Recently replace one of my defected 1GB PC2-3200 with a 1GB PC2-4200 in DIMM2.
This is how my BIOS look like.
Memory size: 2.50 GB
Memory speed: 400 MHz
Memory channel mode: Dual Interleaved
Memory type: DDR2 SDRAM
DIMM1: 1 GB
DIMM3: 256 MB
DIMM2: 512 MB
DIMM4: 256 MB
BIOS only detect 512MB of ram in DIMM2, but my total ram showed is 2.5GB.
How is that possible?
