If you're not running anything, the memory won't be used. Use the memtest here and see if you can fully load the memory. You will have to run multiple instances of it, but it should be able to max it out and test it too. I've tested up 32gb this way. Just don't overdo it or you'll end up swapping to disk. Let the last instance use 'all unused ram'.

You want to double check and ensure that you have placed your RAM DIMMs in the correct dimm slots. Typically this would be slot 2 and 4. Look it up in your motherboard manual.

If that doesn't work, test each DIMM on its own to see if you have bad RAM, or if you might have a bad ram slot.

I would say you have bad RAM. RMA it and get new RAM.

Was this purchased as a 16GB kit ?
How much RAM does the BIOS show?
Are you running XMP/DOCP ?
If this was purchased as a set, then you have to RMA both DIMMs....

Here is where the biggest factor of this comes in - What operating system are you running and are you running 32 bit or 64 bit, as 32 bit would definitely cause this issue, however, there are some versions of windows where the home version can only see and use limited amounts of RAM.

If you are running Windows 7 Home, that is likely your cause. Check out https://support.microsoft.com/en-us...less-than-the-installed-memory-on-windows-7-b

Windows 7 Home Basic has an 8GB RAM limit and will not let you use more than that.
