256GB DDR5 4800 ECC Kit

This V-color kit provides 256GB across eight 32GB registered ECC DDR5 modules running at 4800MHz with CL40 latency. It operates at the standard 1.1V and uses Hynix ICs on a 288-pin RDIMM form factor. The memory targets servers and workstations that require registered ECC reliability for continuous operation.

Registered ECC Workstation Use

The modules suit administrators upgrading or populating DDR5-capable server and workstation motherboards that accept registered ECC DIMMs. They will not function in standard desktop PCs or consumer boards that lack registered ECC support. Builders needing unbuffered or non-ECC memory must select a different product type.

4800MHz CL40 Registered Speed

The kit runs at DDR5 4800 (PC5-38400) with timings of 40-39-39-77 at 1.10V in a 1Rx4 configuration. This JEDEC baseline speed and latency determine compatibility with the platform memory controller and qualified vendor lists. Verify that the target system supports this exact registered ECC specification before purchase.

Questions about this item

Will the 288-pin DDR5 RDIMM modules fit my server motherboard memory slots?

These are standard 288-pin DDR5 RDIMM modules that install in DDR5 RDIMM slots on server and workstation motherboards.

Do I need to configure anything in BIOS after installing the 1Rx4 ECC registered modules?

Install the modules in the correct channel order for your motherboard; the 1Rx4 registered ECC design is detected automatically at 4800 MT/s CL40 1.10 V.

How do I know when a 32 GB module in this 256 GB kit needs replacement?

The ECC function logs correctable errors; rising error counts in system logs indicate a module should be swapped before uncorrectable failures occur.
