128GB DDR5 4800 ECC Registered Kit

This 128GB kit contains four 32GB DDR5 4800 PC5-38400 CL40 registered DIMMs. It is built for Lenovo ThinkStation P7 and PX workstations that require ECC registered memory. The modules operate at 1.1V and use a 2Rx8 organisation. They are JEDEC-standard and RoHS compliant.

Workstation and server upgrades only

This memory suits IT professionals upgrading or repairing ThinkStation P7 and PX systems. It will not work in standard desktop computers or consumer motherboards. It cannot be mixed with unbuffered or load-reduced ECC modules. Buyers needing non-ECC or unbuffered DDR5 for a regular PC should look elsewhere.

Registered ECC is the deciding spec

The modules are ECC registered RDIMMs, a requirement for the ThinkStation P7 and PX memory controllers. Standard unbuffered DIMMs will not function in these workstations. Verify that your system specifically calls for registered ECC DDR5 before ordering this kit.

Preguntas sobre este artículo

Should I choose the 4×32 GB kit or look for a different capacity?

The kit supplies 128 GB total across four 32 GB registered ECC modules, which matches the maximum supported configuration for the ThinkStation P7 and PX workstations.

What does the DDR5 4800 CL40 rating deliver in my ThinkStation P7 or PX?

Each module runs at 4800 MT/s with CAS latency 40 at 1.1 V, providing the standard JEDEC DDR5 speed grade qualified for those workstations.

How does the 288-pin registered ECC DDR5 interface limit performance?

The registered ECC RDIMM format adds one clock cycle of buffering for signal integrity, capping the memory to JEDEC-standard DDR5 4800 speeds without overclocking headroom.
