This is my stock ram and i cant find information on ram type pc3-10600S : – user1907294 Dec 18 '12 at 3:26
maybe it is meant to mean plural. – barlop Dec 18 '12 at 5:25
Maybe the S refers to Stock. – deed02392 Jan 23 '14 at 11:21
Where did you see "pc3-10600s" exactly? – David Schwartz Jun 30 '14 at 6:43

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 Dec 18 '12 at 5:56
PC3-10600S would usually indicate registered, synchronous memory. See, for example, here or here. – David Schwartz Jun 30 '14 at 6:45
