I am trying to upgrade a 6 year old desktop containing a MSI KM2M motherboard, an Athlon XP 1800+ CPU, and 256 MB of RAM (ValuRAM 2.5v KVR266X64C25) with a 1 GB SIMM, ordered to match (in clock speed and voltage) the 256 MB stick, for a total of 1.3 GB of RAM. The 1 GB SIMM is an HP branded 128 x 72 @ 266 MHz.

Unfortunately, the motherboard refuses to recognize the second stick, which is firmly in place. If I put it in alone (without the 256 MB stick), the computer won't boot, but emits beeps without displaying anything; if I put the 256 MB stick and 1 GB sticks in, the BIOS and Windows only recognizes the first stick (224 MB + 32 MB shared). This is really annoying, considering how slow the 224 MB we have right now is with anti-virus, Flash videos, etc. Does anybody know what might be wrong?

"128 x 72 "

The 72 should indicate it is "ECC" [Error Correction Code] memory.

Count the total number of chips on the stick.
If the number is odd it is ECC memory
If it is even it is non-ECC memory.

If you have ECC memory it may not work on the motherboard as not all motherboards support it.
