problem with AN50-R

[lostark374]

seems no matter what i do i cant get my ram to run at system speed

heres the run down and specs:
Shuttle AN50-R with cpu and mem vmods
amd 64 3000+ @2700 10x270
cosair xms 3500 v 1.2 (bh-?) 512x1

ok so any fsb above 225 will not run with the ram @3200 i have to set it to pc2700 to get it to boot i know its not the ram ive had both my cosair sticks up to 255 2-2-2-5 @3.2v (i have 2x 512 sticks)also thought it was the ram at first so i bought kingston hyperx pc4000 2x512 and it wouldnt do above 225fsb @pc3200 settings either
anyone have any ideas?
need any more info?
LDT is set at 2
cooling is stock mach1

XMS3500 doesnt work too well with the AN50R. Ive tried 4 sticks and got about the same result that you did.

[lostark374]

what about the pc4000 hyperx?

[CodeRed]

never used pc4000 hyperx so I cant say

Is SATA enabled?

what volt are you giving to rams maybe it is the problem bh5 always need lots of volts

[Popcicle]

XMS V 1.2 is CH-5. The V1.1 is BH-5.

To really have any luck with the AN50-R a guy
needs to run 2 X 256mb of single-bank BH-5.

This will get you some FSB.

Try and find some 3200 BH-5 and you'll be in business.

change to cas 2.5. corsair will run great @ 1:1 after that..

the difference between cas2 and cas2.5 is in the order of 2 to 3 Mhz at the most

ok i will answer all
yes sata is enabled but i have tried it without
have tried the ram up to 3.6v
i am currently running thr ram at 2.5-2-2-5 3.2v same results ...have tried very loose timmings ...same result

[lostark374]

double checked ...the ram is v1.1

[Confused_User]

All corsiar 3500 xms is BH-5.

what i am saying is that dosent it seem wierd that even the pc4000 wont run at 250 (its rated speed)?
