Product Features
Product Overview
The AddOn A2578600-AA is a 2GB DDR2-800MHz SODIMM memory module engineered as a compatible replacement for select Dell notebook systems. This module delivers reliable performance for older hardware that requires DDR2 memory technology, offering a straightforward upgrade path for systems where maximum supported capacity and speed are constrained by platform limitations.
Built with 200-pin SODIMM architecture, this memory is physically designed for notebook and small-form-factor applications. Its unbuffered, non-ECC design aligns with standard consumer and business notebook requirements, while the dual-rank configuration provides stable operation at the specified 800 MHz speed with CL6 latency. The module operates at 1.8V, matching the power profile of contemporary DDR2 platforms for energy-efficient performance.

Technical Overview
This memory module implements DDR2 SDRAM technology, which doubles the data transfer rate per clock cycle compared to original DDR. The 800 MHz effective speed corresponds to a 400 MHz clock frequency, delivering a peak transfer rate of 6.4 GB/s on a 64-bit bus. The PC2-6400 designation confirms compliance with the JEDEC standard for this performance tier.
The module's electrical characteristics include a 1.8V operating voltage, which reduces power consumption and heat generation compared to earlier memory technologies. The CL6 (CAS Latency 6) timing indicates the number of clock cycles between a column address strobe and data availability, balancing responsiveness with the module's speed class. The unbuffered design means signals pass directly to the memory controller without intermediate buffering, which is typical for non-server applications.

FAQ
What is the capacity and speed of this memory module?
This AddOn memory module provides 2GB of capacity with an 800 MHz speed rating, which corresponds to the DDR2-800/PC2-6400 standard. The 800 MHz represents the effective data rate, with the actual clock frequency being 400 MHz. This speed was common for mid-range to high-end DDR2 systems and provides adequate bandwidth for the compatible notebook platforms.
Is this memory ECC or non-ECC?
This is a non-ECC (Error-Correcting Code) memory module. Non-ECC memory does not include the additional circuitry to detect and correct single-bit memory errors, which is standard for consumer and business notebook systems. The module is also unbuffered, meaning it connects directly to the memory controller without intermediate registers, which is typical for non-server applications.
What does dual-rank mean for this SODIMM?
Dual-rank means the memory module has two sets of memory chips that are accessed separately, with only one rank active at a time. This configuration can improve memory controller efficiency in some systems compared to single-rank modules. For this 2GB DDR2 SODIMM, the dual-rank design helps achieve the specified capacity while maintaining compatibility with the memory controllers in supported Dell notebook systems.
Which Dell notebook models are compatible with this memory?
This module is compatible with specific Dell Precision Mobile Workstations (M2400, M4300, M4400, M6300), Latitude notebooks (D630, D630c, D830, E5400, E5500, E6400, E6500, XFR D630, 2110), Inspiron models (11z, 14, 17, 1750, 400, Zino HD, Mini 10v, Mini 9, XPS M1530, XPS M1730, Zino), Vostro systems (1014, 1088, 1200-1720, 2510, A840, A860), and Studio 15 (1535-1555) notebooks. Always verify your specific model's memory requirements before purchase.
What is the CAS latency and why does it matter?
This module has a CAS latency of CL6, which means it takes 6 clock cycles between when a column address is sent and when the corresponding data is available. Lower CAS latencies generally mean faster response times, though the actual impact depends on the memory controller and workload. CL6 was a common latency for DDR2-800 memory and represents a balance between speed and stability for the technology generation.
Can I mix this module with existing memory in my system?
While possible in some cases, mixing memory modules with different specifications (capacity, speed, timings, or rank) can lead to system instability or cause all modules to run at the speed of the slowest module. For optimal performance and reliability, it's recommended to use identical modules with matching specifications. If upgrading, consider replacing all memory modules with matched sets to ensure compatibility and stable operation.
