⚡ Engineering Highlights at a Glance:

• 4GB Single Module (1x4GB): Ideal for upgrading older desktop systems running DDR3 platforms.
• DDR3L-1600 MHz Speed: Standard frequency for DDR3 systems, designated PC3-12800.
• 1.35V Low Voltage: DDR3L operation reduces power consumption compared to standard 1.5V DDR3.
• CL11 Latency: 11-11-11 timing for stable performance.
• 1Rx8 Single-Rank Organization: Built with 8 FBGA 512Mx8 DRAM components (512Mx64 organization).
• Non-ECC Unbuffered: Standard UDIMM design for desktop motherboards.
• JEDEC Compliant: Fully compliant to JEDEC standards for guaranteed compatibility.
• 240-Pin DIMM: Standard form factor for DDR3 desktop memory slots.

Platform Compatibility

The Crucial 4GB DDR3L 1600MHz UDIMM is a 240-pin DDR3 DIMM designed for desktop motherboards with DDR3 slots. It is not compatible with DDR4 or DDR5 platforms. The module operates at 1.35V (DDR3L), which is lower than standard DDR3’s 1.5V. It is compatible with motherboards that support DDR3L memory, and often works in standard DDR3 slots as well. Ensure your motherboard supports DDR3L or DDR3 before purchase. Users report successful upgrades in systems such as Dell Optiplex 3020 and ASUS H81 motherboards.

🔧 Installation and Configuration

This is a single 4GB module (1x4GB), ideal for users who want to add 4GB to an existing system with 4GB already installed to reach 8GB total. For optimal performance, install the module in the recommended slot per your motherboard manual. The module features 1Rx8 single-rank organization with 8 FBGA 512Mx8 DRAM components. No XMP profile is required; the module runs at its rated 1600MHz speed automatically on compatible platforms.

⚙️ Performance Characteristics

The module delivers reliable performance for legacy DDR3 systems, suitable for office work, web browsing, and light tasks. The 1.35V low-voltage operation reduces power consumption compared to standard 1.5V DDR3. Adding 4GB to a system with 4GB already installed yields 8GB total, which is the best cost/benefit compromise for running Windows 10 or Windows 11 for basic internet and document work. The module is JEDEC compliant and backed by Crucial’s reputation for quality and reliability.

This single 4GB module is ideal for upgrading legacy DDR3 desktop systems; add it to a system with 4GB already installed to reach 8GB total. The module runs at 1600MHz with CL11 timing automatically on compatible platforms—no XMP profile is required. Verify your motherboard supports DDR3L (1.35V) or DDR3 (1.5V) memory before purchase. The 240-pin DIMM form factor is not compatible with DDR4 or DDR5 slots. Before installing, discharge static electricity by touching an unpainted metal surface. After installation, consider running Memtest86 to verify memory integrity. For improved system performance, consider replacing a traditional hard disk with an SSD. The limited lifetime warranty provides long-term peace of mind.
