A1000 - How to reduce available memory ?

[Prot88]

Hi

I have troubles with a Amiga 1000 Golem ram expansion.

Each time I reach 800 Kb of 2 Mb available I have a guru.
I tried to change memory chips but no change.

So, I need to tell my workbench 1.3 not to use bad memory.

I have tried with nofastmem + addmem (start memory) (end memory) but it doesn't work (memory already mounted).

I tried to disable memory with the switch and addmem : no ram expansion found.

Another idea ?

I have grounded all my expansion devices. I will try memeat.

Before that, I must solve a Hard drive issue (see http://www.amiga.org/forums/showthread.php?t=62029) I have unplugged the memory expansion to be sure it is not the problem.

If I succed format the drive I will plug the memory.

Thanks !
