512 GB DDR4 ECC RDIMM kit for SuperMicro WRX80

This 512 GB kit contains four 128 GB DDR4 3200 registered DIMMs with ECC and a CL22 latency. It is built for the SuperMicro M12SWA-TF WRX80 motherboard and targets professionals who need maximum memory capacity in a single workstation or server platform.

DDR4 3200 registered ECC limits

The modules run at DDR4 3200 (PC4-25600) with a 1.20 V operating voltage and a 4Rx4 organisation. Registered buffering and ECC add latency overhead, so raw bandwidth is lower than unbuffered consumer memory at the same clock. The 288-pin form factor fits only DDR4 RDIMM slots; it will not work in UDIMM, SO-DIMM or DDR5 sockets.

Check motherboard slot count and CPU support

Verify that the M12SWA-TF WRX80 board has at least four free DDR4 RDIMM slots and that the installed processor supports 4Rx4 registered modules at this capacity. Confirm the BIOS is updated to a version that recognises 128 GB per DIMM. Systems limited to lower densities or unbuffered memory cannot use this kit.

Questions about this item

Should I choose the 4x128GB kit or a different capacity for my SuperMicro M12SWA-TF WRX80?

The kit provides 512GB total across four 128GB RDIMMs, matching the board's eight-channel design when fully populated.

What does DDR4 3200 CL22 mean for real workloads on this platform?

The modules run at 3200MT/s with 22-cycle CAS latency, delivering registered ECC stability for multi-threaded server tasks.

How does the 288-pin RDIMM interface limit speed or capacity on this motherboard?

The 288-pin DDR4 RDIMM slot caps at 3200MT/s and supports 4Rx4 organisation, so this 128GB-per-module kit fits the electrical and physical limits.
