Here are some really fast ram kits that don't cost a small fortune.
Keep in mind the PI ram is really tall 54mm and may cause HSF dimm interference now or in the future if you added more.
The Muskins are 40mm and the Corsair is 33mm low profile. http://www.newegg.com/Product/Productcompare.aspx?Submi...
I added the Redline CL6's cuz they're sweet.
