“Latency Killer,” a new BIOS option that MSI has developed to counter the memory latency degradation that was introduced with AGESA 1.2.0.2a—the BIOS update that added support for the Ryzen 7 9800X3D—has been tested and is capable of reducing DDR5 memory latency by up to 8ns on AM5 motherboards, according to screenshots that have been shared online. See below for the spot from UNIKO’s Hardware, which shows the Latency Killer feature under the Advanced menu of MSI’s latest BIOS for the MPG X870E CARBON WIFI motherboard, with Auto, Enabled, and Disabled options. “Enhances latency performance but could potentially reduce CPU performance,” a warning for the feature reads.

with fixes mobo vendors added, you dont have to flash back old agesa versions to get back the original performance.https://t.co/n5A8tODjxb pic.twitter.com/UFJB3dvSfk
