According to reports, AMD Ryzen 7 5800X3D does not enable overclocking (updated)

Overclocking is not currently supported on the upcoming Ryzen 7 5800X3D. What's critical to notice is that the original posting makes no indication that there is a permanent lack of this capability, or simply the present level of firmware support.

The original communication included a photograph of the processor with the OPN and QR codes obscured. AMD's first consumer CPU, the 5800X3D, features 96MB of 3D V-Cache layered on a single 8-core chiplet. Yesterday, we revealed that this SKU will be available on April 20 for $449 USD, the same price as the Ryzen 7 5800X's initial MSRP. The latter is likely to see a price reduction upon the release of the new X3D component.

AMD's Ryzen 7 5800X3D processor has a base frequency of 3.4 GHz and a boost clock of 4.5 GHz, which is 400 MHz and 200 MHz slower than the 5800X. However, AMD believes that the CPU will deliver up to 20% greater gaming performance in select titles than the Core i9-12900K because to the massive L3 cache.

Update: AMD's Robert Hallock confirms that the Ryzen 7 5800X3D lacks manual overclocking.

AMD's Ryzen 7 5800X3D lacks manual CPU overclocking functionality, and AMD has instructed its motherboard partners to remove these options from the UEFI. The CPUs are reported to be hard-locked, thus there is no workaround for modifying the CPU multiplier or voltage. Here's why; the 3D V-Cache has Voltage restricted at 1.3 to 1.35 Volts, which means that the typical boost Voltage of individual Ryzen CPU cores, which may reach 1.45 to 1.5 Volts, would be too high for the 3D V-Cache to manage. As a result, AMD imposed the limitations on this CPU.

The lower Voltage boost also helps to explain why the Ryzen 7 5800X3D has lower boost clocks, since larger Voltages may be required to reach higher frequencies. However, Robert Hallock made it clear that overclocking is a priority for AMD, and the Ryzen 7 5800X3D is an exception in terms of these constraints.
