8 GB DDR4-2666 UDIMM for desktop upgrades

This 8 GB DDR4-2666 UDIMM adds memory to desktop systems that accept standard non-ECC modules. It is built for users who need a straightforward capacity increase without server-grade features. The single-rank design fits typical consumer motherboard slots. Buyers who require ECC error correction or registered buffering should look elsewhere.

DDR4-2666 speed ceiling and 1.2 V operation

The module runs at the DDR4-2666 data rate, which is the practical limit of this memory standard at 1.2 V. Systems that only support lower DDR4 speeds will downclock the module automatically. No higher DDR4 frequencies or lower-voltage modes are available with this part. Builders needing faster memory must choose a different specification.

Replaces OEM part AA101752 in compatible desktops

This unit is the direct equivalent of OEM part number AA101752, using the same major-brand components the original vendor supplies. It restores or expands the factory memory configuration when the original modules are missing or insufficient. The upgrade is worthwhile when the system still meets the user's workload but needs more capacity.

Questions about this item

Should I pick the 8GB DDR4-2666 UDIMM or a different capacity?

This module is an 8GB stick. Choose it when your board has a free UDIMM slot and you want to add exactly 8GB.

What does the 2666 MHz rating deliver in a real desktop?

The DIMM runs at 2666 MHz with a PC4-21300 bandwidth rating, giving the memory controller that peak data rate when the system is configured to the rated speed.

Is the PC4-21300 label the same as DDR4-2666, and what does it cap?

Yes — PC4-21300 is the JEDEC designation for DDR4-2666. The module operates at 1.2V and is non-ECC, so it fits standard desktop UDIMM slots that support that speed.
