Hello.

Does the 750FX PowerPC G3 have any issues with OS4? I remember there was an issue with IBrowse running on G3 CPUs a while back. How was this resovled?

This A1 freezing I have is really starting to annoy me. It can't be reproduced at any time yet will occur when I least expect it. It froze when YAM was loading email headers. It even froze when IBrowse was sitting there doing nothing.

Since Linux runs perfectly each and every time I am thinking that maybe there is some rogue exception that OS4 hasn't been programmed to handle and so just freezes. In my obsevation and programing experience the only reason for a complete freeze to occur is when there is a crash inside an interrupt. An acccidental loop of non-ending code in an interrupt will produce the same result. Even when emulated.

I have nothing else that I can think of to blame. I really prefer the memory errors I used to get eariler before I broke my machine. As funny as that sounds, because it never caused my machine to just freeze up. Now after replacing my CPU and memory suddenly my machine is unstable.

Because of this I have run out of reasons why I don't use a PC. Right now a PC is looking a lot easier. Buy it. Surf the web. No freezes.

@Hypex

I've been using my AmigaOne G3/800 daily for a few years now without any kind of problems (with Dnetc running in background every time).

If you haven't got any trouble with Linux, check your OS 4 installation.

@Hypex

So...anything on serial? Is it related to MUI programs, or programs using network or programs in general?

Sorry, never had any problems running IBrowse on my PPC 750FX. Have you checked your HDD, Memory and Voltage?

Where do you got the new CPU Module?

You have yours hd set to PIO or DMA mode ?.. try them in PIO mode and see if this help..
If not, try to put a better fan and heatsink on your cpu ( the one provided with the cpu is poor ) and then try the vcore settings..

I also get random freezes on my A1XE G3/800, and can find no rhyme nor reason for them.

I have had a problem with my hard drive, not booting, and currently I have the side off my A1. I have a new dvd-writer to fit, and a radeon9250 to fit ready for 4.1, so I'll check my core voltage at the same time.

I also seem to get more freezes when connected to the web, either IBrowse, or OWB, so it may be ethernet connected, but this is realy just an impression I have rather than hard facts.

I would realy be interested if you find a soloution.

I would make sure the CPU isn't overheated and that it has the correct Vcore.

If you replaced the CPU module and got a different CPU you most likely need to change the Vcore.

If I'm not mistaken, a too high Vcore will cause overheating and freezes while a too low Vcore will make it stop randomly during boot and if it boots it will behave wierd but not necessarily freeze.

Remember that the Vcore setting on the mother board may not be entirely accurate if you don't have a perfect PSU.

You may also try reseating any PCI/AGP cards.
Remove SetA1.

750FX does not have any known problems. 750GX had som problems that showed itself
especially with IBrowse. But this cache initialization bug was fixed ages ago.

My OS4 setup was the same as I left it before I broke my G4. I use the same setup with a G3 and suddenly it is random unstableness. So:

EDIT: No wait, I replaced my floppy cable with a modern coiled one. Can a floppy drive not in use cause a system freeze?

And I'd had to log into IBrowse again after rebooting?! Oh yes it just did it again after my last message. I checked my PCI slots and tried to photo my DIPs but it came out just too blurry.

@Mr_Capehill

Although the shell froze on me during some heavy compiling a little while back, it does only seem to affect MUI programs using the network. I tried to get serial output from my "SetA1 PCI" instant freeze but nothing was there. I wish I had a mini computer I could leave connected to serial just incase I can catch it. I updated a MUI class recently and now in YAM some title text is all black and the cursor is missing in string gadgets.

Yes. I had to replace my main HDD as it had read errors, but it never caused a freeze before. I recently checked my volages and whenever I run a memtest (from a boot shell) it comes up fine. I even copied files to RAM until it ran out to see if a bug would occur.

An OS4 developer, Tony Wyatt, sold me his G3.

Ouch! DMA please, on my Sii0680.

The previous owner had no problems with the fan and I copied his vcore settings as he told me. Plus I have a bad history with G4, it broke because I touched the fan. I don't want to change any factory settings again.

Thankyou! At least I don't feel so alone. Oh, Rhyme And Reason, that's one of my favorite songs by Brothers and Systems.

I've checked and doubled checked, and when I posted my settings on AW.net no one spoke up about any problem with them.

The same here!

So do I! Any of us!

I'd really like it if, like the old RAD disk, if you could specify the debug buffer not to be erased on reboot. That would really help.

@Deniil715

Then it is most likely by what you say I would have overset the VCore. But as reported in an eariler thread, I posted my VCore settings, no one said they was wrong.

But I have suspected if the PSU is at fault. The last one I had just died suddenly with no warning. Then someone gave me the exact type I had been using and still am now!

But, if the PSU was at fault, why didn't it show up with a G4 that uses more power and runs hotter?

It looks like I have something of a phenomenon here. I just don't enjoy it!

Oh BTW I don't use SetA1 permanently. I just use it to cause an intant freeze. Which BTW no one has gave me any feedback on. SetA1 will freeze my A1 while looking at PCI, but it's fine on everyone else's machine while looking at PCI shall I assume?

Yes that was it. Damn I thought I had it.

@Hypex

Maybe nothing to do with your problem but....
On my SE i had system freeze,when surfing the net,watching movies with mplayer. The system seemed to go to sleep for some time and then suddenly it started again like nothing had happened. Only change i did was to set my hds to udma 4. Was set to best pio mode. And now i don't get any more timeouts.

I have just checked and my vcore is set to 1.44v (off.on.off.off).

What does the vcore actually do?
What if about reducing it to 1.39v (on.off.off.off)?

Would this slow my system down in anyway?

@Antique

Damn, I had the same problem and could never figure it out. Of course, now I have the problem that it doesn't even start U-Boot...

And I don't have a suitable JTAG programmer for the 750CXe. neither do the Friedens...

I do however have an old PPCBoot flash chip, maybe I could try that...
