Dell desktop memory upgrade

This Dell AA101752 module adds 8 GB of DDR4 2666 memory to compatible Dell desktops. It targets owners of the listed Alienware, OptiPlex, Precision and Vostro models who want a straightforward capacity increase. The unbuffered, non-ECC design matches the original specification for these systems. Buyers with non-Dell platforms or laptops cannot use this part.

288-pin DDR4 2666 (PC4 21300) specification

The module runs at DDR4 2666 with a PC4 21300 rating and operates at 1.20 V. This exact speed and voltage combination is the single detail that decides whether the memory will be accepted by the supported Dell motherboards. Systems requiring a different DDR generation, a higher or lower data rate, or registered ECC modules will not work with this stick.

Designed-for list covers specific Dell models

The manufacturer highlights confirm compatibility with Alienware Area-51 R6 and Aurora R7, OptiPlex 3060, 5060, 7060 and XE3, Precision 3430 Small Form Factor and 3630 Tower, plus Vostro 3470 and 3670. No additional accessories, software or heat-spreader are bundled. Buyers needing support for other Dell lines or custom-built PCs must verify suitability separately.

Questions about this item

Will 2666 MHz actually run at that speed in my Alienware Aurora R7?

The module is rated DDR4 2666 (PC4 21300) and will operate at 2666 MHz if the motherboard supports that data rate; otherwise it downclocks to the highest speed the platform allows.

Does the 288-pin DDR4 interface limit bandwidth on a Precision 3630 Tower?

The 288-pin DDR4 form factor delivers the full PC4 21300 bandwidth ceiling; the platform's memory controller determines the final throughput.

Will this 8 GB stick fit the DIMM slots in a Vostro 3670 small chassis?

Yes — it is a standard 288-pin unbuffered DDR4 DIMM designed for the Vostro 3470 and 3670, so it fits the regular desktop memory slots.
