Get a new heatsink. Socket A types seem to work well, or you could take yours with you to match the shape.

I found a jumper table for speed settings on NewerTech ZIFs. I'm going to try and work in the PowerForce results I found above and see if they match.
[in B&W] set at 6 / 550 Mhz / set it at 7 it did not boot / set it at 5 / 650 For B/W G3: 6=550, 2=500for Beige G3: 7=500, C=533

erm... no pattern :?:
only seeing that its the jumper settings are the same as the DIP switches on my G3/500 😉 - afair.
mine too wont boot at what i guess is 600mhz 😉

There are 16 (4^2, hex10, 1111 binary) positions on the dial and four jumper positions. From that I guessed that the dial is a four pole switch, with the hex numbers corresponding to a four digit binary representation of the on-off state of four jumper switches.
So if you make the following changes to the table: read right-to-left rather than left-to-right, and make 0 = jumper and 1 = no jumper (which would make sense if they were normally-closed {NC} switches) ...
LSBMSB MSBLSB Invert base10 Dial
========================================================
| - | | | | - | 0 0 1 0 0+0+2+0 = 2
| - - | | - - | 0 1 1 0 0+4+2+0 = 6
- - - | | - - - 0 1 1 1 0+4+2+1 = 7
| | - - - - | | 1 1 0 0 8+4+0+0 = 12 (=C)
========================================================
| = jumper 0 = jumper
- = no jumper 1 = no jumper Or does no-one do sense- and endian- reversed binary to hex conversions in their head anymore?
Bah, kids these days. Get off my lawn.

ZIF / trim dial with numbers / speed setting / PowerForce by PowerLogix / positive match. I have a 500MHz G4 that is just like that. I just kept turning the dial until the system profiler reported a speed of 500MHz. It's running in my 8500 with a ZIF Carrier card.
Temetka: any chance you could pop the top and check what the dial is set to?

I've just never seen one of those pad things before and the heatsink wobbles without it. I tried putting a little bit of extra bend in the clamp so it would hold it more firmly, but it still seems to be pushing down in the wrong spot... It holds the heatsink at a slight angle at the contact point of the processor. You might have the clip on backwards. If you look closely you'll see that the lowest point is not exactly in the centre. That point is meant to sit exactly above the CPU die. Try reversing it.
If it doesn't seem to be applying enough pressure after your bending, I'd suggest shimming it up with something metallic between the clip and the heatsink. Whatever you put in there should be conductive and firmly held down by the clip so it doesn't move. The heatsink is meant to be pretty firmly held down by the clip; ie it should be difficult but not impossible to get the clip off and on.

hmmm...
is there a way to set these ZIFs to a 9.0 or 9.5 cpu/bus ratio?
i need these because i want to play around with the ZIF in my 9600 on a ZIF carrier.
the setting of the ZIF itself isnt overidden by the setting of the ZIF carrier.

hey, this is funkymonkeypie, I have one of those PowerLogix G4 ZIF CPUs with the dial on it, the fastest i could get it go in a Mac G3 blue and white is 650 Mhz with the full 100 Mhz bus speed, i tried all combos of different dial settings and bus speeds. I think that the limit is the cache speed on the cpu, I remember getting it to boot a couple of times at a higher speed than 650Mhz by dropping the cache speed with CPU director but it was totaly unstable.
Still running great after a year, I put a 80mm fan on the heatsink to be safe, offset slightly towards the case hinge to clear the optical drive housing, powered off the same leads that run the case fan.
I picked this upgrade because there was no need to install any cache enablers for it, i hate having tu rely on manufacturers to provide legacy drivers, or updates for new OS's.

