Hi all, I just installed Windows 7 Ultimate 64 Bit RTM version. Config is Intel Original G35EC Board, C2D7200, 4GB Transcent RAM (2 X 2GB). When I installed only OS it properly shows 4 GB RAM. After installing all application, Office 2007, CCCleaner, NFS most wanted, RAM is shown as 4GB (3.26usable). Why RAM limit on 64 bit OS?Mukesh Sutar

Update ur BIOS and see if u have the Memory Remap Feature: Enable in ur BIOS. regards I want to be a MVP! | Computer Technician

Hi, Are you using an aditional Graphic Card? I guess it`s routed to the On-Board VGA of the G35EC Board which is working proberly after you installed the Motherboard Drivers. The On-Board VGA is using a Shared Memory from your installed RAM. So deactivating the On-Board VGA off your Motherboard should solve it. Dennis

Mukesh Sutar Hi MukeshPlease see the following article for a description of this issue.The system memory reported as (usable) in the System Information box in 64-bit Windows 7 may be less than the amount of installed RAM Hope this helps. Thank You for using Windows 7 Ronnie Vernon MVP

Thanks Ronnie for sharing this. It worked, actually when I checked using msconfig, maximum RAM was selected as 0, after removing the tick mark and rebooting the machine, 4GB RAM is showing properly. Thanks once again. MukeshMukesh Sutar
