PPC and crashes

[GPT]

How offent does ppc programs or games usual crash if they are well written?

All my ppc programs and games usual crash after a couple of minutes if the cpu load is heavy.

It real anoying when I play games like FreeSpace or shogo and 90% of the games the ppc crash before I have finished a level.


Does the ppc real crash that offent or is there something wrong with my hard/soft- ware?


I have a A1200T BlizzardPPC 603/210 060/50 80MB and BVision.

Maybe it's overheating...

That does sound like an over-heat problem, you may want to try putting a bigger heat sink on the PPC or one with a fan

I've got the same basic problem here, but not quite as severe. I can usually get all the way through Freespace, but on the rare occasion it'll lock up. Another one that locks up a lot is the Subspace plugin for AmigaAmp. Usually I can run any SINGLE ppc task for any length of time. It's when I run multiple ppc tasks that it craps out.

The only thing I wonder about overheating is, why, when I reboot and go right back to the program that caused it to overheat, does it then run okay for an hour or so before the next crash. If it's overheating, wouldn't it take longer than the time it takes to reboot (about 7 seconds) to cool down?

yes its an overheating problem i had this prob two years a so so put bigger fan and heat sink on cpu and also a tower fan aimed at the card never had the problem since i never turn comp off runs 24/7 also check original fan as mine died very early on  :-D  :-)  :-o

I already have a fan and a little heatsink and it's not that hot.

You can toughts it witout burning but I can feel that it's warm through the tower case.

If it is overheating how come the rest 10% of game play work sometimes for houres?

I have one idea, that it could be the 16MB module, it's not original ram but I have removed it before and noticed noting except less memory (Would  be strange iif else :-D )

[GPT]

If it is heatsink as you say how big heatsink do I need?

I havn't overclocked it (yet) so it's not that hot.

Have you tried a different one?

@Roj

Memory is another one to check ( run a memory test prog ) and also make sure that there is sufficient space between the PPC card and the side of the tower. I thought nothing of this until I tried it and when I put spacers on the mobo to offset it more from the RHS of the tower case to my problems ceased although that could have just been air circulation.

PS: Isn't 16Mb a bit low for Freespace?

[GPT]

Are you suppos to be able to move the BPPC 2-3 cm from one side to the other?

[GPT]

16MB+64MB=80MB

Simple math

Sounds like a memory problem to me -

What speed is your RAM rated for, and what are you using it at?

Even if it's rated 60ns, you might try it at 70ns if you aren't
already and see if the crashes stop.

You may also need to change your precharge settings to the slower
option (I forget which that is - check your PPC documenation).

I have a similiar problem though, but only with certain games
like Napalm and QuakeWOS - they always crash within a few minutes.
Lowering the memory speeds didn't work for me sadly.

I had a similar problem here. The heatsink didnt get too warm but it was an overheating problem. All I had to do was remove the heatsink and replace the thermal paste so it conduct the heat to the heatsink more efficiently, been brilliant ever since. Mines a 603 clocked at 160, with the standard heatsink and fan.

I recently replaced my 4 16 meg simms with 4 32 meg simms, and ever since my system has been a little more stable. Still not completely, but better than before.

I'll probably try reseating the heat sync with a little better heat sync compound, and while I've got it apart, I'll also try to find a better fan for it and see if that helps anything.
