See, this is the thing, a processor will run UNDER-CLOCKED better than it will OVER-CLOCKED. If I have a bootable system with a g4-450 mhz. Putting a 500 mhz processor in there without changing the jumper settings will only tell the 500 mhz processor to run at 450. Much like it tells the 400 processor that is in there to run at 450.
For grins, I put a known bad 300 mhz g3 processor in there with no jumper settings change and it booted to the blue screen before it dumped. I did get the chime and video. So I really suspect this chip is bad even though the guy "swears" it came from a running system. Well, I bought a keyboard and mouse (apple brand) 10 days ago on ebay. I have sent the guy mail telling him his usb keyboard and mouse hasn't gotten here yet. Hopefully it is in the mail and will get here in the next day or so and I can see if the chip will reset pram and enter into open firmware. I will feel a lot better about it if it can do that. I looked on apples site to see if there were any firmware patches for the Yikes G4. I saw none for a G4 PCI computer. They were all for sawtooth and the such. There weren't any firmware hinderances in there to stop a 500 mhz chip from running in the yikes that I know about. Looking at all the upgrade sites I don't see any Yikes patches to allow a faster processor to be put in. They all seem to be plug and play. So I dunno what I am going to tell this guy. Wait for the keyboard and get more information I suppose. -- 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.
