yeah probably just faulty RAM if they cannot run factory timings and speed

G.Skill usually make good RAM so just get an RMA done Cronos and be done with it i guess

Gigabyte can be a bit finnicky with their bioses............. and also try raising volts on the NB to +0.3 and bump RAM volts to see what happens

i was testing a rig a couple of days ago and the CPU i had was stable at 350MHz FSB (Celeron 460) on 1:2 RAM RATIO so i tested with 5-5-5-18 1T and did some 32M Superpi runs....i had to have the MCH volts at +0.3 or more can't recall and had to have RAM around 2.05v......

the strangest thing was that i could not bring the volts down and loosen the latecies to say 6-6-6-x or 7-7-7-x and get stability

but the board i have is not a normal production board so probably some weird ass going on with my board

i should have an X48T-DQ6 soon so gotta do those tests..........
