G4 533MHz ZIF - $20
Ebay seller IC-China has just listed a stack of new ZIFs; some G4s and some G3s. Have a look in their shop under Chips->IBM and ->Motorola.
I just scored a G4 533 for $20, so help yourselves to what's left }
The ones with 750 in the serial number are G3s and the ones with 74-- are G4s.
I've always found them a reliable seller.

I look at that feller's site every day, the most recent look being at about 0730 today, and damme if he didn't list just afterwards. I agree about his reliability, in quality, price and promptness. Even the USD2 creep in G4/500 price in five months is chicken-poo.

In or near the header of most eBay pages (whatever the localization), near the Search button, is the text 'Advanced Search'. Click it, and then select Items by Seller in the left-hand panel of 'Search: Find Items'. You can enter the exact eBay ID of a target seller, or an approximation of the ID, in the left-hand panel of 'Search: Items by Seller'. The approximation will get you a list of possible targets on which to search or to home in on.

I have XLR8 ZIF G4/500MHz upgrades in my Beige G3 DT and MT, but I stick with G3 ZIFs in my 7300, 9650 and 9600 (née an 8600). My suspicion is that the graphics capability of a G4 is wasted in Beige 60x Macs. Look for the Sonnet realizations of G4 ZIF cards for the greatest stability/versatility.

While I would tend to agree with you equill with respect to the 60x Macs and G4's.
That being said I still have a 500MHz G4 in a ZIF Carrier card in my 8500. It was either that or a 233MHz G3. Now whilst either chip would make for an excellent upgrade in terms of overall performance, I went for the G4 for sheer speed and to Altivec just in case. I have noticed that the G4 really kicks in under Jaguar. In OS 9.1 I have great performance. I suspect it is mainly due to it's 500MHz clock and not the presence of Altivec.
Still a 533MHz G4 for $20 is a freakin' steal.

Then you and I differ scarcely at all. I don't put OS X on Beige 60x PPCs, but keep them in 9.2.2, for which a G3/500MHz does exceeding fine. There are, excluding my wife's G3 iBook and G4 eMac, seven machines with a native G3 or G4 in the house, running 10.2, 10.3 (five of them) and 10.4. There is neither need nor entertainment, for me, in pressganging the Beige 60x Macs into running any flavour of OS X, and that is not the least part of my point that G4s are pointless in those beige boxes. It isn't my belief that no-one should do so, though.
My rebuilt PowerTower Pro 225 is giving me such grief at the moment, however, that I am tempted to make it run Jaguar as punishment, when I get it going.

That's your lookout, sir, I run OS X (note: not necessarily the OS X you are thinking of 
) on anything I can because I don't like OS 9. I've even run Tiger on a 8550 WGS with a G3/366 in and it went well enough for me to not run away screaming. Incidentally I bought the last G4 he had listed this morning (a really old XPC7400/400 ZIF) for said same 8550 WGS.
Does anyone know if OS X Server 1.2 supports G4s? I thought it did...
Oh and while I'm at it, NOT all ZIF CPUs are born equal. Some of Motorola OEM Apple G3s apparently don't work on the XLR8 ZIF carrier. I have a G3/400 out of my B&W PowerMac that's sat in a box on a shelf, that I *was* going to put in the 8550 WGS, but, alas it doesn't work in the carrier, and the seller has said to me that he's had issues using Motorola OEM modules on XLR8 carriers (I tested a G3/400 and my seller also tested a G3/400 on his to see if it was a fluke) on many occasions, so stick to IBM G3 modules if you can. I have no clue if the G4/400 I bought will work but at that price I can afford a spare knocking about

At this remove from the seller, anything that we think or write about his enterprise is otiose. 'We' could be another eBay one-man show. Even if he pulls and cleans the ZIFs himself to save on labour costs, he cannot, at his prices, be considered to be a profiteer. Take the careful packaging and flat-rate postage into account, and his margins are vanishingly slim by Western standards.

Yes.
This place is a good start.
OWC has some info for you also.
MacGuru's appears to share the love as well
Now go forth and arm yourself with knowledge before you valiantly kill your machine in the bliss of ignorance.
Ah. I've signed up for email notification when he lists new items. He lists regularly, but these are the first Mac CPUs in a while.
You can also type in stores.ebay.com/IC-China - this only works if you know the exact name of the store. Adding your country code will list the prices in your currency.
Strange how his '040s are more expensive than the G3s and G4s.
They still make Amigas. They use 933mhz G4's now.

