G.Skill was able to overclock eight 32GB sticks to DDR5-8400
A new bar has been set for high-capacity memory overclocking, this time coming from the demanding world of high-end workstations. Renowned Korean overclocker ‘Phantom' has successfully pushed a colossal 256GB kit of G.Skill DDR5 Zeta R5 R-DIMM memory to DDR5-8400 with CL38-50-50 timings.
What makes this record particularly noteworthy is that it was achieved across all eight memory channels of a workstation platform and was proven stable under the MemtestPro stress test. The new record saw a 256GB kit, comprised of eight 32GB modules of G.Skill's DDR5 Registered DIMM memory, pushed to a blistering DDR5-8400. What makes this even more impressive are the tight timings achieved at that speed: CL38-50-50. Of course, a feat like this requires some compelling hardware. The record was set on a test bench featuring the new 64-core AMD Ryzen Threadripper Pro 9985WX processor and an Asus Pro WS WRX90E-Sage SE motherboard.




With this memory kit overclocked, Phantom was able to set six new world records during the Asus Threadripper Pro launch overclocking event. Those include new record highs for Y-Cruncher 1B, 2.5B, and 5B (all 64xCPU) using a Ryzen Threadripper Pro 9985WX, and Cinebench R20 and R23 32xCPU and Y-Cruncher Pi-5B 32xCPU records with the Ryzen Threadripper Pro 9975WX. The motherboard was the same Asus Pro WS WRX90E-Sage SE across all entries.
While most users won't be pushing their workstation memory to these extremes, this achievement could be interesting for professionals. Workloads sensitive to memory bandwidth and latency, such as large-scale 3D rendering, scientific simulations, or AI training, can see significant reductions in processing time from an overclock such as this.
KitGuru says: Even though DDR5-8400 is far from setting a speed record in the DDR5 realm, doing it across eight modules running at CL38-50-50 is mighty impressive.
