G4 533MHz ZIF - $20

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.
Heheh. Is anyone else seeing the pattern here?
Code:

- afair.
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) ...
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.

... and so from there we can fill out the rest of the table:
I'll edit and add to this table as I fill out the rest. I'll also notate which settings have been tested. When it's all finished, I'll add it to the wiki.

" 10x ratio is not supported on all G3 CPUs,
9x is the max ratio on G4 7400 CPUs in most G4 ZIF upgrades
(and all Newer Tech G4s I've seen)" ** quote by Mike on xlr8yourmac

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.
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.

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.
/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.
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:

It may still be alive. 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.Just thought I'd let you know, the G4/400 (7400) I bought from IC-China is pretty well confirmed DOA.

F on the dial of my powerlogix G4 zif boots into both osx and os9 at 600 Mhz and a 66Mhz bus speed
Wooo! Awesome. That's one of the undocumented settings. 9x - which answers this:
/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?
I'll update above with the F dial setting and the deduced, untested jumper settings.

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:

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.

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.
