Available PC2-5300 memory from other manufacturers

Manufacturer Partnumber Description Tested on model
Crucial CT2KIT12864AC667 2x1 GB R60e (0657-3LG1)
Crucial CT25664AC667 2 GB
Crucial CT2KIT6464AC667 2x512 MB
Crucial CT12864AC667 1 GB
Crucial CT6464AC667 512 MB
Crucial Rendition RM12864AC6674 1 GB T60 (2007-49G)
G.Skill F2-5400PHU1-1GBSA 1 GB T60p (2007-93G2)
G.Skill F2-5300CL5S-2GBSA3 2 GB

  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
