Windows 7 64bit on recognising 3.25gb Ram

  User-312386 09:59 23 Oct 2009

Hi all

I installed Windows 7 64BIT with 4GB ram

It only recognises 3.25GB

Any ideas please

Install 8GB of RAM and you should see 7.25GB. Probably your video card had 0.75GB of Video RAM and this is being mapped into the top end of your available RAM that Windows sees.

I have a dedicated graphics card with 256MB Ram and no onboard graphics!

Does your mother board allow for as much as 4GB of RAM? Perhaps there is a setting in BIOS that needs to be set for the mother board to recognise the installed RAM correctly.

You need to enable memory re mapping in the bios if your motherboard supports it.
If not you may find an update for your board on the manufacturers site.

madboy33©® Are you saying it only recognizes 3.25gig or it can only use 3.25gig?

  User-312386 20:53 27 Oct 2009

It says 3.25GB useable

Still think you may need to upgrade your bios from the board manufacturers website.
