I figured I should create a thread for people to post and discuss various CPU shots that they have:) obviously this will be PPC focused but other chips are welcome too :) (especially if they are of some usual or rare kind)

I also plan to use this thread to discuss and go into detail on on what I post and others are welcome to go into detail on what they are posting as well :)

lets start with the 1 603ev and 2 MPC740 chips pictured here (the un marked chip top left im saving for later :) ), which ill use to clear up what the "MPC MC XPC XC PPC" markings on Motorla/Freescale/NXP chips means,

if a chip starts with "MPC" or "MC" that means its fully qualified for all uses and conditions as specified in the main datasheet for that chip if a chip is marked "XPC" or "XC" that means its only partly qualified, a lot of Chips apple used are XPC chips due to the fact they only needed to be qualified for Apples own requirements/uses rather then say fully embedded industrial use (the XPC7410RX533PE in a DA is only qualified up to 65c where as a MPC7410RX500LE is fully qualified all the way up to operation at 105c for example) a good number (but sadly not all) of these Apple XPC chips have their own datasheets on the NXP website for us to see how they differ to the main MPC version of that chip :) and finally a chip marked "PPC" is a Pre production or pilot production chip which has not been qualified in any way. (note this is only applicable to Motorola/Freescale/NXP produced chips, IBM Atmel and e2v produced PowerPC CPUs use diffrent designations usually starting in PPC which does in this case just stand for PowerPC AFAIK)

PS you may notice the PPC603 and MPC740s are marked with AIM007 and AIM011 this stands for Apple IBM Motorola (alliance) 7th and 11th design respectively :)

so yeah any pictures of PowerPC and other CPUs you got feel free to post them here :D

I’ve got some I could share...

7806bf9e04ec04fb6b41c4743b9680dd.jpg

First off is my MBP9,1’s i7-3820QM and 650M GT after I cleaned off the old thermal paste to redo it to stop the throttling that was occurring.

Next is the PPC750 (G3) found in my PowerBook G3 Kanga

This is a shot of the 2GHz C2D P7350 from a Early 2009 MacBook’s Logic board that I swapped into a Early 2008 Black MacBook. You can also see the GeForce 9400M as well

Here’s a 1GHz G4 7450 from my 1GHz Titanium PowerBook G4

81688e43522b58aafded8190c912ce96.jpg

As well as the ATI Radeon Mobility 9000 that’s in the GigaTiBook as well

I’ll keep digging through my photos to see what other chip pics I can find, as I know I’ve taken way more than the above selection...

thank you guy so far for your contributions (of actual computer chips...) :)

im glad @bunnspecial posted the picture of that G3 as it ties in with the unmarked 750 :) and the 300Mhz 750A @weckart posted in another thread, for you see the CPU Bunnspecial posted is a 750P not a 750A the 750P was a die shrunk 750A with a reduced core voltage and could hit higher clocks. now when weckart got a 300Mhz G3 beige I was very interested in seeing what CPU it had because officially the 750A only hit a max clock speed of 266Mhz however I was pretty sure the 750P was introduced with the G3 BW so quite interestingly but sort of expectedly weckarts machine had a 300Mhz rated 750A, fast forward to a few days ago bunnspecial got a 300Mhz G3 beige Out-rigger, and i was quite surprised to see that his CPU was a 750P! in-fact its the earliest production 750P iv seen and was made only 2 weeks after this very much a prototype un-marked 750P I have, it even uses the same photolithography mask revision as my Prototype chip (thats what the 81J99D signifies) (bunns chip was made 40th week 1998 and my prototype chip was made 38th week 1998) im curious at to what the 292Mhz and 300Mhz WS/PDQs used :)

this kids is your iMac G4 on drugs! :eek:

iMac-on-drugs.jpg


I recently got ahold of 2 first gen iMac G4s one of them had no RAM but worked fine once RAM was installed :) , the second iMac G4 however did not work, (powered on but no life otherwise) it was also missing its bottom pan and 2 of the 4 chassis screws where missing, and well once I got the heatsink off the CPU I figured out why it did not work...

it is a sad case of what happens when you forget or neglect to put fresh thermal paste on the heatsink contact point between the iMac G4s main dome/chassis and the logic-board as you can see the CPU overheated and cooked its self to the point of melting the plastic gasket and burning the thermal paste. (and im pretty sure the die meant to be purple...) its safe to say this chip is deep fried :D

its worth noting that this is a 7451 rather then a 7450 (they are pretty much feature identical however)

im hoping this iMac G4 will work with a new CPU fitted :)

A while back, we had someone claiming that the 17" DLSD(A1139) came from the factory with a 7448 processor. He was so convinced that he got the all-too-gullible everymac to change their specs, and to this day they carry an incorrect note that computers "might" have come with them.

In any case, that posted put up a photo that didn't really pass the "smell test" to me to support their case. I still have the photo, which I will avoid posting since it's not mine and wouldn't contribute to the thread, but it was pretty obviously a 7447B and they had "edited" the die markings and squeezed the "B" over next to the "744" to make it look like it said 7448. Anyone who has handled both would know this wasn't the case.

In arguing that point, I tore down my A1139-a computer that @Gamer9430 now has-to make my point. Here's an A1178 LoBo showing a 7447B

And a real 7448.

The 7448 is on a NewerTech 2ghz upgrade card. It's part of a Digital Audio G4 I bought from a member here, and the owner had gone all-out on upgrading the system. In addition to the 2ghz 7448, he'd also fitted a FireGL X3 flashed to an X800XT-a "hot" card around here at one time when a bunch of them showed up on Ebay, and interestingly enough this is the only one I've encountered which will even work in a Digital Audio or Quicksilver G4. The computer also has a Sonnet SATA card with a 500gb WD Blue connected to it, a Sonnet USB 2.0/FW card, and a PCI Radeon 7000(the last was a nice surprise).

I really should use the computer more than I have...

I also miss my A1139 after selling it, and need to look for another. That's especially true now that @dosdude1 and @LightBulbFun are having some success putting 7448s in certain computers.

Don’t worry, Bunn, I’ll take good care of the 17in DLSD. It’s in good hands, along with many other machines you previously owned LOL.

What is the difference in the 7447A and 7447B ? I think mine may be B since it came out in the last month off 2006.
