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.

Fragen zu diesem Artikel
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.
