DDR4 2666 8GB Desktop Upgrade Module

This A-Tech module delivers eight gigabytes of DDR4 memory rated at 2666 MT/s (PC4-21300). It uses a standard 288-pin DIMM form factor and operates at 1.2 V without ECC or registered buffering. The stick is built as a direct replacement for the Samsung M378A1G43TB1-CTD part and is tested for AMD and Intel desktop platforms.

Suits single-slot upgrades.

Builders adding a single 8 GB stick to a compatible DDR4 board will find this a straightforward capacity increase. Systems that require ECC error correction, registered modules, or matched multi-channel kits should look at alternative parts because this unit is non-ECC unbuffered and sold individually.

2666 MT/s DDR4 speed rating

The decisive specification is the DDR4 2666 (PC4-21300) speed rating; the motherboard and CPU memory controller must support this data rate for the module to run at its tested frequency.

Questions about this item

Should I buy the single 8GB module or look for a kit?

This listing is a single 8GB DDR4 2666 module; add a second identical stick later if your board supports dual-channel.

Will the 2666MHz speed actually run at that rate in my desktop?

The module is tested at 2666MHz and will operate at that frequency if the motherboard and CPU memory controller support it; otherwise it downclocks automatically.

Does the PC4-21300 label limit the bandwidth I can get?

PC4-21300 is the peak transfer rate for DDR4 2666, so the module cannot exceed that bandwidth in practice.
