AMD Ryzen 7000 “Zen 4” Desktop CPUs & AM5 Platform Delay as BIOS Issues Increase

While having AMD Confident It will have an official launch on August 29, with actual sales not opening for a few weeks or a month later. Earlier we reported Our exclusive has it that the launch could be pushed back to September 27th, the same day as Intel’s 13th Gen Raptor Lake CPUs.

Now there are more rumors (I don’t know if it’s even appropriate to call them rumours, considering how many of these reports are coming out. Real critics According to several insiders (who work closely with motherboard manufacturers who know what’s going on) the release is actually delayed and AMD is asking AMD to sign a new NDA to confirm the new release date.

One thing I’d like to clarify is that the August 29th event will be the “release” and not the actual “launch” which is always supposed to be in September. The It was earlier scheduled to launch on September 15 But it was recently shifted to September 27. Now we know that the main cause of this delay is related to the BIOS. As with every gen generation, the BIOS is an important part that sees various revisions for improved CPU and memory support. This time, just like the AM4 platform, there are many fixes before and after release.

So far, we have heard that there have been at least 7 AGSA 1.0.0.1 BIOS revisions from Patch A to Patch G. The latest BIOS was released this month, and things aren’t smooth sailing either.

Gigabyte has listed AGESA 1.0.0.1 Patch D (old BIOS) for its X670E AORUS Master motherboard.

Previously, motherboard vendors were expected to release AGESA BIOS v1.0.0.1 Patch D with their motherboards, but that is no longer the case as the old BIOS was not optimized enough for AMD Ryzen 7000 CPUs. The AM5 motherboard platform also supports EXPO DDR5 memory. So, there are reports that the official BIOS v1.0.0.2 will be released and we can see future revisions of the BIOS moving forward.

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

The list goes on but it’s not 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 starting sales now and users having to go through a complicated BIOS update process, AMD rescheduled the release later. Date for smoother and better first experience for users on their next generation platform.
