It wasn't a DDR...Generic RAM of some sort (128 MB don't have any Idea) It runs on my old Pentium 200Mhz (PC I use for interfacing projects during college) but has a problem when mix with my PQI 256 SDR SDRAM.

What the hell I am trying to do? Killing my curiosity before it kills me!

I'm still building PC.

I know about the beeps...Thanx u'r Evilness But NO beeps except for a 1 short beep...U know what it means..a OK.

How come POST did not detect any error or HALT for that matter until MSDOS boot-up.

Note: The package of the Mystery RAM, has Chips on both sides. while my PQI SDR SDRAM has chips only on 1 side.

Is it possible that I mix a buffered and unbuffered rams? I leave it to U guys.
