I want to upgrade the RAM in one of my desktops. I can buy a 512 board for a good price but on running everest, I get the following DMI report:

Memory Controller Properties:
Error Detection Method None
Error Correction Single-bit
Supported Memory Interleave 4-Way
Current Memory Interleave 1-Way
Supported Memory Speeds 70ns, 60ns
Supported Memory Types SPM, FPM, EDO, Parity, ECC, SIMM, DIMM, SDRAM
Supported Memory Voltages 5V, 3.3V
Maximum Memory Module Size 256 MB
Memory Slots 6

I only have one 128 card installed and it divides it into 2 64 modules:

[ Memory Modules / BANK_0 ]

Memory Module Properties:
Socket Designation BANK_0
Type DIMM, SDRAM
Speed 70 ns
Installed Size 64 MB
Enabled Size 64 MB

[ Memory Modules / BANK_1 ]

Memory Module Properties:
Socket Designation BANK_1
Type DIMM, SDRAM
Speed 70 ns
Installed Size 64 MB
Enabled Size 64 MB

My question is: Since it´s saying the maximum memory module size is 256, can I use the 512 card and it will divy up into modules? It´s confusing me. If someone has a tutorial on this, I would appreciate it. Also, can I use the 512 card as long as it is on the supported memory types list as to compatibility? I´m assuming yes, but would appreciate a confirmation from one of you experts.

Thanks in advance,
