BIOS sees both modules but only 4GB

[Mounty_078]

Hello, my friend and I just built a PC for him and in the BIOS of his MSI FM2-A75MA-E35 motherboard in Memory-Z it says there are modules in both slots, with the name and everything (G.Skill RipjawsX 4GBXL) but it only registers 4GB of RAM in total while it's supposed to be 8GB.

Are you sure that you installed the 64-bit version of Windows? The 32-bit version can only use a bit under 4GB.

I never said something about Windows. The BIOS isn't seeing the 8GB not Windows and yes I'm running Windows 7 64-bit.

Oh, sorry for the misunderstanding. Can you provide a link to the RAM you bought? Try using each stick of RAM in both of the slots individually, that way you can figure out if one of the slots or the sticks is faulty.

Well they both work because when I put them in slot 2 the PC boots up but when I put them in Slot 2, it doesn't, everything just starts spinning but no display. I just don't understand why it recognizes that there are modules in the slots with all the information and voltage and every other piece of information but it won't recognize the memory.

Yeah, sounds like one memory slot on the motherboard is defective; You'll probably have to RMA the board.
