DDR2 SO-DIMM upgrade kit

This 4 GB kit contains two 2 GB DDR2 SO-DIMM modules that run at 533 MHz with a CAS latency of CL4. It is built for laptops, notebooks and all-in-one computers that accept 200-pin DDR2 memory and need a straightforward capacity increase.

Dual-channel kit for DDR2 platforms

The matched pair enables dual-channel operation on systems with two available SO-DIMM slots, freeing a single slot if the board has three or leaving both slots filled on two-slot designs. Each module operates at the standard 1.8 V DDR2 voltage and is non-ECC unbuffered, so it fits the electrical requirements of mainstream DDR2 mobile platforms without registration or error-correction overhead.

Standard DDR2 power and thermals

At 1.8 V the modules draw the normal power envelope for DDR2 SO-DIMM parts, producing modest heat that is handled by the laptop's existing thermal solution. No additional cooling or higher-wattage power supply is required beyond what the original system provides for its memory subsystem.

Questions about this item

Will the 533 MHz DDR2 speed become the bottleneck during long rendering sessions?

The kit runs at DDR2 533 (PC2-4200) with CL4 latency; sustained bandwidth is capped at that rate, so heavy workloads will hit the memory throughput ceiling first.

How much heat does the 1.8 V unbuffered SO-DIMM produce when the laptop runs all day?

Standard 1.8 V DDR2 SO-DIMMs generate modest heat; the modules are unbuffered and non-ECC, so thermal output stays low enough for typical laptop cooling.

Does my notebook need a 200-pin DDR2 slot and dual-channel support to use both 2 GB sticks?

Yes — the kit requires two 200-pin DDR2 SO-DIMM sockets and a chipset that can run dual-channel at 533 MHz.
