MSI has unveiled a new performance-enhancing feature for its AM5 socket motherboards to improve DDR5 memory latency. Some latency issues that emerged following AMD's AGESA 1.2.0.2a microcode update, which added support for AMD's Ryzen 9000X3D processors, are now fixed. MSI has baked in its BIOS tuning to develop a new "Latency Killer" feature, which can be found in the advanced menu section, specifically within the overclocking submenu in BIOS of MSI X870E/X870 gaming motherboards like MEG X870E GODLIKE and MPG X870E CARBON WIFI. Users have three options to choose from: Auto, Enabled, and Disabled. While the default behavior of the Auto setting remains unclear, it is believed to be initially disabled to ensure system stability.

Recent benchmark testing of Uniko's Hardware using AIDA64 has demonstrated promising results, showing an eight nanosecond improvement in memory latency when the new feature is activated. The test was conducted using a Ryzen 7 9800X3D processor paired with an MPG X870E Carbon WiFi motherboard and DDR5-8000 CL38 memory, running in High-Efficiency mode at its maximum preset. Some Reddit users with AMD Ryzen 7 9800X3D on MSI Tomahawk X870 reported seeing 10-12 ns improvement from enabling the "Latency Killer." MSI motherboards complement its Latency Killer feature with additional memory optimization tools in the BIOS, including EXPO / A-XMP profiles, Memory Try It presets, High-Efficiency Mode, and comprehensive manual overclocking options for enthusiasts seeking maximum performance.

MSI has released a brief statement regarding the recent issue of a burned AMD Ryzen 7 9800X3D on the MSI Tomahawk X870 motherboard. The issue was reported over at Reddit, showing both burned CPU and socket, and currently it seems to be an isolated incident. MSI is stepping in to investigate the issue and has released a brief statement.

"Recently, we received a user report indicating damage to an AMD Ryzen 7 9800X3D processor on an MSI MAG X870 TOMAHAWK WIFI motherboard. At MSI, we are fully committed to the quality of our products and have begun investigating this incident. Additionally, we are working closely with AMD and are in contact with GamersNexus, which is independently investigating this incident. We will continue to provide updates as the investigation progresses," said MSI in its official statement.
