Dell OptiPlex GX520 memory upgrade

This 240-pin DDR2 module delivers 2 GB of system-specific memory for the Dell OptiPlex GX520 series desktop. It operates at 533 MHz (PC2-4200) with CL4 timing and 1.8 V voltage. The unbuffered, non-ECC stick uses a 2Rx8 rank configuration with major brand chips. It installs directly into one of the two available DIMM sockets.

Suited for restoring or maintaining a GX520

This upgrade suits owners of a Dell OptiPlex GX520 needing to replace a failed stick or reach the 4 GB platform maximum. The single-module kit fills one slot and is guaranteed compatible by the manufacturer. Builders requiring ECC error correction, registered buffering or speeds beyond DDR2-533 should look at other memory types. The lack of a heat spreader also makes it unsuitable for overclocked configurations.

DDR2-533 (PC2-4200) speed grade

The decisive specification is the DDR2-533 (PC2-4200) rating with CL4 4-4-4 timing. The motherboard must support this exact speed and voltage combination for the module to function. Verify that the target system accepts 240-pin unbuffered non-ECC DIMMs at 1.8 V before purchase. Mismatched speed or voltage will prevent the computer from booting.

Questions sur cet article

Does the 1.8 V DDR2 module run hot or draw much power when the Dell OptiPlex GX520 is on all day?

Standard DDR2 at 1.8 V is low-power and passively cooled; the stick has no heat spreader, so case airflow is all it needs for continuous operation.

What must the Dell OptiPlex GX520 already have for this 240-pin DIMM to work?

The GX520 needs a free 240-pin DDR2 slot and a BIOS that accepts 533 MHz CL4 unbuffered non-ECC memory; the system ships with two such sockets.

Will this 533 MHz CL4 stick run correctly beside the original 4200-speed memory in my GX520?

Yes — the module matches the PC2-4200 533 MHz CL4 spec of the factory DIMMs, so both sticks will operate at the same speed and timings.
