1 GB DDR2-667 SO-DIMM module rated at 667 MHz with CL5 latency and 5.4 GB/s bandwidth

  • 1 GB DDR2 SO-DIMM for compatible laptops
  • 667 MHz PC2-5400 speed delivers 5.4 GB/s bandwidth
  • CL5 latency at 1.8 V for stable operation
  • 200-pin unbuffered non-ECC module fits standard DDR2 slots
  • 6-layer PCB with 128Mx8 BGA chips per side

1 GB DDR2-667 SO-DIMM for older laptops

This single 1 GB module runs at 667 MHz with CL5 latency and 1.8 V voltage. It uses a 200-pin DDR2 SO-DIMM form factor and delivers 5.4 GB/s bandwidth on a six-layer PCB. The double-sided design places four BGA chips per side in a 128Mx8 configuration. It arrives in retail packaging with a lifetime manufacturer warranty.

Non-ECC unbuffered laptop upgrade

The module is non-ECC and unbuffered, matching the requirements of most mainstream DDR2-era notebooks. Buyers whose systems demand ECC or registered memory should look elsewhere. It is also unsuitable for desktops or any platform that cannot accept a 200-pin SO-DIMM.

200-pin DDR2 SO-DIMM form factor

Compatibility hinges on the 200-pin DDR2 SO-DIMM interface; only laptops with a matching DDR2 slot can use this module. The 1 GB capacity and PC2-5400 speed rating are secondary to the physical and electrical interface. Verify the slot type before purchasing.
