There are two versions of AMD’s Ryzen 7000 Desktop CPUs: one with a single CCD and the higher core count models with dual Zen 4 CCDs. AMD appears to be selling certain AM5 Ryzen 5 & Ryzen 7 processors with two CCDs, though.
If you intend to employ direct-die cooling, Der8auer has produced a video demonstrating his newest Delid Die Mate, which can be used to delid the AMD Ryzen 7000 Desktop CPUs. For this example, the overclocker employed a Thermal Grizzly Direct Die Frame, but when the Ryzen 5 7600X was delivered, an intriguing finding was made.
Der8auer noted that the AMD Ryzen 5 7600X CPU has two Zen 4 CCDs instead of one as soon as it was delid. The 7600X doesn’t require the additional CCD because it has 6 cores and 12 threads.
It’s obviously a bit interesting to see a twin Zen 4 CCD implementation on the PCB since all AMD Ryzen 7000 CPUs below the Ryzen 9 segment only use a single CCD.
Der8auer checked to see if the other Zen 4 CCD was active or not while holding the chip under a thermal probe because it had previously been delidded. On each chiplet, three tiny copper blocks were utilised to write (two Zen 4 CCDs and a single IOD). Upon booting, only the IO die and one Zen 4 CCD were visible to be active because they had begun to generate heat. The other die is not running, thus this indicates.
First and foremost, AMD might just be using faulty Ryzen 9 chips with only one functional Zen 4 CCD and marketing them as Ryzen 5 & Ryzen 7 components. This would imply that the other die is completely broken and useless. However, there is also a remote chance that this die may have been deliberately locked and that there may be a way to unlock it. It is well known that AMD artificially locks a number of features on its chips, including the Ryzen 7 5800X3D OC that will soon be bypassed.
