That's just great - another way to get dual-link DVI on Jaguar
Can you run kextstat | grep Radeon in Terminal? That will tell which kext is loaded.

EDIT: Is that good/bad/surprising? As I said, I have done absolutely nothing to mod/patch/alter the Jaguar install, other than install from the iMac 10.2.7 DVD and then update to 10.2.8. And yes I can confirm that Escape from Monkey Island (the instigator behind installing Jaguar) runs well in Classic

Now, next step - suggested by @Amethyst1 - is to replace the jumbo jet fans on this MDD for some quieter ones.
I've come across some other threads of people that have done this, but they are quite old so the fans they recommend are either discontinued or unavailable in Europe.
Is there anyone that has done this and would have some tips? @LightBulbFun I know you have a MDD and are in Europe, do you have any pointers?
Thanks!

Interestingly, I just had this issue under Jaguar. Was just browsing through system preferences when the thing froze. Doesn't seem to happen very often though.
I'm in the UK, where are you based? What are the specs of your MDD?
@David Hassholehoff @r6mile It is most likely the RAM. I had the same problem in mine with four sticks of 512mb DDR-2700 reoccurring every week or so until I swapped them out for two 1gb DDR-2700 sticks several months ago. Haven't seen one freeze since.
You can verify this by checking the syslog in Console or Crash Reporter after a crash or freeze for "EXEC_BAD_ACCESS", which, to my current knowledge, discreetly points to incompatible memory.

I'll check it again when I'm done preparing room for all my old machines.
Anyone know what RAM is good in the MDD? Anything one can get easily?

I have 4*512MB PC-2700, two Kingston and two Crucial sticks. But you can use PC3200 RAM too (it will downclock), and any other combination of sizes as long a it doesn't exceed 2GB. Ie 1GB+1GB, 1GB+512+512, 1GB+512+256+256, etc...
@r6mile To be fair, using more modules increases the chances of happening upon an incompatible stick.
It is for both this reason and to put less stress on the memory controller, I would recommend two 1gb sticks in slot 1 and 3 (to better dissipate heat) instead. They should be unregistered, non-ecc modules, clocked at 333, with a timing of CL 2.5, and ensured to make a totally clean connection before installation.
I think these are about identical to what I used. Micron is excellent.

The ram on mine tends to keep it from booting if it wiggles out of place when I close it up, and I only have 1.75gb, and none of it matches, so less possible moving parts and a full upgrade to 2gb would be an excellent solution.@r6mile To be fair, using more modules increases the chances of happening upon an incompatible stick.

The only thing it leaves me wondering is why a computer that accepts 1gb ram sticks and has four slots would stop at 2gb, but I suspect people have been wondering that for nearly 20 years now.
@repairedCheese My best guess is that, true to form, Apple didn't want preexisting G4 machines in competition with their secret G5 project, even though the 7450+ architecture could handle it (as @JoyBed has recently discovered, if memory serves).
Planned obsolescence is in their DNA.

I do have to wonder how a PMG4 Dual 1.42ghz with 4ish gb of ram would compete against a PMG5 SP 1.6 ghz that only maxed out at 4gb of ram anyway. They really were doing that kind of thing with the G5 line, so it does make sense they'd started earlier.
But for that matter, a PMG4 Dual 1.42ghz vs a PMG5 SP 1.6ghz is a battle I'd like to see, even if it's 2gb of ram vs 4gb. The low end of the G5 line doesn't exactly impress on paper, you know?
@repairedCheese I have been told by different owners of both that the 1.6 G5 is generally regarded as slow. Conversely, the dual 1.42 G4 is typically felt to be fast.
Add in SMP, 1mb L3 per CPU, a potentially better GPU and HDD, and of course the G4 is going to win. Indeed, the G5 is a superior architecture, but it's not that superior when put head to head on equal terms.

It looks like you were right. I got the EXEC_BAD_ACCESS message in the console; pretty sure I've narrowed it down to one of my two Kingston 512MB sticks is bad. I've ordered two 512MB Crucial/Micron sticks to match my other pair of Crucial sticks, for £2 on eBay.
I've also replaced the big original system fan with a Scythe Slip Stream, £13 on Amazon. Also repasted the CPUs as I'm pretty sure the original paste dried about a decade ago! This thing is definitely a lot quieter now, though still fairly noticeable (at least I can no longer hear it from downstairs!). I know the biggest culprits are the PSU fans but I'm not sure I can quite face tackling those (and the splicing etc that I think it requires) just yet.
What dimensions are the fans? Do you guys think it's possible to replace the CPU and PSU fans with something modern and quiet?
The big system/CPU fan yes as I've just done it. There are quite a few threads about how to do it, and the Scythe Slip Stream 1900rpm came up a few times.
It has the same CFM as the original fan but is thinner and quieter. The replacement is very easy and takes just a few minutes - there is an ifixit guide.
The PSU fans are supposedly the biggest noise makers, and can be replaced too, but it seemed like a lot more work, with more potential to damage things, so I didn't want to risk it.
You can also replace the case fan, and I'm sure this is very easy, but it didn't seem like this makes a lot of noise.
Are you still looking for a CPU upgrade? There is a seller in the UK with a dual 1.25 board for £13.70 shipped. https://www.ebay.co.uk/itm/Powermac...301607?hash=item2aeea33c27:g:CYsAAOSwGOVfLEsg
I know it's not a dual 1.42 (I've never seen one of those). But if you are still interested I'd be happy to help with shipping to where you are.
So what do you think the shipping would be to the United States? And, do you think the stock single processor 1.25 ghz cooler could handle its dual processor sibling? Because that 1st one is a lot less important if the 2nd one is a no.
Though, it might be worth holding onto...
I think it does support them. The 9500/180DP and the 9600/200DP can run up to 9.1, and the Power Macintosh G4 450DP/500DP were both delivered with OS 9 but no OS X.
It doesn't have much in the way of support, but dual processors are very useful useful in OS 10.4 or 10.5. Or linux, for that matter.
