Hi Folks,
I've owned a G4 MDD DP 1.0GHz for a while now (one of the models that can boot into OS9) and I've always wanted to upgrade the processor with the DP 1.25GHz and overclock it to 1.5GHz.
Anyway, the opportunity to buy an MDD with the DP 1.42GHz (FW 800) came up and I jumped at it as I thought I could simply overclock it to 1.5GHz and put it (plus the copper heatsink!) into my older DP 1.0GHz machine.
So... I overclocked the 1.42GHz to 1.5GHz and it tested fine in the FW800 tower. But when I took it out and put it in my older machine (the 1.0GHz tower), the computer wouldn't boot.
I tried fitting the processor card several times (thinking that maybe I hadn't seated the card properly) but each time the machine didn't boot.
Both MDDs - the DP 1.42 GHz and DP 1.0 GHz - have the same System Bus Speed (167Mhz), so I thought the processor cards would be compatible.
Has anyone tried the above? Do the cards from the FW800 MDDs work in the earlier models that can boot to OS9?
Many thanks