I know, I know.
A good friend of mine uses an Amiga 4000 with an '060 in it. It's his main machine and has been forever. He started on Commodore, then got an A500, an A1200 and finally the 4000 he has now.
I've been begging him to get a new Amiga so he can run more modern stuff. Having a G4 would allow him to run the MacOS emulator. Then he can have access to more modern browsers (Voyager sucks butt), more modern text editors and so on. He would also have ethernet. Ethernet would of course allow for DSL or Cable interweb access. He's on 56K right now. He would also have USB. USB and a MacOS emulator will allow him to utilize much more modern hardware and maybe even flash drives and whatnot.
He could do that now. I have one of those Zorro slot 604 CPU cards. He doesn't want to install it because he says the extensions for PPC support in OS 4 slow down the system or something. I think he's on crack, but it's his box.
What really sucks is that they aren't making any boards right now. Heck if I could get my hands on one of those G3 Amiga boards, I might have a new box and OS to tinker with. That could be loads of fun.
My Amiga 4000 060 has ethernet and USB. Give the guy a break
In all honesty it would be a vastly greater saving of money, effort and screwing around to buy him a G4 Mac. They cost next to nothing these days and he wouldn't need anything fancy, just a G4/450 with 10.3.
It's odd you should mention it really I have a friend (actually he's the Chairman of the Amiga UG I'm the secretary of
) who's exactly the same. His main machine is a towered 4000/060 with a Mediator PCI bus board in it and a 36GB SCSI disk. We *gave* him a Mac OS X machine and he still doesn't use it, the trouble is he's getting on a bit and he has problems with fatigue and bad memory so learning OS X is not something he feels he can cope with.He's right about the PPC Support slowing the machine down, but I think he means in OS 3.x
Frankly, unless you want to run OS 4 Classic, having an Amiga PPC card is a waste of time. It accelerates a small number of apps, and some PPC apps are slower than the 060 versions!I haven't used OS 4 Classic on a 4000 yet (a friend of mine has a 4000/PPC and OS 4 Classic but we haven't got the two to gel yet
) but if it's half as fast as it is on a G3 then it'll knock his socks off I've played with OS 4 on a AmigaONE, I had a A1-XE G4/800 as a loner from *another* Amiga Group committee member (the Vice Chairman) and ultimately it left me wanting something more. Here I was using a computer that out-spec'd my iMac G4 and the OS felt like it was made in the stone age. It's fast as hell but ultimately so out of date it's hardly worth it. It has zero benefit over running 3.9 on a REAL Amiga.
A great number of decisions were made incorrectly with the AmigaONE, and OS 4 was chronically understaffed and received very little financial backing. There are projects underway to bring modern software to OS 4 but it's only available sporadically (either with a A1 board, or for Classic Amiga PPC) and has very few developers. Porting something like Firefox could take half a decade at the rate it's going... by which time it's already totally obsolete.
As a viable proposition for anything, Amiga has been dead since about 2004. It still carries on in the hearts and minds of enthusiasts young and old, but we are not enough to shout about or get any viable business model together. It's not helped by the fact Amiga Inc. are squandering and wasteful of the IP, and are financially incompetent, liars and also corrupt and have gone bust at least 2x.
Ahh the World of Amiga - it's so full of joy
Chalk this up as thread number 2 taken over my my rambling about he sorry state of Amiga...
'Registered post' means different things in different countries. For me it means that a card arrives in my letter box telling me that something 'registered' (ie, listed and tracked with a number beginning with 'R', and automatically insured) awaits me at the local PO, to which I then have to haul myself and sign for the article. It may be completely different where you are.

ZIF arrived yesterday. Packed safely and matches the listing precisely.
One little surprise - in the corner it has a trim dial with numbers around it, presumably something to do with speed setting. So it must be a 3rd party upgrade.
/edit/ All hail Google image search. It looks precisely like this (Warning: large image)
And it's actually a 550MHz part - the markings on the sticker are:
PFG4/Z550/220/1M
Z405020191
And the chip die itself indicates a 7410 G4
Going on the hunch that PF=PowerForce by PowerLogix, it seems we have a positive match.

I'd have said so, dialy things for speed are not anything I've seen on XLR8 or Sonnet ZIFs...
He does sell 3rd party upgrade parts, the G3/500 I bought was a Sonnet labelled unit.
To report, the G4/400 didn't work on my XLR8 ZIF carrier. It powers on but I get no chime. Now it *might* be an issue with the RAM in the machine, apparently G4s are fairly unforgiving at best apparently. But alas as it's an 8550 I'm not getting into stripping out the RAM and all that jazz.
I put the G3/500 in instead, which has picked it's skirts up more than somewhat (as you'd expect for doubling the CPU clock speed). Still got nothing to use if for but hey.

ic-china's offerings have included many Sonnet ZIF daughtercards, both G3 and G4 at '500MHz'. The CPUs have generally matched the '500' in their on-chip manufacturer's numbers. I have G4/500s in a Beige DT and MT, the chief advantage there being no necessity for jumper-twiddling on the MLB. The second advantage is that the machines fly in OS 9.2.2. The G4 ZIF card that I bought out of the offering that prompted this thread was listed by ic-china as a 400MHz, which the Motorola marking confirms, but it is on a Sonnet-made card with labels claiming 500MHz as well as the the 1MB cache. I haven't yet installed it into anything, but I shall be interested to see what speeds it settles on in 50MHz and 66MHz bus systems.

