All-core overclocks of 4.0GHz, or very close to it, were possible when feeding 1.4V to the chips. We managed roughly the same frequencies that we tend to see on Ryzen CPUs with lower core counts. Our overclocking results with the Ryzen Threadripper processors were generally positive. In short, our final Ryzen Threadripper 1920X overclocking settings were: The 360mm AIO kept the chip just below the throttling point and power draw was reduced by roughly 100W compared to the 16-core. Despite the reduction in core count, temperatures were still as high as they were on the 1950X while running the AIDA64 stress test. This was using the same 1.3875V core voltage in the UEFI (1.395V loaded in the OS).

We managed to maintain full stability at 4.0GHz with the 12-core chip, however.

These settings kept temperatures (just about) in check at below 85☌ using the 360mm AIO cooler. We finally settled on 3.95GHz across all 16 cores with a UEFI-set voltage of 1.3875V and Level 1 LLC (which resulted in 1.395V under load). We pushed a little further and managed to hit 4.0GHz with Cinebench and Handbrake stability but AIDA64 would not pass its stability test.
We were able to hit 3.9GHz very easily with minimal adjustment to the system – we simply applied 1.4V VCore in the UEFI and opted for the Level 1 LLC setting. Overclocking with the Ryzen Threadripper 1950X is very similar to the procedure with other Ryzen chips. We also point a 100mm Antec Spot Cool at the VRM heatsink to provide additional direct airflow for cooling.
We chose the ASUS motherboard due to its strong power delivery system, dual 8-pin power connectors, and active VRM cooling. The partnering hardware of choice is the ASUS ROG Zenith Extreme X399 motherboard, 32GB of G.SKILL TridentZ 3200MHz CL14 DDR4, and a Seasonic 760W Platinum PSU. We do not use Prime95 as we have found it to be overly demanding as a stress test application with the more recent AVX-capable versions. Stability is confirmed by running multiple Cinebench tests, Handbrake video conversion, and AIDA64 CPU, FPU, and Cache stress test for at least 1 hour. We also used sensible voltages that lead to manageable thermal results. Our usual Corsair H110i GT is not compatible with the new TR4 socket. As such, we test with sensible cooling hardware in the Thermaltake Floe Riing 360, which is a 3x120mm Asetek-based AIO liquid cooler. We encourage to check and leave feedback on this forum thread.Our objective with CPU overclocking is to hit frequencies that we think will be achievable for daily use by the platform’s buyers. Note: This is an unofficial modded version of Cinebench 15 (it has a few some changed configuration files), this revision of software is not supported or distributed by Maxon. It's a simple trick, the Cinebench render resolution has been increased by fourfold, giving the benchmark a much longer and larger workload, this results into a more reliable score with the 64-threaded beasts we have available these days. With that idea in mind Guru3D's HWGeek started modding Cinebench. That's not entirely realistic as processors clock down after a number of seconds of full stress. That means that any Turbo can run 100% all the time as the benchmark finishes (too) fast. The 16-core and even 32-core processors these days can finish up the benchmark in merely seconds. However, Maxon never updated it to cope with many-core processors.
