I upgraded my NP900X4C-A03US a few days ago to 16GB as well. I found some Mushkin RAM that runs at 1.28V instead of the 1.5V that the Samsung-manufactured RAM that came with the computer does -- the JEDEC timing parameters are the same. The lower operating voltage will help with battery life:

How's the Mushkin RAM working out for you T.? I have the np900x4c-a01us and thinking of getting the Mushkin 16gb ram set or the Komputer set Will Stone's recommended on Amazon.
I wouldn't get the Komputer set on Amazon. Had it installed and running but then it crapped out a week later. Ordering Mushkin RAM recommended by T... as it matches all specs of the RAM that came with the computer.
I just ordered 2 8Gb crucial sticks to try this very thing. Have you ever thought about swapping in an i7-3520M CPU? According to cpu-world they are compatible. Has anyone tried this? It would be awesome to go from 1.9 Ghz to 2.9 Ghz with this upgrade.
Hi Steve, i would love to know if you were successful. I love this laptop and dont feel the need to spend 1500 on another latpop that i might not love as much..so being able to upgrade the cpu would be awesome as I have already upgraded to 1TB SSD & 16GB RAM..with an i7 and the other upgrades it would get a renewal of life for another 2+ yrs..
Do you think the ram could be upgraded on the 13.3" version as well?
ReplyDeleteUnfortunately it can't be... unless you have the pre-2012 model.
DeleteHere's my investigation of the 13":

Wait, there's a pre-2012 13" model that might take 16GB? Which? X3A will not post with 16GB AFAICT.

Great idea! Any way you could do a run-down test & post the new battery usage with the 1.28V RAM?

Further note: the X3A will work at 16GB if you have at least one of these modules. (Evidently a power/posting issue).

ReplyDeletethanks for the feedback. i've used komputer 16gB on 3 machines and they've worked flawlessly for me. guess it's just luck of the draw
DeleteOne simple question,
ReplyDeleteThe AES-NI instructions are working for you? I can't get it working in Truecrypt or detected by CPU-Z..
it's supposed to be supported by tc7...
Deleteit's supposed to be supported by tc7...
DeleteEven Intel Processor ID Utility don't show support for AES in mine.
DeleteNP900X4D with i5 3317U here.
Looks like a BIOS issue, no updates till now...
For the record, in NP900X4D Samsung changed aluminium black for magnesium silver, RAM for 1 x 4gb A-DATA 1600 (and blocked purposely AES-NI???)
Hello Will,
ReplyDeleteDo you think this kit will work on 900X4C?

Many Thanks,
G'day Nelson, I upgraded with this RAM last week along with the Crucial M4 256GB mSata drive and it worked perfectly.

hmm i'd be very surprised if the cpu was removable! lmk if you try it... i was fine with the one it came with!
