Earlier this week, we confirmed that MSI was bringing Resizable-BAR (AMD Smart Access Memory) support to AMD's Threadripper platform. Now, we can also confirm that MSI will soon be bringing this support to Intel's Core-X platform.

From what we have learned, MSI will soon be releasing a BETA BIOS for their latest X299 line of motherboards. The main update within the BIOS is support for the resizable-BAR function which "enhances GPU performance including AMD Radeon RX 6000 series & NVIDIA RTX 30 series". Just like the AMD Threadripper 'TRX40' platform, this BIOS will be an unofficial release but offer BAR support on Intel's HEDT platform.
