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
5. Due to Intel 945 chipset limitation, addressable memory will be (4GB - I/O space) ~ 3.2GB
