Hey guys,

I have an AsRock M3A770DE motherboard with 2x2GB Ram -> basically 2 of these http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Can I add 4 more GB ram? (and does it have to be 2x2GB or can it be 1x4GB? Also, does it have to be the same exact RAM or can I buy different model of the RAM but same company?
I was looking at -> http://www.newegg.com/Product/Product.aspx?SID=u0t30318... to add to my 2x2GB

So overall I would have 4x2GB RAM but 2 different models of 2. The Tracer (the one I want to buy) and the original BallistiX (the one I have) have the same exact cas latency, volts and timings. I was just worried if I had to have the same exact 2gb ram model

It is best to have a matched set of ram. But if the ram is compatitable with each other then it should not be a problem. I have mixed ram and no problems.

You'll be fine with that mix, although as Al said, you should try and match if you can

I would but the ones I have are $80 for 2x2gb and these were on sale so I wanted to get them :p 

Will I have to do any timing changes in the BIOS or will they work as soon as I put them in?

if your ram settings are on auto then yes, bios will sort it all out to run at the speed of the slower rated sticks,
