Hi guys...

I have ans asus p5gl-tmx mobo...

I installed this PC wizard software from Digit DVD and the specs u c below is that of the RAM...

Can u guys tell me the technical aspects of this info...?

Most importantly, the max freq speed of RAM my mobo suppports...

Help me guys...

Hey what you got there is all technical! What more technical do you want?? :roll:

Anyway you might've figured out that your mobo 256MB DDR RAM. The RAM does not support hardware based error correction control (ECC) and that

RAS = Row Access Strobe
CAS = Column Access Strobe
These are digital signals used to enable RAM modules and read data in words. The tCD and co. refer to timing. It's best you get hold of an engineering text and look at signal timing and clock skew.

Width refers to the number of bits that can be read simultaneously (parellely). The FSB speed is 133MHz and the RAM speed 200MHz. Since it's SD RAM, it has to be refreshed. The refresh speed is also given.

If you want a line by line explanantion, then you'd better get hold of an engineering text on memory.
