Question Gigabyte motherboard reading only half RAM installed..!!

[WesElMak]

Hey geeks at Tom's Hardware forum..



I've got a Gigabyte GA-B75M-D3H motherboard with Dual Channel RAM slots, since 2013 I have assembled the PC with 2 Kingston HyperX Blue 8GB RAM just to realise recently that I'm only using 8GB in total instead of 16GB 🤓

When I install only one stick at a time the MoBo reads only 4GB instead of 8GB. The RAM slots are 2 white and 2 blue, any advise mates?

Thanks.

What are you using to determine the usage? Task Manager? Third party software? If it's third party, make sure it's the most up to date software version.

Can you provide a screenshot to help illustrate?

What is the part number of the RAM? It will look something like HX318C10FBK2/16.

Hi Keith12,

The RAM size is showing on the BIOS as the attached photo.

Also, on Windows is showing 8GB only.

Thanks. As a matter of interest, run an instance of CPU-z and click the memory tab and report back.

Its possible it's a glitch. Have you recently updated your BIOS? When was the last time you did a fresh install of your OS. Check CPU-z first and try the varying combos of slots populated whilst noting if CPU-z is displaying the correct info.
