Hey, guys. I just finished building my computer only a couple of days ago. I have installed 8gb of ram. In the diagnostic it says I have 8GB of RAM installed on the system tab but in the display tab it tells me approx. Total Memory: 4049MB. My question is, is there something wrong? I feel there is and if so, what do I do to fix it? I have tried taking it out and re-placing it but that didn't work.
if the ram seen in the bios and with cpu-z it could be a bug with windows. check in the bios in you have a tab/button that says memory remapping. it should be on.
Check to see if selective start is selected.
If yes, go to the boot tab.
Click "Advanced Options".
Deselect the maximum memory option if it is selected.
Also, you can optionally select the number of processors to increase the boot speed.
Click on apply to apply the new settings.
Reboot the computer. Once the computer is rebooted, right click on "Computer" on your desktop and select properties. Installed memory should now show just the memory installed rather than the 2 components (installed and usable).
Open the Resource Monitor, see below, what is listed under the 'Hardware Reserved' and in the BIOS how much memory is allocated to the iGPU as shared memory; BIOS Integrated Graphics Share Memory/DVMT Memory?
Often simply re-seating the RAM in the Black DIMM slots corrects the problem if the RAM isn't damaged, and make certain the DIMM slots are all fully locked down.
