I've just bought a new G4 FW800 1.25GHz DP and a Digi001. The G4 came with 256MB installed. I tried to install a new DDR PC2700 (333Mhz bus) 512MB SDRAM and I'm having trouble. When I boot the G4 it's just dead. The monitor doesn't come on, the HD doesn't kick in, an occasional whirring sound from the G4. I've tried the SDRAM in each of the available DIMM slots. I've also tried it by itself without the Apple 256M RAM. When I remove it everything's OK. The SDRAM is from OWC in the States and is guaranteed to be better than Apple's specs. I even removed my Digi001 card and tried the new SDRAM in every possible combination as above, but no good.
I've got a nastly feeling that it's the SDRAM. Anybody else have similar probs? This post has been edited by lepetitmartien: Wed 26 Mar 2003, 04:58 -------------------- claudio (composer)

Looks like (I change my whole answer as your description is much more helpful for debugging now) your RAM is either not compatible, or screwed.
Get it back to the shop! Now! It may be better than Apple specs, but at least it doesn't follow them enough to work.
