Twelve green DDR5 RDIMM modules in a row

NEMIX RAM

NEMIX RAM 1.5TB (12 x 128GB) DDR5 4800MHz Server RAM

SKU CH-H732-Y0JQE

A 1.5 TB DDR5 registered ECC kit of twelve 128 GB modules running at 4800 MHz with CL40 latency at 1.1 V

  • Low 1.1 V operating voltage reduces power draw per module

Server DDR5 ECC RDIMM kit

This NEMIX RAM kit provides 1.5 TB of registered DDR5 memory across twelve 128 GB modules. It is built for enterprise servers that require error-correcting code and registered buffering for data integrity. The kit is not suitable for standard desktop PCs or consumer motherboards that lack RDIMM support.

DDR5 4800 registered limits

The modules operate at DDR5 4800 (PC5-38400) with a CAS latency of 40 and a voltage of 1.1 V. Registered DIMMs add a clock cycle for buffering, so the platform must support RDIMM topology and the full 12-slot population. Systems limited to UDIMM or fewer slots cannot use this configuration.

12-module installation notes

Installing all twelve 288-pin modules fills every available slot on many dual-socket boards, requiring careful CPU and memory-channel population order. Mixing ranks or speeds will prevent boot. The 2Rx4 organisation demands a compatible memory controller; consumer chipsets will not recognise the modules.

Questions about this item

Should I buy the 12-module 1.5TB kit or look for a different capacity?

The kit provides 1.5TB total capacity across 12 modules of 128GB each, designed for servers that need maximum registered ECC memory in a single DDR5 4800MHz configuration.

What does the DDR5 4800MHz PC5-38400 rating mean for actual server performance?

It delivers a peak transfer rate of 38400 MB/s per module at 4800 MT/s with CAS latency 40 and 1.1V operation, optimised for registered ECC workloads in compatible server platforms.

Is the 288-pin RDIMM interface compatible with standard DDR5 server motherboards?

Yes, the 288-pin registered DIMM form factor with 2Rx4 organisation and ECC is the standard DDR5 server memory interface for platforms supporting PC5-38400 registered memory.
