Compatibility with F3-12800CL7D-8GBXH?

[Blizzie]

I bought a 2x4GB set of these RAM sticks a while ago but they were discontinued sometime ago. Since I need an additional 8GB, are there any sticks that are compatible with these ones without sacrificing performance?

CPU: Intel i7 2600K
Mobo: EVGA P67 FTW E679

Here's a link to the sticks:

Thanks!

Without testing two kits together, we can not be 100% certain. We can only recommend kits that are pre-matched, tested, and guaranteed from factory.
