This kit provides 256 GB of DDR5 4800 memory in four 64 GB registered ECC modules. It is built for Lenovo ThinkStation P7 and PX workstations that require registered DIMMs. The modules operate at 1.1 V with CL40 latency and a 2Rx4 rank configuration.

Suited for registered ECC workstations not

This memory fits workstations and servers that demand registered ECC DDR5. It will not work in standard desktop computers that use unbuffered non-ECC modules. It also cannot be mixed with unbuffered or load-reduced ECC memory. Buyers needing unbuffered consumer RAM should choose a different product.

288-pin registered ECC DDR5 at 4800 MT/s

The decisive specification is the 288-pin registered ECC DDR5 4800 form factor. Only systems that accept registered ECC RDIMMs at this speed and pin count can use this kit. Verify the motherboard memory list before purchase.

Soalan tentang produk ini

Does this 256GB kit of four 64GB DDR5 4800 CL40 RDIMMs require a Lenovo ThinkStation P7 or PX workstation to operate?

Yes, the kit is validated for Lenovo ThinkStation P7 and PX systems that accept DDR5 4800 ECC registered RDIMMs; other platforms are not supported.

Can I mix these registered ECC DDR5 modules with any unbuffered or load-reduced memory already installed in the ThinkStation?

No, the modules are registered ECC and must not be mixed with unbuffered or load-reduced memory; all slots should use matching registered ECC RDIMMs.

After installation, how can I confirm the four 64GB sticks are running at DDR5 4800 CL40 with ECC active?

Check the system BIOS or UEFI memory information screen; it should report 256GB total, DDR5 4800 speed, CL40 timings, 1.1V voltage, and ECC registered status.
