Memory Problem

[Big Fella]

Hi Guys,

This is my first post so please bare with me, here goes!!

I am trying to upgrade my memory on my old Pentium II machine.

I have got a stick of 512mb SDRAM. My only problem is that once I have fitted this in, it is only reporting it as 256MB of RAM. Am I missing something here?

I got to test it on a colleague's PC and it reported it fine as 512MB (although his was a Pentium III)

Can anyone out there assist this newbie!!

Details are:

PC: Pentium II 266 MHz
Memory: Twinmos PC133 512MB (SDR/CL3)

Many Thanks

what kind of computer/motherboard is it? if was a mass produced (oem) build, state the brand and model. otherwise, downlaod and run cpu-z, looking under the motherboard tab.

Thanks for the info mate.

Using CPU-Z it reports the memory as 512MB, but the board is only seeing it as 256mb.

The motherbaord is an Asus P2L97 and when I checked the specifications of this it said it could only handle a maximum of 386MB. Am I right therefore in thinking that if I use anymore than this it wont register it but will just halve whatever the capacity is?

Many Thanks

in that case, it is encountering addressing problems trying to use the 512mb stick. you'll need to use sticks whose sizes are supported by the motherboard to get all 384MB.
