A 64GB dual-channel DDR4 2933MHz ECC SODIMM kit with CL21 timing and 1.2V operation for compatible laptops, all-in-ones and NAS systems
Capacity 64GB (2 x 32GB)
This 64 GB kit contains two 32 GB DDR4 2933 MHz CL21 modules built to JEDEC PC4-23400 specifications. They operate at 1.2 V and include on-die error-correcting code for data integrity in compatible laptops, all-in-one PCs and NAS appliances.
The unbuffered 260-pin design works in platforms that support DDR4 ECC SO-DIMMs, such as micro-servers and point-of-sale units. Systems without ECC support in the memory controller will not benefit from the error-correction feature and should use non-ECC memory instead.
The decisive specification is the 2933 MHz CL21 ECC profile at 1.2 V; the kit will down-clock to 2666 MHz, 2400 MHz or 2133 MHz where required, but the platform must accept DDR4 ECC SO-DIMMs for the modules to function.

Same family, different memory, cooler or clock — compare before you commit.
Yes, both 32GB modules are 260-pin DDR4 SO-DIMMs that fit standard laptop memory sockets.
Align the notch on the module with the key in the slot, press down firmly until the side clips click, and verify both sticks are fully seated for dual-channel operation.
Yes, the modules are backwards compatible with 2666MHz, 2400MHz and 2133MHz while retaining ECC capability at those lower speeds.
