I just doubled my ram but my system only recognizes 64mb of the new 128mb memory stick. So, instead of 256mb I only have 192mb. I don't have an onboard graphics card which may use up ram. QDI advanced 9 is my motherboard. I am a novice to anything hardware related but I have noticed this difference between the 2 memory modules sizes(via SPD):- 2 ranks 4 banks (existing memory) 1 rank 4 banks (new memory) Could this be the reason. This is the first time I have upgraded any thing on my pc, so I may have overlooked something ovbvious. Thanks.

What are the specs on your new memory? What display adapter do you have?

TMI. How much memory is reported when you use the new stick by itself? Does your new memory have a brand name?

cpk, I had the same problem when I moved a 256MB stick from one computer to another - it was only recognized as 128MB. The problem, as was replied to in this forum, is that the memory module is high density and my older motherboard was only made to support low density RAM. See my original post here. Seeing as how you have ISA slots on your board, this is almost definitely the same problem. Michael J

Yup, it's a density problem. Nothing you do will get the full amount of that memory stick recognized. You'll have to buy the proper type of memory for your board ASUS A7N8X-X Athlon XP 1800+ 8.5 x 200MHz 1024MB PC3200 2.5-3-3-7 Asus A9550GE/TD 128MB WinME/WinXP Pro SP2
