AMD will soon be releasing more AGESA updates for Ryzen

In a new Ryzen community update, AMD has announced that they will soon be releasing more AGESA updates for Ryzen, which will reduce memory latency by 6ns, fix the FMA3 workload bug and fix the "overclock sleep bug". 
AMD's Generic Encapsulated Software Architecture (AGESA), is a protocol that is used on AMD64 mainboards to initialise the system. This software is responsible for the initialization of CPU cores, memory and HyperTransport controllers, which should mean that this new microcode will improve things like DDR4 memory support and fix some minor CPU issues. 
It has now been announced that AGESA version for Ryzen will be releasing to motherboard partners soon, with BIOS releases including the update arriving in early-mid April. This new microcode update will include some major updates, including memory latency improvements that could have a noteworthy impact on performance.

BIOSes based on this new code will have four important improvements;

  1. 1. We have reduced DRAM latency by approximately 6ns. This can result in higher performance for latency-sensitive applications.
  2. 2. We resolved a condition where an unusual FMA3 code sequence could cause a system hang.
  3. 3. We resolved the “overclock sleep bug” where an incorrect CPU frequency could be reported after resuming from S3 sleep.
  4. 4. AMD Ryzen™ Master no longer requires the High-Precision Event Timer (HPET).


One of the most noteworthy changes with this update is the 6ns reduction in memory latency, which should have an impact on certain latency-sensitive applications. The impact of this change in day-to-day usage remains to be seen, though we certainly look forward to finding out how this update will impact Ryzen's overall performance. 

AMD has also announced that they are planning to release further AGESA updates in May, which will focus on overclocked memory support, perhaps allowing 3600MHz memory to function on the platform.

6ns for memory? Will it really help all that much?Quote

Well from what I had seen during our testing, in AIDA 64 the Ryzen memory latency was around 90ns when using 2666MHz memory, but about 65ns when at 3200MHz.

Latency may not be the whole picture, but every little helps and it could be part of the reason why Ryzen loves fast memory.

This is something that will not have much of an impact in things like Cinebench, but could help in certain use cases.Quote

They did a pretty good job so far with the 1002 they released today. I'm excited to see what else they do.Quote

Maybe those 6ns are gonna help with better RAM speeds across the board and stability.Quote
