1TB DDR4-3200 ECC RDIMM kit

This kit supplies 1TB of DDR4-3200 registered ECC memory across sixteen 64GB modules. It runs at 1.2V with a CAS latency of 22 and uses a 4Rx4 organisation on 288-pin DIMMs. The chips come from major OEM suppliers such as Samsung, Micron or Hynix. It is built for servers that require registered DDR4-3200 memory.

Suited for multi-socket servers needing maximum

This memory fits servers that accept 4Rx4 registered DDR4-3200 DIMMs and can populate sixteen slots. It is not for desktop PCs or workstations that only support unbuffered memory. It is also not for platforms limited to lower ranks or fewer memory channels. Buyers needing unbuffered ECC or consumer DDR4 should look elsewhere.

Sixteen matched modules simplify large-scale

The kit delivers sixteen pre-matched 64GB RDIMMs in a single package. This removes the need to source and validate individual sticks for a full 1TB configuration. Consistent 4Rx4 ranking across all modules helps maintain stability in dense memory subsystems. No additional software or accessories are included beyond the memory itself.

Questions about this item

Does my server motherboard need 288-pin DDR4 slots that support ECC and registered 4Rx4 modules to use this 16-module kit?

Yes, the kit consists of 16 registered ECC RDIMMs with a 4Rx4 organisation, so the platform must provide 288-pin DDR4 slots that accept registered memory and can address four ranks per module.

Can I keep my existing DDR4 3200 registered ECC DIMMs and add this 1 TB kit without changing voltage or speed settings?

The modules run at 1.2 V and DDR4 3200 with CAS 22; if the installed DIMMs share those timings and are also registered ECC, the system will typically train all sticks to the common JEDEC profile.

After installation, how do I confirm the full 1 TB is recognised and ECC is active?

Check the BIOS memory summary or the OS memory report — both should show 1 TB total capacity and indicate ECC enabled for the 16 modules.
