AMD Readying AGESA 1.0.0.7c for AM5 Motherboards
According to a post by @g01d3nm4ng0 on Twitter/X, we now know that AMD is readying yet another AGESA update for AM5 motherboards. The new version is, based on information from our own sources, a minor update to the current version. As such, AMD will be moving from 1.0.0.7b to 1.0.0.7c. @g01d3nm4ng0 didn't reveal any details of the new AGESA apart from the screenshot below, but we asked around and managed to find out what the new AESA addresses.
The update is specifically for those with Samsung DDR5 memory in their AM5 motherboards and it addresses multiple memory related stability issues. We weren't given the full details as to what those are, but there have been some reports about there being issues specifically with Samsung DDR5 memory in some AM5 boards and hopefully this will solve all those problems. We don't have a release time frame for the updated AGESA, but with 1.0.0.7b barely out the door, it might take a few weeks before this one makes it through all the internal testing at the motherboard makers.

If I had known that Zen 4 would have so many issues to still iron out when I first bought my parts, I'd have waited a little bit longer as well.
Doesn't mean anyone is doing something out of spec, it could simply be something AMD discovered that they had missed or was given some new information that hadn't arrived in time for the previous release.
Keep in mind that although JEDEC sets the specs on how each release of DRAM is supposed to work, it doesn't mean the implementations by each DRAM manufacturer is identical, as it's based on their knowhow, nodes and previous generations of DRAM, so there will be small differences and AMD, Intel etc. has to work around those.
Also, the previous release was about higher memory clocks, outside of JEDEC spec, so this is most likely related to that.
I'm a fan of Hardware Unboxed on YouTube and each of Steve's videos mentions a specific G.Skill kit that he uses in all of his AM5-related benchmark videos. I figured that if he uses that specific kit, I should too. And so, I bought that kit and what do you know? No memory training issues. No having to reset BIOS. Nothing of the sort. Rock-solid stable. I enabled EXPO and away I went.
Works flawlessly even OCd to 6000mhz.
Worked flawless with previous BIOS versions since PC first assembled a few months ago, too.
Whether I upgrade to Zen 5 will depend on not only performance compared to Arrow Lake, but if they have ironed out all the kinks with AM5. I don't mind a little slower if it's rock solid. Hopefully with faster memory being unlocked now for AM5 when Zen 5 comes out with it's rumoured DDR5 6400+ support, memory issues will be a thing of the past.

Description:
- AGESA ComboPI 1.0.0.7c updated. - Mitigate security issue. - Improved DDR5 memory compatibility. - Improved ACPI S3 issue.
as of 1007b, you need to either have both on (and incur the latency penalty that Power Down Mode has), or disable both and suffer excruciating boot times.
I don't have first hand experience with Zen1, but as far as I understand, it was stable using standard JEDEC profiles. The trouble came that in order to extract the maximum out of Zen, memory needed to be overclocked. That's where trouble started, especially since AMD's XMP was nowhere in sight.
And yes, lower is better.
