Server Memory Kit

This 48 GB kit contains six 8 GB DDR4 ECC RDIMM modules rated at 2933 MT/s with CL21 latency. It is built for servers and workstations that require registered, error-correcting memory for stable operation under continuous workloads.

Thermals and Power

Each module runs at 1.20 V without a heat spreader, relying on server chassis airflow for cooling. Registered buffering reduces electrical load on the memory controller, helping to keep system power draw predictable during sustained use.

Compatibility and Use

The 288-pin RDIMM form factor fits only motherboards that support registered ECC DDR4; it will not work in consumer desktop boards that require unbuffered DIMMs. Buyers who need non-ECC memory or a different capacity per module should select another kit.

Questions about this item

How do I install these 288-pin DDR4 RDIMM modules and what step is often missed?

Power down the server, open the chassis, align each module's notch with the slot key, press firmly until both retention clips click, then verify in BIOS that all 48GB are recognised at 2933 MT/s.

What maintenance or replacement will this 1Rx4 ECC registered kit need over time?

No scheduled maintenance is required; ECC corrects single-bit errors on the fly, and a module is only replaced if the system logs uncorrectable errors or a DIMM fails POST.

What limit appears first when the 1.20 V registered DIMMs run sustained workloads?

The DDR4 2933 CL21 timing and 1Rx4 organisation set the bandwidth ceiling; sustained loads will saturate throughput before voltage or thermal limits are reached.
