I’ve recently built my new rig with the Maximus Extreme IV ( REV3B), but it won’t boot! I keep getting the ‘55’ debug code which is ‘memory not installed’ but it is!
I have tried swapping the CPU with another i5 3750k I had working in another machine
I’ve tried changing the RAM (from Corsair Dominator Platinum 2X8GB to 2 x4GB that was working in another machine) but still I get ‘55’
Has anyone got any ideas?
Does Corsair Dominator Platinum even work on this motherboard?
If not, has anyone got any suggestions on which 2x8GB I should get?

Any help would be gratefully received!smile.gif
