Thanks!

kldload imcsmb.ko:
imcsmb_pci0: <Intel Skylake Xeon iMC 0 SMBus controllers> at device 30.5
numa-domain 0 on pci5
imcsmb0: <iMC SMBus controller> numa-domain 0 on imcsmb_pci0
smbus1: <System Management Bus> numa-domain 0 on imcsmb0
smb1: <SMBus generic I/O> on smbus1
imcsmb1: <iMC SMBus controller> numa-domain 0 on imcsmb_pci0
smbus2: <System Management Bus> numa-domain 0 on imcsmb1
smb2: <SMBus generic I/O> on smbus2
imcsmb_pci1: <Intel Skylake Xeon iMC 1 SMBus controllers> at device 30.6
numa-domain 0 on pci5
imcsmb2: <iMC SMBus controller> numa-domain 0 on imcsmb_pci1
smbus3: <System Management Bus> numa-domain 0 on imcsmb2
smb3: <SMBus generic I/O> on smbus3
imcsmb3: <iMC SMBus controller> numa-domain 0 on imcsmb_pci1
smbus4: <System Management Bus> numa-domain 0 on imcsmb3
smb4: <SMBus generic I/O> on smbus4

But after kldload jedec_dimm.ko:
sysctl -a | grep jedec | wc -l
       0

Added to /boot/device.hints:
hint.jedec_dimm.0.at="smbus1"
hint.jedec_dimm.0.addr="0xa0"
hint.jedec_dimm.0.slotid="Silkscreen"

kldunload jedec_dimm imcsmb / kldload - nothing changed.
