Yeah, it's subtle, but once you learn to recognize it, it's easy to spot. As Kenny said, the dull solder joints are a telltale sign, and you might see legs on surrounding components turning green as well. The leaked electrolyte on the boards tends to attract more dirt/dust to those areas as well.

The ones in these machines don't tend to fail that way, they leak electrolyte out the rubber seals on the bottom and it seeps all over the board.

This could also be nice for upgrading G3 upgrade cards for older Power Macs to become G4 upgrade cards. Then again, if you're going the interposer route, why not aim higher than a 7410?

I got impatient and posted another thread to try troubleshooting the boot issue.

Following this post, I decided to start a separate thread about this specific phenomenon to try to understand what's going on. Here's what's happening: The machine boots to a flashing question mark, then quickly switches to a happy Mac, then back to a flashing question mark, where it sits...

Okay, the first time I didn't give it a fair shot; the partition size on the SATA drive was too large. I made a smaller partition and copied my 8.6 system folder to it and verified that the 5400 will boot from that with a SIL3112 card. Then switched to the VT6421A card and it boots to a brief...

The card works fine in the 5400 running 8.6, and it sleeps/wakes reliably, but the machine doesn't seem to want to boot from a drive connected to the card, which is a bummer.

Yeah, fink is right, that row of chips is the root cause of most video problems. I have also found that no vsync can be a PAL problem.

Great! Glad to hear you're going to try it for yourself. I would love to see some benchmarks. I did a back-to-back QuickBench with a SIL3112 and the VT6421A just as a quick sanity check. Performance looked about the same, but I was only using a 500GB Hitachi HDD. I don't have any spare SATA...

It provides the 2.5V core voltage for the controller chip. The cheaper cards just use a big diode in series with the 3.3V regulator. 3.3V - 0.7V = 2.6V; close enough, eh! Some card designs use a 2.5V fixed LDO instead of the adjustable regulator.

Looks like 470 ohms and 10k ohms to me.

@croissantking, that's a seriously hotrodded Beige. Thanks for the info. Are your PCI cards running at 35MHz then? I've never heard of a Switch Power VRM. I just know Royal is the one to avoid. I'm planning on building my own DIY G4 ZIF eventually and it's nice to know that a 7400 clocked that...

There's some wild stuff going on in those MacRumors threads, @joevt. Because this is my kind of fun, I bought a cheap PCI Geforce4 MX just to play with.

Roger that. At the risk of going off-topic, I'd just like to acknowledge how awesome this is. First of all, are you running at 66.6MHz * 8.5 = 567MHz? I didn't think the 7400 supported an 8.5x multiplier. Are you using a factory (Raytheon, Fairchild?) VRM? How are you cooling it?

Interesting insights, thanks joevt! Thanks. You may have noticed that a few of the Kuroutoshikou SATA cards have gone missing as well.

I don't know either, I've only seen the ROMs out there. I do know that the same Radeon 7000 ROM works on both PCI and AGP cards, so it's within reason that the same might be true for Nvidia. This page claims that a B&W G3 or newer is required. I'm not sure why. So this idea is far from a...

I wonder if it would be worth trying to flash something like a Geforce2 MX or Geforce4 MX PCI card to get away from the ATI drivers. They're not fast cards, but not slower than a 7000, and perhaps even less loved, so either should be cheap if you can find one.

This card was listed on JDirectItems and Mercari for a while, but I couldn't justify the price: ...until I found some other stuff I wanted and ended up talking myself into a FromJapan order, so here we are. This is the System TALKS SUGOI SATA-IF150CM. Tested in my Quicksilver, works fine as...

Lots of good stuff there! I dare you to push any of the buttons on the front of the 5x00 😬

Yeah, that's ye olde SDRAM. I'd like to find a Radeon 9100 PCI someday, but I'd settle for a 7500.
