Purpose-built server memory kit

This 128 GB kit contains two 64 GB DDR4 RDIMMs rated at 3200 MT/s with CL22 timings and 1.20 V operation. The modules are registered, ECC-enabled, and organised as 2Rx4 to match the Supermicro X12QCH+ motherboard's requirements. They arrive new and ready for installation in 288-pin slots.

Registered DDR4 limits at full population

Registered DDR4 offloads electrical load from the memory controller, allowing every slot to be populated without signal degradation. The trade-off is one extra clock cycle of latency compared with unbuffered modules and a hard requirement for motherboard support of the RDIMM pinout. ECC corrects single-bit errors on the fly, but cannot fix multi-bit failures.

Replaces smaller or unbuffered kits

Upgrading from lower-capacity RDIMMs or from UDIMMs that the board cannot recognise eliminates capacity ceilings and boot-time mismatches. The jump is worth it when workloads need the full 128 GB at rated speed and the system manual confirms the 2Rx4 population rule. Builders needing more than two modules per channel or non-ECC memory should look elsewhere.

Questions sur cet article

Should I choose the 2x64GB kit or look for a different capacity for my Supermicro X12QCH+?

The 128GB kit provides two 64GB RDIMMs that match the board's 288-pin DDR4 slots and registered ECC requirement; other capacities would need the same 2Rx4 rank, 1.20V voltage and CL22 timing to be recognised at full speed.

What does the DDR4-3200 CL22 rating mean once the modules are installed in the server?

The memory controller will run each DIMM at 3200 MT/s with a CAS latency of 22 cycles at 1.20V, delivering the rated PC4-25600 bandwidth while ECC corrects single-bit errors on the fly.

How does the 288-pin RDIMM interface limit what I can install?

Only 288-pin DDR4 registered DIMMs fit the X12QCH+ slots; UDIMMs, SODIMMs or any other generation will not seat, and the board's population rules require matching 2Rx4 rank and 1.20V operation.
