Single 128GB DDR4 ECC RDIMM

This OWC module provides 128GB of DDR4 3200 registered ECC memory in a single 288-pin DIMM. It operates at 1.2V with CL22 latency and an 8Rx4 organisation. The part is validated for Supermicro A+ Server models 1014S-ACR12N4H, 1024US-TNR, 1024US-TRT, 1114CS-TNR and 1114S-WN10RT.

Suits servers needing maximum capacity per slot

Administrators expanding Supermicro A+ systems with registered ECC DDR4 will use this module. It cannot be mixed with unbuffered or load-reduced DIMMs and will not function in standard desktop platforms. Buyers who need unbuffered memory or desktop-compatible speeds should look elsewhere.

128GB density in one registered DIMM

The 128GB capacity per module lets you reach very high memory totals using fewer slots. This density is the decisive factor when planning large-memory configurations on the supported Supermicro platforms.

Questions about this item

Should I pick a single 128GB module or combine smaller DIMMs for the 8Rx4 configuration?

This part is a single 128GB DDR4 3200 CL22 8Rx4 288-pin ECC Registered RDIMM; the 8Rx4 rank structure is already built into this one module.

What does the 3200MHz CL22 rating deliver inside a Supermicro A+ Server?

It runs at DDR4 3200 (PC4-25600) with CAS latency 22 at 1.2V, and will down-clock to 2933, 2666, 2400 or 2133MHz if the platform requires it.

Does the 288-pin ECC Registered interface limit maximum capacity per slot?

The module uses the standard 288-pin DDR4 ECC Registered RDIMM form factor; capacity per slot is determined by the Supermicro server's memory controller and qualified DIMM list.
