I just bought 32GB (4x8GB) Corsair Vengeance RAM to go in my custom build and noticed that my computer has virtually ground to a halt. At first I thought it was bad memory, but if I just put in 2 sticks then everything works fine. Then if I swap with the other 2 sticks, everything is still fine, it's just when I have all 4 sticks in that everything grinds to a halt.
Am I missing something obvious? I was hoping to have 32GB in for some VMs so I can learn some SharePoint development, but I'm not particularly happy that I can only use half the RAM I bought.
I have no idea what revision of the motherboard I'm running, nor do I know what version of the BIOS I've got (or if it's meant to make a difference).
Any suggestions would be welcome.
My build is:
32GB Corsair Vengeance RAM
OCZ Vertex 3 120GB
Corsair 750W CMPSU-750TXV2 PSU
OK, so I've tried using both channels (I think, since I'm quite new at this stuff). I tried putting a pair of simms into slots 1 & 3, and slots 2 & 4, and everything works fine.
I then tried putting all 4 in, and choosing "Load Fail-Safe Settings" in my BIOS and it still was running badly. Just to clarify, it takes about 5 seconds to boot Windows 8 with the 2 simms, but about 3 minutes with the 4 simms.
I'm guessing I might be stuck with the incompatible RAM This is the type I bought: http://www.scan.co.uk/products/32gb-(4x8gb)-corsair-ddr3-vengeance-lp-jet-black-pc3-12800-(1600)-non-ecc-unbuffered-cas-10-10-10-27
Doesn't look like my supplier stocks the Crucial RAM, so I might be stuck the excess.
