MSI has announced that it is adding resizable BAR support to all of its Intel 300 series motherboards. MSI has released BIOS firmware updates for its Z390, H370, B360, and H310 chipset-based motherboards and this latest BIOS Firmware adds BAR support to these motherboards.
MSI announced resizable BAR support for over 50 of its Intel 300-series motherboards. MSI previously announced that it will be bringing Resizable-BAR to its fleet of Intel 300-series motherboards. And now, the BIOS firmware for over 50 motherboards is live. MSI says that it is working on getting more motherboards support for the feature in the near future, especially the Intel Z370 lineup.
According to MSI, Resizable-BAR will enhance overall GPU performance for NVIDIA GeForce RTX 3000 series and AMD Radeon RX 6000 series graphics cards in titles that could make use of the feature. Gains of around 10-15% should be expected in titles that can utilize this feature. MSI has introduced this feature in its entire portfolio of 300-series motherboards based on the Z390, H370, B360, and H310 chipsets.
Currently, all MSI 300 series motherboards except the Z370 have received support for resizable bar support. MSI says that it is also working to add Resizable-BAR support on its Z370 lineup of motherboards. There are still a lot of users currently running the Z370 platform with Coffee Lake CPUs.
Resizable Bar is a virtual tunnel that is generated between the graphics card and the processor. This allows the processor to access the VRAM memory directly and conveniently.
Using Resizable BAR, all Tasks performed by the processor are stored in the VRAM. The processor loads the data into the VRAM and tells you where this data is. So, the GPU has them accessible at all times when it needs them. Therefore, we eliminate the latency generated by asking the processor for the calculation, to look for it in RAM and to deliver it to the GPU.
If you have a supported MSI 300 series motherboard, you can check out its page on MSI’s website to download the currently beta bios which will add support to your motherboard.
