256GB DDR4 3200 ECC RDIMM Kit

This 256GB kit provides eight-rank registered DDR4 memory with ECC for Supermicro X12QCH+ servers. It runs at 3200 MT/s with CL22 latency at 1.2V. The registered design and error correction suit multi-socket workloads that demand full-capacity stability.

Verify Motherboard Population Rules

Confirm the X12QCH+ manual for approved DIMM population order and maximum supported capacity per slot before ordering. The board requires 288-pin RDIMM modules; UDIMM or SODIMM variants will not fit or function. Ensure the BIOS revision matches the vendor's qualified vendor list for this speed and rank configuration.

Replaces Lower-Capacity or Unbuffered Modules

The upgrade is worthwhile when moving from smaller RDIMM kits or from unbuffered ECC memory that cannot fill every slot at rated speed. Registered 8Rx4 architecture offloads the memory controller, allowing full population without downclocking. It does not suit platforms limited to UDIMM or single-rank configurations.

Questions about this item

Does the 256GB kit come as a single 288-pin RDIMM or do I need to buy additional modules?

The package content lists a 256GB DDR4 3200MHz PC4-25600 8Rx4 1.2V 288-pin ECC RDIMM kit, so the full capacity is included in one box.

Should I choose the 8Rx4 CL22 version or a different rank and latency for my Supermicro X12QCH+?

The 8Rx4 CL22 1.2V specification matches the exact rank, voltage and timing the X12QCH+ memory controller expects for full-capacity recognition at rated speed.

What does the PC4-25600 rating mean once the RDIMM is installed in the server?

PC4-25600 indicates a DDR4-3200 data rate; the registered ECC module will run at that speed with CL22 latency while correcting single-bit errors on the fly.
