PC not detecting RAM

[Gauzl]

I have two 4GB sticks of corsair vengeance memory on a z87 sabertooth motherboard and just recently I noticed my PC is only detecting one 4GB stick instead of two. According to the motherboard manual both sticks are in the correct DIM slots, anyone know why this could be happening?

you might be running a 32 bit operating system which can't even utilize one 4 gig to it's full potential.

I am using windows 7 ultimate 64bit, like I said this only recently started happening

Check to see if you can see 8gb in the bios. If you can't, probably a faulty stick of ram.

 

edit - try the other 2 dimm slots also.

hmm, check your bios, if it only shows 4 gig there, one of your chips got hurt or smth, try each individually and see which one boots your system and which one doesn't.

And give memtest a shot when you get the chance, won't hurt to try.

After playing around with them i realised one just wasnt inserted properly from last time i worked on my PC and only just noticed moments ago.

The other stick might be dead.........anyways try the other free slots and see if it will detect !
