Re: G5 2.7 RAM upgrade.??
I had a similar experience with my wife's iMac G5 (2005). I bought bargain RAM online and the G5 did not recognize it. When I replaced the RAM with RAM sticks that I bought from OWC, I had no problems. If I learned anything from this it is that the brand of RAM is important. I was able to return the bargain RAM for a full refund, so the only loss was the loss of time and perspiration.

I don't like to be the bearer of (possible) bad news, but I just had a problem similar to yours (you can check the Group's archives for 3 blinks and no boot subject), on my Early 2005 G5 DP 2.7 (looks like you have the same G5). Well, in my case it seems the memory controller soldering has gone bad, thus it doesn't matter which Ram I insert (and even without Ram), it's always the 3 blinks. To prove this, I heated the memory controller area (a square of solders between the two slots blocks, on the right to them) with a hair dryer (a couple minutes), and this made the G5 boot and work for some time (15-45' usually). It seems many computers made around 2003-2005 had this oncoming problem, due to lead-free solder (Google lead-free solder g5 problem). One of the suggested trick was the hair dryer one (it makes the solders contacts temporarily working). In your case, you might have the picky Ram issue many mentioned here, or you might have an issue similar to mine. I wish you good luck. ;-) Prior to this problem, the memory controller's temperature was always high (around 75° C), thus it's likely that contributed to the subsequent failure. -- -- 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.

My G5 died when I reseated my memory because they were far to tight. It must have cracked the solder. Maybe that's what happened to you.

It is possible, but unlikely, they somehow got zapped when you were moving them around. Be sure that you are counting the right number of flashes; one means no RAM is seen at all, and two means incompatible or incorrectly installed RAM. Make sure the RAM is paired in the slots from the center going outwards. If it already is, or that doesn't fix it, try resetting the logic board. Unplug the machine for at least two minutes and retry. If this is no good, open the side, remove the front fan, and press the SMU reset button (should be at the bottom under the bottommost RAM slot). -- personal: http://www.cameronkaiser.com/ -- Cameron Kaiser * Floodgap Systems * www.floodgap.com * ckai...@floodgap.com -- if (you.canRead(this)) you.canGet(new job(!problem)); -- Seen at JavaOne --- -- -- 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.

Re: G5 2.7 RAM upgrade.??
My 2.3 dual CPU G5 is super picky about RAM. I had to reseat RAM and restart about 30x to get 4 pairs in all 8 slots to recognize simultaneously. It took hours. I got one pair to recognize, then shutdown and added a new pair until I got two pairs, then added a third pair, and finally a fourth pair. VERY frustrating experience. I haven't touched the RAM since then, a couple years ago. I've got 6GB total as 4x1GB and 4x512MB. I've now got four more 1GB sticks so I could upgrade to the 8GB max but I'm too chicken to risk the likely hassles for only 2GB extra. Someday I intend to add the extra RAM, just not now.

I'd say ... keep trying ... with crossed fingers. ^ this is what concerns me when i jump to a g5 here in a month yaaarg This should add to your stress level. 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.
