Interesting. Maybe it was your firmware version or settings then. Good to hear you no longer have the problem.

Who upgraded your CSPPC for you?
Amiga 4000T: CSPPC 604e@233/060@50 146MB RAM/CVPPC/Mediator/Radeon 256MB/Realtek 8029AS/TerraTec Solo1-N/Picasso IV (Paloma Pablo Concierto)/Deneb/ZorRAM 256MB/Indivision AGA MKII/OS4.xBETA/OS4.1u4/OS3.9BB2
AmigaONE X1000: Nemo 2.1 PA6T-1682M@1.8 2GB RAM/Radeon HD 4770 512MB/Catweasel MK4+/Audigy 2 ZS/Realtek 8139D/OS4.xBETA/OS4.1u5

someone did an upgrade from my csppc to 366 mhz cpu and scsi problem is also gone.. :D
im happy now..

thx for help
You are very lucky your SCSI still works reliably under OS 4.x after upgrading your PPC cpu. I had stachu upgrade mine as well, probably to the same CPU as yours, and now my SCSI locks under OS 4.x. It was an older CS PPC revision I gave to him - perhaps I should have given him a newer one to do. There were several revisions of the CSPPC board and some of the chips on it that are not documented very well or even visible to see.

I also got a 350MHz 604e CPU and having cybppc.device lock-up issues in 4.1 that I don't see in OS3.x. I haven't resolved anything yet but have tried to do some research on the net:

There seems to be a few varieties of the CPU and a good summary here:
https://www.okqubit.net/ppchikaku.html

Datasheets are here:
https://www.nxp.com/products/no-longer- ... tation_Tab

1) XPC604ERX200PE part number is my original one from Motorola and looks like it is a 9v version. Interesting note is that it looks like phase5 was using "Pilot Production Prototype" chips since the part number has an "X". (see MPC604E2PNS.pdf)

PID9v-604e --> Core Voltage = 2.5V.
DRVMOD0 = low
DRVMOD1 = high


2) PPC604e3DBCG350E part number that I have now on my phase5 board is the IBM one and looks like is a 9q version.

PID9q-604e --> Core Voltage = 1.8V.
DRVMOD0 = high
DRVMOD1 = high

The DRVMOD bits seem to affect some timings...

In the "PID9q-604e" there is this mention: "Compatibility mode specifications are provided to support PID9q-604e use in existing designs."

Has anybody actually noticed any performance difference? I've switched between my 180 MHz and 350 MHz (now sold) and the subjective performance seems identical.

I haven't done any comparison but I would like to know that too.
