Eight 32 GB DDR3L 1333 ECC registered RDIMMs deliver 256 GB at 1.35 V for servers and workstations
Capacity 256GB (8 x 32GB)
Rank 4Rx4
This kit provides 256GB of DDR3L ECC Registered memory across eight 32GB modules. It is built for workstations, servers, NAS systems and routers that require 240-pin RDIMMs. It will not work in standard desktop computers and cannot be mixed with unbuffered memory.
The modules run at 1.35V with a CL9 latency at 1333MHz, conforming to JEDEC PC3L-10600 specifications. ECC and registered buffering maintain data integrity during continuous workloads. The dual-channel kit configuration supports stable throughput in qualified multi-socket platforms.
Each DIMM uses the standard 240-pin DDR3L form factor without a heat spreader. Verify that the target system explicitly supports 4Rx4 Registered ECC modules before purchase. Incorrect platform selection is the most common reason these modules fail to post.

同系列產品,記憶體、散熱器或時脈不同 — 下單前請先比較。
Each module operates at 1.35V, lower than standard DDR3, reducing heat and power draw in 24/7 server or workstation deployments.
A workstation or server board with 240-pin DDR3L slots, registered ECC support, and 4Rx4 rank handling is required; desktop boards will not work.
No — registered ECC modules cannot be mixed with unbuffered memory; all slots must use matching registered ECC DIMMs for stability.
