Problem with memory expansion?

[ChaosLord]

Hi,

I bought an Amiga 500 a couple of weeks ago which included a memory expansion in the expansion slot underneath. While running the computer, I got a couple of Guru Meditation errors. Not always, but often enough to become paranoid. I removed the memory expansion and did not get any errors at all. I inserted the memory again and I started getting errors again.

Some of the errors I got:

I got this error when I booted the computer without a floppy in the drive. Not sure, but it might be 'illegal instruction'.
00000004.OOCO1570

And I got this when I was loading a game. The code indicates 'free twice'.
81000009.265F48F1

The memory expansion is of model HE500 and appears to include a clock.

Is this an indication of faulty expansion memory, and if so, how can I do a memory check to verify the integrity of the memory?

Thank you for your help.

Your clock battery is leaking acid everywhere and destroying the molecular cohesion.

I feel like we are having a star trek conversation when you said "destroying the molecular cohesion." :biglaugh::biglaugh:

His Neutrinos are leaking too.  And he is now heavily irradiated.  He will probably grow a 3rd eyeball or develop ESP or turn blue or some other mutation any day now. :laugh1:

If he was to reroute power from DF1: DF2: and DF3: into the motherboard then it might start working again.  Or replacing the power supply could fix the problem.   It might be old and weak.
