I have an HP elitebook 6930p running XP pro. It came with 2G installed RAM and I have now installed another 2G module - exactly the same as the original one. CPUZ says I have 4G installed RAM, the BIOS says I have 4G installed but system properties says 2.96G Any ideas?
Dave that 2.96GB is what the operating system is reporting it can access, system memory That is not the value of what is installed on the computer. Almost never is the system memory equivilent to the actual amount of memory installed on a computer/laptop. Go to start, all programs, accessories, system tools, system information. Under system summery you should find the value that XP knows is installed next to “Total Physical Memory”. If the total physical memory there is reported other than 4GB I would run Memtest on it’s extensive test to see if all of your memory is good and/or pull both memory sticks to verify you actually have 2, 2GB sticks installed. If all that comes back clean you have a problem with your Northbridge.
The problem is you are running 32bit XP Pro. XP will only recognize 3GB of ram. To utilize all your ram you need to update to Windows 7 or switch to 64 bit XP. http://www.tomshardware.com/forum/269155…
