PPC very unstable

[awe4k]

Hi,

I am having problems with my CSPPC. PPC software is quite unstable, leading to WarpOS crashes every now and then. I have not been able to run a single PPC game, and other PPC software has a tendency to crash. Sometimes I cannot even start AWeb-II (it came with OS3.9).

The setup is:

A4000D
X-Surf (original modem) connected to ADSL
Highway USB card
DCE internal scando+flickerfixer
CSPPC 060/50 + 604e/233
SCSI HD connected to CyberStorm
16Mb on mobo + 64Mb on CSPPC
NOTE: It runs with the case open

OS3.9 (kick 45.57 WB 45.3)
Poseidon V2.?

I get occasional requesters "Please insert volume DFO: in any drive" during bootup, although the jumpers on the mobo are ok.

The WarpOS crashes happen usually "during load operation" and at "memory accesses".

Any clue? Do you need more info to help me?

Hello. Yes, all of this is in the original dektop case with the original PSU. I see you suggest a lack of PSU power as one possible cause... could be. What is the cure then? Adapt an AT PSU maybe?

By the way, you mention "PSU fault IMHO. ("Please insert volume DFO: in any drive")". What is "IMHO"? Sorry, if is this an idiot question, but I am idiot. LOL.

CSPPC is from DCE. How can I know which WarpOS version do I have?

Regarding the memory on the mobo, I used to run the computer without it, and I had the same problem

Hello Patrick,

Thanks for your reply. Everything you mention makes a lot of sense.

I'll try and upgrade the cooling on the processors. Also, I will modify the cover of the case in order to increase the cooling with the cover closed, and I'll post pics. I will induct air into the case by means of fans on both sides of the cover, and possibly from the rear too, on top of the "expansion" hole.

I do not know wether the connector of the CPU board is clean or not, but I know that the CS sits properly in its place and is fully inserted. I'd rather avoid the hassle of removing it to check the cleanliness of the contacts. The more I know the A4000's case, the more I like the A2000's case. OH!

In reply to the other post, the memory I have is 60ns, but I'll try another set of SIMMS whenever I have a chance.

Thanks all! I'll re-post in case there were news.

Hello again,

While it is clear that cooling is an issue, it seems that the problems in my case do not come from this point. I just started the Amiga (thus it is cold), tried to run Heretic II, and this is what I got:

So, my problem comes from somewhere else
