I have never seen a more perfect application of thermal paste in my life. Spot on. 👏

[@mwmiddleton]

I'm sure TronicsFix would say it was almost the perfect amount of thermal paste.

[@agizm0]

It's just like my Quicksilver: Dual 1.8ghz (GigaDesigns) 1.5GB RAM ATi 9800Pro SeriTeK SATA card with SSD Pioneer DVD burner (SuperDrive compatible) Replaced every fan with Noctua units

[@PixelPipes]

Love it! It's cool to see new life breathed into old machines, which really, I think is the essence of what we're all trying to do in the retro tech community. And when that 7800GS left the factory, I doubt it could ever imagine what its fate would be 15 years later. Do I personify inanimate objects? Why yes, sometimes! Doesn't everybody?

[@BrightSpark]

From my point of view: As long as the CPU doesn't get too hot and you didn't use a trowel, it'll be an okay amount of thermal paste.

[@BoboZimbabwe]

You have no idea how much I needed this today.

[@MichaelAStanhope]

I treat performance per watt like a golf score around here! That is the funniest thing i've heard when describing the PowerMacs :)

[@UpLateGeek]

That's a pretty impressive gain in performance! It's kind-of shocking to think how much further they could've taken these machines if they were less about trying to make people buy whole new machines, and actually offered upgrades for previous generations. Like, not everyone's going to spend $3-6k every 2 years for a whole new high-end machine, but they might be willing to pay $1k for a processor upgrade.

[@singletona082]

Looking at apple now you wouldn't think that they'd have ANY sort of history of any of their hardware being easy to work on. Looking at apple o fthe past you would think they'd activly advertise how easy it is for users to open the thing up. no mysteries, no scary bits. Meet your computer. It wants you to look inside. This build is genuinely astounding and scratches an itch I have but am too broke to indulge in. This, the mystic, and GS builds have been jawdropping.

[@neeneko]

I think they got locked into a bit of a vicious cycle and culture war problem. When Apple focused on making their systems expandable and user servicable, it was pretty thankless. the tech crowd hated them on principle (after all, artists and other non-techs liked them), and they were not going to ever be able to compete with the flexibility of the IBM clones nor did they have the hard core market of amiga, so eventually they just gave up.

[@TonyisToking]

The easy to work on mantra of the past was one of many that died with Steve Jobs. It was one of the many policies Steve had to fight for as it was very costly to Apple’s bottom line. They know they can make much more if users are forced to buy a new product.

it's not the amount that matters, that it's full coverage on a bare die does. Make sure it actually contacts the whole shiny bit there and that's good enough. The pea sized thing is for CPUs with heatspreaders built onto them.

[@acumenium8157]

It is also largely a myth. Unless the paste is conducive, and 99% of non-liquid metal ones aren't, you can't put TOO MUCH, as it won't harm anything. You can, however, put too little.

[@kiaas]

@@acumenium8157yeah, but if you put "too much" and it squeezes out such that it doesn't give full coverage of a bare die, as just sticking a pea-sized blob on it might do, then it's not enough. Those tubes come with spludgers so you can spread it out and prevent that.

[@NoobixCube]

There is literally no such thing as too much thermal compound. Not enough, and you don't get good coverage on the heat spreader, compromising your interface to the heat sink. "Too much" and you're just smooshing some out the sides where it'll do no good, but it's not like wasting a few grams of silicon grease will appreciably reduce your cooling performance. Not on any scale that matters to a CPU, anyway. Personally I like to spread the paste, myself, so I can see and know I've got good coverage, and my rule is "spread it like Vegemite, not like Nutella", but as long as you get coverage, you're fine. Caveat: using too much _silver_ thermal paste is a bad thing, because that stuff's electrically conductive, and if you smoosh that out into the wrong place, you could short something.

[@MrDeelightful]

That Vegemite line is gold lmao

[@NoobixCube]

@@MrDeelightful Something possibly only Australians will get. Not even the British with their Marmite will quite get the idea, because you can spread Marmite quite thick and still enjoy it.

[@ikwilgeenkanaalzeur]

Love the design of this Mac. Easy to open and acces to everything. We had these on our design school and these G4 Macs were absolute beasts at everything we threw at it.

[@NaoPb]

I love the stuff you do with these macs. It makes me feel like playing with my old (non-mac) hardware again. Maybe try to run Minecraft on a P3 or P4.

[@chadmasta5]

I wish it was this easy to adapt newer x86 cpus to older sockets. Imagine being able to slot a core 2 quad in a 486 board.

