Does my processor support 8Gb DDR3 Memory? Motherboard is ASRock G41C-GS

Motherboard determines that. And yes, it supports 8GB of ram, but it has only 2 DDR3 slots.
You can't use DDR2 and DDR3 at the same time.

- Supports DDR3 1333(OC)/1066/800 non-ECC, un-buffered memory
- Max. capacity of system memory: 8GB
