ASRock has released a beta BIOS for the Z490 Taichi motherboard with support for a technology that allows the CPU to access the entire video memory of discrete graphics accelerators at once. ASRock’s technology is called Clever Access Memory. At its core, it is the same technology that AMD introduced for motherboards based on the 500 series chipset – Smart Access Memory (SAM).
AMD’s SAM technology can only work with Radeon RX 6000 GPUs at this time, as only they can take advantage of the Resizable BAR (Base Address Registers) feature that is part of the PCI Express interface specifications. In the future, NVIDIA will also add support for Resizable BAR for GeForce video cards.
According to the resource Wccftech, enabling the Resizable BAR feature in the beta BIOS for ASRock Z490 Taichi does indeed improve gaming performance. The source tested in Shadow of the Tomb Raider and Assassin’s Creed Valhalla.
The test gaming system used an Intel Core i7-10700K processor, two DDR4-2666 memory modules and a Radeon RX 6800 XT graphics card. With the function active in the first game, performance increased by 3.3%, in the second – by 11.5%.
The source also provided screenshots showing how to enable Clever Access Memory in the beta BIOS of the ASRock Z490 Taichi motherboard.
