I have jumper 2 set high
I have no idea what that means, and J2 is only for disabling the RTC in an A500+, so it's not the jumper to change. I'd remove it for Rev. 5 or Rev.6, as there is no second 512k expansion on the pass-through connector of your A512.
J1 is the one that should be removed if you have the 1M chip ram modification in your Rev.5/6 A500.

J1 did the trick and all memory tests passed.
Thank you
