Alienware X51 memory upgrade

This 4GB DDR3 module is built specifically for the Alienware X51 desktop. It delivers a straightforward capacity increase for owners of that system who need more memory for everyday multitasking. The JEDEC-standard design ensures compatibility without requiring configuration changes.

Single 240-pin UDIMM fits existing slot

The unbuffered non-ECC DIMM installs directly into a standard 240-pin DDR3 slot on the X51 motherboard. No heat spreader is fitted so clearance stays minimal inside the compact chassis. The 1.5V operating voltage matches the platform's stock memory power rail.

Steady throughput at CL9 1333MHz

Rated at PC3-10600 with CAS latency 9, the module maintains consistent bandwidth during extended workloads such as large file edits or multi-tab browsing. The 2Rx8 organisation supports stable dual-rank operation without throttling under sustained use.

Perguntas sobre este artigo

Will the 1333 MHz DDR3 speed limit throughput during long sessions?

The module runs at the standard DDR3 1333 (PC3-10600) rate with CL9 latency, so bandwidth is capped at that specification during sustained use.

Does the stick run hot or draw extra power when the Alienware X51 is on all day?

It operates at the standard 1.5 V without a heat spreader and is unbuffered non-ECC, so thermal output and power draw stay within normal DDR3 limits.

What must the Alienware X51 already have for this 240-pin UDIMM to work?

The system needs a free 240-pin DDR3 DIMM slot that accepts 1.5 V unbuffered non-ECC memory; the X51 desktop platform provides that.
