MSI has rolled out an exciting new feature called Latency Killer for its AM5 motherboards, specifically aimed at addressing latency issues introduced by the recent AGESA 1.2.0.2a update. This update initially caused a slight increase in memory latency on DDR5 setups for the X870 and X870E motherboards. Despite this being a subtle change, MSI’s latest addition promises to bring memory latency down without requiring users to downgrade their BIOS versions.
The Latency Killer feature, now found in the BIOS settings of motherboards like the MSI MEG X870E GODLIKE, comes with three operational modes: Auto, Disabled, and Enabled. Initial tests have shown an impressive reduction in latency—down by about 8 nanoseconds. For instance, a test conducted using an MSI MPG X870E Carbon Wi-Fi board demonstrated reduced latency from 74.7ns to 66.7ns with specific settings.
What makes this even more interesting is that users reported this improvement using the same AGESA 1.2.0.2a BIOS, indicating that no additional downloads are necessary. Instead, users can leverage the latest BIOS with the Latency Killer feature to reclaim optimal performance effectively. This approach ensures a seamless experience, bolstering performance without reverting any updates.
However, there is a trade-off to consider. While Latency Killer optimizes memory latency, it may have a variable impact on CPU performance. The feature’s description hints at a possible decrease in CPU performance, though the exact extent is uncertain. This suggests that memory gains might come at the cost of CPU efficiency in certain scenarios. The perceived impact would likely vary from user to user, and further testing will provide more clarity.
Interestingly, the improvements in latency have been shown to significantly boost AIDA64 benchmark scores. Nevertheless, users might not notice a tangible change in ordinary applications or gaming.
As more users experiment with Latency Killer, further insights into its effects on overall system performance are anticipated. Enthusiasts and IT experts alike are watching closely, eager to see how MSI’s latest feature will balance the eternal juggle between latency and CPU performance.
