MSI to bring Resizable-Bar support for the X299 platform

MSI’s Resizable-BAR (AMD Smart Access Memory) is a well-known technology that takes CPU performance to the next level. It was confirmed earlier that the manufacturer is bringing the support of Resizable-BAR to AMD’s Threadripper platform.

But according to sources, MSI is also confirmed that it will be bringing this support to Intel’s Core-X platform. The OEM announced that it would soon be releasing a BETA BIOS for their latest X299 line of motherboards. The BIOS’s main update is support for the resizable-BAR function, which “enhances GPU performance, including AMD Radeon RX 6000 series & NVIDIA RTX 30 series”.

Before releasing the BIOS the resizable-BAR feature was tested on the MSI MEG X299 Creation motherboard, the Intel Core i9-10980XE ‘Cascade Lake-X’ 18 Core CPU & both, GeForce RTX 3090 & AMD Radeon RX 6800 graphics cards.

There are no performance metrics available as of now, but it is worth remembering that MSI is by far offering the largest support list for the Resizable-BAR (AMD Smart Access Memory) feature with Intel chipsets dating back to 300 series and AMD chipsets going back to 400-series in their support list.
