Hello every one, I just bought myself a couple toys and I am having a problem. My set up : i5 2500K P67 Asrock Extreme 4 G.Skill Ripjaws : My Ram < - That is my RAM 6950 with MOST up to date graphics and a 750GB Seagate something.. lol its a 7200RPM... but my problem is : 1) I am trying to get my RAM In duel channel... every time and I mean EVERY TIME!!! (yes every time lol) I get a error code of 55 on the debug LED = no ram installed (this says it on the user manual) 2) I have tried every slot with both pairs.... One DIM at a time... Well all RAM slots work perfectly fine. And it boots up perfectly no problem ONLY and ONLY IF I do not run the memory in dual channel. 3) So now I have a 8GB of RAM running in single channel and it is annoying but not a game breaker though. Any help will be very helpful. I know a lot of people have this board I just need help on getting this quirk solved.
