It's a shame, but at least the reason they give for that limitation makes sense: https://www.techpowerup.com/293001/amds-robert-hallock-confirms-lack-of-manual-cpu-overclocking-for-ryzen-7-5800x3d It turns out that the 3D V-Cache is Voltage limited to a maximum of 1.3 to 1.35 Volts, which means that the regular boost Voltage of individual Ryzen CPU cores, which can hit 1.45 to 1.5 Volts, would be too high for the 3D V-Cache to handle. As such, AMD implemented the restrictions for this CPU. However, the Infinity Fabric and memory bus can still be manually overclocked. The lower Voltage boost also helps explain why the Ryzen 7 5800X3D has lower boost clocks, as it's possible that the higher Voltages are needed to hit the higher frequencies. |
It will be interesting to see exactly how much of a performance improvement the cache brings to gaming cause a 5800X is officially $100 cheaper and typically be had for even less than that. And Intel gives you more performance in games as well so for 5800X3D to be worth it, the cache really needs to carry a lot.
