Holes in memory? Help

[TomKeric]

Hello,

I have a lot of instability with my A2000 and hope someone can point me to what todo.
I think my issue is related to memory

Attaching images from Amiga Test Kit

System etc:
Amiga 2000, rev 6.2,
GVPSeriesCombo2, 12 mb (4mb soldered, 2X4mb memory)scsi controler.
8mb ram a2058. (I think it is jumper set to 4mb)
Indivison ECS v1
I use Micromys 4 for USB mouse
SCSI2SD 5.0a

Thank you so much for help

Hi, why don't you run a memtest?
I think it will show you where the problem is.

i think an amiga 2000 with stock cpu can only see about 10mb ram total,including chipram,try configuring it differently,so you have 8mb of fastram total and dont above it
and see how you go

EDIT: i think you have a 030 card that supports 12mb,remove the 2058 and see if the problem goes away,see if it narrows it down
