Hardware Talk :: Unsuccess increasing RAM

Now i understand!
486 and olds 586 (60 - 100 MHz) use type FPM (Fast Page Mode) memory and not compatibility with EDO (Extended Data Out) memory.
If my memory is type EDO then not compatibility.
Manufacturer ID RAM is: POWMEM 9646. If EDO or FPM ?. I that Not it knows. Somebody knows?

You need to read the part number on the RAM chip itself.

But ulitmately, knowing the RAM type isn't gonna help your situation. Either the stick works with your PC or it doesn't work with your PC.

FYI, some older MBs required the RAM to be installed in pairs (groups of 2 identical or nearly identical sticks per bank).

If you can find out your montherboard part number, you might be able to find an old manual in PDF format on the internet that will provide more information.

Many tanks cbagger01. You have reason.
Part number on the RAM chip is: MT4C4M4E8DJ-6 and is EDO RAM. Well, not luck.

You may have to modify the jumper settings in the motherboard to tell it what size the new memory is.

It is possoble that there isn't any autodetection of memory.

It is also possible that the motherboard takes memory in pairs, then you would have to have 2 identical memories.

I remember that when I had a 120MHz 486 I was happy that it had memory autodetection. My parents 33Mhz 486 didn't have it.

This motherboard documentation difficult to find but is evident have memory autodetection because detects 16 MB when boot with a pair of 8 MB memories and detects 8 MB when boot with only one 8 MB memory.
This computer can to run with only one memory but i also had used 2 identicals 32 MB memories within success.
Tanks anaconda.
