Capacity and fit

This 4GB DDR4 module runs at 2400MHz with CL17 latency and 1.20V operation. It is built as an ECC unbuffered UDIMM in a 1Rx8 configuration for server and workstation systems. The part is a compatible replacement for HP 934796-001 and uses a 288-pin DIMM form factor.

Sustained workload behaviour

ECC circuitry corrects single-bit errors on the fly, keeping data integrity intact during long compute runs or virtualization tasks. Unbuffered signalling reduces command overhead, so the module maintains steady throughput without the latency penalty of registered designs. Major-brand chips and factory testing aim to deliver consistent reliability across extended duty cycles.

Installation notes

The stick installs in any standard DDR4 UDIMM slot keyed for 288 pins; alignment notches prevent backward insertion. Verify the platform supports ECC unbuffered memory and the 1Rx8 organisation before fitting, as some consumer boards disable ECC or require registered modules. No special tools or firmware updates are needed beyond the usual BIOS memory training.

Questions about this item

How much heat and power does this 1.2V DDR4 module add when running all day?

At 1.20V standard DDR4 voltage the module draws minimal power and produces very little extra heat inside a server chassis.

What must my motherboard provide for this 288-pin UDIMM to work?

A DDR4 DIMM slot that accepts 288-pin unbuffered ECC memory and supports 2400 MHz operation.

Will this 1Rx8 ECC stick run alongside older non-ECC DDR4 DIMMs I already own?

Mixing ECC and non-ECC modules is not supported; the system will disable ECC or fail to boot.
