My computer had 32 MB of memory consisting of 4 8MB chips installed on a SIMM. I wanted to increase it to 128MB so I bought 4 32MB chips on a SIMM and installed it in place of the 32 MB. The computer would recognize only 64MB of RAM. How can I get it to recognize the full 128MB of RAM?
Response 1: Some motherboards have a specific sequence in which memory modules must be added. I presume you consulted the motherboard manual about this?
Answer: Yes I did. I
used slots 1 & 2 on the motherboard.
Add-on to Response 1:
What I mean is: 32MB in Slot 1 and 128MB in Slot 2 = 160MB, may not be a recognizable configuration to your motherboard. Order of installation may be important.
Sometimes memory SIMMs are difficult to seat properly in their slots. Are you sure they were properly installed?
Answer: Yes the slots were very difficult to access and I have the broken
fingernails to prove it. I am sure they were seated properly.
In my experience some motherboards do not properly recognize the memory modules of some manufacturers. That may be your problem. Suggest having the memory module provider install them.
