Asrock extreme3 r.0.2 with amd FX8370 procesor it works fine with to banks of 8Gig but when placing the other 2 my computer does not boot!!
Yes they are the same, and the slots works fine because before upgrading I had 4x 2 gig in my computerIs it from the exact same kit? or bought alone? plus did you try the two ram sticks that worked on the 2 ram 2 ram slots that didnt work? if it worked then your ram could be dead.
If it didnt work then your motherboard could have dead ram slots.
YES I did and they worked fineDid you test the exact same Rams that work in those 2 slots first? if the rams didnt work in the same slots probably faulty ram, else i dont really know.
