and heatsing above it, looks a bit like a prada handbag side on).Originally Posted by 8800's@over
This ram is failry crap and cannot do 1200 (barely does 1120 Overclocked).
This means I am stuck on the 1:1 divider on the 333 strap just like 8800's
I have read on this thread and many others that the best OCs on the P5B DLX are to be had with the 333 strap and the 5:6 divider, hence the need for DDR2 1200 to hit 500fsb.
Its not even easy to go out and by 4gb of DDR2 1200 any more. Everybody nowadays is paying over the odds for rubbish latency DDR3 kit.
What annoys me is that there is no reason for this issue with the P5B DLX - why is the 5:6 divider more stable than the 1:1 divider on the same strap - It must be a bug in the asus bios.
On my old DFI P45 board, the 400 strap was more stable for me, but on the P5B DLX I can't get it to post with this strap - wierd since this strap is actually looser on the Northbridge.
Conventional wisdom on P45 and most other FSB-based intel boards dictates that the 1:1 strap is usually the best for stability, since it is both the lowest and least demanding in terms of northbridge activity.
Well I stand to be corrected here but someone must know why the P5B DLX is optimised towards the 5:6 divider????
My only theory is that this is because the motherboard offers DDR2 1200 "out of the box".
