Motherboard won't allow me to use more than 4 gigs of ram

So, I have 8 gigs of Ram
(Corsair Vengence - Blue)
It was working fine in my motherboard, unItil I had to remove them so I could switch my case.
But, when I got all the parts together in my new case, it only detected as 4 gigs usable on the windows system settings. So, I went in my bio to also see that this was the case in the bios as well.
No matter what combination I put the ram in ( 2 - 4 , 1 - 3) it still only detects as only 4 gigs.
Although, the motherboard does recognize that the sticks are there.

  1. the first image shows that there is 2 4GB Sticks. Download nova bench for PC and run the tests and update on what the ram memory in MB is (when tests are over). That software will test how much is installed and able to be used.

    Why does it say 1066MHz in the first image, then 1866MHz in the second?

    I took them at different times.
    Thanks. I'll run the test, and see what comes up.
  3. What OS are you running? Is it 64-bit?
  4. if it aint 64-bit then it's 32 bit.

    If you're responding to my post, I'm very well aware of that. The point I'm trying to make to the OP is that if he isn't running a 64-bit OS then he won't be able to utilize more than about 3.2GB - 3.5GB. If he is running a 64-bit OS then we need to figure out if the problem is with the RAM or the motherboard.

    That was in response to the OP, I am aware of that you would know that. If it were directed at you i would have quoted it to you. This is just to let the OP know what OS bit he has if it isn't 64. So in turn he could look into his issue as well to see what 32-bit OS's would have with his Ram misreading problem.

    From the first pic it very clearly shows 8GB detected in the BIOS.
    From the Second Pic it very clearly shows 4GB detected in the BIOS.

    Firstly, a question to the OP. Which one of the pics is correct when you detected 4GB in the Windows Settings?
    If it was the second pic..... obviously, if only 4GB was detected in the BIOS , only 4 GB is going to go forward to Windows or less.

    Have you checked in the windows settings to not have ticks in the Max Memory Box?
    msconfig>Boot>Advanced Options>Maximum Memory
