64GB DDR3L ECC Kit for Workstations

This OWC kit delivers 64GB across eight 8GB unbuffered UDIMMs running at DDR3L 1600 with CL11 latency. The modules operate at 1.35V and include ECC for data integrity in workstations, servers and NAS systems. Each stick uses a 240-pin 2Rx8 layout and carries JEDEC and RoHS compliance.

Upgrade from lower-capacity DDR3 or non-ECC sets

Replacing smaller or non-ECC DDR3 kits with this 64GB configuration adds both capacity and error correction for workloads that demand stability. The jump is worthwhile when applications exceed current memory limits or when silent data corruption becomes a risk in multi-tasking or file-server roles.

DDR3L 1600 limits at 1.35V and 240-pin form factor

The DDR3L standard tops out at 1600 MT/s with 1.35V operation, so no higher speed grades exist within this voltage envelope. The 240-pin UDIMM form factor fits only platforms designed for DDR3 or DDR3L, and unbuffered ECC modules require chipset support for ECC to function.

Questions about this item

Will the 240-pin DDR3L UDIMMs fit my workstation's standard DIMM slots?

Yes, each module uses the 240-pin DDR3L UDIMM form factor that matches standard desktop, workstation and server DDR3 slots.

What is the correct way to seat all eight modules so the system recognises the full 64 GB?

Install the eight 8 GB sticks in matched pairs according to your motherboard's dual-channel layout, pressing each module down until the retention clips click on both sides.

Do these 1.35 V ECC modules need any firmware updates or periodic replacement?

No firmware is required; the JEDEC-standard DDR3L ECC UDIMMs run at 1.35 V for the life of the system unless a module fails, in which case only the faulty stick is swapped.
