Windows 7 Professional 64-bit SP1
Wrong RAM Information


please if anyone can give me a good solution or a way that can help me about my DDR3 RAM.

I'm using DELL Optiplex 790 running Win 7 Pro sp1 x64bit also using latest BIOS of motherboard (A18) and recently i'm using 16GB DDR3 RAM and after a week i add more 8GB. I check in BIOS RAM is perfectly working detected as 24GB and so i boot up to Windows but i get annoyed when i checked it it's only 20GB RAM has been detected.

P.S. i also check the msconfig-boot-advanced options-max memory (UNCHECKED)

please help me..
