I just checked on my own P3 what happens with each of the RAM ICs
removed in turn.
When I took out U3 (the left hand RAM), I get the same pattern of
colours as you have.
Try swapping RAM U2 and U3 - the behaviour will be different depending
on which socket a dud RAM is in.

I'm uploading a new firmware version shortly that includes a RAM test at
boot that will tell you if either RAM is not working.

Cheers,
