Yanno I’ve seen those go for close to $100 USD here in the states, so that auction BIN isn’t half bad. I thought twice about buying it myself lol.
Congrats on your purchase. That is one card I’ve always wanted.
I’m curious how it will fit in the QS case.
That thing is humongous.
What could be causing this? Some kind of logic board/CPU issue?
If the videos in question are playable in OS 9, you might try that and see how things go. I'm thinking the 4600 may take more of the load off in OS 9 than it does in Tiger, but in any event OS 9 is far lighter on resources than OS X. If nothing goes wrong doing the same tests in OS 9, your CPU might be the culprit.
I can test this out in OS 9. Which media player would you recommend for OS 9?
I'm not much of an OS 9 guy, but QuickTime used to meet all my needs. QuickTime 6.0.3 is the latest version you can run pre-OS X. Some people over at Mac OS 9 Lives recommend 3ivx, but I've never used it. Then there's @alex_free's efforts of late, here and here, but I haven't tried those yet either.
Surely some of that will be of some use? Seems the Classic Mac life is just passing me by. ?
Some quick & easy things I’d test are:
2. Ram - swap each stick & test for artifacts
6. visual check of agp port for visible debris.
1. Video cable swap
3. PSU - test with multimeter for good 12, 5, 3.3v power
4. Swap with another QS cpu
daughtercard?
5. Visual check for bulging caps.
@TheShortTimer I would try testing the "faulty" video cable that the QS was using with another machine. Maybe it will present problems there?
That might give you a little better idea of the situation.
Initially I was hesitant because the VGA cable and LED monitor set up are faultless with the Sawtooth.
As I understand it, you're using a VGA cable over a DVI to VGA adapter from the card's DVI output? What about trying the card's straight VGA output?
How hot is the card's heatsink, and how is its fan behaving? Have you tried cleaning out the DVI pins / holes?
I would definitely keep testing its VGA signals like you are, you might be onto something there about its signals failing if none of the above proves useful.
Good luck trying to get your money back, unless the seller offers returns.That's right, for several weeks I'd been running the card to my HDTV over HDMI with DVI to HDMI. In light of the problems, I've now instead tried the 4600 with a different monitor that has a VGA input by using a DVI to VGA adapter connected to a VGA cable. The card doesn't have a VGA port, there are two options - DVI or Apple Display Connector
The heat sink and fan appear to be combined.
It's difficult to see what's going on because of the way cards are positioned in the G4 cases but I could try and film it. Would should I be paying attention to in terms of the fan operation and the heat sink? The DVI ports sockets seem to be clear.
It does appear to lead towards that conclusion. When I run the card via DVI to HDMI, the problem now manifests itself immediately when a video is played straight after the desktop has loaded, which makes me suspect that the failure has begun. Should I contact the seller and ask for a refund or should further troubleshooting be explored first?

From the picture above, I don't see any bulged or leaking capacitors, but take a real close look at them.
Otherwise, if you can't get a return, try a ADC to DVI adapter. the card has two SI TMDs's for the digital signal, if you are lucky, it maybe the one on the top that is failing, and the one that drives the ADC port maybe ok.
I would pursue a refund. I think its fair within the timeframe of buying and int'l shipping and testing the card etc. I mean you've only had it for 17 days. You've experienced problems that frankly, I don't think should be there. IIRC the 4600 was advertised as a working used card and this is not IMO a "working" card. You've seen what a working card looks & operates like with the Hrutkay mod video. This card is doing wacky stuff. I'd not hang onto it if it can be avoided. Shoot the seller an email immediately stating the issues, and request a refund.
If for whatever reason ebay loses their marbles and sides with the seller, the first thing Id do is pull the heatsink, clean the gpu and repaste it, but I think you'll be ok.
Good luck.
eBay has a money back guarantee. If the seller is completely uncooperative, eBay will usually just refund you the money themselves and apologize for the inconvenience. My guess is that the seller's account then receives some kind of consequence as a result.
If you aren't actually hearing anything suspicious, the fan is probably operating normally.
Just touch the metal. If the surface is very hot, I would try repasting it and then see if the problems go away.
I don't think they would cause any issue with what you're experiencing, but check the RAM chips also. Case in point, putting heatsinks on an R300's chips is pretty much a requirement if you want the card to live a very long life. Tons of cooked boards out there due to insufficient cooling.
I would use a toothbrush with rubbing alcohol to brush out all the pinholes of any undetectable dust or slight corrosion. It's not that likely, but there does exist a chance it could be connection related. Some pin not sending the signals it needs to when called for, maybe.
