I've been running my system with 3x2GB of ram http://www.newegg.com/Product/Product.aspx?Item=N82E168... . The motherboard has 4 slots for ram 2 are independent channels and the other 2 are part of the same channel. So i decided to get a 4GB ram upgrade and bought this http://www.newegg.com/Product/Product.aspx?Item=N82E168... . I haven't been able to find a successful configuration using all 10 Gigs of RAM. I seems any time I try to occupy the second slot of the third channel it has a POST test failure. Right now I have the 4GB in the fist channel 2GB in the second and 1 2GB in the third, but if I try to put the last 2GBs in the third I can't boot into Windows. Even though everything seems fine in the BIOS.
