Can anyone help me? cause last time i was able to use 8gb ram. now its only 3.21gb useable. already tried unchecking the box from the msconfig. anything else?
your ram is faulty or you have the ram dims in different slots put them in the right slots if there is 2 white and two black make sure you use the ones close to your prosessor
if u have more confusion try linux live boot from USB n check RAM usage if still 3GB sure hardware problem or 8GB usage its will ur software/windows problem... simple basic troubleshoots... good luck...
A few people have already said - but I'll re-confirm.. You're allocating that missing memory to your APU .. It is an option in the BIOS. Essentially acting in the place of VRAM which a GPU would have, the APU's GPU (built in) has to rely on your system memory - and steals it. You can allocate less .. or more..
It is the apu using shared gfx. In other words it is dedicating you memory for use as gfx vram rather than inboard memory. The joys of using integrated laptop gpu
