FAQ
What is the capacity and technology of this memory module?
This AddOn memory module provides 4GB of capacity using DDR3 SDRAM technology. It operates at 1333MHz with a DDR3-1333/PC3-10664 memory standard, making it suitable for systems requiring moderate memory capacity with DDR3 compatibility.
Does this memory support ECC and what are the benefits?
Yes, this module features Error-Correcting Code (ECC) support. ECC automatically detects and corrects single-bit memory errors, improving data integrity and system stability. This makes the module suitable for applications where memory accuracy is critical, such as financial systems, databases, and medical equipment.
What does unbuffered dual-rank mean for this memory?
Unbuffered means the memory communicates directly with the memory controller without intermediate buffering, reducing latency compared to registered modules. Dual-rank organizes the memory chips into two independent groups, allowing more efficient memory access and better bandwidth utilization than single-rank designs.
What form factor and pin count does this module use?
This module uses the UDIMM (Unbuffered Dual In-line Memory Module) form factor with 240 pins. This is the standard physical design for most desktop and workstation DDR3 memory, ensuring compatibility with standard memory slots without requiring specialized hardware.
What is the operating voltage and why does it matter?
This memory operates at 1.35V, which is lower than the standard 1.5V for DDR3 modules. The reduced voltage decreases power consumption by approximately 10%, resulting in less heat generation and potentially longer component lifespan. This makes the module suitable for energy-efficient systems and environments where thermal management is important.
What systems is this memory compatible with?
This AddOn A4987240-AM module is factory-original and compatible with Dell systems designed for the A4987240 memory specification. It requires a system with DDR3 memory slots supporting unbuffered ECC modules at 1333MHz. Always verify your system's specific memory requirements before installation to ensure compatibility.
