Performance is a bit worse than I hoped, I imagine this is due to XMP being disabled. Not the end of the world but it would be nice to have. I'm also not sure if resizable bar is an enabled or not, I don't see it as an option.
What are you comparing performance with? Have you benchmarked with MSI Firmware before flashing Dasharo? Need more data.
Since you are using a 12600K, I assume than you're talking about CPU performance. For THAT particular model, it is rather handicapped because Dasharo runs by default AC/DC CPU Loadlines @ 170 mOhms whereas MSI runs it @ 80, and there is a significant CPU performance difference there due to the higher power consumption causing it to drop out of the fastest Turbo clock speeds earlier (MSI can hold it out unlimited). I have benchmarked that cause I have the same Processor: https://github.com/Dasharo/dasharo-issues/issues/173#issuecomment-1193354034 But you will need to wait a new version before you get manual controls for those values.
The Crucial CT8G48C40U5 modules seems to be JEDEC standard and not support XMP at all: https://www.crucial.com/memory/ddr5/ct8g48c40u5 They will be downclocked based on Alder Lake DDR5 population limit. 2 DPC Single Rank should be 4000 MHz. decode-dimms returns NO output if it appears than the DIMM SPD checksum seems to be broken, it even refuses to acknowledge that there is modules like that installed. Here you have a DDR4 example where decode-dimms refuse to detect some PNY modules in different configurations, but detects fine some Kingston ones: https://github.com/Dasharo/dasharo-issues/issues/158
ReBAR is unavailable, Dasharo currently works with the equivalent of Above 4G Disabled and ReBAR Off. But Linux amdgpu drivers are capable of resizing BAR and forcing Linux to reallocate MMIO on their own, albeit no one benchmarked than as far that I know (BAR0 gets resized but BAR2 stays at 2 MiB vs 256 with Firmware ReBAR).
Thank you for the additional information! Unfortunately I don't have benchmarks from before, I really should have taken some. Overall I would consider it working as well as any other motherboard I've tried, I didn't mean for my notes to seem like a bug report, just my subjective experience as a user. The main thing I wanted to document is the 6700xt working without issues, which I haven't seen listed in the HCL before.

Other Notes In general everything seems fine. A few notes about my own setup:
Thanks for the hard work put into this project!
