having some trouble with trying to boot my rig with the 800mhz ram i have (teamgroup xtreem pc6400) have tried the 4 sticks in the first slot on the board but all i get is error codes eg c1 and 25. borrowed some old pc2 5300 5,5,5,12 1.8v, from a mate and the system works fine. what i find strange is that the team ram should boot ok at 1.8v 5,5,5,18 before being set to its proper volts and timings. anyone have any suggestions. thanks in advance
