Yeah, i figured the slow ram is actually the card, that's whats puzzles me.
It's weird because my system hasn't changed at all, just an accelerator swap. The old card was a 40mhz 68030 with MMU, the card had memory restriction of 32mb, hence the reason i bought your ACA witch is much faster than my old card, so that's good.
I will run on the a1200 PSU for a few days to see if it's stable, i'll keep you posted. I don't feel like sending card back and forth, shipping isn't very cheap.
Ok so we know its not a heat issue due to an overclocked cpu.
I am unable to test ram
Testing chip 2mb passed!
Testing Slow 1mb passed!
Testing Fast 126mb system hangs.
This is with Systest 1.2 but other tools like Memtest 020 fails as well, i guess the board has to be returned to AmigaStore 
Any idea why AIBB can't determine the CPU type? Never had this with my old 68030
I am now on an original a1200 PSU, running memory tests, but no difference
Display More"beefy" is not what you're looking for. You need proper regulation with low ripple, and only the vendor of the PSU knows if the 5V rail is really an individually-regulated rail.
For most ATX power supplies, the 12V rail is the main regulation rail, and 5V has severe stability issues if 12V is mostly unloaded (which is the case in your system). The e-Matrix card is a pure 5V design that may work if there's a drop below 4.8V, but the ACA1233n is a 3.3v design with regulators that require a 5V rail that's stable above 4.85V at any time.
I trust that the memory test tools are all fine, but I'd like to see how the system performs with an original Commodore power supply. Since you don't have much else in the computer, the original 3-amp PSU of the A1200 will do just fine.
Yes, the silver sticker that says "warranty" has the warranty ID. It's case-sensitive, so upper/lower-case makes a difference!
I tried 2 original Commodore PSU's. a a500 and a late a1200 psu.
I noticed something new just now.
When i start AIBB v6.5 i get a popup with this text:
Unable to firmly determine the difference between a 68030 or 68EC030 on this system.
Two buttons to select what CPU i have.
This is weird, i never had this issue before with my 68030 50.
