what's wrong with my mpc 1K?

after i installed a kind of 256MB RAM , the mpc checked it when the power was switched on , then the problem was shown

since it started up and some of the tests passed that probably means you installed it correctly

my guess is a faulty memory stick. maybe you fried it with static electricity when installing it.

try taking it out and make sure the mpc starts up without it

dude, the MPC is telling you exactly what the problem is and how to solve it right on the screen... you newbs never stop amazing me.
