Blazing Memory BM4GD2800S 4GB DDR2 SO-DIMM 200-pin accessory

SKU CH-WYX5-W49H6

4GB DDR2 SO-DIMM laptop memory module running at 800 MHz with CL5 latency and 1.8 V operation

  • Adds 4 GB of DDR2 memory running at 800 MHz
  • PC2-6400 bus speed matches legacy laptop requirements
  • Single 200-pin SO-DIMM module fits one slot
  • Operates at standard 1.8 V DDR2 voltage
  • Non-ECC unbuffered design for consumer notebooks

DDR2 SO-DIMM upgrade for older laptops

This 4 GB module uses DDR2 SDRAM at 800 MHz with a 200-pin SO-DIMM form factor. It fits notebooks that accept PC2-6400 unbuffered memory running at 1.8 V. The single stick adds capacity to systems with two available slots.

Low-voltage operation keeps thermals modest

At 1.8 V the module draws little power and produces minimal heat inside a cramped chassis. CL5 latency and unbuffered design add no active cooling requirement. Fan noise and battery impact stay negligible during everyday workloads.

Replaces smaller DDR2 sticks in dual-slot notebooks

The jump is worthwhile when a 32-bit OS limits usable memory to 3.0 or 3.5 GB and a 64-bit OS can address the full 4 GB. Buyers needing more than 4 GB total or a faster memory standard cannot use this module.

Questions about this item

How do I install the 200-pin SO-DIMM and what step is often missed?

Align the notch on the module with the key in the slot, press firmly at both ends until the side clips snap shut; the step often missed is pressing evenly on both corners so both clips engage.

What maintenance or replacement will this DDR2 module need later?

No routine maintenance is required; replacement is only necessary if the module fails or if the system is upgraded to a platform that no longer supports DDR2 memory.

What limit appears first under sustained use with the 1.8 V supply?

The thermal limit of the unbuffered DDR2 chips is reached first; prolonged heavy loads can raise module temperature until the system throttles or shuts down to protect the components.
