BIOS only recognizes 4GB RAM but Windows 8 x64 sees 8GB Tags: BIOS RAM X64 Windows 8 Memory Last response: January 16, 2014 4:46 PM in Memory Share Dufuss January 16, 2014 3:55:07 PM I had a 4GB RAM stick, but I decided to upgrade. So, I just bought another 4GB stick. I have an Asus M5A97 R2.0 Motherboard. The first stick of RAM is Spectek Select 4GB DDR3 1600 while the second stick is Kingston 4GB DDR3 1600. No matter what slots I place the sticks, BIOS only recognizes 4GB of memory. I've done each individually in different slots to ensure that both sticks work and all my slots work. When I go ahead and continue with Windows 8, it detects 8GB but says that only 4GB are usable. Are these two particular brands incompatible or is there something I am missing?
