Corsair 2GB SODIMM - Key does not fit Laptop

  Diala 21:17 28 Mar 2011


I have purchased a Corsair 2GB SODIMM DDR2 upgrade for my Lenovo T42 Laptop.

The Corsair SODIMM was to replace my Laptops 1GB Kingston SODIMM.

However, the Corsair SODIMM does not seem to fit into my Laptops expansion bay as the Key on the curcuit board does not line up with that of the expansion port key on the laptop, and therefore the SODIMM can not fit into the Laptop expension bay.

On comparing the Corsair SODIMM with the Kingston SODIMM, the Key (cut out on the two boards)I can see that the Corsair SODIMM key is fractionally in a different place to that of the Kingston SODIMM.

Can any one help and explain why the Key on the two SODIMMS differ? I would expect the key on them to line up precisely as they are the same spec SODIMM's?

Many thanks for your reply l24.

I should of ordered DDR SODIMM and not the DDR2 SODIMM, as the modules have a different "key" or notch in their connectors and are not compatible.

It's usually worth running the Crucial scanner which will determine what is fitted and suggest compatible upgrade. you con't have to buy it from them (although I usually do).
