AMD officially launched the Zen 4 series of Threadripper CPUs a few weeks ago, and they have recently been showing off their pro-grade CPUs by overclocking them. Over the past two days, they've let several overclockers tinker with a 96-core Threadripper model in their test lab to see how far they can push the chip. Using a custom cooling circuit, set several world records in Cinebench and GPUPI while consuming between 800 and 1.000 W in each run.
The overclocker goes by the name SAMPSON and appears as Bill Alverson on HWBot and LinkedIn. His job title is “AMD overclocking/IO performance optimization«.
AMD boasts about the overclocking they do to a 96-core AMD Ryzen Threadripper
Sampson began the experiment yesterday by operating a giant air sink on the Threadripper Pro 7995WX. This model has a configuration of 96 cores and 192 threads. It has a single-core boost clock of 5,1 GHz and a base clock of 2,5 GHz. Using a nearly two-kilogram air cooler with four 120 mm fans, it reached 4,8 GHz in the 96 cores.
The next day he used a custom liquid cooling circuit. With it, it was subjected to all versions of Cinebench and the simplest GPUPI test. In them, they achieved several world records while working with power requirements of up to 1.000 W. In Cinebench R15, they were able to squeeze the chip up to 5 GHz on all 96 cores and reach 4.966 MHz on R23, with world records in each test. Cinebench 2024 was a little more demanding, because it only allowed a frequency of 4.825 MHz, although it was also enough to break the world record. In GPUPI, the frequency was raised to 5.265 MHz, since this test is less stressful and is widely used in overclocking record races.
SAMPSON used a HeatKiller IV CPU block, a radiator ThermalTake 360 mm and an Enermax pump, according to Tom's Hardware. The equipment on which the tests were carried out included an Asus Pro WS TRX50-Safe Wi-Fi motherboard and 128 GB of DDR5-3200 memory from G.Skill.
