I am trying to upgrade my RAM of my HP G62-b51SE and found that the stock RAM type is DDR3 PC3-10600S.

I am trying to find the difference between that (PC3-10600S) and PC3-10600.

Following on from Grace's answer, this link What's the difference between DDR3 1333 MHz PC3-10600S and DDR3 1333 MHz PC3-10600 states:

To answer you actual question correctly. The "S" as in DDR3 10600S for example stands for SO-DIMM which is the size of RAM for Laptops. If you had desktop memory the same RAM would say DDR3 10600. Crucial and other companies have a way of not listing the RAM speed with the "S' because in the title of the RAM you are purchasing it says "SO-DIM' but when you get your RAM it will have the "S" on it if you are buying for a laptop.

S stands for SODIMM, meaning the RAM is for laptop.

    +1 - For the _actual_ correct answer..! However, if you could edit your link to provide some backup to your statement (a link and a summary of that link), that would be great. – Greenonline Apr 20 '16 at 03:02

Google searches for 598859-001 and 598856-001 as shown as the replacement parts in your picture result in memory of type pc3-10600. I think its just a confusing label on your modules.

  • Even if 10600S is the actual stock type, I'm guessing there is no practical difference. – Louis Waweru Dec 18 '12 at 05:56
  • PC3-10600S would usually indicate registered, synchronous memory. See, for example, [here](http://www.pinterest.com/pin/479633429036823136/) or [here](http://www.amazon.com/HYNIX-Laptop-Memory-HMT325S6BFR8C-H9-PC3-10600S/dp/1254875778). – David Schwartz Jun 30 '14 at 06:45
