This 2GB kit contains two 1GB DDR2 DIMMs built for the Dell OptiPlex GX520 series desktop. The modules run at 533 MHz with CL4 timing and 1.8V voltage. They install directly into the system's 240-pin slots.

Suits owners restoring a GX520

Buyers needing to reach the 4GB maximum or replace failed memory in this specific Dell model will find the correct fit. Systems requiring ECC, registered modules or a different DDR generation cannot use this unbuffered non-ECC kit.

240-pin DDR2 533 CL4 specification

The 240-pin DDR2 interface at 533 MHz with CL4 latency determines whether the modules match the motherboard slots. Verify that the target machine uses this exact generation and pin count before purchase.
