I installed some additional memory this afternoon, exactly the same make and model as the existing, upgraded from 2gb to 4gb. When i boot i now get a blank screen on the monitor and error code '05' on the LED display. I have cleared the CMOS already (using the switch on the rear) which has not made a difference.
I have tried the new memory on its own, which works fine - as does the old memory but they won't work together. I have checked votages/timings all correct.
Any ideas?
Edit: I'm using 4x1gb sticks, 3 sticks (3gb) seem to work just fine.
