FOOTNOTES [Δ]
  1. The memory module that was shipped with this laptop had the same Micron logo as the modules from Crucial, which is a division of that company.
  2. Memory for T60p spec is CL5, but this module which was CL4 works fine. The product page at G.Skill describes it wrongly as a CL5 module.
  3. Some users reported the RAM module is in fact overclocked from 533MHz to 677MHz, hence some systems may report 533MHz and/or CL4
  4. Crucials website doesnt list Rendition memory, but the memory is clearly labelled as Crucial Rendition by several resellers
