Something about overclocking and temperature that is a bit difficult to find information on: Faster processors typically use a phase locked loop internally to multiply the applied clock frequency by a small integer - less than 100. I donno about G3 and G4 but anything running over a GHz internal is that way. It's just too hard to deliver a GHz clock to a pin on the circuit board. They also contain internal temperature sensors that can have microcode access that allows for changing the multiplying integer. When the chip gets too hot it can be automatically slowed down without telling you about it. The external clock, the one you're mucking with using changed components need not change at all. When you ask software a question like what is my frequency? you really need to find a standard clock somewhere that can be used for comparison. Options are things like GPS, WWV, a rubidium standard you purchase for more than you paid for the computer. Otherwise the computer will assume the comparison is to be made from what it thinks is its clock frequency.

Re: Overclocked MDD
I have used those blue ice packs to cool my computers many of times as a temp fix, till you can figure out a better method. I would hang it close to the fan so it blows the cool air in it, I also have used them to sit my Tibook on when the fan went bad till I fixed that too!!! -Original Message- From: Jesse St.John jesselorenstj...@gmail.com Sent: Mar 7, 2012 1:38 PM To: g3-5-list@googlegroups.com Subject: Re: Overclocked MDD how are you effectively cooling these as my mdd runs relatively hot already? and i would lke to do this but i am a chicken and i dont want to ruin a good thing. i witnessed online a gentlemen who showed me the resistors on the cpu chip itself to adjust, but decided not to do it until i had one myslef to try out.

The line in the patch dev PowerPC,G4@0 would likely need an additional CPU which I'd guess would probably be identified as G4@1? I don't know the nuances of Open Firmware, so it's possible the solution for dual CPUs could be as simple as appending G4@1 to the dev PowerPC,G4@0 like this dev PowerPC,G4@0,G4@1? Since I don't know the real answer for dual CPUs I think that the simplest solution would be to enter the entire patch TWICE, once for G4@0 and once for G4@1 in the line dev PowerPC,G4@0. If you want to do this in a single operation without an intermediate reboot, you could enter up to step #5 nvstoreReturn for G4@0 and then repeat from step #1 again for G4@1 and only after the 2nd step #5 proceed to #6 #7 which tell the Mac to use these alternate stored versions and reboot. It's possible you may need to read up on Open Firmware commands for this dual CPU patch to work correctly, but it should be possible. -- 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: HD problem on my PowerMac G3
Thank you all for your input. I decided to format the drive and start fresh, as the PowerMac G3 came with the HD drive and Mac OS 8.6 installed from previous owner. I tried to boot up with original Mac OS 8.6 disk in DVD drive holding the 'C' key, and it would go straight to the HD. My guess is that the original disk is not a boot up disk, but how can I start fresh? Any ideas? On Mar 5, 2012, at 6:46 PM, Douglas Mencken wrote: Is there a problem with Mac OS 8,6 handling data??

AGP Video Card Selection
Would someone suggest a good agp video card, available today, that I can use in my Quicksilver Dual 1GHz under 10.5.8? I want to purchase a Samsung 22 HDTV for use as a monitor, and it requires HDMI input. Perhaps a video card with a DVI connector, as I have an extra DVI to HDMI adapter. I guess the key phrase is available today ... not sure about where they are being sold these days, reasonably priced, for a G4. I currently have a Geforce 4MX in my Quicksilver, and an ATI Radeon 9800Pro in my DA Dual 533 (its DVI to HDMI is being used with a Sony Bravia from time to time). Another ATI Radeon 9800Pro is probably too much of a card for what I will be using it for ... I'm not a gamer.

MDD motherboards
Since all the smart people hang out on this list, having kept their G3 to G5 Mac computers, I thought this would be the best place to ask for help with this question I own a dual 1.25GHz G4 PowerMac MDD (FW400, not FW800), that I have upgraded to a stock Apple dual 1.42GHz G4 CPU module. My question is this: Since I now have two dual G4 CPU modules (dual 1.25GHz dual 1.42GHz G4's), I want to trade my dual 1.25GHz G4 CPU module for a single 1.25GHz G4 CPU module, to a friend of mine that owns a single 1.25GHz G4 PowerMac MDD. Then I want to look into the possibility of over-clocking the single 1.25GHz to 1.33GHz, 1.5GHz, or if possible, 1.67GHz. Are all G4 CPU modules for the G4 PowerMac MDD computers interchangeable (including single and dual G4 models), or in other words, are all of the motherboards (except the FW 800 model) the same? Here are the reasons for this strange question; 1. The G4 PowerMac MDD is a very noisy computer 2. To make it quieter, the fan must be replaced with a quieter version, which is going to push less CFM's. 3. If I am going to use this G4 MDD to run an OS that is not SMP capable, I don't need the 2nd G4 CPU one way to reduce heat, would be to use only one G4 CPU. 4. The single G4 CPU will be okay with the lower CFM's of the quieter fan. 5. Using only one G4 CPU will give me greater flexibility to attempt over-clocking, while still producing less heat than the dual G4 CPU modules. Since I have many other G4 and G5 Mac computers to run MacOSX and MacOS9 on, repurposing this one Mac for running only an alternative OS won't hurt my ability to run MacOSX MacOS9 whenever I need/want to.

Re: MDD motherboards
You can easily swap CPU modules between MDDs with the same bus speed. You can also do it between MDDs with different bus speeds but you need to do some resistor mods to get the best results or in some cases to work at all Taking out a dual 1.25 and replacing it with a single 1.25 is just plug and play Your dual 1.25 will have a 2mb cache while the single will have a 1mb so a dual running on one processor should still be faster than a single. Let me throw a bizarre idea out there that no one else would likely ever want to do. The dual processors clock speeds are individually set. Why not set the unused processors clock speed to the lowest possible speed. I think that would be 333mhz On Mar 6, 8:44 pm, David W.
