1TB DDR4-3200 8Rx4 Registered ECC Kit

This 1TB kit contains four 256GB DDR4-3200 (PC4-25600) Registered ECC RDIMMs rated CL22 at 1.20V. The modules use a 288-pin form factor and an 8Rx4 organisation built with major-brand Samsung, Micron or Hynix DRAM. They are qualified for Supermicro X12DPL-NT6 and X12DPL-i6 motherboards that require registered memory.

Suited for servers needing maximum registered

This kit suits administrators populating every slot of a compatible Supermicro X12DPL board with the highest-density registered ECC modules the platform accepts. It is not for systems that only accept unbuffered UDIMMs, SODIMM form factors, lower-density ranks, or speeds other than DDR4-3200.

8Rx4 rank organisation decides compatibility

The 8Rx4 rank structure is the single specification the memory controller checks before recognising each 256GB module at full capacity. If the motherboard's qualified-vendor list does not explicitly approve 8Rx4 Registered DIMMs, the system will not boot or will see reduced capacity.

Questions about this item

What motherboard and CPU combination must I already have for this 1TB DDR4-3200 8Rx4 RDIMM kit to be recognised at full capacity?

This kit is verified for Supermicro X12DPL-NT6 and X12DPL-i6 motherboards running DDR4 3200 PC4-25600; the board must support 288-pin registered ECC modules and 8Rx4 population rules.

If I keep older DDR4 RDIMMs in the same server, will this 8Rx4 1.2 V CL22 kit run alongside them without down-clocking?

Mixing ranks or speeds forces the memory controller to run all slots at the lowest common speed and timing; for stable full-speed operation populate every channel with identical 8Rx4 modules.

After installation, how can I confirm the server sees all 1 TB at DDR4 3200 CL22 with ECC active?

Check the BIOS memory information screen or run dmidecode — it should report four 256 GB DDR4 3200 registered ECC DIMMs at 1.2 V, CAS 22, total 1 TB.