Hey great! That's one of the unconfirmed predicted settings from my list. If I'm not insane, your dial should be on 5. Is that right?
And if my calculations are correct, Temetka's should be on 9, for a bus multiplier of 10x

Just thought I'd let you know, the G4/400 (7400) I bought from IC-China is pretty well confirmed DOA. I tried it in the ZIF card and it didn't work but assumed it was the ZIF card being fussy. I tried it in the B&W today prior to donating it to a friend and it wouldn't boot in that either. I suspect it's fragged. It looks like it was originally fitted by someone with a rather too generous hand with the Arctic Silver. It was COATED in it. Either way it doesn't work 🙁

Darn shame there Mark. At least you're not out a huge wad of cash for it.
hmmm...is there a way to set these ZIFs to a 9.0 or 9.5 cpu/bus ratio? It's not documented anywhere I've been able to find, but from the table above, there's only /edit/ four undocumented settings: Powerforce dial 0, 3, D (13) and F (15). They would correspond to:
NB THESE NUMBERS ARE UNTESTED except as noted above.
===============================================
x Bus speed NewerTech PowerForce
Mult 66 100 Jumpers Dial
===============================================
?? | | | | 0
?? - - | | 3
?? - | - - D (13)
?? - - - - F (15) /edit/ now documented above
=============================================== /edit/ where ?? is either 8.5, 9, 9.5 or some number below 3 or above 10, or a non-functioning setting.
So far I haven't been deduced any pattern between the jumper settings and the resulting bus multiplier.

Apple patched the ROM in the blue and white when the Yikes! was released so you couldn't just plug in a G4. Best machine to try would be a Yikes! since that is probably what it came out of originally.

You need a firmware patch installed before you put the G4 into a B&W for it to work.

F on the dial of my powerlogix G4 zif boots into both osx and os9 at 600 Mhz and a 66Mhz bus speed

Posted by: Bunsen on 2008-05-11 08:17:31
Wooo! Awesome. That's one of the undocumented settings. 9x - which answers this:
is there a way to set these ZIFs to a 9.0 or 9.5 cpu/bus ratio? I'll update above with the F dial setting and the deduced, untested jumper settings.
/edit/ Welcome to the forums Mr Pie 😀 and thanks for putting your previous results up somewhere they could be found. Couldn't have got this far without you.
How'd you find us?

Posted by: SiliconValleyPirate on 2008-05-11 10:15:17
My B&W is already running a G4/500, it's been patched. I was testing the 400 to post on to a friend with another B&W.

I'm ashamed to say i googled "funkymonkyPiE" and it brought me here. I was in the middle of trying to overclock two Wallstreets that I use to run Opcode Vision sequencing software on some Studio5 MIDI interfaces that I have.
Mannaged to get a 266 to 300 and a 233 (512 cache) to 266 with charts from here:
http://www.phrax.ca/projects/OverclockPowerbookG3Wallstreet/
Overclocking an Apple G3 Series (Wallstreet) Laptop
There are links at the bottom of that page where he got his info, it is a page in french, the french guy got his charts from a japanese site that is no longer available.
My main project mac is a G3 Blue and White with;
Powerlogix G4 at 650Mhz
4 x 256 Ram (CL-2)
ATI 7000 Video card (not flashed)
Sonnet tempo Trio ATA-133 / USB 2.0 / Firewire
M-Audio Delta 1010LT Audio Card (10 channel)
Belkin F5D 7001 Wireless G+ card (airport extreme)
Griffin Modem to serial Adapter
Pioneer 111 DVD/RW Drive
21" Studio Display
I have an Nvidia 5500 PCI card in a PC that is on a deathwatch that I'll flash over to mac to complete the project.
Not sure if this is useful but i found a site with ALL the Apple service manuals from the 8500 and newer.
http://node123.cit.geneseo.edu/~stratton/ServiceManuals/
Index of /~stratton/ServiceManuals
My project this week is to brute force an install of Leopard on the BandW, I know its not possible with the official release but i have seen reports that the orriginal developers release had the drivers for and installed on a Yikes with an ATI 7000. So i am going to first try installing that then Pacifisizing the official 10.5 release on top of that in the hopes that the developer drivers stick.

hmmm... thx bunsen for figureing out the 9.0 and 9.5 settings.
Im running the 9600 @ 530/53 with 10x now. its solid as a rock. 😀
