Windows 7: 8gb ram only reading as 4gb

Here are my CPU-z results, it appears only Slot 2 is being read, so I'll try testing both slots and both ram sticks and see if that sheds any more light!

Evey thing points to one module of ram being seen as 4 gigs.

Here is a tutorial to test you ram. It does take some time. At least 8 continuous passes need to be done or until bad ram is found.

RAM - Test with Memtest86+

Could you post a web site of the exact ram you are using?

Is it this?

Aaaah! Typical...it was me

I tested both slots with both sticks individually and they all worked, and after a couple more attempts at trying both sticks at the same time both are reading and I have 8gb of RAM working!

It was quite tricky aligning both at the same time, and the one in slot 1 must have not been properly connected.

Drama over and thanks all so much for your advice!

I'm I correct in assuming that both ram modules were not install properly and now they are?

Could you post another picture of Resource Monitor so I can have another look?

Remember post # 5

In most cases that means ram installed incorrectly or the wrong ram or ram settings.
Try something simple first. Re-seat both sticks of ram and then Reboot a couple of times and then take another look at the ram in Resource Monitor. It's possible that one stick of ram in a match set could be bad but not likely.
