Dual 32 GB DDR4 2666 ECC SODIMM kit adds 64 GB to compatible ASUSTOR NAS models
Capacity 64GB (2 x 32GB)
This OWC kit supplies 64GB of DDR4 2666 ECC memory in two 32GB modules. It uses 260-pin SODIMM form factor, runs at 1.2V with CL19 latency, and is validated for specific ASUSTOR NAS models including the 6504, 6508, 6510 and 6512 series.
Builders expanding an ASUSTOR 6504, 6508, 6510 or 6512 unit to 64GB will find this kit a direct fit. It is not for systems that require registered DIMMs, non-ECC memory, or 288-pin desktop modules, nor for platforms limited to lower maximum capacities.
The kit delivers 64GB of ECC-protected DDR4 2666 bandwidth, with backward compatibility to 2400 and 2133 speeds. It fills both SODIMM slots on compatible ASUSTOR units, so further expansion would require replacing modules rather than adding to them.
