[SOLVED] I have 12GB Ram, only 4GB is usable

[LunatiCultist]

So, if you readed my previous posts you know that i've been having trouble with a newly built pc. This time everything works, but the only issue left is that only 4GB of ram is usable out of the 12 i have.
I have checked that the memory is not limited in msconfig, checked in bios that the voltages are right, from what i know the two ram sticks are from a different manufacturer but both are the same voltage so it should work.
In the bios only 4gb appear, but both sticks are recognized, CPU-Z also recognizes both sticks and on the windows control pannel the 12gb show up but as said, only 4gb are usable.
On a side note, the pc doesnt boot up if i only have one stick of ram installed. Doesnt matter in wich slot or wich stick is plugged in, i have to connect both for the pc to boot up.
Since im using the integrated graphics the ram is pretty important, so i hope that i can solve it quick.

It seems like you may be using 32bit Windows instead of 64bit Windows. 32bit Windows can only address 4GB of RAM

Im not, im pretty sure my installation is 64 bits, and it says so in the control pannel.

It's not guaranteed to work if you have two different manufacturers of RAM.

So then, should i buy a copy of a stick i have? Or should i buy a kit?, Or is the problem another thing and i shouldnt buy anything?

Are you sure both your RAM sticks are working? Did you check each of the sticks individually?

I mean, the 8gb stick is the one not being used, so i dont know.

Nevermind, i just checked again and the pc only boots up with the 4gb stick plugged in, if i try to boot it with the 8gb one it doesnt work, so probably that stick is faulty or they're incompatible because of different manufacturers

Which RAM is causing you to not boot up? The 4GB ones or the 8GB ones?? Because I think there might be a faulty 8GB stick which is why it is not showing up the total of 12GB.

Well you would better RMA your 8GB RAM and you're good to go with the new ones.

The thing is, that 8gb stick came along with my motherboard, so if i try to refund it i would also have to return the motherboard, so i obviously cant.

I would definitely recommend you to go for replacement of that 8 gig RAM which is under warranty!!! Doesn't cost you a buck!!!

I just messaged the seller, hopefully i will be able to request a replacement and it will work this time, if i have any other problem regarding to this ram i will ask it in this same thread. For now, thanks for helping.
