New Build, Best memory?

is use 2 x 2gb corsair domitator gt 7 7 7 20 1.65v timings but yiu ahve to set it up in bios manually
these are rated at 1600 speed there fine in ga-790fxta-ud5 amd 965 c3 125 watt coasiar h50-1 works fine

Thanks Andy, I ended up getting 8 gigs of G Skill Ripjaws, they did need tweaking in bios, I have the system overclocked to 3.97 Ghz with the H50-1 running stable, can't break the 4.0 mark without stability issues, thinking might be the voltage but am unable to change it. Such is life. Temps run mid 50's at full load after 4 hours. The H50 is twin fanned---push pull That was my first foray into liquid cooling, seeing the advantages of liquid I will probably make a full water cooling attempt next winter as a cold weather project
