I want to do a 4x1Gb dual chanel configuration.
I think you should get 2 x 2GB instead of 4 x 1GB. So you have two extra RAM slots for the future, should you ever need more than 4GB of RAM. Here's the kit I would recommend for 2 x 2GB:well i cant run any higher than 800MHz on my striker xtreme, and i have the ultra chilltec cpu heatsink and it covers 2 of my dimm slots, so i cant get any ram that has a big *** heatsink on it.

About your heatsink covering the RAM slots. Did you mean covering them, making them inaccessible? Or just hovering over? Well either way, I think 2 x 2GB is the way to go, because 4 x 1GB puts more stress on the memory controller, since all the slots are filled. Especially when overclocking.
With the latest BIOS, the Wolfdale is supported. Unless you meant issues, as in overclocking it well.aren't there issues with having a Wolfdale and a 680i?
