If Crucial recommends it, it should work...

Can't guarantee the RAM will run in Dual Channel Mode because the new 8 GB module won't be exactly identical to the existing 8 GB module. But 16 GB running Single Channel Mode should still be faster than the 12 GB you have now which is running Single Channel Mode because the two modules aren't even the same size.

You can check the Channel Mode on the Memory tab (= "Channel #") in CPU-Z (free).

Always power off, unplug, and press/hold power button on front of PC for ~15 sec before working inside the case. Consult the Service Manual for more info about removing/installing RAM. And save the 4 GB module that you remove, just in case...

Post back and let us know when you have 16 GB of RAM running. And congrats - you passed the math test!  😋

Are you asking how much RAM you can add? Or what brand to buy...?

And it would help if you tell us how much RAM you have now...

Here are the specs for this model:

So you could use up to 2x 8GB RAM modules, maximum. Many peeps around here buy RAM for Dell PCs from crucial.com because they guarantee it works if they recommended it for your specific PC model.

And you want to use an identically matched pair to allow the RAM to work in Dual Channel Mode. Mismatched modules will only work in slower, less-efficient Single Channel Mode.

Re-read my previous post... 😉

You have 12 GB (1x 4 GB + 1x 8 GB) and one of those two will have to be replaced because you only have 2 DIMM slots, so do the math...
