[neocon]

Building a HTPC and already have this motherboard

MSI H61I-E35 V2/W8 S1155 Intel H61 DDR3 mITX, using a Celeron 1610

Going to add 4GB of RAM, can you spec me some ram from overclockers to go in it?

Am I right in uderstanding it must be 1.5V only?

No it can be any voltage RAM.

It's a new build. I just read on MSI website it only takes 1.5 v RAM. Will only be used as a HTPC so do you think 2x2gb or 1x4gb would be better?
