I have purchased 2x4gb memory modules (total 8gbs) and have placed them in dual channel configuration on my Gigabyte motherboard.
I then noticed that Windows would detect 8gb installed (4gb usable) in system properties and 4gb hardware reserved in resource monitor.
I have searched the internet for possible causes. I know that the ram modules are fine, in fact I had this problem on my old 3x1gb modules but I didnt realise that 1 channel would be missing.
I have attached this image from my bios to show the problem:
As you can see, the bios detects the ram installed in the Slots but Enabled Slots only show 1 4gb module installed.
In CPU-Z, the dual channel configuration appears to be enabled, even though the BIOS only enables 1 slot:
I have also read that this problem can be caused by bent pins in the CPU socket. I have taken these images and circled the pins which appear slightly bent. I just wanted some opinions before I touch them if these pins are indeed bent. Could this be the cause of my missing ram?
Here are the images of the cpu socket:
