A 128GB quad-channel DDR3L 1066 ECC registered server memory kit of four 32GB modules at 1.35V
Capacity 128GB (4 x 32GB)
Rank 4Rx4
This 128GB kit contains four 32GB DDR3L modules rated at 1066MHz PC3L-8500 with CL7 latency. Each 240-pin DIMM operates at 1.35V and uses 4Rx4 registered ECC technology. The memory is designed for compatible workstations, servers, NAS systems and routers that require registered error-correcting modules.
The modules run at the low 1.35V DDR3L voltage, reducing power draw compared to standard 1.5V DDR3. No heat spreaders are fitted, so airflow across the bare PCB handles cooling. Registered buffering adds minimal latency while maintaining signal integrity across all four slots in typical server workloads.
This kit only works in systems that support DDR3L registered ECC DIMMs; it will not function in standard desktop computers or alongside unbuffered memory. Buyers needing non-ECC or unregistered modules for consumer platforms must choose a different product.

同系列產品,記憶體、散熱器或時脈不同 — 下單前請先比較。
Populate identical modules in matched channel pairs — typically slots 1 and 3 for channel A, 2 and 4 for channel B — and never mix the 4Rx4 registered DIMMs with unbuffered memory.
No routine maintenance is required; keep air paths clean and replace only if a module fails ECC scrubbing or the platform is upgraded beyond DDR3L.
Memory bandwidth at PC3L-8500 saturates before the 1.35 V thermal envelope becomes a constraint.