[@johncate9541]

Big difference here, though. A G4 was basically a G3 with AltiVec, and a G3 was just a 603ev with better cache management and a beefed-up FPU. All of them would run on the same sockets and core logic, because they were just improved versions of the original. Cyrix actually did do something like this with their 5x86 CPU. They took the 6x86/MII design and removed all of the features that weren't compatible with the 486 bus and core logic, and made it fit in a 486 socket. It was the fastest thing you could run on a 486 socket, in fact, beating AMD's fast 486es and Intel's PODP. If they had kept the design on the 486 socket and crammed MMX on there, made it address memory at 64-bits internally, and added a huge on-die L2 cache...well... But they didn't do that because there wasn't demand for it (they did develop the 5x86 into the MediaGX SOC, but that's a different story). There was demand for making better and better 603 processors, aka the G3 and G4.

[@joefish6091]

DX4-120 DX5-133 all on the 33 MHz 486 bus. The speed of 486 machines is best illustrated by the fact that it took five minutes to make a three minute MP3. The 300 MHz PCs could do it faster than the song length. An emulated 14MHz Amiga A1200 decompresses a 100K lha file in two seconds, my dual E5-2690 32 cores 4GHz PC does 1GB in 10 seconds.

[@mikequinlan9585]

I love the QuickSilver I still have mine, with the original monitor, keyboard, and mouse all packed away I their original boxes. 😊 This computer was such a great user experience I’ve held on to it for all these years.

Love those modded CPU's, not like i have one because I cant afford it XD But the work that dude is doing is awesome with the custom designed interposter etc. But may I ask do you know why he opted to not install the 1-2MB of L3 cache? Im pretty sure these 2Ghz G4's has the 512K L2 cache but even on my inferior Sawtooth I saw a FPS gain of 48% in Quake 3 going from a G4 800Mhz with no L3 cache to a 800Mhz with 2MB L3 cache. Also the OS X experience went from meh to awesome. Is L3 not supported with those processors because and if it is it seems like 2MB of L3 per CPU would offer WAY more performance considering the memory bandwidth dont change with the CPU speed and two processors sharing it should make that problem even bigger. Would love to see dual 2Ghz with Dual 2MB of L3 if possible! Think that would kick ass on a howl new level. EDIT: i realized that the answer to my own question might be there are no L3 cache chips capable of running at the speed required with that core clock (2Ghz) even with the lowest L3 cache divider. Still begs the question, what is faster, L3 cache plus as high as you can go on the G4 or no L3 and even higher core clock.

[@axi0matic]

I think these ones have fast L2 cache and no L3 cache.

@@axi0matic Im pretty sure it has the bigger 512K L2 cache but I recall seeing lower clocked versions of that with 1MB L3 cache also installed.

[@axi0matic]

@ isn’t that the 7455?

@@axi0matic From what I can find the 7447 and 7457 has the 512K L2 cache and supports 4MB L3 cache apparently. Idk what chip is used here but the 7455 seems to be the option if you want 2Ghz so L3 should be supported. Also there is the 7448 with 1Mb of l2 cache, but again idk whats used on this card, maybe thats whats being used? There is no mentioning of L3 cache support on the 7448 so could explain why it was not used. 1Mb of l2 full speed cache is pretty dam cool to say the least! No expert on the subject, could never afford an upgrade like this anyways XD

[@axi0matic]

@ The 7455's were the ones used in the later G4 towers. They had 2MB of L3 but max out at about 1.5GHz. The '57 seems to be the one you're thinking of (the '47 is the version without L3). The 47 was used in later G4 laptops; the towers had moved on to the G5. The '48 is the ultimate, and is probably what is being used here. G4's used smaller process nodes as they went on, so the final versions were both the fastest and most power efficient.

As predicted, when applying thermal compound, make sure you spread it across the entire die. With an IHS it doesn’t matter, with a bare die, you could kill it and the CPU wouldn’t even know it’s baking

What do you think happens to a blob of paste when pressed hard between a die and a large, flat metal surface?

Awesome video! Until now, I had no idea that Apple once made Macs that you could work on without exotic tools like pentalobe screwdrivers and heat guns, acrobatics to avoid damaging ribbon cables and connectors, unique disassembly guides and custom adhesives for reassembling. I guess it still took some hardware hacking to make off-the-shelf parts work with them, but apart from that, those old PowerMac G3s and G4s look fun to work on.

