Have you tried booting with a stick in slot 0 and a stick in slot 2 (obviously not ideal scenario, but should still work, I have done it before), leaving slot 1 open. If you get the error in this situation it could possibly be a faulty Dimm slot.
Also, have you alternated taking the sticks out to verify that they are all good?
And all your sticks are uniformly the same?
Just my 2 cents...anyone else?
