  • 512 GB total capacity from four 128 GB modules for dense server workloads
  • DDR4 3200 speed with CL22 latency delivers rated throughput for Supermicro X12QCH+
  • Registered ECC design corrects single-bit errors and buffers signals for full-slot stability
  • 2 V operation at 2Rx4 rank matches the motherboard's memory-controller requirements exactly
  • 288-pin RDIMM form factor fits the board's DIMM slots without adapter or mismatch

Capacity and fit

This kit delivers 512 GB across four 128 GB DDR4 3200 registered ECC RDIMMs. It is built for the Supermicro X12QCH+ motherboard and matches the board's required 288-pin RDIMM form factor, 2Rx4 rank structure, 1.2 V operation and CL22 timing.

Upgrade path

The modules replace any lower-capacity or slower DDR4 RDIMMs currently installed in compatible Supermicro servers. The jump is worthwhile when workloads demand maximum supported memory per channel and registered ECC stability for continuous operation.

Who should buy

This suits administrators expanding memory on validated Supermicro platforms that require registered ECC RDIMMs at this exact speed and rank. Builders needing unbuffered UDIMMs, SODIMMs, non-ECC modules or different voltages should look elsewhere.

Questions about this item

Will these 288-pin RDIMMs fit the DIMM slots on my Supermicro X12QCH+ motherboard?

Yes, the kit uses the 288-pin DDR4 RDIMM form factor required by the X12QCH+ board, so each module seats directly in the server's standard DIMM slots.

What is the correct population order when installing all four 128GB modules on the X12QCH+?

Consult the motherboard manual for the approved DIMM population sequence; the board's memory-controller rules dictate which slots must be filled first for full 512GB recognition.

Do these registered ECC modules require any firmware updates or periodic maintenance after installation?

No firmware updates are needed for the memory itself; ECC error correction runs automatically, and the modules have no moving parts or heat spreaders that require servicing.
