AMD’s Ryzen 7 5800X3D is reportedly not overclockable

The launch of the AMD Ryzen 7 5800X3D processor is getting closer, but this processor with its huge 96MB cache may not support overclocking, according to a user post on Bilibili. On its own, we might not read too much about it, as it may have been disabled in the BIOS or by a CPU engineering sample feature.

But, TechPowerUp adds to this news by saying that AMD is asking its motherboard partners to turn off overclocking on the Ryzen 7 5800X3D. This will disappoint some users, but it’s really not that surprising.

We can guess why this might be. Firstly, this may be due to poor heat dissipation characteristics. The presence of stacked crystals will naturally make it more difficult to cool the underlying chipset. Adding overclocking to the mixture adds heat. AMD may not be sure that the various CPU hotspots can be supported within acceptable limits when overclocking is taken into account.

The use of through-silicon vias (TSV) to connect cache memory on top of a regular Zen 3 chipset is very advanced technology. AMD can build chips to certain design parameters, but once you get beyond the base spec with higher voltages and currents, it’s likely AMD can’t guarantee the chips won’t break. He must have tested it all internally.

We already know that AMD has lower clock speeds for the 5800X3D compared to the 5800X. It will have a base clock of 3.4GHz and a base clock of 4.5GHz, which are 400MHz and 200MHz slower than the 5800X, respectively. Despite the lower clock speeds, AMD claims it can match or beat the Core i9 12900K in some games.

It will be released on April 20 for a suggested price of $449, which is the same as the Ryzen 7 5800X’s original launch price.
