Question Ram compability

[cybercore]

Hi guys i have Gigabyte GA-MA-770T-UD3 motherboard with AMD Athlon(tm) II X4 645 Processor.
I got cheap offer to buy Corsair Vengeance DDR3 4 GB 1600 Mhz.
So i think to upgrade x2 of the ram slots to my pc with those Corsair Vengeance.
At the moment i have x2 Elixir DDR3 2 GB 1333 Mhz.
What you can suggest me ?

If by "upgrade x2 of the ram slots" you mean to ad 2 more of those 1600MHz sticks, all you will get is more RAM but same speed as old ones.
If you are changing old ones for new ones but same capacity, you will not see any performance gains that would matter.
In systems like that, that much faster RAM would make +/- 1% of whole system performance.

Sry its my fault i want to add 2 more 4+4 gb 1600 Mhz.
Also i forgot to ask does it will my motherboard support those x2 Corsair Vengeance DDR3 4 GB 1600 Mhz or its better 1333 Mhz.
I'm asking why here on the specifications page is written that it supports 1666 (OC).

Memory :

1. 4 x 1.5V DDR3 DIMM sockets supporting up to 16 GB of system memory (Note2)
2. Dual channel memory architecture
3. Support for DDR3 1666(OC)/1333/1066 MHz memory modules
4. Support ECC memory (Note

And does that OC mean overclock ?
Sry for the foolish question,but im noob at hardware.
