MSI has recently been generous to offer the AGESA 1.1.9.0 update for both its B550 and X570 motherboards to bring Resizable BAR support for older Ryzen processors as well as with NVIDIA Ampere GPUs. Now you will think, what is Resizable BAR support?
You will also think this feature is not exclusive to AMD’s latest Ryzen 5000 series processors and Radeon RX 6000 series GPUs? The answer is no; yes, both of them work well with the feature, but AMD doesn’t own the feature; it’s just their Smart Access Memory, or SAM uses this Resizable BAR feature on supported motherboards.
Resizable Base Address Register has already been available with PCIe gen 3 specifications, and kudos to AMD to make everybody talk about it now. As of now, AMD GPUs will take advantage of this on a number of motherboards and the processors using it.
Although AMD’s SAM implementation is far more stable, NVIDIA is also said to work on this as a PCIe Express feature. However, the wide usage of this feature on many motherboards of both AMD and Intel platforms is yet to take some time.
The advantage of this is, when turned on, games enjoy extra framerates and offer up to 10% higher frame rates in games like Assassin’s Creed: Valhalla or boost minimum framerates at 4K max settings in heavy games like Red Dead Redemption 2 and others.
MSI’s update proves one by one that almost all major motherboard makers will be enabling Resizable BAR support in days to come, giving you an extra performance boost at no additional cost.
