I have a question about the RAM in the x230. I bought the base 4gb of RAM with the intention of upgrading it myself later.
The stock RAM inside is a Samsung model with this serial:
However, I cannot find this model RAM to put in another identical stick into the open slot. The closest model available is:
Do you think these two sticks would be compatible? Did anyone else try a different type/model/amount of RAM? My gut feeling is that 8Gb of RAM would be great, and that 16Gb would be overkill.
The other option is just to shell out a few more bucks and buy two pieces of matching RAM. I am considering Cruicals and Cosair Vengence RAM.
Let me know what you guys think,

if you were to order from Lenovo: http://shop.lenovo.com/SEUILibrary/controller/e/web/LenovoPortal/en_US/catalog.workflow:item.detail?...
you'd probably get Samsung, Hynix or Nanya, from my experience. most recently, i got Hynix. price may be higher than other places, though.
from what i've read, Crucial is good quality, but Corsair may be hit or miss.

I just wanted to add a bit more to what sarbin had offered. You can get the SO-DIMM he suggested in 2,4,8GB and all are supported for X230 and will work with your current memory installed. These are Lenovo bought Memory is why I can say they will work any third party memory is not guaranteed to work.
Here is a link to the Psref for X230:
This is what is says about memory:
7 / PC3-12800 1600MHz DDR3, non-parity,
dual-channel capable, two 204-pin SO-DIMM sockets
If you have any other questions please post back and we will be more then happy to help in anyway we can.

I guess my question didn't come through exactly. I want to leave the stock Samsung stick in and put a second identical stick in the second slot. However, I can't find that specific model SO-DIMM being sold elsewhere. As an example this is the closet match I could find, but the serials are slightly different. My understanding is that if its the same manufacturer with the same voltage and latency values then its okay but its always best to have matching RAM right?
I was wondering whether anyone used this with the stock SO-DIMM they received. Or if others had a suggestion of better configuration.

you were understood, jahganja.
and you are correct that as long as the dimms match specs, you should be ok to gain the most benefit afforded by "matched" dimms. my point, and i apologize for not making it well, is that if you want dimms "matched" as closely as possible, you probably have to buy them together.
if you order a 4gb dimm from lenovo, i'd bet you'll get one that performs just fine paired with your existing dimm, but you'll get samsung, hynix or nanya, depending on what's in their shipping supply. i'm not at all surprised that the samsung dimm on samsung's site carries a slightly different part number, but again, if the specs match and it's high quality ram, i don't think you'll have any issues.

I think my answer was confusing but here lets see if we can sort this out. What it comes down to is what you stated voltage and latency, if you check these between two different memory sticks and they are the same you should be fine (if you plan on not trying to overclock). What I was talking about is that if the stock memory your X230 came with should work with any brand lenovo memory they sell you from Lenovo.com that is compatible with your computer which I linked.
As I was writing this Sarbin replied and I would have to agree as we are both saying the same thing lol. If you are still confused or would like anymore help please post back and we will be more then happy to help you.

Oh, now I get you guys. I thought you meant when you originally order the computer the RAM that's available. I didn't even know you could buy more RAM from Lenovo.com
Yup, I get it. I guess I'll gamble just a little and try them get them as close as possible. None of the RAM sold on Lenovo.com seems to match my SO-DIMM... and its quite expensive. If it ends up being compatible I'll post here and let everyone know what I did.

I 've a x230 with 4go of ram, if I buy 8 go, I'll have 12go, will I have dual channels?
dual channel asynchronous, i believe, vs synchronous.
i've seen reviews that purport a 5-8% increase in memory access efficiency in synchronous mode, but it likely doesn't make a noticeable impact on the average user experience.
