hi.

Not all of my ram is visible at post, nor in task manager; dxdiag sees all of the ram.

Two machines have exhibited this phenomenon, a 945gcm-s2l with windows 7 32bit, 2x2GB. post and taskmanager show 3GB yet dxdiag is displaying 4GB. blue is an ep31-ds3l with windows 10 64bit, normally 2x2GB until i added 2x1GB earlier today. post and taskmanager show 4GB and dxdiag shows 6GB. interestingly the pagefile was larger;~6GB(its on auto).

ep31-ds3l needs to be 4x2GB ddr2 800; blue is getting an ep43t-s3l with 1x4GB ddr3 1600



Have a great day.

 
Solution
32 bit windows is limited to 4gb of total ram. This includes all hardware addressable space (GPU, motherbd...)
So 3-3.2GB 5 left for to map the Ram in is quite normal.
