i just installed a 1gig memory stick in an old computer which previously only had 256, now the computer only recognises 512 mb instead of 1 gig. The computer is a Compaq Presario SR1500NX running win. xp. and is upgradeable to 1 gig.
I came across this in the hp support site
"To find the amount of RAM per slot, divide the maximum amount of memory that the computer can hold with the number of memory slots on the motherboard"
the max for this pc is 1 gig and there are 2 slots so i guess thats why its only recognising 512mb, but I was wondering if there was anyway to force it to recognise and also if I decided to leave it at 512 could that pose any problems?
thanks.

It's possible that the board only supports two lots of 512Mb and will not talk to 1Gb sticks. The only resolution round this is to change the board.

yea i thought that, but I was wondering if leaving it at 512+256 could pose any problems, it seems to be running fine for now.

I myself got a mobo with 4 slots supporting only 2 GB in total, so I can only stick in 4x512 modules. Gateway didn't update BIOS, while ASUS did

Leave it as it is. If the computer runs well on 512+256 then that's fine. Nothing to worry about.
