Hi,
I also had a problem with cpu clock frequency
ARPL v1.0-beta11a --> DS3266XS+ --> DSM 7.1.1-42962-Update3
Asus P8P67 B3 IvyBridge --> 3570k@3.40GHz --> RAM: 16gb 1600mhz --> HDD: 1-WD SSD 500GB NAS -->

Realtek PXE Oprom: Disabled
PowerConsumption in first boot 92.4W (in proxmox and 1-128gb ssd and 2- 500gb hdd) in idle consumtion 65W
At first, I did the transition from TCRP 0.9.4.1 because I had a problem with update 3.
On ARPL it installed Update 3 very nicely, but I had a problem with CPU Clock Frequency and it was showing me 1.6Ghz and 6 cores. After applying ch_cpuinfo the CPU information was good, but the 1.6Ghz problem still remained. After many attempts failed (in geekbench5 I had a score similar to other i5-3570k) I disabled in Bios C1E, Enhanced Intel SpeedStep Technology, RAM with XMP to Manual and hard, disabled bluethoot, 1394, Marvell and Realtek PXE Oprom.
I created from scratch Loader --> LKM: dev and all modules include to config xD --> Build --> Boot and Working!
I test reboot DSM, shutdown and running directly boot and working very good!