I got my G3/450 yesterday too and installed it in my beige G3 and it runs well. I have the bus at 75mhz. Boot times in X dropped 5 seconds, but booting to OS9 gives timebomb errors and hangs, but it'll boot to 9 okay with extensions off.
I think I might OC it to 466, just because. I need a better thermal transfer setup though. It gets kind of hot... My old G3 chip had some kind of thermal transfer "pad" ontop of the processor, but the new one does not... is there somewhere I can buy a new one? I can't get the old one off. Does anyone know what I'm talking about?

Thermal paste is always, both notionally and in practice, better than thermal pads. The function of the paste is to displace the air in the minute crevices, craters and valleys of the machined metal surfaces of CPU and heatsink, and to provide 20+ times better heat conductivity than air can. Even water can do a good job, but heated water doesn't hang about for as long as good-quality thermal paste. Thermal pads, not being metallic throughout, and much thicker than a smear of paste, sacrifice conductivity for plug'n'play convenience.
Take special note of Bunsen's 'tiny smear'. You are just filling invisibly small spaces that are much less deep than a smear is thick. More is decidedly not better than less in this context.
de
de
It's not that I have an issue with applying thermal paste.
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.
Any suggestions?

Any suggestions?
A few—very few up to G4, in my experience, and those are usually third-party daughtercards—came with a stabilizing hollow square of compressible material to fit the perimeter of the CPU. The spring-tensioned heatsink rested on the central 'land' of the processor—between which and the heatsink the heatsink compound was applied—while the heatsink was prevented from wobbling by the hollow square of compressible material. If time and use have caused the heatsink not to perch on the CPU's land in a stable manner, with a little care and ingenuity you could fashion something suitable.

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?

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.

" 10x ratio is not supported on all G3 CPUs,

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.

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.
)] ]'> Well, I haven't figured out the 9.5 setting yet, and the 9.0 is just what's been reported by the funky monkey.
What machine are you running, and is it a Newer ZIF with jumpers, or a PowerForce with dial? Is 10x the only one you've tested, or can you help us confirm any of the other settings?
When I say confirm, I don't mean for stable long-term performance; just long enough to verify the CPU speed corresponds (or doesn't) to the predictions.

yea sure...
hmm testing would mean to rip apart my nicely done setup. My ZIF has DIP switches but the settings correspond to teh newer tech settings. its just inverted.
no jumper means for me to set the switch to the "on" position.
Im running it in my PM 9600 as i said using a daystar ZIF carrier.
i may test the 9x setting if i can find some time.

My 200 watt power supply in the B&W has just now bit the byte, and i personally blame everyone here.
For weeks I have been getting freezes everytime my Optical drive started ramping up to top speed or i attempted to do multiple gigabyte transfers over LAN. I should have known better than to load up all the slots in the mac and not check the wattage on the PS, which it turns out is a paltry 200w. So a new PC-ATX 420w is going in tomorrow, and I'm going for the magic 700Mhz @ 100 bus mark (B on the dial), as it would boot to at least the mouse and rounded corners at that setting. Just something to consider when attempting the higher speeds, those olde PS units can probably power the CPU but as soon as something else drains the current, (like a hard drive) they crash, i suspect that it is the on-chip cache that is the real culprit. I find that heat is not really the issue as there is no increase in voltage as you can do with PC boards when overclocking.
On another note, I noticed that there are only 6 pins coming out of the dial on the G4 ZIF not the 8 or 5 that i would have expected for 16 different settings.
I am curious what y'all use for stress testing for stability, as there are heaps of apps on the WIN-PC side but not much for running the cpu at full tilt on the mac. For quick tests i drop in a cd and dump to mp3 in iTunes, but there is no error checking on that, just full cpu usage.

I find that hard to believe personally, given that anytime I've over-clocked anything it's crashed under some sort of heavy load as a result, and disk access or network access is a prime cuplrit as that puts a lot of traffic across the CPU. If it was true then my B&W running a stock G4/500, a Radeon 9200 and 3 hard drives (2 of which were 10krpm SCSI) would also have struggled, and it doesn't. Faster CPUs have a bearing on it, but also consider that people run 1GHz G4s and G3s in B&W PowerMacs without issues. Although only rated at 200W, the PSUs are very good ones and the 200W output rating is a pretty accurate number, rather than these cheap crappy PC PSUs that say they are 500W and are actually substantially (and in some cases scarily) less under heavy load.
I think you may find the reason it's locking up is the CPU is running too fast, and can't cope with the memory swapping that that sort of ethernet traffic generates, and it's crashing. I suggest you get hold of the Altivec Fractal Generator and run a few repeated runs on it and see if that locks it up. If it does it's time to hang up the over clockers tools and step it down a few notches. It's a typical over-clockers reaction to blame everything else rather than the decidedly risky over-clocking they are messing around with [] ]'>
You'll either suffer lockups for the rest of eternity, or blow the CPU completely (much less likely, but more so the higher you go). Even if you get it stable at a higher speed it'll last a lot less long than it would at it's factory setting, and, given it's probably second hand anyway, that would have me worried about it's life span.
