System-Specific 64GB DDR4 Kit

This 64GB kit contains eight 8GB DDR4 ECC unbuffered UDIMM modules rated at 3200 MT/s with CL22 latency. It is built for the ASUS Pro WS WRX80E-SAGE SE WiFi motherboard and similar workstation platforms that require registered-error-correction memory in a 288-pin form factor.

DDR4 3200 Interface Constraints

The DDR4 3200 standard caps transfer rates at 3200 MT/s and operates at 1.2V, so bandwidth cannot exceed the PC4-25600 ceiling regardless of how many modules are populated. ECC overhead and the unbuffered topology add latency that cannot be removed by firmware tuning.

1Rx8 Rank Determines Compatibility

Each module uses a single-rank 1Rx8 organisation, which fixes the electrical load per slot and dictates whether the memory controller can address the full 64GB without exceeding rank limits.

Questions about this item

Should I pick the 64GB kit or a smaller 8GB module?

The kit supplies 64GB total across eight 8GB modules; choose it when the board has eight slots and the workload needs that capacity.

What does the 3200 speed deliver on an ASUS Pro WS WRX80E-SAGE SE WiFi board?

The modules run at DDR4 3200 (PC4-25600) with CL22 latency at 1.20V, giving the rated bandwidth the motherboard supports.

Does the 288-pin ECC UDIMM interface limit anything on this platform?

The 288-pin unbuffered ECC UDIMM fits the board's DDR4 slots directly; the memory controller caps the kit at 3200 MT/s.
