After MSI has activated the open standard Resizable BAR alias AMD Smart Access Memory via BIOS update for HEDT mainboards with TRX40 chipset , ASRock follows suit and gives full VRAM access for HEDT CPUs on mainboards with chipsets of the series WRX40 and X399 and the huge socket TR4 free.
Resizable BAR for Ryzen Threadripper 2000
This is certain, also in HEDT Segment, AMD Smart Access Memory scales at least down to the Zen + architecture, because the four HEDT processors AMD Ryzen Threadripper 2990WX, 2970WX, 2950X and 2920X (test) are known to be based on this. Zen +, Zen 2 and Zen 3 have already been activated for the open PCIe standard Resizable BAR.
After the community from the ComputerBase- Forum Resizable BAR alias AMD Smart Access Memory (Benchmarks) with a wide variety of CPU and GPU configurations, Nvidia also announced a solution for full VRAM access at CES 2021 on and under Linux the feature continues to make progress. With a total of six BIOS updates, ASRock is making the start with processors based on Zen +.

Ryzen Threadripper 1000 also supports Resizable BAR
Like first tests of community Member ' Maxxx800 ' from theComputerBase forum, the first generation of the AMD Ryzen Threadripper (test) from 2017 also supports the open standard Resizable BAR aka AMD Smart Access Memory.
With an AMD Ryzen Threadripper 1950X on an ASRock X399 Phantom Gaming 6, the ComputerBase reader was able to activate the feature and thus achieved around 14 percent higher frame rates on his AMD Readon RX Vega in the role-playing game Cyberpunk 2077 (test) . The BIOS version P1.31 linked in the table was used.

Once again, community member 'Maxxx800' has tested his Ryzen Threadripper 1950X on a Zen basis with Resizable BAR and benchmarks in Shadow of the Tomb Raider made.
With activated AMD Smart Access Memory, the frame rates increase from an average of 71 to 77 images per using the WQHD resolution (1440p) Second, which corresponds to an increase of 8.5 percent.
The editorial team thanks community member “Maxxx800” for his benchmarks, which made this update possible.
