Server-grade capacity

This 384 GB kit contains eight 48 GB DDR5 modules built for registered ECC server memory slots. It targets administrators upgrading the ASRock Rack W890D8-2L2T platform or similar workstations that require registered DIMMs with error correction. The 2Rx8 organisation and CL52 timing suit multi-channel configurations where stability outweighs low latency.

Thermals and power

Each module runs at 1.1 V without a heat spreader, relying on chassis airflow for cooling. The low voltage helps keep power draw modest in fully populated systems, while the registered buffer reduces electrical load on the memory controller. In typical server workloads the kit operates within standard DDR5 thermal limits without active cooling on the modules themselves.

Build and connectivity

The 288-pin RDIMM form factor fits only registered DDR5 slots; it cannot be used in unbuffered desktop or laptop sockets. Eight modules fill all channels on compatible dual-socket boards, so expansion beyond this kit requires replacing modules rather than adding them. Buyers needing non-ECC memory or consumer form factors should look elsewhere.

この商品に関する質問

How do I install the 288-pin DDR5 RDIMM modules in the ASRock Rack W890D8-2L2T motherboard?

Power down the server, open the chassis, align each module's notch with the slot key, press firmly until the retention clips click, then populate all eight slots following the board's channel order in the manual.

What maintenance will the 2Rx8 registered ECC modules require over time?

No scheduled maintenance is needed; keep airways clean so the 1.10V modules stay cool, and run the platform's built-in memory diagnostics if the OS logs corrected ECC events.

At what point does the CL52 latency become the bottleneck during sustained workloads?

CL52 sets the minimum command-to-data delay; under continuous heavy traffic the fixed 52-cycle wait limits throughput before bandwidth or thermal limits are reached.
