Ram Issues

I got a brand new case, mobo, ram, and processor. However, once everything was installed, the rig wouldn't post or beep, just cycling power every few seconds. With borrowed parts from a friend, I realized it was the ram. Now, my pc runs fine, however it only recognizes 4 gigs of ram. I tried moving the two sticks around and got the following results

-either stick of ram in the 1 or 2 slot works fine
-both sticks in slots 1 and 2 posts and runs, but only recognizes 4 gigs of ram
-dual channel with either using slots 1 and 3 or 2 and 4 both cause the pc to not post.

I believe the problem is not the ram but the motherboard, and I am trying to avoid RMAing it if possible. I'm fine with running the ram in single channel so long as both sticks work. Is there any bios settings that could affect this?

specs:
i5-3570k 3.4GHz
4 (hopefully 8) gigs ram
MSI Z77A-G41
Nvidia GTX 570
640 gig HD

Thanks for any help and sorry about the read!

  1. LGA 1155 requires 1.5volt ram since the CPU can get damaged from higher voltage than 1.575volts.
    I would return the board if it is indeed faulty slots since consumer should not accept faulty products.
  2. MSI boards are sometimes picky about which brand of RAM they use. Go check the site for a list of compatible RAM brands.

    Runs with voltage 1.65.

    1.65v is acceptable
    1.5v is ideal
