I had some time to transfer my Big Sur SSD to the 800 G5/i7-9700. After configuring the BIOS, it booted without any changes and without any problems. Only difference I see is that the i7-9700 multicore performance is better. Otherwise, the unit seems identical to the 800 G4/i7-8700.
- CPU: i7-9700 (8-Core, No Hyperthreading, CoffeeLake, UHD630)
- Display: 3 x DP -> DigitalDVI
- Chipset: Q370
- Memory: 32GB (2 x 16GB) DDR4
- Wi-Fi: Intel (disabled in BiOS)
- 90W Genuine HP Power Supply
- Cost: $460 with shipping (base cost before I add 2 x M.2 NVMe SSDs and add 1 x 2TB SATA6 HD)
About This Mac
just updated to the newest HP bios....no problems so far...works great
I have found on my MacBook Pro 2020 that HPET is still in use by macOS in my System DSDT by just opening MaciASL and search for HPET.Note that my rig is running with HPET DISABLED via ACPI patch (HPET._STA=0 just like a real MacMini8,1). See my reasoning here. I'm not sure if this HPET setting affects these results. I also use RtcMemoryFixup.kext with custom rtcfx_exclude range (with CLOVER, I did not use "Fix RTC"). I also have both DDR4 memory banks populated (I have found that single-bank performance is less).
@GeraldB Take another look at your ACPI and your IORegistryExplorer. Let me know what you find. I suspect you're going to be surprised.
