AMD Ryzen X399 Motherboards Revisited – The ASRock X399M Taichi and ASUS X399-E ROG STRIX Review

Test Setup

For this review, I had access to the Ryzen Threadripper 1920X and the Ryzen Threadripper 1900X processors. AMD did not provide us with any equipment or processors for this review.

The motherboards were sent by ASRock and ASUS while one of the AMD Ryzen Threadripper CPU was bought of my own expense. Our review is entirely based purely on facts and precision. The full test setup configuration can be seen in the provided list below:

AMD Ryzen Threadripper 2018 Test Bench:

I would like to thank G.Skill for providing the Trident Z RGB memory, ASUS for providing the GTX 1080 TI STRIX OC and Noctua for providing their high-end NH-U14S (TR4 SP3 Socket).

For overclocking, the maximum clock speeds I was able to achieve on the ASRock X399M Taichi was 4.15 GHz across all cores while the ASUS ROG STRIX X399-E Gaming gave an extra 100 MHz boost to 4.2 GHz across all 12 cores. Similarly, the X399M Taichi and ROG STRIX were able to achieve 4.25 GHz on the Ryzen Threadripper 1900X which was achieved with 1.43V, just barely below the AMD's own recommended limit of 1.45V. The results are provided in the next section.
