I already have 1x2 gb 800 mhz in it, but im am not sure what it is. Does it matter if latencies are different or brands?

thanks

 

Googling shows that module is PC2-6400 SODIMM 2GB CL6.

And different latency, timings, frequency, brand, etc doen't matter. The faster module will downclock to match the specs of the slower module.

 

In a perfect world, and admittedly most of the time, this is correct. ?However you should always try to buy the same speed and latency RAM that you have already installed, preferably the same brand if you can. Not saying it won't and you should be fine with Kingston, Crucial, Patriot but there are some major brands of SODIMM that don't work in CLEVO chassis.

Best thing to do is to download CPU-Z http://www.cpuid.com/cpuz.php and buy RAM the same speed and latency.
