Specs beforehand (Upgraded HP m8530f): AMD Phenom X4 9550 @ 2.20 GHz / HIS 256MB Radeon HD4350 GDDR2 PCI-E / 6.0 GB PC2-6400 DDR2 RAM / 750GB SATA Seagate Barracuda HDD / ASUS M2N78-LA / CoolerMaster 500W PSU
So, this computer comes stock with 5.0 GB of RAM. So in the four slots, there is a 1 GB - 1 GB - 2 GB - 1 GB configuration. Today, though, I got another 2GB stick, so now I have a configuration of 1 GB - 1 GB - 2 GB - 2 GB. However, after I booted up... I went to Computer Properties and it says that I only have 5.0 GB Usable memory. However, I checked online and for Windows 7 Pro 64-bit, the max supported memory should be much much more.
Any ideas? Are there questions like this already? (oops)
EDIT1: for Sim...
