2 SD 512MB PC-133 RAM 168PIN SD-DIMM ram modules reading only 128MB of RAM (400MHz)?

[stephenco]

I've 2 SD 512MB PC-133 RAM 168PIN SD-DIMM ram modules fitted to my aging motherboard but for some reason when I right click on My Computer and look at Properties it only shows 128MB of RAM (400MHz)?

I've tried changing the 2 slots over which incidentally are the same and even removing 1 of them but it continues to show only 128

Any advice appreciated please

You might need to boot into the BIOS and update the settings for installed RAM.

What is the motherboard or model of your system?

[stephenco]

Can I ask you how to update the RAM settings in the BIOS please? I can get into it ok but didn't see any settings for it

Also, its an old Packard Bell PC but I can't find the m'board details?

According to one site, you can access the BIOS set up by pressing the F1, F2 or DEL keys, but I have no personal experience with that manufacturer.

I suggest to try to run a "Mem Test" application to see for any hardware problems that youmay have with those memory modules.
