8gb ram on integrated graphics?

Solution
With Integrated (Processor) graphics, you can select in your computer's bios how much RAM to allocate it. This comes off the total installed RAM, so your system memory is lower than total RAM. However, because it's possible for the graphics to use more than it has been allocated by sharing the remained RAM, the "total available graphics memory" is just referring to the total amount of installed RAM.
Just means that your integrated GPU could use system memory for graphics if necessary. You have 128mb of dedicated VRAM which is faster than system memory and is given priority when storing graphics. When more is needed, shared system memory is available.
