Targeted DDR2 upgrade for Dell OptiPlex 755

This 4 GB kit delivers two matched 2 GB DIMMs built to the PC2-6400 800 MHz CL6 specification. It is engineered for the OptiPlex 755 desktop, mini-tower and small-form-factor chassis. The modules are non-ECC, unbuffered and operate at the standard 1.8 V DDR2 voltage.

Steady throughput at rated speed

Running at the full 800 MHz data rate with 6-6-6 timings, the pair maintains its CL6 latency during extended workloads rather than throttling after a short burst. The 2Rx8 organisation and major-brand chipset keep bandwidth consistent across the four or two slots populated in the host system.

Plain green PCB fits tight spaces

Without a heat spreader the low-profile sticks clear cramped SFF interiors and sit cleanly in 240-pin slots. The standard notch alignment prevents mis-insertion, and the two-piece kit lets you populate matching channels for dual-channel operation where the motherboard supports it.

Vprašanja o tem izdelku

How much power does the DDR2 800 CL6 kit draw when the Dell OptiPlex 755 runs all day?

The modules run at 1.8 V with no heat spreader, so power draw stays low and cooling relies on normal chassis airflow.

What must the Dell OptiPlex 755 already have for these 240-pin DIMMs to work?

The desktop needs two free 240-pin DDR2 slots and a motherboard that supports PC2-6400 800 MHz non-ECC unbuffered memory.

Will this 4 GB kit work alongside the original 2 GB sticks still in my OptiPlex 755?

Yes, if the board has four slots you can add this 2×2 GB kit to the existing pair, but total memory must not exceed the 8 GB or 4 GB limit for your chassis.
