Tried that its seems the RAM is fine...Question should computer be able to boot with a stick only in bank 1 nothing in bank 0?
Yes, you should be able to run your system with a single stick in any
Question what specific settings must i set manually b/c i tried that and its not booting after placing the second stick in there?
You need to set the RAM Voltage, Speed and Timings.
Assuming you have This OCZ Reaper Kit
, set your RAM speed manually to 1066Mhz, timings to 5-5-5-18 (do not worry about any other timings, leave them on auto) and the RAM Voltage to 2.2v.
Assuming your system boots fine, test it with Memtest
If it tests fine, you can try lowering the RAM Voltage to the minimum specified 2.1v and retesting for stability.
