Hey guys, so Im doing some clean up and have a lot of ram floating around. I have a Lenovo E530 which came with 1600mhz ram (4gig) but I want to max it out to 8gig. Anyways I gathered all I have, each stick is 4gb. Some 1333mhz and a few are 1600mhz.

My initial thought it to just use the fastest however I dont know how important it is to have a 'name brand' and how important it is that the 2 sticks 'match'. As you can see from the picture I laid these out in 4 scenarios that I thought might make sense. Again my assumption is to use the 2 1600mhz ones (upper left) even though they are diff brands and one of the brands Ive never even heard of, but wanted your thoughts. Also have a matching set of Crucial (1333) and matching set of Samsung (1333)

Anyhow I appreciate the help

Could you post a higher resolution picture?

I would use the fastest ram that runs at 1.35v. The lower voltage matters more in a laptop then speed.
 
The Ram modules are as follows


Samsung 4GB 2Rx8 PC3 - 12800S - 11 - 11 - F3
M471B5273DH0-CK0 1213
(PC3-12800, 1600Mhz, 1.5V, CL11, non ECC)

Hynix 4GB 2Rx8 PC3 - 12800S - 11 - 11 - F3
HMT351S6CFR8C-PB N0 AA 1238
(PC3-12800, 1600Mhz, non ECC, Unbuffered, CL11, 1.5V)



(MATCHING SET)
Samsung 4GB 2Rx8 PC3 - 10600S - 09 - 11 - F2
M471B5273CHO-CH9 1052
(PC3-10600, 1333Mhz, non ECC, Unbuffered, CL9, 1.5V, Rank 2)

Samsung 4GB 2Rx8 PC3 - 10600S - 09 - 11 - F2

Kingston KVR 4GB
KVR13333D3SO/4GR
740617181111 1.5V
(from Tiger - PC3-10600, 1333Mhz, CL9, 1.5V, Unbuffered)


Samsung 4GB 2Rx8 PC3 - 10600S - 09 - 11 - F2
M471B5273DH0-CH9 1119
(PC3-10600, 1333Mhz, non ECC, CL9, 1.5V, Rank 2)



(MATCHING SET)
Crucial
CT51264BC1339.M16FMR
4GB DDR - 1333 (PC3 1600) S0DI
(PC3-10600, 1333Mhz, CL9, 1.5V)

Crucial
CT51264BC1339.M16FMR
4GB DDR - 1333 (PC3 1600) S0DI
(PC3-10600, 1333Mhz, CL9, 1.5V)
 
The quick version is that all of them look to be unbuffered, non ecc, and at 1.5V

2 are at 1600Mhz, the other 6 are at 1333Mhz
All of the 1333Mhz look to be CL9 where the 1600Mhz sticks are CL11


With that said, going back to my original question, is it important to have 'matching' sticks? Also what does 'Rank 2' mean? Also on the Samsung do the #s after 10600S mean something (ie 10600S - 09 - 11 - F2). I assume the 09 is CL9 but what about the 11 and F2

Thanks!

So they are basically all the same.

is it important to have 'matching' sticks?

Not really. Maybe if you are highly overclocking your IMC.
 
So in that case do I stick with the 2 sticks at 1600Mhz? Or would the CAS of 9 vs 11 be more critical? Sorry I know these are newb questions but I appreciate
