Mistakes

Montage M.2 SSD first, putting in the tiny screw is hard if it’s already in the case.
The Antec case ships the screws etc. in the hard disk slot, takes a bit to find.
Next time, order between 0 an 6AM to save shipping costs.

Base configuration

BIOS (press DEL to enter):
- BIOS Version: E7B89AMS.200 (had RDRAND fix afaics).
- Update BIOS to E7B89AMS.230 (extract zip to a FAT32 USB stick).
- move up legacy boot options
- enable IOMMU, enable SVM (for KVM)
- enable Cool’n’Quiet for acpi_cpufreq to work

Partitioning:

/boot: 2GB ext2

/: ZFS

zpool create -o ashift=12 \
     -O acltype=posixacl -O canmount=off -O compression=lz4 \
     -O dnodesize=auto -O relatime=on -O xattr=sa \
     -O mountpoint=/ -R /mnt \
     rpool /dev/disk/by-partuuid


zfs create -o mountpoint=none -o canmount=off rpool/ROOT
zfs create -o mountpoint=legacy rpool/ROOT/void
zfs create -o mountpoint=/home rpool/HOME
zfs create -o mountpoint=/home/leah rpool/HOME/leah

xvoidstrap /mnt base-system zfs grub

Benchmarks

Building Linux 5.2.16 (make defconfig && make -j17) takes 1:20.
Power Usage (Voltcraft Energy Check 3000):
- max during boot: 70W
- idle console: 35W
- ordinary slight usage: 60W
- all CPUs 100% during compilation: 140W

Tweaks

Need to enable XMP in the BIOS for fast RAM speeds.
Tweak fan control to only use 90% of fan (much more silent, ~2600 RPM max).
Add blacklist amd64_edac_mod to /etc/modprobe.d/blacklist.conf to avoid spurious warnings that I don’t have ECC ram.
