ASUS releases beta beta version with Resizable BAR function for Z490 motherboards – computer – news

ASUS has released a bios that adds Resizable BAR support to various motherboards with Intel Z490 chipset. Resizable BAR is also referred to as ‘Smart Access Memory’ by AMD and was initially only supported on AMD motherboards. Intel itself has not yet reported on support for this feature.

ASUS has quietly released bios version 1002, one editor noted from Tom’s Hardware. This bios version became released on Friday and is currently in beta phase. ASUS does not add a changelog to the bios update, but Tom’s Hardware confirms that the update adds support for Resizable BAR and Above 4G Decoding, among other things. Before that, the tech site used a Maximus XII Apex, although the update has become available for several ASUS Z490 motherboards, according to Tom’s Hardware. It seems to be mainly about higher positioned motherboards.

The website states that it is unclear whether Resizable BAR also actually works on the motherboard in combination with AMD’s RX 6000 GPUs. It is also possible that this is just preparation for future official support.

AMD already introduced Resizable BAR support with the release of its Radeon RX 6800 graphics cards. The company did this under the name Smart Access Memory, which for the time being only works for Ryzen 5000 CPUs in combination with RX 6000 video cards. However, this function has been included in the PCIe standard for some time, and therefore in theory also works on Intel motherboards and on older AMD platforms.

AMD has already stated that it wants to partner with Intel and Nvidia to support this feature on their respective Core CPUs and GeForce GPUs in conjunction with AMD’s products. Nvidia has already confirmed it is working on Resizable BAR support. It is striking, however, that Intel itself has not yet said a word about this function, despite the released bios update from ASUS, which thus adds the function to a motherboard for Intel CPUs.
