Latest AMD AGESA Update Brings AM5 1:1 Clock Ratio Up To 6400MHz

Latest AMD AGESA Update Brings AM5 1:1 Clock Ratio Up To 6400MHz

The recent AMD AGESA update, version number 1.0.0.7b has seemingly brought a big leap in Ryzen’s memory capabilities. This new microcode update has enabled some motherboards to push as high as DDR5-8000 (uncoupled), and under 1:1 UCLK:MEMCLK ratio the limit has been raised from DDR5-6000 to now DDR5-6400.

Overclocker Buildzoid mentioned this overclock is performed on an ASRock B650 LiveMixer motherboard – so there’s a good chance high-end X670E models can get a lot higher than this.

Various OEMs has posted their overclock results with the new AGESA, and it’s nothing short of impressive. Videocardz has compiled a list of motherboards from ASRock, GIGABYTE, MSI and ASUS, with MSI’s X670 ACE model running at a ridiculously fast DDR5-8200 speeds thanks to overclocked OLOy modules.

An ASRock engineer on Reddit has revealed the changes contained in the 1.0.0.7b AGESA update which provided much higher RAM speeds. One of them is something called “DDR5 Nitro mode” that allows for even more granular memory timing controls, which enabled higher RAM speeds as a result. There’s also a new setting that allows the user to change the behavior of memory training – a process which may take a few minutes to complete on first RAM install – to provide better stability in expense of longer training durations.

The engineer also mentions Ryzen 7000 chips can now achieve DDR5-6400 while retaining 1:1 clock ratio in some cases – which is crucial as 1:1 ratio provides the least latency and thus performs better in games. The AGESA update is currently rolling out to various motherboards, so be on the lookout for updates if you need that extra bit of speed boost.

Pokdepinion: Platform maturity is beginning to kick in – we should see some pretty good numbers on RAM overclocking on AM5 platforms.
