G.SKILL F5-6800R3445G32GE8-G5N 256GB (8 x 32GB) DDR5 6800 ECC Registered server RAM

G5 Neo Series DDR5 6800 ECC Registered Kit

This octa-channel kit delivers 256GB across eight 32GB registered DDR5 modules rated at 6800 MT/s with CL34 timings. It targets AMD Ryzen Threadripper 7000WX series workstations that require registered ECC memory for data integrity. The kit is validated for AMD WRX90 chipset motherboards with eight-channel support and uses the AMD EXPO profile for one-click overclock configuration.

256GB capacity for multi-threaded workloads

The 256GB total provides ample headroom for large-scale rendering, simulation datasets and virtualisation clusters that exceed typical consumer limits. Eight registered modules operate at 1.40V with 34-45-45-108 timings, balancing bandwidth and stability under sustained load. Workloads that demand more than eight channels or higher per-module density will exceed this kit's physical and electrical design.

DDR5 RDIMM registered interface constraints

The 288-pin RDIMM form factor requires a motherboard with registered DIMM slots and an AMD WRX90 chipset supporting eight-channel operation; consumer or unbuffered platforms cannot accept these modules. On-die ECC and side-band ECC protect data paths, but the registered buffer adds one cycle of latency versus unbuffered DDR5. AMD EXPO profiles simplify tuning, yet final stability depends on the CPU memory controller and motherboard QVL validation.
