AMDs Ryzen 7000 “Zen 4” CPU and the corresponding AM5 platform does not go through a smooth launch plan. On August 29, several rumors surfaced that the chips might face a short delay.

AMD Ryzen 7000 “Zen 4” Desktop CPUs and AM5 Platform Experiencing Delay When Installing BIOS Issues

AMD though confirmed As it will host an official launch event on August 29, actual sales won’t open until a few weeks or even a month later. We used to informed according to our exclusive, the launch could be pushed back to September 27, the same day as Intel’s 13th Gen Raptor Lake CPU launch.

Now there are more rumors (I don’t know if it’s appropriate to call them rumors now considering the origin of these reports. current reviewers and also several insiders who work closely with motherboard manufacturers who know what’s going on) that the launch is indeed delayed and that AMD has been asked to sign a new NDA more or less confirming the new launch date.

Published by the following nApoleon, Chiphell’s resident tech reviewer and editor on the forums:

One thing I want to make clear is that the August 29th event will be an “Open” and not an actual “Launch” which is always meant to be in September. The release was previously scheduled for September 15 but it was recently moved to September 27. now we know that the main cause of this delay is related to the BIOS. Like every Zen generation, the BIOS is an important part that sees different versions for improved CPU and memory support. This time, like the AM4 platform, there will be several versions before and after the launch.

So far, we have heard that there have been at least 7 AGESA BIOS revisions in total, starting with Patch A and ending with Patch G. The latest BIOS was released this month and things aren’t going well with it either.

Gigabyte has listed AGESA Patch D (old BIOS) for the X670E AORUS Master motherboard.

Previously, motherboard manufacturers were expected to release AGESA BIOS v1.0.0.1 Patch D with their motherboards at launch, but this no longer appears to be the case as the older BIOS was not optimized enough for AMD Ryzen 7000 processors. AM5 motherboard platform that also supports EXPO DDR5 memory. So there are reports that the official BIOS at launch will be v1.0.0.2, and we’ll see future versions of the BIOS moving forward as well.

For those wondering what these BIOS issues are all about, there are several fixes, each focusing on different optimizations, fixes, and support. The current SMU has been updated to 84.73 and supports AMD Ryzen 7000 16-core and 12-core CPUs, while the former added better OC capabilities for DDR5 memory.

The list goes on, but it’s not just specific to memory or CPUs. As mentioned earlier, the AGESA BIOS firmware will be updated on a priority basis before and after the launch of the AM5 platform, so instead of sales starting now and users going through the arduous BIOS update process, AMD has delayed the launch. history for a smoother and better first-time experience for users on the next-generation platform.
