Two green DDR2 laptop memory modules with gold contacts

Simmtec, Inc

Simmtec, Inc 8GB (2x 4GB) DDR2 667MHz PC2-5300/PC2-5400 SODIMM CL5 200-Pin 1.8V Unbuffered NON-ECC laptop RAM

SKU CH-PSK6-6MQ42

Dual-channel DDR2 kit delivers 8 GB of laptop memory at 667 MHz with CL5 latency on 200-pin SODIMMs

  • Total capacity8 GB (2 × 4 GB)
  • CAS latencyCL5
  • 8 GB total capacity from two matched 4 GB modules
  • 667 MHz DDR2 speed rated for PC2-5300 and PC2-5400 systems
  • CL5 latency for responsive access in compatible laptops
  • 8 V operation keeps power draw low for mobile use
  • 200-pin SODIMM form factor fits standard DDR2 laptop slots

8 GB DDR2 SODIMM kit

This kit supplies 8 GB of DDR2 laptop memory in two matched 4 GB modules. Each stick uses a 200-pin SO-DIMM form factor and runs at 667 MHz with PC2-5300/PC2-5400 ratings. Unbuffered, non-ECC operation and 1.8 V power make it a direct drop-in upgrade for compatible notebooks.

Suitable for DDR2 notebook upgrades

Owners of laptops that accept DDR2 SO-DIMMs at 667 MHz and CL5 latency can use this pair to reach 8 GB total capacity. Systems that require ECC, registered modules or a different pin count will not accept these sticks. Buyers needing more than 8 GB or a different voltage must look elsewhere.

CL5 latency at 667 MHz

The modules operate at CAS latency 5 across the 667 MHz data rate. This timing is the key compatibility figure; if the target machine demands a different latency the memory may not post or may run at reduced stability.

Questions about this item

What does the PC2-5300/PC2-5400 rating mean for real-world speed?

The kit runs at 667 MHz, so the DDR2 interface caps throughput at the PC2-5300/PC2-5400 level.

What slot and pin count does this kit require?

Each module uses a 200-pin SODIMM form factor made for DDR2 laptop sockets.

How do I install the two modules and what step is often missed?

Power off, remove the battery, open the memory door, insert each stick at the correct angle until the clips click, then reassemble before booting.
