The heat sink cover is locked on by a plastic rivit of sorts you must artfully dig out with an exacto knife and a wood screw before removing the heat sink cover. These processors can be known to come loose over time with the natural vibrations of use and I've fixed a few of them by just reseating the processors. I'd try to reseat and then recalibrate the processors before going off and purchasing a new set of processors.
"630-4890") or "T4838" (from the auction listed in my 1st post) need to match?. Where might I find a chart, (or does someone know) which numbers (i.e. What is the LIMIT of compatible processors? (mine is a June 2004 model w/PCI-X slots). I've learned that since both processors sit on the same board, and the designs didn't change that much, I have more leeway (as long as it's a firewire 400).Īm I right in suspecting that with all the changes in the G5 line, I need to stuck much more closely to the "identical" numbers, as in the auction above, or can I replace both with a set from say. I.e I have a MDD dual 1.25 (firewire 400) with a fried processor. Would that give me greater leeway in the selection of compatible models.? What if I see an auction for a set of TWO? But are they two of the same, or reversed (mirrored) in design? I'm guessing that it must be pretty close to "a mate" for the remaining processor. "Processor A" MUST be replaced by a "Processor A". Hard to tell until I open it up and look for similar numbers on my machine.ĭo we have any deep thinkers out there who know what range or variance (if any), is allowed in replacing only one of two processors?Īlso, are they the same, or are they "mirrors" i.e. In the example above (the ebay auction), the seller seems to be denoting a family possibly and maybe a motherboard model. Which family (or series) of processors do I need to choose from? So we're back to the question buried in the middle of my original post. then shifts the load back to "Processor A". The computer seems to labor a bit, as if it searches for processor B by default. I never noticed the fans spinning up much at all before, unless under heavy load. What concerns me then, is the fact that the fans (or one of the rear case fans) case fans spins up (approx 25% faster) for 4 seconds then drops to "normal", more often. Temp sensor shows CPU A Die Temperature 134º FĬPU B Die Temperature "This sensor is no longer connected" I just check the profiler and this is what it shows. I've never encountered anything like this. I don't want to tear off the wrong thing, but I can't see obvious way to get at the CPUs.

I don't even know how to open the G5 processor/heat-sink "cover" to get a look. Where do I find the numbers on my system to match the above?Īre these the actual processor model numbers, motherboard numbers and/or the computer model numbers?
"2GHz Apple Power Mac G5 CPU Processor 630-4890 / T4838" How close a match does a replacement CPU (ebay etc) have to be?įor instance, on ebay I just found a single G5 2.0 (from a dual 2.0 system, and the description says this: Will running in this state until I can replace the CPU damage the computer? a dual 2.0 actually runs on only one of the CPU's? How can I tell if what I didn't think was possible. I'm attaching the panic log, if anyone can decipher what it means. I finally restarted & I'm using the computer right now. Is it even possible for a dual G5 to run in such a state? Where it normally shows two "frames" representing the two processors activity, I wanted to see what was going on so I opened the activity monitor. I checked the startup drive from the utility.

I went away for 30 minutes & found the machine frozen with the main fans running full blast. I bought a dual 2.0Ghz G5 about a month ago.
