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

@GPT
How offent does ppc programs or games usual crash if they are well written?
well written? not often!
All my ppc programs and games usual crash after a couple of minutes if the cpu load is heavy.
doesnt sound like a software problemIt real anoying when I play games like FreeSpace or shogo and 90% of the games the ppc crash before I have finished a level.
it is probably heat, or a crap PSU, what PSU do you have?
I have a A1200T BlizzardPPC 603/210 060/50 80MB and BVision.
is that overclocked? if so, keep it at the normal speed.
it looks like a lot of stuff, make sure you have a good powersupply for it, and plenty of room for air flow, and makesure you keep it cool
-
I havn't overclocked it (jet).
But there is some blue/green stuff that is suppos to be thermal paste but it's hard and I can't move the heat sink nor the fan.
I tryed to scrats it of but it's little space for that kind of operations.
I noticed a thing now that I newer noticed before:
One of the legs is MISSING!!!!!!!!!!!!!!!!!!!!!!!
But it works okay.

If its your 3D games that crash most, maybe your BVision card is overheating. They do get a tad hot!
-
A leg missing on what? You cant see the legs on the 603..... To get at the 603 you have to remove the big black heatsink by taking off the 2 steel clips, mine came off easily. All the white thermal paste had all dried up and gone like a powder so I put some fresh on, replaced the heatsink, put he clips back in and she's been running fine ever since. I also have a fan, no heatsink blowing on my Bvision, nothing in my machine has been overclocked.
-
Hi Ryu,
There's a power amplifier heatsink thats ideal for the Permedia2 chip on the bvision - look for one with tall angled vanes and tack it on with some good heat xfer compound. Seemed to improve my system stability. Pity I have still have the weird
graphics glitch (http://www.amiga.org/forums/showthread.php?t=684) that seemed to affect some BVision cards...
-
The BVision is fine I already have a heat sink and extra power through the floppy power connection.
It´s the glue thermal past that don´t work as good as it used to.
You can acualy see the legs on my 603 ppc processor and one leg is half, the part from the processor to the soldering.
The only thing that keeps the heat sink in place is the glue stuff and there is now clips mecanism of any kind.
My problem is that I don´t know how to remove that glue in order to replays the glue and the heat sink.
If I try to ripp it of the processor will probably follow with it and I will have no working ppc processor anymore (if I don´t solder it back on ;-) :-D ) .
-
Then sir you have a strange BPPC :)

Note: the image is hosted locally here, so might not always be here :-)
-
No I only have a newer BPPC card that has a processor that faster and cooler than the one you have.
-
hmm AFAIK all PPC's come like that from new, yours has been changed at some point then....
-
Couple of problems there:
1. I doubt theres anywhere in Skittyhorpe stocking such stuff
2. Im unable to order online, I dont have a Credit card and my Debit card isnt accepted online :(
Anyhow I have a heatsink for the Bvision, I just chose not to put it on the 3rd Bvision, I did on hthe previous 2 and they died..... this ones been running fine for almost a year now I think.
-
hmm im too used to the automatic replying to comment number thing that ANN does :-)
-
There are indeed two types of bpppc. The sloweer ones like mine have full size ppc and yu can see all the legs round the cpu under the sink. on the faster ones the ppc cpu is hlave the size only takeing up the centre of the cpu area, can even see the soldering pads where the full size cpu could go.
As too heat..well i noticed the fan wasnt working the other day, only been on 2-3 mins and the ppc sink was quite hot so either ppc is burning up or the thermal adhesive is doing its job ;)
as too the crashes...well they happen totaly randomaly for me, i suspect bad psu so am going to try a replacement.
