OWC
Eight-module kit delivers 1 TB of DDR5 4800 ECC registered memory for Dell PowerEdge XE9680 servers
Capacity 1TB (8 x 128GB)
This OWC kit supplies 1TB of DDR5 memory across eight 128GB registered DIMMs. It is built for the Dell PowerEdge XE9680 server platform. The modules carry ECC and registered signalling for data integrity in multi-socket workloads. Standard desktop boards cannot use this memory.
The DIMMs run at the JEDEC-standard DDR5 4800 speed (PC5-38400) with a CAS latency of CL40. Registered buffering and 4Rx4 organisation keep signal quality stable across all eight slots during continuous server duty. Voltage is fixed at 1.1V. No heat spreaders are fitted, so chassis airflow must handle module cooling.
Each module is a 288-pin DDR5 RDIMM with 4Rx4 rank structure and ECC registered operation. The PowerEdge XE9680 requires this exact combination; unbuffered, load-reduced or different-rank DIMMs will not work. Verify the server memory guide before ordering.

同系列產品,記憶體、散熱器或時脈不同 — 下單前請先比較。
Each 128GB module operates at 1.1V, the standard JEDEC voltage for DDR5 4800, so total draw scales with the eight populated slots and the server's own power management.
The server needs eight free 288-pin DDR5 RDIMM slots and a BIOS that supports 4Rx4 registered ECC modules at 4800 MT/s; no other hardware is required.
No. The manufacturer states these registered ECC modules cannot be mixed with unbuffered or ECC load-reduced memory in the same system.
