    I removed the Buster-09, soldered on a socket and inserted a Buster-11. Now everything is working perfectly. BigRamPlus is working and my zz9000 card i working. Haven't tried both of them together though since i've read that this is not possible.

    So the solution was to upgrade to Buster-11.


    I have tested this with my A3640 and A3630 card.


    As a curiosity, i can confirm that when using Buster-09 with my A3630, i managed to get BigRamPlus to work if i put it in the second top most socket on the daughterboard. Doing the same with my A3640 resulted in crash.

    I've read that some ZIII bursts stuff are disabled when using the 030 card, so this is maybe why it work. Wild guess :)


    Anyway, after upgrading to Buster-11, there are no more problems and i can use the card in any socket.

    Ok, ZZ9000 finally arrived and i can confirm that i have the same issue with the ram with this card. So sadly :) there is something wrong with my hardware. The RTG is working ok, only the ZIII ram expansion is malfuntion, so exactly the same problem as with the BigRam.

    I noticed that my Buster is Rev-09, but the exact id is 390539-09 45-SUPER BUSTER. This is according to BigBookOfAmiga fitted in an A3000.

    Could there be a problem with this version? Is it tested with this version?


    Anyway, thanx for you help and please return the card to me (i'll pay for shipping of course) as it should be working perfectly.

    The installation is OS 3.1.4 (with 3.1.4 roms) with update 3.1.4.1 installed. On top of that BestWB 1.3. MMU.library 46.20, 68040.library 46.3.

    Copy v45.4

    My HD is a 2.5 320GB Sata disk which is connecteed through an SATA to IDE adapter.

    Filesystem if PFS3aio 19.2

    Buster-9



    I have ripped some music to CDDA to disk and i start copying these files to ram. Each file is about 45 mb.

    I have also tried to just drag the workbench disk onto the ram disk.


    Could there be some issue with Zorro III only? I'm waiting for my zz9000 card, so then i can verify my Zorro III (Should show up in may).

    All of my Zorro II cards works perfect.

    I have tested the card on another stock Amiga 4000/030 (Perfect condition), and the result was the same as on my machine.


    Amiga test kit tested the ram ok, but as when i boot into workbench and tried to copy files (entire Workbench disk) into ram, the machine crashes when the BigRam memory is used. Sometimes recoverable alert, sometimes instant reboot.

    Sometimes though, it was able to copy some data into ram before it crashed. For instance after 10 mb of usage.

    Tested it many times on this machine and it crashed every time.

    So my assumption is that there is something wrong with this BigRam card.

    Ok so far no luck.


    My A4000 is not overclocked (25mhz).

    - Cleaned everything with alchohol

    - Tested with kickstart 3.0 and 3.1, booted from workbench disk.


    - Tested the computer with all kind of tests with DiagRom 1.2.1 (all motherboard RAM ok)

    The Bigram card is also found correctly by DiagRom, but DiagRom could not be used to test the zorro ram.


    - Tested all ram with Amiga Test Kit 1.16, and there i could test the BigRam and my zorro ii ram, and no faults were found. It ran for at least 24 hours.




    As soon as i try to copy data in the workbench or speedtest the ram, it crashes.

    A little wierd that the test kit managed to test the BigRam without any issues.


    I can't find any fault with my computer, and i haven't had any issues with it so i guess i must try to test this card in antoher A4000 to see if the trouble is recreated there.


    Could a new crystal oscillator do any difference?

    Hi, just received my BigRam+ 256mb, but the system crashes as soon as it tries to access the memory.

    Everything boots up fine, and show 290MB ram (256 + 16 + 8).

    When i start to copy a 50 mb file to ram, the system crashes when it starts to use the 256 mb ram. (Guru 800004)

    Have tried to all zorro slots with same result.


    The system is A4000D OS 3.1.4 040 25mhz (A3640). Buster-9

    Original Amiga daughterboard.

    Everything is recapped.


    Have also

    GVP SCSI HC+8 II with 8 mb ram and AD516 sampler card which is working flawlessy with this daughterboard.


    Have removed all cards and tried with only the BigRam card inserted.



    If i try to speedtest the memory area for the 256mb ram, it crashes also.


    Any suggestions?
