Help needed with Memory Upgrade please

[f1ash]

Hi,
I have just installed two 512mb ram in my Sony Vaio laptop which
should now give me 1024mb ? My system information only shows 448mb.
When I boot up and go into the BIOS the 'Total Memory' is also only
448mb ?

Any advice would be greatly appreciated.

Thanks

I would suspect that you have not succeeded in installing the ram correctly,
or perhaps some of the chips are not compatible with your system. I would
put in one set of 512, test, and take it out to put in the other alone, and
test. If they both work, you probably have a bad socket (bank) for the
second set.
