OWC 128GB DDR4 3200 CL22 8Rx4 288-pin 1.2V ECC RDIMM 3R2D48R4128G

SKU CH-788W-XEQDA

A single 128GB DDR4 3200 CL22 8Rx4 288-pin 1.2V ECC registered RDIMM validated for Supermicro A+ Server 4124 series

  • Capacity128GB
  • Type288-Pin DDR4 ECC RDIMM
  • SpeedDDR4 3200 (PC4 25600)
  • CAS Latency22
  • Voltage1.2V
  • ECCYes
  • 128 GB capacity expands server memory for demanding workloads
  • DDR4 3200 speed with CL22 latency delivers high throughput
  • ECC registered design detects and corrects data errors
  • 2 V operation reduces power draw and heat
  • Validated for Supermicro A+ Server 4124 series compatibility

Targeted Server Upgrade

This 128GB DDR4 ECC registered DIMM is built for the Supermicro A+ Server 4124GO-NART, 4124GO-NART+, 4124GQ-TNMI, 4124GS-TNR and 4124GS-TNR+. It suits administrators expanding memory capacity in compatible workstation or server platforms that require registered error-correcting modules. It will not work in standard desktop computers or systems needing unbuffered or load-reduced memory.

Physical Build and Slot Fit

The module uses a 288-pin DDR4 form factor without a heat spreader, keeping the profile low for dense server chassis. A 1.2V operating voltage matches the JEDEC standard for DDR4 registered DIMMs. The single 128GB stick occupies one slot, leaving remaining sockets free for further expansion within the platform's limits.

Decisive Specification

The 8Rx4 rank configuration at CL22 latency and 3200MHz speed defines compatibility with the listed Supermicro models. Systems that cannot address 8Rx4 registered modules or that require a different rank structure will not support this part. Backward compatibility covers 2133MHz, 2400MHz, 2666MHz and 2933MHz bus speeds.

Kysymyksiä tästä tuotteesta

What does the DDR4 3200 PC4-25600 interface cap the transfer rate at in practice?

The module runs at DDR4 3200 (PC4-25600) with CL22 latency and will down-clock to 2133, 2400, 2666 or 2933 MHz if the server requires a lower speed.

What physical slot and clearance does this 288-pin ECC RDIMM need to fit?

It requires a standard 288-pin DDR4 DIMM socket; the module has no heat spreader so it fits in tight server chassis without extra clearance.

How is the module installed and what step do people often get wrong?

Align the notch with the socket key, press straight down until both latches click; the common mistake is mixing this registered ECC DIMM with unbuffered or load-reduced memory, which will not work.
