Of course. Someone pointed this out to me awhile ago ... when you simply replace a PCI card, push the CUDA ... sometimes the PCI Graphics won't power up ... then you need to read this: http://docs.info.apple.com/article.html?artnum=95066 this is also of interest (CUDA part, referring you also to 95066): http://docs.info.apple.com/article.html?artnum=95065 > > The reason I ask is a failed attempt of trying to install a G4 > "Yikes" processor in a G3 B&W a year or so ago.

I just assumed the G4 Zip was defective. You did a few more steps than I did ... I never replaced the cpu ... I'm using the original G4/400 that came with my Yikes! that I recently got from a friend near Philadelphia ... I just adjusted the jumper block, as found in this article: http://www.xlr8yourmac.com/G4ZONE/G4YIKESOC/index.html > > Now from your post, I 'm thinking the jumper shunts I used may not > have been connecting properly. They are so tiny, aren't they? The one I put into slot 4 was bent slightly too tight on the inside middle area ... so after looking at the others that I didn't mess with (5,6,7 ...), they were all nicely shaped ... so I tried to reshape the one I had moved from 3 to 4. That left 1, 2, 3 empty, 4 re-shaped and the rest untouched. I would suggest finding a source for new jumpers ... and using them. The ones you take out are easily bent out of shape. I had to create a tool to hook them and pull them out ... a simple straight pin that I put a tiny bent hook shape on the sharp tip ... The first one I took out (slot 1) flew across the room, and when I finally found it, it was missing an inner prong ... The one I took out of 3 came out better (practice makes for progress). Was going to give up when I thought about looking at them all under a magnifying glass again ... and trying the copying of the other's shape idea ... after all ... if that didn't work, I was at a loss ... since I had messed up the first one ... At 3:00 am or so ... patience and slight of hand ... it worked. With the technique of removing the battery, waiting 10 minutes, etc ... and having properly shaped jumpers ... Chime! Still running with no freezes at 450 (448) ... or seizures, as a friend called it off list ... > > No rush on reply, the B & W in question is now in storage -- but if > I ever get the time (hopefully in the next year or so) I may try it > again. TIA --glen > > I'm considering trying 500MHz ... but would make myself install a cpu fan first ... so I probably should stop here. Feel lucky I got it to work at 450 and, it also seems stable. Oh ... I'm using XLR8 MACh Speed Control 3.4.2 under OS X Tiger to control/monitor the cpu and L2 cache. Maybe that's another factor you might consider? It works on non-upgrade type cpus, as well as the upgrades, and it appears to have come about when the G3s and early G4s were making their debut ... i.e. the Yikes! single cpu era. Whew! One cup of coffee and some cookies ... and I'm off! Then there's this new (2nd hand) Apple Aluminum KB and Mighty Mouse I wanted to get to know better ...
