Re: Overclocked MDD
According to iStat pro I'm running 2 degrees Celsius hotter at idle with both processors running. Using CHUD tools to turn on nap dropps my idle temp about 20 degrees C. At 1.5ghz there wasn't any problems. 1.58 is new to me so I'll be keeping an eye on the temp. If I get worried I'll see about adding an extra fan. One thing I may do anyways is pull the plastic grill off the back of the G4. It covers up a lot of the rear air holes.

Re: Overclocked MDD
I tried the first one without luck but I was a bit tired and may have made an error. I'll try again in a day or two when I"m more rested Wayne On Mar 6, 11:30 pm, Kris Tilford wrote: > I just realized your MDD is dual-CPU.

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 "nvstore" 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.
