4 GB Installed 2 GB Usable Memory issue.
I just built a PC and installed Windows 7 Home Premium x64. My system shows 4 gigs of ram installed but only 1.99 GB usable. I'm not sure what else I can check here. I'm using an EVGA P55 LE with the latest bios.
Latest Bios
Memory remapping enabled
Check MSCONFIG max memory isn't limited.
I noticed that on EVGAs performance tool the memory is reading as single channel when it should read dual channel.
I'm using a Radeon HD 4890 1GB DDR5
OCZ Low Voltage Platinum PC-10666 Dual Channel 2GBx2 DIMMS
I've been scouring the internet in search of some sort of answer. Please Help!
