OWC 128GB DDR4 3200 ECC RDIMM

This 128GB DDR4 3200 ECC Registered DIMM is built for ASRock Open 19 server and workstation platforms including the 1U-Open19-c3.Medium.x86, 1U-Open19-m3.Large.x86 and 2U-Open19-m3.XLarge.x86 models. It suits administrators expanding memory capacity in compatible 1U or 2U systems. Desktop PCs and consumer motherboards cannot use this module.

128GB single module capacity and speed headroom

The module delivers 128GB in a single 288-pin RDIMM operating at 3200MHz CL22 (PC4-25600) and 1.2V. It is backward compatible with 2133MHz, 2400MHz, 2666MHz and 2933MHz bus speeds, automatically clocking down when the platform requires it. The 8Rx4 organisation provides high density but prevents mixing with unbuffered or load-reduced ECC memory.

Registered ECC build with JEDEC compliance

The stick uses a registered ECC design without a heat spreader, relying on server chassis airflow for cooling. JEDEC-standard and RoHS-compliant construction ensures a warranty-safe upgrade that meets OEM specifications. The 288-pin RDIMM keying fits only registered ECC slots, so it will not seat in standard unbuffered DIMM sockets.

商品問答

Will the 128GB DDR4 3200 ECC RDIMM run reliably alongside my existing 2133MHz or 2666MHz DDR4 modules?

Yes, the module is backward compatible with 2133MHz, 2400MHz, 2666MHz and 2933MHz DDR4 speeds. When mixed, all modules operate at the speed of the slowest installed DIMM.

How can I verify the 128GB 8Rx4 registered ECC module is functioning correctly after installation?

Check the system BIOS or UEFI to confirm 128GB is detected at 3200MHz with ECC active. Run a memory diagnostic such as MemTest86 to validate error-correction operation.

Does the 3R2D48R4128G package include a single 128GB 288-pin RDIMM only, or are extra items supplied?

The upgrade consists of one 128GB DDR4 3200 PC4-25600 CL22 8Rx4 288-pin 1.2V ECC Registered RDIMM. No cables, brackets or additional accessories are included.
