Memory Expansion 1

[milodunbar]

My 2-year-old computer will not accept 512mb SDRAM DIMMs. SDRAM is not the problem. Rather, it is the size. Max acceptable DIMM size is 128mb. QUESTION: Is this memory limitation imposed by the Phoenix BIOS, or the 440BX chipset, or something else on the motherboard?

Thanks for any help.

Try visiting your BIOS manufacturers website and finding a BIOS update.

Mike, are you saying that the limitation IS imposed by the BIOS? I don't want to buy a new BIOS if it will NOT free me of the memory limitation.

for BIOS chip upgrades. Might be cheaper than a new motherboard.

Thanks Berton. Looks like a good place. However, BEFORE I buy an update, I sure would like to know if the update will enable a LARGER RAM memory. That is NOT listed as a benefit at

The i440BX chipset can manage up to 1GB of memory organized in 8 rows and physically up to 4 slots. I.e. up to four two-banked modules. If your motherboard have less than 4 DIMM slots the total memory amount supported is less than 1GB.
