Looks very nice, sturdy, and easy to handle. It came up as "compatible" for my Dell Inspiron 15-3521 so, I purchased it. The laptop worked, and all the heavy apps like MS Office 2010 ran quickly, and flawlessly. The only problem was that this particular module made the screen flicker, to the point of where I had to chase after the buttons and links all over the screen with the cursor in order to click it. I took out 1 card and ran it on 8GB and the screen didn't flicker as much, but it still flickered and made my eyes go funny. I put the original modules back in, and solved the problem... I updated the BIOS and updated the video driver, and so on, but it was the new set of memory causing the flicker. I'm not sure if this particular batch was defective, but, it's safe to assume that these are not compatible with my Dell Inspiron since I tested both of them one at a time. Therefore, I asked for an exchange for the 12800Mhz module which matches the original.
Dell Inspiron 15-3521 has a shared video memory, which I think that's where the problem was.
So I used the online hardware checker tool to get an extra 16g memory. Did the deed and went with what was suggested, and was shipped out 16g of PC3-14200 (ct102464bf186d) to go along with my current 16g of HyperX pnp PC3-12800H
So I eagerly plugged in, and no boot. Aftersome checks I see that the voltage for the Crucial memory is 1.35v and my HyperX is 1.5. Also, the speeds are not the same, seems the Crucial memory runs faster.
So I guess the scanning tool has mismatched me memory that won't be compatable together?
If that is the case, can I underclock or overclock one set to get them working together?

The Crucial Memory Upgrade Advisor lists
CT6287719 - 8GB DDR3 PC3-12800 Unbuffered NON-ECC 1.35V 1024Meg x 64
as the correct upgrade for an HP 15 Series 15-f039wm, which has only one memory slot.
However, the HP forum dude/guru/guruette says that the installed 4 GB SODIMM module
ADATA AM1L16BC4R1-B1PS 4GB 1RX8 PC3L-12800S-11 DDR3L 1600 CL11
HPSPARE 691740-001 DC1470
is all she wrote... something about the Intel Bay Trail-M (Celeron) processor can only access 4 GB.
So, who's right? Do I upgrade this Windows 8.1 64-bit machine with a CT6287719, or not?
