I read in another G3-G5 thread that someone suggests switching to  
individual jumpers (like the ones found on the ATA and older SCSI  
drives ???), in lieu of the Jumper Block encasing the smaller, wire  
only, jumpers.

I would worry about them falling off, but that might be a suitable  
alternative if you cannot find the metal replacement ones for the  
block ... let us know what you find.

So far, my Yikes! is still behaving great after a week or so of  
moderate use.

Now wondering about going to 500 ...

Starting another thread about adding cpu fans.

Individual jumpers may have been the problem; I used a mixture of individual 
jumpers that were laying around and think some may have been the wrong size to 
make the proper contacts.

Xlr8yourmac.com has a number of articles for upgrading to a G4 Zif and 
resetting the clock speed on the Yikes! and Yosemite logic boards. One article 
recommends using Radio Shack P/N 276-1512a jumpers if the the proper jumper 
block is not available. Think I will pay RS a visit before I start this project 
again.

Thanks for the reply. --glen

 How do you obtain the temperature reading?

 Mel

XLR8 MACh Speed Control 3.4.2 provides thermal monitoring for certain  
brands of (Motorola) PowerPC G4s (750-7410), and provides a  
temperature reading (currently at 24°C).

I'm looking for more information.

You can see more about it on Daystar's site:

http://daystar-store.com/machspeedcontrol-osxandos9combo.aspx

I believe the thermal monitoring is working on my cpu (PowerPC 7400  
(Max) v2.6).

Not certain, though.

 The reason I ask is a failed attempt of trying to install a G4  
 Yikes processor in a G3 BW a year or so ago. I know the Yikes  
 board and the Yosemite board are basically the same. I was  
 attempting to over clocking the new Yikes processor from 400 to  
 450 Mhz on the Yosemite board.

 I did the firmware and the cache enabler upgraded needed to have  
 the BW recognize the G4 processor and was aware of the jumper  
 settings needed to run the newer faster processor. However, the  
 results were spotty. Either I got no boot or chime with the proper  
 jumper settings or it would run only sometimes with the old jumper  
 block as a lower clock speed. 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 ...

Any experience with XLR8 MACh Speed Control 3.4.2 (for OS X)

My room temperature is ~65 deg F, and XLR8 is telling me the cpu goes

I have a friend that has successfully over-clocked her beige g3, but with
the beige g3's there are pins you can move around to change the speed. With
a Yikes! i think that if you are only going to have to mess with the
processor and not the motherboard than go for it. But be prepared to replace
the processor if something goes wrong. OCing is risky it can totally wreck

There's a fairly simple jumper block on the Yikes! (and BW) mobo  
that is designed to be easy to change the multiplication factor that  
increases the speed.

Unlike Intels, which are eminently overclockable, early PPCs are  
usually overclockable by one step, only.

Certain G4s are just plain not overclockable, or at least not without  
running so hot that the heatsinks are too hot to touch.

I have XLR8 MACh Speed Control for OS X ... is the temp indicator valid?

I suppose if it is, I should install that, and use it to control/

It seems to work well with Sonnet G4 cpu upgrades for PowerPC 8500

 Comments? Worth the 11% increase in cpu power?

Xbench says about 12% (tested while using XLR8 MACh Speed Control  
(cpu speed 448.0, L2 cache 224.4).

Wish me luck ... temp rose from 24C to 28C.

Pushed it some with iTunes Visualizer and DVD Player.

I will be grateful and stop here.

Thanks,
