Max memory on samsung series 9 NP900X4D-A05US

hi im planning to buy this lap top,it comes with 4gb ram installed i want to ad 4gb more,there is no information anywhere on the internet does this laptop comes with one slot or two slots,i allready search on samsung site and talk two times with samsung represenatives but they are all usless since samsung site is not updated with this model,i m using chronos 7 and when i open back cover i can see only one slot but computer reads 8gb so i guess its hidden someware under motherboard is this same thing with series 9?thanks

 

I has two DDR3 SoDIMM slots and can be upgraded to 16GB. See the pic below of the inside of the NP900X4B. The layout hasn't changed much in the X4C or X4D.

 

thanks for quick answer,both slots are reachable after i open back cover or just one slot?

 

You have to remove 10 small screws on the bottom of the machine and take off the whole bottom sheet metal plate. It isn't that hard. If you plan to upgrade the mSATA drive, do both at the same time.

 

cool so both slots are reachable,ok so i can use intel ssd 2.5 instead of stock ssd?
I dont see on pic where is hard drive,is it under black cover by the battery?

please dont tell me that i cant use this in series 9 http://www.newegg.com/Product/Product.aspx?Item=N82E16820167093

 

There is a photo of the inside of my X4C in my review. The X4D is the same internally. The SSD is to the left of the fan.

You cannot fit a 2.5" SSD into the X4C. You need an mSATA SSD. See my photo here which shows the difference in size.

Ok got it,will the device manager read which ssd is installed on series 9 laptop in the store? Im planning to buy series 9 and i dont want sandisk ssd,samsung repersenative saying its samsung ssd but i dont trust them want to check by myself, i mean device manager will read and gives info for msata type or brand of ssd like any other drive right?

 

Device Manager will give the SSD model number which you may need to Google for more details.

Ok,in case i need to remove sandisk ssd and install msata ssd is it just plug and play like with installing regular ssd or i need some cables adapters etc, and is it procedure the same like i had with series 7 disabling uefi,fast boot and i dont remember what else in order to install fresh win 8?

 

Read this thread and this thread.

Windows 8 makes the process more complicated. Do you have a Windows 8 disc?

John

 

Yes i have win 8 disc,but there is no optical drive in this model

 

It's useful to have a USB optical drive available and they aren't expensive (<$25). You don't need a Samsung branded drive.

We know that a clean install from a disc will work with Secure Boot and UEFI disabled. Other ways may work but tend to create more hassle.

John

 

Samsung brand is a hassle, can that be done and connected over usb external optical bay if such a thing exist

 

Any of the drives here, except the CD-ROM, should work. The hassle is the same with any notebook that does not include an optical drive.

Hi there!
can't believe that true, why're they saying on amazon and elsewhere that max.ram is 4 gb....?
if that's the true, i'll upgrade it asap! )
Can someone please prove to me that's possible with some pics of system properties or something? please
Thanks, brgds!

 

I'm sure someone did test 2 x 8GB in either the X4C or X4D to confirm that the configuration worked, but I'm happy with my 2 x 4GB configuration.

Even if Samsung left out one of the RAM sockets it would work with 1 x 8GB. The only possible obstacle that you might encounter is that when Samsung updated the BIOS a few months ago they deleted support for 1.35V RAM so it would be prudent to use 1.5V modules.
