AMD Ryzen 7000X3D: No OC but support for PBO 2 and the Curve Optimizer

Like the AMD Ryzen 7 5800X3D (test), the three upcoming Ryzen 7000X3D, the Ryzen 9 7950X3D, Ryzen 9 7900X3D and Ryzen 7 7800X3D, will not require manual overclocking of the Zen 4 Processor cores support, but unlike the direct predecessor, the OC features Precision Boost 2 and the Curve Optimizer.

No classic overclocking

After an error crept in for a short time on the product page of the AMD Ryzen 9 7950X3D and the processor was reported as “Unlocked for Overclocking”, the manufacturer quickly retracted this notice, like the previously announced release for February 14th, and the Specifications corrected accordingly. The entry has disappeared from the product page. The support for manual OC would have been quite a surprise.

Support for PBO and Curve Optimizer

The Ryzen 9 7950X3D, 7900X3D and Ryzen 7 7800X3D should instead support the following Auto-OC functions, as HardwareLuxx has learned.

  • AMD Precision Boost Overdrive ✓
  • AMD Precision Boost 2 ✓
  • AMD Curve Optimizer ✓
  • AMD EXPO Memory ✓

Precision Boost 2 and the Curve Optimizer were not officially supported by the direct predecessor, the Ryzen 7 5800X3D, and would at least give users a little leeway for overclocking and undervolting with the new Ryzen 7000X3D.

Ryzen 7000X3D Series processors are unlocked for memory and infinity fabric overclocking, just like Ryzen 5800X3D. New to the 7000X3D, we have also added PBO and Curve Optimizer capabilities.

Besides RAM OC, which is both manual and via the ready-made EXPO Profile can be performed, the Infinity Fabric can still be overclocked via the BCLK. Overall, the X3D CPUs with stacked L3 cache offer very little scope for manual optimization.
