Max Memory on Dell Inspiron 15 (3521) Touch

Jump to solution

So, I have purchased a Dell Inspiron 15 (3521) touch from Amazon.com for my kids to use.    It's listed specifically as model:   i15RV-6144BLK
http://www.amazon.com/gp/product/B00CRGJKT2/ref=oh_details_o00_s00_i00?ie=UTF8&psc=1

A chat will Dell has indicated that the max memory that this unit will support is 8GB via 2 x 4GB DIMM chips.

Out of the box, the laptop says it has:   

  • Memory (RAM): 4GB, DDR3L, 1 DIMM, 1600MHz
  • 3rd Generation Intel® Core™ i3-3227U processor (3M Cache, 1.9 GHz)

In looking at www.crucial.com it shows that the max memory for this particular laptop is 16GB and the smallest DIMM they offer is 8GB.
http://www.crucial.com/store/listparts.aspx?model=Inspiron%2015%20(3521)&Cat=RAM

The specs on the Crucial RAM are as follows:

DDR3 PC3-12800 • CL=11 • Unbuffered • NON-ECC • DDR3-1600 • 1.35V • 1024Meg x 64 •   •  Part #: CT39...

So, my question to the community is DOES this laptop in fact take up to 16GB of RAM?  A tech chat with Crucial assures me that it does.

My plan is to buy a 4GB DIMM however, as I don't need more than 8GB of RAM and I don't want to replace the RAM that is currently in the computer.   Since Crucial doesn't offer a compatible 4GB DIMM, I plan to use this model from Kingston.  Anybody see any reason it won't work?

To your question,
How much RAM can my computer hold?
Most editions of the Windows 7 and  Windows 8 OS are 64 bit. If you are running Starter or Home Basic, your RAM limit is 8GB. The RAM limit for Home Premium is 16GB. If you are running a 32-bit OS, such as Windows XP, Vista 32 or Windows 7 32-bit edition, you have a limit of 4GB of memory.

As a side note, that's per slot! That means that can be 8gb (4gb per slot) if using a OS 32bit version and up to 16gb (8gb per slot) if 64bit is running on your laptop!

I just last week bought a inspiron 15 3558 touch screen. dell gave me the run around and said it would only hold up to 8gb with the 5th gen i3 5015 u processor. Every other memory manufacturer has said it will hold 16. It indeed holds 16 and works fine as crucial said it would.

I would trust Dell (the company that made the laptop) more than a memory company.  In any case, if Crucial will guarantee that it will accept 16GB... which means that if it doesn't work, they'll refund ALL your money (including shipping)... then I'd give it a shot.

I'm not sure if that Kingston memory will work or not.  According to the Kingston website, the following RAM is compatible with your laptop:

KTD-L3C/4G, KTD-L3CS/4G and KTD-L3CL/4G

FWIW, Kingston also says that your laptop has a max of 8GB.

I also found this Crucial 4GB DIMM on Amazon...

http://www.amazon.com/Crucial-PC3-12800-204-Pin-Notebook-CT51264BF160B/dp/B005LDLV6S/ref=pd_cp_pc_1

It looks to be similar to the Kingston one you linked, but slightly cheaper.

BTW, Dell offers a 4GB DIMM for your laptop for $62.99.  It's more expensive than the one you linked, but they will guarantee that it'll work.

I do trust Dell, which is why I am doing my research because they don't often lead me astray.  I do know that the technology does move fast and sometimes with BIOS updates, or new CPU's/mobo chipsets the systems "CAN" indeed support more than they originally could.   It would not shock me at all that Dell says 8GB and supports 8GB, but it might in fact run just fine with 16GB.

Thanks for the link to the Crucial 4GB DIMM on Amazon.   In the reviews, somebody posted that they put this chip into a 3521 and it worked flawlessly, so that is exactly what I wanted to know.   My plan was to put this laptop on 8GB of RAM and now I know that I can do it.

Be careful - the link posted in the last message won't work - it's DDR-3 memory.  You MUST use DDR3L (low voltage) memory in this system.

That memory will work, DDR3L is simply DDR3 memory that runs at lowered voltages (1.35v).

"The DDR3L (DDR3 Low Voltge) standard is an addendum to the JESD79-3 DDR3 Memory Device Standard specifying low voltage devices. The DDR3L standard is 1.35V and has the label ’’PC3L’’ for its modules."

The crucial memory that was linked to runs at either 1.5v or 1.35v.  

According to the product description:

"CT51264BF160B is a single 4GB DDR3 Notebook module that operates at speeds up to 1600 MT/s and has a CL11 latency. It is dual voltage and can operate at 1.35V or 1.5V. It is Unbuffered and is non-ECC. It conforms to the industry standard SODIMM layout of 204 pins and is compatible with computers that take DDR3 SODIMM memory."
And as stated, one of the reviews was from a person who upgraded the Inspiron 15 (3521) using this exact memory module and reported that it worked flawlessly.
Here is a video from Crucial on the subject:  http://www.youtube.com/watch?v=PZCOLfDQ6NM

Per Dell:

two slots available for memory. Maximum per slot is 8gb.

4gb and 8gb. Yes, you can mix them

8MB 1600MHz DDR3 1600MHz DDR3 non-buffered is the memory that Dell said would work. No point adding a 4MB as they said I don't have to take the existing 4 MB out in order to add a new 8 MB!

On with Dell tech support right now on this.......unimpressed with their tech support thus far.....on hold for 3rd time....gone through 2 (on the 3rd one now).....they kept asking for my laptop number.

The guy just told me that you can only install 8 GB Max (4 GB per slot).

Not impressed with the tech support.....all Phillipinos and their English is not that good. 

Had to give the service tag 3 times and my name 3 times.....what a pain. 

I think the 8GB  would work, but I am still looking to see if anyone has done it successfully. 

Not sure if it just means it COULD crash sometimes or if it means I'm out of luck if I try this.    Wish someone could let me know.  We have a Dell Inspiron 3521 (15").  Came with 4GB and I want to add an 8GB to it for a total of 12GB.

Hi, I am an owner of a Dell Inspiron 15 3521 that is a touchscreen as well. I have upgrade my laptop to a 1TB Hard Drive. Right now, it has 12GB of Memory in it. It is showing all 12GB and it is running Windows 10 Pro. I say that it could support 16GB but I can't confirm this though. I have a 8GB and a 4GB in the machine right now. Same speed for each one of those. I hope this helps you out. The only thing I wish for that I have the original factory partition. When I purchased this laptop, the hard drive was bad and couldn't be saved. So I had a 500GB and then I upgraded to a 750GB and now I am at a 1TB. Good Luck.

To be fair, the 8GB limit is for the 32-bit system, while the 16GB limit is for the 64-bit. I have no idea why the limits are as such, but there it is.
