Good to hear you got it going! A couple of random thoughts - the pbscsi seems to have a "Pseudo DMA" feature so my first guess would be that is overlapping the TF534 RAM address space That's unlikely because the 534 places the ram in the Z3 space. What is more likely is that the driver is...

Thank you for the many ideas you are great.
Unfortunately I have problems with my microscope I will upload it at the weekend.

You are right, I will swap the ram.
I will order the ones from Digi-key.
what do you think of these?

That should work fine.

Buying ram from Aliexpress is a bad idea, I recommend you get it from mouser/digikey instead.

Oh wow. This is either my card they resold or they are using the same serial numbers as me, either way it seems very concerning to me, other than the fact that as per usual they offer no support whatsoever. :( Terrible service either way. I really don't understand why people keep buying stuff there...

Who did you buy the card from? Check the serial numbers, the one starting with 1xxx are built by Chucky, the ones starting with 2xxx by me and 3xxx by supaduper. The reason I am asking is that it is your builder's responsibility to give you support, info/updates etc. Then you have the 3rd party one...

He's probably running the Beta firmware, and that's why it caps out at 75. Or a wrong version of the cpuspeed command.

IC NOT from the BOM: Mouser Part no. 771-HCT245PW118 not working as IC6. I didn't build this card, maybe a firmware problem? Or fault in the PCB? I use HCT on all of my 536s without issues, so I don't know why they don't seem to be working for you. Could it be a matter of a CF card adapter? Are you...

You should use Mouser Part no. 771-HCT245PW118
