old intel board not accepting dimm

[aburnside]

hello!

my girlfriend's system is an old, ap-style, system with i believe a 120mhz processor and 16mb ram in two 8mb simms. the intel 82440vx board (which i cannot find any documentation to online) has one dimm connector. the schematic in the manual shows it as dimm 0.

when i plug a 64mb pc100 (kingsington value ram) into the connector and boot, the system does not recognize the newly added ram. if i remove the two simms, the system doesn't boot. i took the ram and plugged it into one of my systems and it worked fine. open for suggestions.

can't find any info on the board.

Only though is if it's that old it may require pc66 memory.

Older motherboards weren't configured to work with the faster memory

Not real sure but you might look in the bios to see if you have to turn one off to use the other. I have never heard of this but it might be worth a try

Ditto on Brian's PC66 suggestion. I have seen this situation so many times I could not even begin to count them.

Some of the older 66-MHz-bus systems just will not see 100-MHz memory--or, if it sees it at all, not see all of it.

Just last week, I installed a 64-Meg DIMM into an older system. It saw 16 megs of it. I put in a 256-Meg and it saw 32 Megs of it. I put in a 512 and it saw 64 Megs. Then there are those systems like yours that see none of it.

Ditto everyone else on the pc66. Sometimes those boards will see pc133 even when they will not see pc100. I have an old FIC 502 in the basement that is like that.
