Dimm slot problems

[werch]

So i have a GA-970A-UD3 which supports dual channel memory, and 2 G.skill ripjaws x 1866 4 GB sticks. When I seat them in a way that would support dual channel, it only registers 6 GB and says 3.98 is available. However, when I put the sticks in the slots right next to each other, then it registers all 8 of it. So i am wondering- does it have to do with the dimm slots themselves? it just kind of happened one day, but do i need to update anything to fix it?

My question does it still say 3.98 available when it registers 8? Are you on a 32 bit version of Windows?

are you getting this information about RAM capacity from your UEFI or windows properties?

it only says 3.98 when it registers 6. when its 8, it registers 7.98. and i am using windows 8.1 64 bit.

then what does it say in the UEFI on boot/POST? might have to access the UEFI to find out.

what version UD3 do you have. lower lefthand edge, it'll say REV X.X

Okay im there, but i dont see anything to do with RAM, just harddrives. And sorry for all this messed up quoting and stuff, im on a phone right now

My question is, how do i get to the uefi?

UEFI is the BIOS screen you go by default. Unless you have either older mobo or have chosen to use legacy (like me).

Press Delete as you power on PC.

UEFI and BIOS are the same. UEFI is an updated GUI application for mouse use.
