To confirm, the card is most definitely inserted the correct way and located correctly in the front case card holder groove. As far as I am aware the card cannot be inserted incorrectly. I have checked online photo's of other peoples rigs to confirm this also.I have no mediator or anything like that. I have been in contact with AmigaKit and waiting to hear back from them. Thought I would check this forum in the meantime in case anything else can be thought of.I thought about removing the Fast RAM from the motherboard too but haven't done so yet. Is this necessary? Nothing in the install instructions seem to suggest so but I could certainly give it a try.
I tried it anyway without the Fast RAM SIMMs installed and still not working, same red error screen saying the card is defective.I also went over all connectors and re-cleaned them all and reseated everything and tried the card in all different slots and still made no difference.I had a thought and probably should of mentioned this earlier but didn't think about it at the time, I have an overclocked 3640 processor card to 33MHz. I had a very strange issue with this overclock mod because a reroute is required from the clock delay module on the card but I could never get the machine to boot with the reroute. I ended up getting the machine to work with a very small length jumper wire that reverts it back to the stock configuration and assume the small wire is adding a very tiny delay enough for everything to work. I have seen no other problems and the machine is extremely stable and like I mention, my other cards work in the Zorro slots with no issue. Could this be causing an issue with the BigRAM card? I could revert back to a stock 25MHz and try that but my oscillator is soldered direct to the cpu card and would be a bit of a pain to swap over. I should of used an IC socket but didn't have any at the time and was feeling lazy.
