I recently acquired a very nice last-gen G5 Power Mac with a dual-core 2 GHz processor. It was in perfect running condition, with 5 GB of RAM (2 x 512 MB in the center slots, 4 x 1 GB in the next two pairs of slots. All RAM matched, and the G5 passed a couple of runs of the Apple Service Diagnostic OS and EFI tests with nary a problem. It also passed AppleJack's Memtest. It had never been cleaned inside, and therefore was super-loaded with dust bunnies and dust farms. So I did the sensible thing and cleaned it out, taking the usual static electricity precautions. The RAM sticks were coated with dust, so I pulled them to clean them. I then decided to add two more 512 MB sticks to fill all slots for 6 GB of RAM. Yep, wait for it ... BIG MISTAKE! Before booting for the first time, I even checked the PRAM battery for proper voltage (good to go) and hit the cuda reset button. Pushed the power button and ... nada, zilch, nothing. Pulled the power plug and let it chill out for about 15 minutes. Plugged in and pushed the power button. Three beeps and flashing lights. Pulled all the RAM and tried just the original 512 MB pair. It chimed and booted. Many, many, many beeps, flashes, chimes and very sore finger tips later, I finally got it to boot and run properly with the original 512 MB pair, one of the original 1 GB pair, a new 256 MB pair, and a new 1GB pair, for a total of 5.5 GB of RAM. I couldn't get one of the original 1 GB pair to be recognized again, even though they had passed all those tests earlier. In fact, when I put them in with other sticks, the G5 wouldn't start. However, if I put them in by themselves, the G5 would chime and boot. Hunh? Based on what I've experienced with this G5 as well as with others, and what I've read and heard, G5 RAM sticks/slots are nothing but a bag of hurt waiting to ruin your day if you so much as even think about fixing what ain't broke. YMMV, of course. :^) Jim Scott -- -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
