I was looking to upgrade my memory on my laptop. It came with 1-2gb stick and 1-4GB stick for a total of 6GB.
I used Speccy to look at the Ram and I learned something, You can run 1.5volt ram and 1.35volt ram together in the same laptop! The 4GB is 1.35volts Kingston TSB16D3LS1KBG/4g and the 2GB is 1.5volts Kingston TSB1600D3S11ELD2g. I want to upgrade to at least 8GB so I guess I am looking for another TSB16D3LS1KBG/4g stick to match up or do I need to max it out to two 8GB=16GB?

The Toshiba Satellite C55-A5310 laptop supports a maximum of 16 GB(8 GB X 2) of RAM.
It uses 204-pin, 1.5 volt, CL=11, Unbuffered, Non-ECC, DDR3 modules.

DDR3L modules run at 1.35 volts, so it's my guess that's what your 4 GB module is.
If you Google search that model number, you should be able to find it on Amazon or elsewhere for sale.

I seriously doubt you'll get any added speed benefit from using 16 GB(8 GB X 2) over 8 GB(4 GB X 2).

Thank you flavallee, I found another 4GB stick for $16 and ordered it. The 8GB sticks were about $40.I was just surprised that the 2gb was 1.5volt, didn't think you could mix them. It has windows 8.1 on it now and I may put windows 10 on it later. I maxed out my desktops memory because I found them cheap and they don't make them anymore. I wondered why the Kingston memory started with a TSB instead of a K and from what I read TSB is system-specific memory for Kingston. The next upgrade for my laptop is an SSD, the hard drive in it tested at a pitiful 84 MB/s, the HD on my desktop was 118MB/s my new SSD on my P43T is 294MB/s.

You're welcome.
Good luck with the new 4 GB module. (y)

I read the marketing specs on your model laptop, and it did come with mismatched DDR3-1600 modules (4 GB + 2 GB).
I never understood why manufacturers do this. :confused:

According to its marketing specs, yours has this Intel processor, so spending extra money for 16 GB would be futile.
8 GB is plenty.
