Hello Dell community,
I use my inspiron 7520 for nearly 3 years now and i've decided that it's time for an upgrade..Since i love this laptop so much and it has been more than useful to me, i want to replace my hard drive and add some ram..But i don't know if it's possible. So my question is,can i upgrade my 8gb ram to 16 or 12?
Thanks in advance!
Solved! Go to Solution.
The 7520 supports a maximum of 8GB memory.
You could however, replace the HDD with SSD.

Officially on the record, the 7520 might only support 8GB of memory, but in reality, it can support 16GB, too. I had a 7520 for a little over 3 years, and went through multiple BIOS upgrades with it. All the while the 16GB (2x8GB) I used with it worked perfectly fine. For the record, I used the following DDR3 SO-DIMMs, but probably many others would work, too.
Regarding replacing the hard drive, yes, it is no problem whatsoever (my 7520 had multiple hard drive upgrades). As DELL-Rishi has indicated, you might consider an upgrade to an SSD--it makes a HUGE difference especially if used for the system drive.
Since larger capacity laptop hard drives (like 2TB) are still significantly cheaper than equivalent capacity SSDs, there is an interesting solution for the 7520 (and many other machines, too). If you don't use the optical drive, you can get a replacement drive caddy that will fit a 2.5" laptop form factor drive into the optical bay slot. Of course, you still have the regular drive bay, too. In fact, that was the last configuration I had for my 7520 before it failed. I had a 500GB SSD in a drive caddy in the optical drive bay, and used that as the boot/system drive. And then in the regular drive bay, I had a 2TB regular drive for storage. It was wonderful and blazingly fast--it breathed a whole new life into the machine. Indeed, I would still be using it today if the motherboard had not developed a short several months later.
Note that if you do want to consider replacing the optical drive with a drive caddy for a 2.5" drive, you should be careful of the size you order. These caddies come in slightly different heights that essentially look identical in online pictures, but that will be obviously wrong when you try to fit it. In the case of the 7520, it needs a 12.7mm high caddy. I ordered the following for <$4, and it worked wonderfully.
Good luck with your 7520, and here's to hoping you don't develop an infamous mobo short like so many others! If you have any further questions, just PM me. Wait, can we actually PM on this board?
