I have the 3900x and the Master as well. How did you guys hit the advertised boost clocks? I only hit 4.5 on 1 core
which board and which bios version . how about cooling ? custom water cooling ?
I am running Aorus Xtreme, and I am water cooled with a custom loop.
In Bios I have my memory clock and timing manually set (not XMP). FCLK is manually set. Vcore is set to "Normal" and PBO is disabled. My BCLK is set to 103Mhz.

Following up on our conversation of NMVe Raid using SSD's connected through the chipset slowing down PCIe 4.0 SSD performance (which is connected directly to the CPU), in Bios I have the following:
SATA Mode: AHCI
NVMe RAID: Enabled
SATA Chipset Ports: Disabled
Again the gigabyte SSD is only reading at 3800MB/s, well shy of the 5GB/s it is supposed to reach. If I benchmark without NVMe raid enabled I get the full speed.
Do note that from my experience, when I enable NVMe Raid and install Windows, even though my main SSD is not apart of the raid array it still uses the NVMe Raid drivers. If I disable NVMe Raid in bios, Windows will no longer boot. So when testing I did have to re-install windows to benchmark the gigabyte ssd without raid.
On another note, I have two Radeon VII GPU's installed. On the F3i bios, for some reason the second GPU is treated at the "Primary" card regardless of what is set in the bios.
The beta bios F3L fixes this issue but for some reason when I use this bios I have major issues with GPU performance. Normally my GPU runs around 2100Mhz (overclocked) but on F3L it for some reason the GPU clocks can barely sustain 1300Mhz and jumps around from 900 to 1300Mhz constantly. This happens regardless of if the card is OCed or stock. I have also tried re-installed the video drivers as well. Speaking of video drivers, when I run F3L and go to install drivers, I get that warning that the driver publisher could not be verified, which does not happen on F3i.
Now I know these problems do not sound like that should be connected to the bios at all, but I swear I must have spent like 3 hours last night flashing between F3i and F3L and was able to consistently repeat the issues above.
