Capacity 256GB (2 x 128GB)

  • ECC registered design protects data integrity in critical workloads
  • 256 GB kit (2 × 128 GB modules) expands workstation capacity
  • DDR5 4800 speed delivers high bandwidth for demanding applications
  • JEDEC-standard 1.1 V operation ensures compatibility and efficiency

Compatible workstation upgrade

This 256GB DDR5 memory kit is built for Lenovo ThinkStation P7 and PX workstations. It delivers registered ECC stability for professional workloads that demand data integrity and continuous uptime.

Suited for ECC registered slots only

The modules require DDR5 registered ECC slots and will not operate in standard desktop motherboards or systems that use unbuffered or load-reduced memory. Buyers needing consumer memory or mixed-rank configurations must choose a different product.

4800 MT/s registered ECC specification

The kit runs at DDR5 4800 (PC5-38400) with CL40 latency at 1.1V using 4Rx4 registered DIMMs. This speed and registration type determine whether the workstation will accept the upgrade.

Preguntas sobre este artículo

Should I pick the 256 GB kit or look for a different capacity?

This kit provides exactly 256 GB as two 128 GB modules, the only capacity offered for this ThinkStation P7 and PX upgrade.

What does the 4800 MHz rating mean once the modules are installed in my workstation?

The modules run at DDR5 4800 with CL40 latency and 1.1 V, delivering the JEDEC-standard data rate supported by the ThinkStation P7 and PX memory controller.

Does the 288-pin ECC Registered RDIMM interface limit the speed I can actually use?

The 288-pin RDIMM form factor carries the DDR5 4800 signal; the registered buffer and ECC function operate at that rated speed without further reduction.
