Some Ryzen 5 7600X CPUs have had their cores disabled by the AMD AGESA firmware

The Ryzen 5 7600X, which is considered to be one of the top central processing units (CPUs), is not generally afflicted by bad firmware. All of the samples, with the exception of the ones that used a single-CCD design, are unaffected. Even though it has six cores and twelve threads, a single CCD is all that is need for the Ryzen 5 7600X. On the other hand, some Ryzen 5 7600X CPUs include two CCDs tucked away in the chassis of the chip. Because AMD has already fused off the extra CCD, there is no way for you to suddenly obtain more cores.

Chip manufacturers such as AMD, Intel, and Nvidia repurpose dies that aren’t quite up to spec for certain models into their budget products as a standard practise with the intention of maximising the production of silicon. This helps these companies meet their manufacturing goals. Therefore, there are two CCDs in the Ryzen 5 7600X. The first iterations of the Ryzen 7 5800X and Ryzen 5 5600X both utilised the same methodology developed by AMD. It would appear that the AGESA ComboAM5PI 1.0.0.4 firmware is unable to differentiate between Ryzen 5 7600X samples that contain a single CCD and those that contain a dual CCD. It is possible that it incorrectly recognises the CCD and, as a consequence, turns off a core of the processor.

Both MSI and ASRock have removed the ability to download the firmware for their respective X670 and B650 motherboards from the product pages of their respective brands. However, the firmware is still accessible for download on some of the support pages for Gigabyte’s 600-series motherboards, despite the fact that you should avoid using it as much as possible.

If you have upgraded the firmware on your motherboard to work with Ryzen 5 7600X and experienced a significant loss in performance following the upgrade, you should roll back to the firmware that was present on the motherboard when you first installed Ryzen 5 7600X. Within the next couple of weeks, there will be a firmware upgrade that will be available that will incorporate the necessary remedy.
