Hi

I've just installed a 512MB RAM (166MHz) on top of two other 512MB (200MHz) sticks which are paired making 1536MB. However, do you think that this is worthwhile as the PC supports dual channel and am I actually slowing it down by adding this extra stick?

cpuz report below. Thanks in advance.

The Ram will run at the speed of the slowest stick (166MHz), although the system will benefit from the extra Ram.
