I have 4 sticks of 2x2GB Corsair Dominators, all identical, came in a box together. Just recently installed windows 8.1 64bit. No overclocking has been done. I can only use a maximum of 3 sticks because of power limitations, but 3 is fine.
It is dual channel, but that is not important to me, using them as single is sufficient for what I do with my computer.
All the sticks are in perfect condition and work on my friends computer. My old ram works on my motherboard and shows up completely.
When I put 1 stick in, in slot one, 2gb shows up when there should be 4.
When I put 2 sticks in, whether I go slot 1 and 2, or 1 and 3, only 4gb shows up instead of 8.
When I put 3 sticks in, slots 1, 2 and 3, only 6gb shows up instead of 12.
When I put 4 sticks in, it doesn't post.
I have been in the BIOS, it shows all 12, but task manager and cpu-z only shows 6. I would like to get as much of my RAM working as possible and have tried everything I could find, googling for similar problems, checking forums etc.
Already reseated, checked BIOS, pins are fine, win8.1 64bit.
yes 4gb (2x2gb) means you get 2 2gb sticks in each pack, each stick is 2gb, each kit is 4gb. Ram doesn't really use power, so there is no way that adding 1 more stick will be too much power for you computer to use, or you are going to have major issues later anyway. Make sure you put the sticks from the same kits in slots 1/3 and 2/4, don't try to put the same kits beside eachother. You can try rasing DramV .1v and see if that clears anything up. sometimes when you mix kits you need to add a little voltage.
