OWC 4GB SODIMM for Dell Vostro 2421

This OWC module provides a 4GB DDR3L memory upgrade for the Dell Vostro 2421. It uses a 204-pin SODIMM form factor and operates at 1600 speed with CL11 latency. The single module delivers a straightforward capacity increase for the specified system.

Suitable for Vostro 2421 owners adding memory

Builders who need ECC error correction or registered modules should look elsewhere. This non-ECC unbuffered design does not support those requirements. Buyers needing a different capacity or voltage than 1.35V must choose another part.

Runs at 1.35V low voltage

The module operates at 1.35V, matching the DDR3L standard for reduced power draw. Verify that your Vostro 2421 accepts this voltage before purchase. A mismatched voltage will prevent the system from booting correctly.

Questions sur cet article

What does the 1600 speed rating mean for daily use in my Vostro 2421?

The module is rated at PC3L-12800, so the memory controller will read and write at up to 1600 MT/s; actual throughput depends on the laptop's chipset and any other installed modules.

How does the 204-pin DDR3L interface limit performance?

The 204-pin SODIMM form factor carries the DDR3L 1.35V signal; bandwidth is capped at the PC3L-12800 specification and the system cannot run faster memory.

Will this stick fit the memory slot in a Dell Vostro 2421?

Yes, it is a 204-pin unbuffered non-ECC SODIMM built to the exact physical and electrical spec for the Vostro 2421.
