Ryzen Threadripper 5990X engineering sample overclocked to 4.82 GHz and set several benchmark records Ryzen Threadripper 5990X engineering sample overclocked to 4.82 GHz and set several benchmark records

Enthusiast SkatterBencher overclocked an engineering sample of the unreleased 64-core Ryzen Threadripper 5990X processor to 4825 MHz. The author talks in some detail in his videos about each overclocking step. In the last such video, he overclocked a sample of an AMD HEDT processor that never appeared on the market – AMD decided to release only professional Ryzen Threadripper Pro and abandon the conventionally consumer Ryzen Threadripper.

The key difference between the engineered Ryzen Threadripper 5990X and the Ryzen Threadripper Pro 5990WX that hit the market is that the former can work with motherboards based on the AMD TRX40 chipset. In turn, the second is designed for AMD WRX80 boards. In his experiment, the enthusiast used the ASUS ROG Zenith II Extreme motherboard on the TRX40. It is curious that the overclocking of the chip was carried out without the use of extreme cooling in the form of liquid nitrogen. The overclocker used a custom liquid cooling system.

SkatterBencher received an engineering chip sample with OPN number 100-000000443-40_Y. This modification of the processor has already flashed in the Sharkstooth-CGL test systems. At stock settings, this chip runs at up to 4.4GHz on all cores, which is 100MHz slower than the Ryzen Threadripper Pro 5990WX. In his video, the enthusiast showed examples of all possible methods for increasing the frequency, including automatic overclocking using the built-in overclocking functions AMD Precision Boost Overdrive and Curve Optimizer. However, it was manual overclocking that made it possible to achieve the best result.

Depending on the test, the processor was able to work stably with different maximum frequencies. AI Benchmark managed to get the chip to work at up to 4.375 GHz on the fastest of the eight core crystals (CCD). Fortunately, it is possible to manually adjust the frequency of each individual CCD. In Cinebench R23, the frequency of 4.525 GHz was conquered, but in 3DMark, the enthusiast achieved a record frequency of 4.825 GHz from the processor at a voltage of 1.42 V. The rest of the crystals were forced to work at frequencies up to 4.6–4.7 GHz. At maximum frequencies, the peak power consumption of the processor increased to 691 watts.

Overclocking was enough to get more than 100 thousand points in the Cinebench R23 multi-threaded performance test, which is 58% higher than the result at the standard settings of the Ryzen Threadripper 5990X.

With the highest frequency, the processor was able to show a result of 32,950 points in the 3DMark test. For comparison, the previous record in this test, at just 27,202 points, was held by the AMD Ryzen Threadripper 3990X overclocked to 4.5GHz.

AMD has announced that the Ryzen Threadripper Pro 5000WX processors also support manual overclocking. In particular, the manufacturer indicated that some models of AMD WRX80 motherboards from partners will support memory and CPU overclocking, which may appeal to those owners of workstations based on these processors who want to get the maximum performance from them.
