OWC 256GB DDR4 3200 ECC RDIMM

This OWC module is a 256GB DDR4 3200 PC4-25600 CL22 8Rx4 288-pin 1.2V ECC Registered RDIMM. It is built for the ASRock WRX80 Creator and WRX80 Creator R2.0 workstation platforms. The single DIMM delivers high-capacity registered memory with error correction for server and workstation workloads.

Suited for WRX80 workstations.

This memory suits administrators upgrading or populating ASRock WRX80 Creator R2.0 systems with matched, high-density ECC Registered modules. It will not work in standard desktop computers that require unbuffered non-ECC memory. Builders needing load-reduced ECC or unbuffered DIMMs must select a different memory type.

256GB octal-rank registered DIMM decides fit

The decisive specification is the 256GB octal-rank ECC Registered RDIMM form factor. The motherboard must support 8Rx4 registered modules at this density and the PC4-25600 speed grade. Verify the platform qualified vendor list for Samsung M393ABG40M52-CAE, Hynix HMAT14JXSRB120N, HMAT14JXSRB122N, or Supermicro MEM-DR425MI-ER32 cross-reference before purchase.

Questions about this item

How do I install the 288-pin ECC Registered RDIMM into the ASRock WRX80 Creator R2.0, and what step is commonly missed?

Align the single notch on the 288-pin RDIMM with the slot key, press straight down until both side clips click, and verify the module sits fully seated; the step often missed is confirming the motherboard sees all 256 GB at 3200 MT/s in BIOS before closing the case.

What maintenance or replacement will the 256 GB DDR4 3200 CL22 8Rx4 module need later?

No periodic maintenance is required; if a module fails, replace it with an identical 256 GB DDR4 3200 PC4-25600 CL22 8Rx4 1.2 V ECC Registered RDIMM to keep rank count, voltage and timing matched across channels.

What limit appears first when the 8Rx4 octal-rank RDIMM runs sustained workloads on the WRX80 Creator R2.0?

The memory controller’s maximum supported rank-per-channel limit is reached before thermal or bandwidth ceilings, so population rules in the board manual dictate how many 8Rx4 modules can run at the rated 3200 MT/s.
