Re: G5 Quad Core Shaken Up in Transport
What's the chance that the following (basically, deep clean the machine) might solve the high temperature problem? It's what I would do next. Also reapply the thermal paste, and then run ASD thermal calibration to make sure it's properly reset. I'm sorry this hasn't been stressed enough. Coolant leakage and low coolant is a common problem with these systems. This is STRONGLY indicated by the temperature readings on one CPU and by the temperature at shutdown. One CPU reading is FAR too hot, the other is far too cool. Something is definitely wrong with the cooling system or the temperature diodes. The quad G5 has a much lower rate of LCS failure or compromise than other liquid cooled G5s. If it were, say, a dual 2.5 like my folks', I agree I'd check the LCS first. But on this quad, I'd do the clean-up and thermal paste renewal first because you'll have to do it anyway, and it's more likely to be the issue. For relative failure rates, see this handy table: http://www.macintouch.com/reliability/pmg5.html Of the three quad G5s I have personally owned, none of them had an LCS issue. The one that's dead fried its logic board for some other reason, and the other two are still going strong. -- personal: http://www.cameronkaiser.com/ -- Cameron Kaiser * Floodgap Systems * www.floodgap.com * ckai...@floodgap.com -- My Pink Floyd code: v1.2a s BO 1/0/pw tinG 0? 0 Relics 2 8 6mar98 -- 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.

Wish I felt comfortable trying reseating the cpu with new thermal paste ... given the chance - I wouldn't mind trying. But I am sending it back for a refund. It's a bit over my level of expertise gained by changing a mobo in my QS 2002 Dual 1GHz a few years ago ... now my cpu needs changing, if I could find one ... Money is also a factor ... I had to borrow the funds thinking I didn't want to miss such a good deal ... it was worth a try. although I paid too much for it. A friend just suggested I consider a 1st or 2nd generation Mac Pro. I just might take him up on the idea ... and try moving my software into the Intel world, 1 expensive chunk at a time. Then I could keep up with the later generation OS Xs, if I wanted to, and have a cooler running machine. Thanks for all the great information. -- 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.

Just because you were disappointed, it doesn't mean G5s are usually that troublesome (for used hardware, anyway ;-). I've been using a G5 DP 2.7 GHz (with Delphi liquid cooling system), and it's a beautiful machine, fast and silent. Knocking on wood, I had it for 18 months and I hadn't a single problem (well, I had issues burning DVDs, but that due to Toast and not the hardware). Sure, a Mac Pro would be faster, more compatible with recent OSX, and sucking less power. On the other hand, you would have the added trouble of your old software compatibility... -- 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.

I agree with Valter. The upgrade cost can be sizeable. Part of what keeps me on 10.4 is that I have Photoshop 7 (the last non-activated Photoshop), which does not work on 10.5, and many Classic apps I paid considerable money for back in the day such as QuarkXPress. Not only would I incur the cost of the new machine, but the headaches of the new software and the costs of buying it. At least I have an academic discount, but still, not cheap. -- personal: http://www.cameronkaiser.com/ -- Cameron Kaiser * Floodgap Systems * www.floodgap.com * ckai...@floodgap.com -- I see nothing!

If you hear of any, like the air-cooled ones in the PCIs class, let me know. I believe they are air-cooled ... the 2.3GHz has been mainly of interest. Close to Lynchburg, VA where I might pick it up ... haha. If needed, I think I can buy a PCIe to PCI adapter? -- 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.

I think I would pull the CPU heatsink cover and see if the heatsink(s?) are loose with _very_ gentle side to side and up and down tugging. However, having just looked at this web page about disassembling a quad core heatsink http://www.xlr8yourmac.com/systems/G5_CoolantLeak_Repair/G5_CoolantLeak_Repair_p1.html#storytop , it is indeed more involved than my teardowns and rebuilds on my G5. However, if Bill can replace a motherboard or CPU and heatsink, he should be able to do this, with research on the web. I do urge you, Bill, the same as others here, to give it one last try before you give up on the G5. The Mac Pros have their own problems. Not that they are bad, just a different kettle of the same fish.
