Capacity and role

This 8 GB DDR4 module is built for servers and workstations that require ECC unbuffered memory. It replaces the HP 934797-001 part and fits 288-pin DIMM slots running at 2400 MHz.

Sustained operation

ECC circuitry corrects single-bit errors during continuous workloads, keeping data integrity stable over long periods. The CL17 latency and 1.20 V voltage maintain consistent timing without the higher power draw of registered alternatives.

DDR4 interface limits

The DDR4 2400 standard caps transfer rates at PC4-19200, so bandwidth cannot exceed that ceiling. Unbuffered design also restricts the maximum module count per channel compared with registered DIMMs.

Questions about this item

How much heat and power does this 1.2V DDR4 2400 ECC UDIMM draw when running continuously in a server?

At 1.20 V the module operates at standard DDR4 voltage, keeping power draw and heat low enough for 24/7 server workloads without extra cooling.

What must my motherboard provide for this 288-pin DDR4 2400 ECC UDIMM to function?

A DDR4 DIMM slot that accepts unbuffered ECC memory at 2400 MHz and supplies 1.20 V.

Can I mix this CL17 1Rx8 module with slower DDR4 sticks already installed?

The system will run all modules at the speed and timings of the slowest stick, so this CL17 2400 MHz module will downclock to match older DDR4.
