2nd kit of RAM same brand or not?

[ale86cuba]

hi there,
I have a system with the following ram
http://ncix.com/products/?sku=27537&vpn=F2-6400CL4D-4GBPK&manufacture=G.Skill
now I want to buy another 4gb kit, can i buy it from a different brand but with the same speed and timings? Will it make a difference or will they all work the same as if it was all Gskill?
thanks

It's better to run the same brand as there "should be less issues" with compatibility. That said I have run many kits together. As long as they are the same speed, timings, and voltage, you should have no real issues running different kits together. You may however need to raise the NB volts to allow for the 8GB of ram to run stable

North Bridge voltage will be in the MIT section under the voltage selection. Not positive on what its labeled, I would assume its labeled North Bridge or MCH Voltage.
