Both RAM Modules not working, shows "Installed"

[TheLetterD]

Hello
So...
Like the title says I have 2 modules of 4 GB Corsair Vengeance RAM in my PC. Only 1 Module is working and it shows 4Gig in my BIOS. My system properties (Windows 7) shows that 8.00 GB is installed but only 3.45GB is usable(512 MB to my APU's IGP)
I tried taking them out and plugging them back in but nothing happened :/
Also, cant find anything about RAM other than Messing with it's Clock speed in my BIOS. :/

you may have installed 32 bit os. install 64 bit os and your problem will be solved.

Nope its 64 Bit.
Plus it used to work before but for some reason all of a sudden

Try resetting the CMOS setting.

How many ram slots do you have? try inserting both modules into similar colored slots.

 

[TheLetterD]

Only 2 RAM Slots! :/



@ Topgear How can I do that? :/

Turn the PC off. remove the CMOS cell from motherboard. keep it removed for 15-20 mins. Then insert the cell and turn on the PC.

Glad that your problem is solved. How old is your cmos cell?

I bought the Motherboard in February so Im not sure tbh, I guess itll be a December2012/Jan2013 one?

That's almost a new motherboard then .. so don't worry much about the CMOS battery.

Yup! I guess
