If anyone is interested, I managed to get the FULL 4GB to get recognized on my machine. Its an A8N32-SLI Deluxe and previously was only getting about 3.3GB.
- Update bios to v1303.
- Enable Memory Hole. (This is Important!!)
I also disabled the serial parallel port and a few other things but I’m pretty sure thats not of much concern.
Cheers.
