This same thing happened to me. I was lied to in the online chat that it accepted 4X4GB and I would later be able to upgrade from 8GB to 16GB, then a year later when I went to upgrade I found out I cannot. I would have bought the 3D version had they told me that was the case, but now I am just stuck with a computer I cannot add ram to.
The notebooks with 2 DIMM slots CAN use up to 16GB RAM. 2x8GB 1333 SO-DIMM DDR3.
There have been numerous reports in this forum that substantiate this.
both are crucial but give different values its very confusing any help would be appreciated
Hi every one. I know that this post is pretty old, but it's been so useful for me that I want to post my experience on upgrading from 8 GB to 16 GB. I own a DELL XPS 17 (L702X / P09E002) with Windows Ultimate 64, 500 BG HDD (7200 rpm). Graphics card is a NVidia GeForce GT 550M, processor is i7-2630QM. Display resolution is 1920 x 1080.
After googling for a couple of weeks I opened the bottom door and discovered 2 DIMM slots with 4 GB each one. So I decided to try and buy a Corsair Vengeance 16 GB kit (2 x 8GB) with part number: CMSX16Gx3M2B1600C9. I bought it from amazon
PC boots perfectly and next step is to add a SSD drive and transfer windows to that drive.
--- UPDATE ---
Finally I bought 1 512 GB SSD Samsung PRO and cloned the OS (automagically because it clones itself during execution) and after a couple of weeks I decided to add a second SSD (256 GB this time). So I have a 5 years old laptop that now is a top-notch laptop.
Hope this helps others.
I purchased one 8gb chip and now have 12g of memory showing. Also 120gb ssd drive from Kingston; the clone software worked perfectly and quickly.
