A1200 & AcA1232: "program failed" after 10 minutes...

[Arnie]

If you can't then I've just remembered a program in the System drawer. NoFastMem.

All right, I'll try!

[turrican9]

So did you try using an extra grounding wire, maxint?

[jbenam]

Start with the bare minimum - just the CF card and see what happens You need to first understand _what_ is giving problems, then you can think of how to fix that! Obviously you won't be able to run memory hungry programs without the ACA1232, but you said that the problem happen with almost everything, so who knows what will happen if you run something lighter?

[turrican9]

I am thinking since it runs fine with other accelerator, either the ACA 1232 is faulty, he has not done the full timing fix (or incorrectly) or it could be a case of the need for better grouding. He could always try and lift the Amiga and put a fan underneath to see if that does anything. Normally the ACA 1232 should not need a fan to run stable. But of course he could try and disable all the fastmem to see if that helps. But just trying a simple grouding wire is really no hassle. Just to rule that out.

Here I am: back from work, if my 2 little babies allows me to cure my Amiga , il try to disable fastmem but first I want to make a ground wire.

I made a grounding wire as suggested by Turrican, the Amiga ran speedy for 13 minutes and...Boom again!



NoFastMem resets my Amiga

Now try and lift the Amiga with something and put a fan blowing over the ACA 1232

I can confirm that...we have an overheating problem!!!
Turrican

I pointed a phon on the cpu and the Amiga runs very fast and stable!! I can open multiple programs like Aweb and IBrowse without any problem!

Thank you so much, my friends!

Do you think that i can solve that problem with a heatsink or I must adapt a fan?

Thanks again.

in fact to demonstrate the overheat problem, I turned off my phon and my Amiga started to show "program failed"...

You're quite welcome. That depends if it's the CPU that overheats or the memory. If it's the CPU it should help with a heatsink on that. If it's the memory you will need heatsinks for them. You will just have to test it with putting a heatsink on the CPU first I think. Then take it from there.

I thought the ACA accelerators shouldn't have heating problems normally.

[turrican9]

maxint, would your ACA 1232 happen to be overclocked in any way?

it is listed as: clocked at 20 MHz, 25 MHz or 33 MHz

If it's running at 33MHz, maybe try and clock it down to 25?

My ACA is clocked ad 33MHZ, I never made an overclock. How can I underclock it?
I've seen some setting written on the board, but I don't know how to make the cpu slower, I saw some advice to make a jumper with a resistor between 2 points.

In the meanwhile I can test some heatsinks on the Cpu and the ram.

I think so.

Should say on the back of the card:

awesome, you are very friendly and informative.

Te R1, R2... points are on the back of the board?

All right!
I'll test some heatsinks if my baby goes to sleep...

Be sure to give us updates on the progress
