Buyers matching these exact Alienware models

The kit suits owners of an Area-51 R3, R4, R5, R6 or R7 who want a straightforward capacity increase. Systems that require ECC registered DIMMs or a different pin count cannot use this module. Builders working on any other platform should verify their motherboard specifications before purchasing.

2666 MHz CL19 DDR4 speed rating

The module operates at PC4-21300 with a CAS latency of 19. It is backward compatible with 2133 MHz and 2400 MHz memory controllers, so it will downclock automatically in slower systems. This speed grade is the single specification that confirms whether the part matches the motherboard's supported memory profile.
