Thanks for reading this through. Right now I have a 3x2GB kit of OCZ DDR3 PC3-12800 CAS 7 RAM. I want to get another kit, but I can't seem to find it on Newegg and most places seem to be out of stock. I have looked at Newegg further and found the kit I have to be discontinued, which is too bad. I have found this kit http://www.newegg.com/Product/Product.aspx?Item=N82E16820227365 , which is a 3x2GB DDR3 PC3-12800 CAS 8 RAM. I don't mind running both kits at CAS 8, because I may have to due to the IMC. Do you think I would have any issues running both of these kits together on my ASUS P6T motherboard. If it helps, I'm running my CPU @ 3.7GHz 195MHz x 19.
