In an impressive showcase of technological prowess, achieving a 6400 MT/s (mega-transfers per second) with a dual-channel configuration is a notable milestone, especially when it involves four DDR5 RAM modules on an AM5 motherboard. Kingston has surpassed expectations with its 192 GB RAM kit, hitting this incredible speed while paired with the AMD Ryzen 7 9800X3D processor.
This achievement marks a significant victory for the AM5 platform, which traditionally faced challenges when attempting high memory frequencies. Unlike cutting-edge Intel LGA 1851 motherboards that regularly break the 12000 MT/s speed mark, AMD platforms have not typically focused on such extreme memory overclocking, making this accomplishment particularly noteworthy.
While the leap to 12000 MT/s remains a daunting challenge, even attaining 1000 MT/s+ speeds can be difficult when using multiple RAM modules. This makes the success of the 192 GB DDR5 RAM kit even more impressive. The feat involves maximizing the memory capacity supported by the AMD Ryzen 7 9800X3D, a difficult task achieved by an overclocking enthusiast.
The configuration in question utilized the MSI MEG X870E GODLIKE motherboard. The enthusiast installed four 48 GB UDIMM DDR5 RAM sticks from Kingston, thus employing a 2DPC 2R configuration—meaning two DIMMs per channel, dual rank. This setup typically achieves 3600 MT/s, according to AMD’s guidelines, and with overclocking, the MEG X870E GODLIKE can reach up to 4800 MT/s.
Breaking past these expectations, the overclocking achievement reached an astonishing 6400 MT/s speed. Managing dual-rank memory with DIMMs sharing channels can be challenging due to increased electrical load and signal integrity issues like reflections and interference. To counter these challenges, the overclocker had to meticulously adjust latency timings and other memory settings from the BIOS.
The CPU-Z window revealed CL timings of 48-48-48-103, ensuring satisfactory performance. To stabilize this setup, the voltage was increased from 1.10V to 1.40V. According to RunMemtest Pro, the RAM kit exhibited a low error rate, confirming the stability of the setup for handling demanding workloads.
It’s important to note, however, that not every X870/X870E motherboard and RAM kit can replicate these results. Additionally, while 192 GB of RAM running at 6400 MT/s might not be necessary for most mainstream PC users, this achievement highlights the AM5 platform’s significant advancements in memory support. This accomplishment is a testament to the platform’s growing capabilities and potential.
