Server-grade memory kit

This 1TB kit contains eight 128GB DDR4 2933 ECC load-reduced DIMMs built for the HP ProLiant XL270d Gen10. The modules run at 1.2V with CL21 latency and an 8Rx4 organisation. They are not compatible with standard desktop computers and cannot be mixed with unbuffered or registered ECC memory.

Sustained workload behaviour

Load-reduced architecture reduces electrical load on the memory controller, helping maintain signal integrity when all channels are fully populated. Backward compatibility with 2133, 2400 and 2666MHz systems allows the kit to run at the highest speed the platform supports. ECC circuitry corrects single-bit errors during continuous operation.

Thermals, noise and power

The modules operate at 1.2V without heat spreaders, relying on chassis airflow for cooling. Power draw scales with the number of installed DIMMs and the configured memory speed. No active cooling components are present, so acoustic output depends entirely on the server fan profile.

Soalan tentang produk ini

How much power does the 1.2V LRDIMM kit draw when the server runs continuously?

Each module operates at 1.2V DDR4 voltage; total system draw depends on the HP ProLiant XL270d Gen10 memory controller and workload, not on the kit alone.

What must the HP ProLiant XL270d Gen10 already have to accept this 8×128GB ECC LRDIMM kit?

The server needs free 288-pin DDR4 slots that support ECC Load Reduced memory and a BIOS that recognises 8Rx4 128GB modules; it cannot mix with unbuffered or registered DIMMs.

Will these 2933MHz modules run stably alongside existing 2400MHz DIMMs left in the XL270d Gen10?

The kit is backward compatible with 2133MHz, 2400MHz and 2666MHz speeds, so the system will clock all populated slots to the lowest common speed.
