Alright guys, i've got a abit ip35-e, 2gb geil ddr2 800 ultra low latency and a e2180. I seem to be alright at getting it running at 3gb (10x300), but then because of the ram divider i've got 750mhz or 900mhz ram instead of 800. It won't post at 900mhz unfortunately.

So i set it to 333fsb and adjust the multiplier to 9 (3gig) and arrange the ram divider to set it at 800mhz... perfect you would think. But it won't post! can anyone tell me why? the cpu volt is set at 1.375, which is stable at 10x300 so i don't think the cpu needs more volts. i've tried it with more volts anyway and it doesn't make any difference.

Do i need to up the voltage on the ram or anything? even if i haven't clocked the ram does it need a bit more because of the high fsb? i've uped the north/south bridge 0.15 max and that doesn't seem to make much difference.

do you think i've hit a fsb wall? is it the board? do i need to adjust the ram volts?

What volts are you giving your ram? If its defaulting to 1.8 that probably wont be enough.

Also might be worth seeing if you can boot at 8x375 with the mem at 750, these chips can usually handle that kind of fsb quite easily.
 
same problem for me if I tried keeping the ram at 800mhz. Got same cpu, ram but use the abit ip35 standard. Way to get round it is to just use the 1:1 divider and push your fsb to hopefully 400 where your 1:1 ration gives your normal ram rating.

Using 1:1 i can get 350fsb out of mine but no higher, goodluck

i have that CPU but on a gigabyte p35-ds3l. I usually run 320x10 with the ram 4:5 400mhz. I can run at 400x8 with the ram 1:1 400mhz but windows, orthos and other programs report the CPU as 4ghz. Anyway around this ?
 
windows only reports that because it ASSUMES it's still got a 10x multiplier, so just ignore it.

I've done a sort of work around by setting it to 900mhz RAM and loosened the timings to 5-5-5-18.

It seems really strange, i got it to boot at 400 but cpu-z reports it as 200mhz fsb - not 400 :S my 3dmark score gets 1000 worse as well *sigh* can anyone shed any light on this?

disabled thermal control, C1 etc etc garbage in bios? Basically make sure speedstep is disabled so you dont see it knocking your FSB down whilst idle
 
Manually set you mem to 400fsb and your mobo to 400fsb, set your multi to 8. you will have your cpu running at 3.2 ghz and your mem and mobo at a 1:1 ratio.
You may need to up the nb volts and certainly up the VCore.
