Single green DDR4 LRDIMM module with gold contacts and black chips

Axiom

Axiom T9V42AA-AX server RAM 64 GB DDR4 2400 MHz CL17 LRDIMM 288-pin ECC 1.2 V

SKU CH-GMD1-67PGW MPN T9V42AA-AX

64 GB DDR4 LRDIMM module with ECC, CL17 latency and 1.2 V operation for compatible HP Z840 workstations

  • 64 GB capacity supports large virtualised workloads
  • 2400 MHz DDR4 speed delivers high data throughput
  • CL17 latency ensures responsive memory access
  • ECC protection detects and corrects data errors
  • Load-reduced 288-pin DIMM lowers electrical load on server bus

64 GB DDR4 LRDIMM for HP Z840 Workstations

This 64 GB DDR4 load-reduced DIMM operates at 2400 MHz with CL17 latency and 1.2 V power draw. It is built for HP Compaq Workstation Z840 systems that require ECC registered memory. The 288-pin module follows the PC4-19200 standard for server-grade reliability.

288-pin LRDIMM form factor with RoHS compliance

The load-reduced design lowers electrical load on the memory bus, allowing higher capacity per channel in supported workstations. A 288-pin DIMM layout fits standard DDR4 server slots without adapters. RoHS certification confirms the assembly meets restricted-substance requirements for environmentally friendly deployment.

DDR4-2400 bandwidth ceiling

The DDR4-2400 interface caps throughput at the PC4-19200 rate, so workloads needing higher memory bandwidth will not benefit from faster clocks on this module. ECC error correction adds latency overhead compared to non-ECC alternatives. Builders needing more than 64 GB per slot must look to higher-density LRDIMM or 3DS parts not covered here.

Questions about this item

What bandwidth does the DDR4-2400 standard provide for this module?

The DDR4-2400 standard is rated at PC4-19200, which specifies the peak transfer rate for this memory module.

What slot type and pin count does this 288-pin LRDIMM require on the motherboard?

This module uses a 288-pin DIMM form factor and requires a standard DDR4 DIMM slot that supports load-reduced memory.

How is the module installed and what alignment step is often missed?

Align the notch on the module's gold edge connector with the key in the DDR4 DIMM slot, then press down firmly until the retaining clips on both ends click into place to secure the module.
