MSI is rolling out its latest BIOS for AM5 800 and 600 series motherboards, offering optimized support for CXMT DDR5 memory.
MSI Offers Optimized Support For CXMT's DDR5 Memory On Its AM5 800 & 600 Series Boards
As CXMT's DDR5 memory continues its push in China's domestic market, motherboard vendors are acting swiftly to offer optimized support for the latest modules and kits. MSI has now become the latest of the bunch to offer support.
The MSI BIOS spans its entire AM5 portfolio of motherboards, including the 800 series and the 600-series products. The BIOS has three main features, the first of which is the update to the latest AGESA PI-1.3.0.1b Path A, which is based on AMD's latest firmware, & the second is the aforementioned "Optimized for CXSH (CXMT) memory chip" support.
With the latest BIOS, MSI's AM5 motherboards will see improved support for CXMT memory, allowing a wide range of motherboards to hit speeds north of 8000 MT/s, as the motherboard vendor demonstrated a few days ago.
The new BIOS pushes CXMT memory from 6800 MT/s speeds to over 8000 MT/s, which is a big jump, but we are told that the support will vary with 2-DIMM designs offering much better capabilities than 4-DIMM designs. MSI's own tests show that 4-DIMM motherboards support 7200 MT/s, and these will continue to improve with future BIOS updates and better quality CXMT ICs.
TSME Support Now Unlocked With AMD Ryzen 9000 CPUs
In addition to CXMT's DDR5 memory support, the new MSI AM5 BIOS also re-enabled TSME Encryption, which was recently locked behind PRO Ryzen chips. After facing backlash, AMD decided to re-enable the feature on its DIY-focused Ryzen family, such as the Ryzen 9000 CPUs.
TSME, or Transparent Memory Secure Encryption, is a hardware security feature that encrypts everything stored in the system RAM using a key generated by the processor during boot. Unlike AMD's SME (Secure Memory Encryption, the TSME feature works automatically once enabled in the BIOS and doesn't rely on the operating system.
ASUS has already restored support for TMSE on its own motherboards, and like MSI, we can expect other motherboard manufacturers to do the same with their latest BIOS updates.
