I'm looking to upgrade the RAM on my system. At present I have 2x 4GB Corsair Vengeance 1600Mhz sticks.

I was thinking about buying 2 8GB sticks and replacing the existing RAM (using it in another, old machine I have).

What I'm wondering about is the 16GB RAM limit. Does this mean that I can only put 4GB sticks in each channel (4 channels = 16GB) or will the motherboard be perfectly happy to use 2 channels of 8GB each?

If I have to, I guess I can buy 2x4GB Corsair Vengeance 1600Mhz sticks and match my existing ram.

Well, your system supports upto 32GB of memory. The motherboard does support 8GB modules so you should be fine. You can go with 2 x 8GB module for 16GB upgrade rather than 4 x 4GB.

If you need memory then some of the links mentioned below:
http://www.crucial.com/
http://www.newegg.com/
http://www.kingston.com/us/

I'm not a big fan of bestbuy but you can give it a shot. Good luck!!

Legohouse, Werner123, thank you both for your replies. It's good to know for certain that the motherboard will handle 8GB sticks just as well as it's handling the existing 4GB sticks.

Werner123, I need the extra RAM because I moved from dual-booting between Windows and Linux to running Windows within a VM in Linux (Ubuntu, presently, as the Debian version of VirtualBox isn't the latest) and with other headless VMs running (3, 1 Ubuntu Server LTS, 1 FreeBSD and 1 Debian Squeeze) that I use to test and learn new stuff... I end up maxing out my system RAM pretty easily. 16GB should be far more than I require (I'm thinking 10-12GB is all that the existing setup needs, to run a little faster and be more stable).

When I bought the motherboard through ebuyer, I saw it listed as supporting 16GB max, but now that I've gone and checked Asus' website, I see that I was wrong. Well, that's a pleasant surprise, though I don't imagine I'll require 32GB RAM any time soon.

Legohouse, thanks for the links but my options are either to go cheap and buy 2 more sticks of 4GB Corsair Vengeance 1600Mhz RAM and use all 4 channels on the motherboard (but as Werner123 warns, this will negatively impact the RAM frequency - not sure why) or to dump the existing RAM into another machine and by 2 sticks of 8GB. I needed to make sure that the latter was a valid (motherboard supported) option, before I acted. Now thanks to the both of you, I am reassured and can make the decision.

I'm thinking of sticking with Corsair Vengeance 1600Mhz, because the existing RAM is of that make, model and frequency and it has been running perfectly fine for a year now. And so if I get 2x4GB, they should be fully compatible and not cause any problems. If I go for 2x8GB, then I might as well stick to a brand and model that I know works, and is cheaper than Crucial.
