Ive just tried again...and can only push the FSB to 230 max...anything after that is just keeps looping at boot.

Could this be down to memory timings do you think?

If so what should i really be changing them too

Is the PCI BUS locked at 33MHz?

Can anyone with this Mobo tell where i can find out?

Thanks

Your problem could well be that your memory timings are on Auto.

Set the following.

CAS Latency: 2.5
Ras Precharge: 4
Ras to Cas: 4
Tras: 8

Also set Command Per Clock to Enabled if using 2 sticks of memory or Command per Clock to Disabled if using 4 sticks of memory.

All of the above is in DRam Config.

Thanks ill have to give that a try .

Ive just found a few settings im currently at 265fsb and cant get any further the settings im using are

fsb - 265
ldt ratio - x3.0
ldt width - 16 16
cpu/fsb - x9
pci exp - 100mhz
cool n quiet - disable
cpu startup - 1.425v
cpu vid control - 1.425
cpu special control - auto
ldt voltage - 1.3v
chipset voltage - 1.5v
dram voltage - 2.6v

dram config:-
dram freq set (divider's) - 133=ram/fsb:02/03
cpc - enable

Ram cas latency - 3

you think i could squeeze any more out of it?
