Re: Ram confusion please help
Onboard GPU. What that means instead of having dedicated video graphics processor and dedicated video RAM chips, the CPU does the video processing, and system RAM is used as video RAM. So if you have 4GB of RAM, and BIOS is set to 512MB shared graphics, the OS is given 3.5GB of RAM.
Some newer CPU's have half decent GPU's built into the CPU itself so it's not that bad, although it will still use system RAM, which is considerably slower than dedicated video RAM. If you're not a gamer then it doesn't matter.
