iMac G5 & Crucial 1 gig RAM stick

[vinylbomb]

I just purchased a stick of after-sales RAm from Crucial.com. On receiving it I eagerly stuck it into one of the DIMM slots on my original iMac g5, rebooted (slower than usual), had a look at my system, and saw the RAM was................not there.

The "about this mac" tab only recognises 256 megs of RAM (the original stick) and not the new one.It should say 1.25. The RAM is guaranteed compatible from Crucial (I used the memory selector tool to pick it out), and just wont appear.

Anyone know of any probs like this? I'm pulling my hair out here, dont want to return the RAM but I dont think I'll have much choice if I cant find a fix.

Can you turn it off, swap the ram dimms in the slots, then reboot?

I had this happen to me once, it was just me being dumb - the ram wasn't seated correctly. Just double check that it's in all the way, to rule out the easy problem.

unfortunately I've tried swapping 'em over into different slots, and I've used as much force as I think I can in seating the RAM into the slots (so I'm certain its in OK) but still getting nowt from it