[@audimaster5000]

I totally did the screwdriver, pentalobe and tri-lobe dance today replacing an iPhone battery. Apple has been hit and miss with this type of user customization design. I remember often on G4’s and G5’s stuff even though it seems easy to ‘upgrade’ or replace, there’s always getting the hardware to jive with everything else. Or the drivers/firmware not existing or being incompatible under the operating system or software. It’s a trip seeing this upload.

[@joefish6091]

Be aware twenty year old machines may have been worked to desth, they can be fragile. Don't be too tempted to spend too much on specialized upgrades if the machine is going to be short lived or barely used.

[@axi0matic]

@@joefish6091 Computer speed increased a lot faster in those days - the difference between a 2000 and a 2010 machine is enormous. So it may have had a shorter working life than many machines would these days. CPU upgrades are pretty rare and expensive these days. I wouldn't spend a lot of money on one either, as even upgraded, it would likely still be outgunned by a Raspberry Pi. You're better off just buying one that had high-end specs from the factory, as they're not much more expensive than the lesser models. And at the end of the day, once the nostalgia hit has passed, it's unlikely to be used much anyway.

[@HandFromCoffin]

Man I had a cube I upgraded with a G4 dual 500mhz card and a flashed PC GeForce MX4. I loved that thing.. I still kick myself for getting rid of it. I also had a blue G4 upgraded to a 1.4ghz G4 card I got on ebay. Researching that card it seems it was some high temp G4 that was overclocked from 1.0 to 1.4.. or maybe it was 1.2.. I forget. Wish I had that too. The speed between the dual 500 and the single 1.2 was interesting. You could feel the dual 500 was "smoother" in the GUI and some apps, but the 1.2 over powered it in some apps.

[@fsfs555]

I usually recommend switching the airflow direction of the CPU fan on the back, because normally it blows inward. Since the CPU fan is pulling air from the back of the computer there's a good chance it's taking hot air from the PS and just cycling it back into the case, especially if the tower is in a small enclosure or smushed against a wall. Also the CPU fan in stock orientation blows into the back of the optical drive which often has its own exhaust fan which would be trying to blow out. Kind of makes for bad airflow. These machines are known for PS faults and unfortunately, because of ADC and its unique 24V line, there are no drop-in replacements available; you either have to mod an ATX one and lose ADC in the process (not a big deal typically) or try to source/repair an original PS.

[@expexp562]

[@ukmk3supra]

I was lucky enough to get two dual cpu cards from herd - one with a pair of 7457's, one with a pair of 7455's - only 1.2GHz, but may still have some more MHz inside them if i push them. The reason for sticking with the 7457's and 7455's is the L2 cache size and L3 cache support. I have a Digital Audio 733 that i plan on modding with a QS2002 board & PSU.

[@dosdude1]

You should be able to get 1.5 GHz or so out of a 7457 no problem. The issue is the L3 cache is limited in how fast it can run (and it is based on a ratio set in the card's SPD EEPROM of the CPU clock speed). I was able to locate some 333 MHz rated 1MB L3 cache chips, and installing those along with flashing the SPD EEPROM with a dump from a 1.42 GHz MDD CPU card (which has 2x1MB L3 cache chips per CPU, along with the highest ratio) should allow for even faster overclocks, with the added benefit of having 2MB of L3 cache per CPU.

Was there ever a (commercially available) 7448 based Mac-upgrade? I don't think so, the MPC7448 was actually just a different name for the e600 generation and would have had 1MB L2, which would have been a massive boon for the notoriously FSB-throttled G4s!....

The system bus speed of 133mhz is what really cripples this system, even with a CPU upgrade. That along with the AGP graphics card. It works better with a CPU upgrade but still that bus speed :/ I had one running Debian for a long time. Too bad all these tech companies are making machines that are all soldered down and have no upgrades. I think you might want to try MorphOS or AROS ha.

I have the box for this and the in store demo cd to the demo is weird it runs under 9.2 but it came out in 2003. I also have the imac g4 instore demo cd to.

I also have a rare g4 server thats in a consumer case and its not the xserve.

Let's get a 20" iMac G4 mod!

Minecraft on this runs pretty much the way it did on the first PC i played it on. Granted, that was a much, much older version, so i bet this G4 is actually faster than the Pentium 4 machine i had.

I've got a QS for this same end goal, though my specs will be somewhat different by the end if I get around to it -- dual 1.67GHz 7457s, a 7800 GS, a SeriTek 2SE4, and I'd love to find a way to get 1GB PC133 sticks made for keyboards working in the QS. Maybe a Radeon HD 3850 for Linux.
