2GB 1333 + 4gb 1600mhz will work ?

[soberguy]

Hey
I have ASUS p7h55-v mobo , currently I have Transcend 2gb 1333 RAM.
Can I use Corsair 4gb 1600 RAM with the above mentioned RAM. (2+4= 6 gb RAM total)
Will both RAMs work without issues.
regards

sadly you cannot, these two types work on different voltages. (1.5 & 1.65V).
even if they are both DDR3 with CL9.
there are general rules to mix rams, here: http://www.lifehacker.com.au/2010/07/what-are-the-rules-on-mixing-two-different-types-of-ram/
so get these new 4G rams, then get other 4GB in the future if you cannot buy it now.

UPDATE: even if you find a new RAM that can be mixed with the old one, this new ram will be downclocked to 1333MHz anyway.
