Recommend a 2Ch D3 RAM

Hi. I plan for a new PC early August and I would like a RAM recommendation.

PhenomII X4 965 / X6 1090T
ASUS M4A88TD-V EVO/USB3
Galaxy GeForce GTX 460 1GB Super OC / Palit GeForce GTX 460 1GB Sonic Platinum / MSI GeForce GTX 460 Cyclone OC 1GB
CoolerMaster Silent Pro 500W
Crucial C300 64GB SSD
CoolerMaster Hyper N520

The brands that available in my area are Kingston, Corsair, AData, & Patriot. I want to overclock a bit maybe bring the processor up to 4+Ghz as well as a bit on the RAM. I would like a dual-channel 4GB DDR3 RAM.

What's the recommendation?

Thanks.
