Well there is no way the board will work. It physically wont fit. Although it looks the same there are differences that make it unable to fit in. I tried to get past some of the problem with just not putting the mounting screw back in because it wont line up. I figured I would give it a go without the screw but then there is the step of needing to force the board past the airport slot. If you manage that you will then be confronted with the processor hold down not lining up to the holes in the board and that means not being able to mount the processor to the board. I gave up at that point and decided there is just no way to mount the 1.42 board in the 867 case with a processor. I dont believe the 1.42 processor will even work even though it is made to fit the board the board simply will not fit properly in the 867 case. So for future reference -- no the 1.42 board will not work in an 867 case.

Re: MDD problems - questions
Based on technology it seems feesable but could fry your processor. The bus speed on the 867 is 133 MHz the bus speed on the dual 1.42 is 167 MHz. This would be approximately 20% bus speed increase assuming the 867 processor is capable of running on a 167 Mhz bus this would over clock the processor by 20% this would put the processor up to 1040 Ghz. I'm more of a PC person than Macintosh and I know in a PC world for a 20% over-clock you need some really good cooling. I guess my point is I wouldn't recommend it unless you got kick butt cooling.

I am concerned as to will the computer boot/work with the 867 processor on the 1.42 board. The board does have firewire 800 but I am not really concerned about 800 as long as there is firewire. I just cant seem to find anything anywhere about the 867 and the difference in the board speed. I realize that most people wouldnt put a slower processor on a faster board but its what I have on hand. I am also concerned about the power supply. Will it work on the newer 1.42 board? I know there is a wattage difference but dont know if it should be a concern. I am thinking the additional power is for the larger processor and the firewire 800 but cant seem to find out about that either. Would the processor run at an "overclocked" condition because of the different bus speed? Any way to find out what it would be, or if it is even within the operating range. I did try cleaning the ram with no difference in results. > -- 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.

DeoxiT is a good one. Also just because the RAM works in another machine doesn't always mean it's totally good. Do you have TechTool to check with? You can also try with 1 stick and see if it runs right. Then swap slots.

MDD problems - questions
I have an 867 dual and recently it has been giving a bad ram beep either at post or randomly during use. I believe the motherboard is starting to go. The ram is just fine in another machine. I was wondering if I could swap in a motherboard from a MDD 1.42 dual and use everything from the 867 including the processor? I know there is a difference in the bus speed but do not know if that would prevent the 867 from functioning or destroy the 867 processor. I dont know if the power supply will hook up or work with the board. Can anyone shed any light on this? I have been cruising the net and various mac sites but cannot find this specific information. The reason I would prefer to use the 1.42 board is because I have it sitting here and there would be no out of pocket if I use it. I even have the ram for it. Any help/information is appreciated.
