u need more mhz to last full your 250mhz mem clock,

by a 3200+ 200x10 , the cpu cant get full data transfer because it have to low mhz. für the 200mhz fsb so u have 4,7gb

with 200x11 u have more by same fsb :P look at the percent in sandra

Run unbuffered sandra, buffered is dependant on CPU clock speed and fsb.

In Memory bench there is an options selection area ( Pencil and paper-lower left edge on the sandra I have).
You have to uncheck some things, so it looks like this:

:slap: u need more mhz :P to use ur fsb speed effeiciency , so u can get 95% or max 98%.


but u got a 3000+ u can only get more mhz by more fsb :D 3500+ is best for overclocking :D

now
proc 300*9 with 5/6 divider for ram running 250

much better results 7228/7171 and better effiiciency 92%

RAM is actually running at 245MHz. Read this thread (http://www.xtremesystems.org/forums/showthread.php?t=41595&highlight=real+memory+speed) for more info...
