Maybe I'm in the wrong place but I'm a newbe
When I look at std error output for open clati reports I see :

'AMD Accelerated Parallel Processing', device 'gfx1030', vendor 'Advanced Micro Devices, Inc.', version 'OpenCL 1.2 AMD-APP (3188.4)' and driver '3188.4 (PAL,LC)'.
40 computeUnits @ 2135MHz, memSize=3072MB, cacheSize=16kB, cacheLineSize=64B, localMemSize=64kB, maxWorkGroupSize=256.[/i]

The problem is that these parameters dont appear to match the RX6900 XT which 80 ComputeUnits, 128MB Cache, 16GB memory.

has the Open Cl for ATI been upgraded to see later later Radeon GPUs
Could this account CPU crashes when running larger GFN (ie 18 +)

Yes that is the driver I am using and the problem existed in earlier drivers. Its been a problem for a month or so with the then current drivers.
I thought it might be temp but have wound back MHz to max at about 2000MHz and allowed a little over voltage and it appears to run cool. Tried two different 1000w power supplies, - no difference, and MB Bios (Aorus X570) is latest. Also changed to run PCIe Gen3 instead of gen4 but again no difference.
Have run Furmark and other GPU stress tests but all pass Ok. I'm at a bit of a loss to know where to go next

Thank you for your insight.
Yes its a big step forward but only if I can get it stable enough to run GFN.
Last run it managed 3 x GFN18 before crashing the CPU on the 4th.
Each time I tweak another parameter and run again. Throttling the GPU back to about 2000Mhz seems to have made it a little more stable but seems to me that this is not an ideal solution(?)
This time its enabling the "Smart Access Memory" feature of newer AMD CPU/GPU combinations which I had thought was enabled by default on my MB but apparently not.

If all else fails I will just use it for the image processing it was bought for and run GFN 16 and 17 which it appears to handle OK
