Hi there,

I currently have a MSI Z77A-G43 motherboard and 4gb of Corsair Vengeance LP 1600mhz Cas9 ram module (originally came in a dual kit, but one was faulty). I am looking to upgrade and have recently bought an 8gb of Corsair Vengeance LP 1600mhz Cas10 module.

My question is, should I completely replace the 4gb module with the 8gb, or is it possible to have them both, giving me 12gb total ram?

Your help is greatly appreciated!

Stick em in together! Because of the different size, you will get a single channel config and the bios will choose the higher latency, but i you will end up with 12GB - assuming you have a 64-bit OS.
