AMD AGESA 18.104.22.168 Update Improves Ryzen DRAM Support
Ashley Allen / 4 years ago
AMD continues to tinker with its new Ryzen CPU platform, and its new update introduces support for higher DRAM memory clocks. The update, AGESA (AMD Generic Encapsulated System Architecture) 22.214.171.124, expands compatible memory frequencies up to DDR4-4000. The AGESA 126.96.36.199 update also reduces memory clock increments, which should be of benefit to overclockers.
AGESA 188.8.131.52 Update – A Boost For Overclockers
In a new community update, AMD says:
AGESA 184.108.40.206 officially adds 26 new parameters that can improve the compatibility and reliability of DRAM, especially for memory that does not follow the industry-standard JEDEC specifications (e.g. faster than 2667, manual overclocking, or XMP2 profiles).”
Keeping in mind that this is overclocking territory, manual or automated control of these parameters should nevertheless make it a little more straightforward to use DDR4-3200 modules—or faster if you have the talent!
Reduced Memory Clock Increments
AMD explains that, in addition to DDR4-4000 support, the increments between DDR4-1866 and DDR-3200 have been reduced to 133MT/s:
Added dividers for memory clocks up to DDR4-4000 without refclk adjustment. Please note that values greater than DDR4-2667 is overclocking. Your mileage may vary (as noted by our big overclocking warning at the end of this blog):
133.33MT/s intervals (2667, 2933, 3067, 3200, 3333, 3466, 3600, 3733, 3866, 4000)
Distribution of AGESA 220.127.116.11
AMD has already sent AGESA 18.104.22.168 to its motherboard partners. Therefore, we should expect BIOS updates from the likes of Asus and Gigabyte by the end of next month.
