2GB DDR2 200-Pin SODIMM RAM – PC2-6400 800MHz 1.8V Non-ECC

Notebook Memory Module for Legacy Laptop Upgrades

The 2GB DDR2 200-Pin SODIMM is a single PC2-6400 module for notebooks carrying a 200-pin small-outline slot. It runs at 800 MHz with a 6.4 GB/s peak transfer rate. The module is non-ECC and unbuffered at 1.8 V.

JEDEC timing runs CL5 at 800 MHz, with tighter latencies available at reduced clock speeds. The 256M x 64 organisation drives a 64-bit data bus from one module. A gold-plated edge connector carries the 200 contacts across the SO-DIMM footprint. PCB height stays at 30 mm, which clears low-profile laptop bays and mini-PC chassis.

Fit the module to DDR2-generation Intel and AMD notebooks that specify PC2-6400 or PC2-5300. Mixed speeds default to the slowest module in the channel. Install matched pairs where the mainboard supports dual-channel operation. Discharge static before handling, then seat the board at roughly 30 degrees until the retention clips latch.

Compatibility depends on the notebook chipset, not the module alone. Check the service manual for maximum capacity per slot and supported DDR2 speed grades before ordering. Some older platforms accept 2 GB per slot, while others cap at 1 GB. A BIOS update sometimes widens support for higher-density modules. Record the existing module label so the new part matches voltage and rank.

Key Features

• PC2-6400 Speed Grade
  Rated for 800 MHz operation with 6.4 GB/s peak bandwidth.

• 200-Pin SO-DIMM Footprint
  The small-outline edge connector seats in notebook memory slots only.

• Low Voltage Operation
  The module runs at 1.8 V, the standard DDR2 supply rail.

• Signal Integrity Details

  • Gold-plated contacts resist corrosion across repeated reseating
  • 30 mm PCB height clears slim chassis and access panels
  • Unbuffered, non-ECC design matches consumer notebook chipsets

• Single-Module Upgrade
  One 2 GB board doubles capacity on notebooks fitted with a 1 GB stick.

• Backward Speed Compatibility
  The board clocks down to PC2-5300 and PC2-4200 bus speeds where required.

Why Choose This Notebook Module

• The DDR2-800 speed grade matches common Core 2 Duo and Turion notebooks.

• PC2-6400 memory trades down cleanly on boards limited to 667 MHz.

• A single 2 GB SO-DIMM restores usable headroom on 32-bit and 64-bit installs.

• Gold contacts hold signal quality through repeated service visits.

• The 1.8 V rail keeps power draw inside the original thermal budget.

• Non-ECC unbuffered layout suits consumer chipsets without parity support.

• Anti-static packaging protects the board during storage and transport.
