Macbook Pro Memory compatibility

[unkinkedash]

Hey everyone, I'm new here and I really considering upgrade my macbook pro mid 2012 A1278 memory. But I'm having a hard time trying to find a compatible memory. I recently found one with these specifications:

• Brand: Kingston
• Model: KVR16LS11/8
• Memory modules: 1X 8GB
• Capacity: 8 GB
• Type of memory: SDRAM
• Memory's technology: DDR3 SDRAM
• Memory's format: SODIMM
• Speed/Frequency: 1600 MHz
• 204-pin SODIMM
• 204 pins
• Tranmission: 8GB/s
• latency: 11
• (1.28V ~ 1.45V) e 1.5V (1.425V ~ 1.575V)

So, is this memory compatible with my mac? I was willing to remove one of the slots of 2GB and replace it with this one and leave the other slot with the other 2GB. Also change the hdd to an ssd.
Thanks a lot!

It should be.
The RAM you need should be:
PC3-12800 DDR3L
1600Mhz
SDRAM SO-DIMM (204 Pin)

As long as these things are in order the RAM fits. The machine can support up to 16GB

To add to @Schranke's comment, it also needs to be 1.35V. Which yours is.

both 1.5V and 1.35V works fine

Apple genuine memory are 1.5V Elpida or SK Hynix

Is there any problem to maintain one slot with 2GB and the other slot with a 8GB? Making the macbook with 10GB total

To my knowledge no, but I have newer done it myself.
There is a little different opinions around the web but most of them seems to agree to try and then remove a stick if there are problems.

I have the Crucial 16GB (2 x 8GB) DDR3L 1600

It works great

It’ll probably work, but with a minor performance penalty. This is because the machine will no longer be able to operate in dual channel mode over the entire memory capacity as, in your case, 6gb of your memory will be provided by just one module in isolation. I’m not sure whether the machine will drop back to single channel mode or stay in dual channel mode (but effectively only for the first 4gb). The performance penalty of dropping back to single channel mode is often felt the most if you’re using integrated graphics.

Not a problem.

I have 4GB + 8GB in mine.
