Memory running at 754Mhz instead of 800

Hi,
I have the crucial balistix pc6400 but it is running at 754mhz instead of 800.
I have the memory clock frequency set to 800, the cpu frequency is set to 200
and multiplier is set to 15x. I dont know what other settings to change to get it running at the correct speed, motherboard is a asus crosshair,
Thanks.

Anyone?

Tbh I'm not too familiar with the AM2 set-ups.

Is CPU-Z reading 377mhz?

normal i believe.

set to 200 = 1:1

200*15 = 3000, 3000/? = 800

?=3.75, must be integer, so go UP for safety (never exceed stock) = 4.

3000/4 = 750mhz

*edit*

remember, on amd, ram speed is related to cpu speed, not fsb. all cpu's have odd areason the ram speed table, eg the 4800+ runs ddr400 @ 400 on 200mhz setting, but runs it at 160 on 166 setting, and 171 on 180 setting. 133 works at 133 however

its cos on amd cpus the memory is in relation to the cpu... and it is full numbers only... 3ghz / 7 is too high and 3ghz / 8 is 375, then x2 = ~750.

Ok. I understand now thanks for the help

Is the memory voltage set to 2.2v?
