EVGA has recently released new BIOS updates for their X299, Z590, and Z490 motherboards enabling support for the PCIe Resizable BAR feature. Resizable BAR is an optional feature of the PCIe specifications which allows the CPU to access more GPU memory theoretically offering greater performance. AMD released their implementation of Resizable BAR with Smart Access Memory on Radeon RX 6000 Series graphics cards. NVIDIA responded by announcing plans to add Resizable BAR support to their RTX 30 series graphics cards starting with the RTX 3060. This new BIOS update for recent EVGA Intel motherboards will ensure that you can take full advantage of the latest graphics cards. When we tested AMD's Smart Access Memory with the Radeon RX 6800 XT we saw an average performance improvement of 2%.
