I'm thinking about buying Lenovo Y700-15 (standard version i7, 4gb ram, 1tb hdd) and i have three questions about this notebook:
1) I want to upgrade ram memory and the question is DDR4 2400MHz will be working on this laptop with 100% performance? (Kingston HyperX Impact SO-DIMM 2x8GB 2400MHz)
2) I would like to install SSD drive on M.2 port .This port will be working with NVMe protocol? (Samsung SM961 256GB)
3) Will I void warrancy when I made this upgrades?
Buying laptop on weak configuration and upgrading is cheaper than buying in ready configuration and I will have better components (if somebody would like to know why I would like to upgrade weak configuration).

Hi there. Here is the Hardware Maintenance manual link -
1) From what I read, there are 2 different models. 15ACZ supports only upto DDR3L 1600MHz whereas the 15ISK supports upto DDR4 2133 MHz. Please check which model are you buying.
2) From the list of SSDs, I think the relevant one for you would be - SSD, Samsung MZVLV256HCHP 256GB M.2 PCIE SSD
EDIT - You will need to confirm from Support that the laptop you are buying has an M.2 port. I have the 14" model and I can open to check if that model has an M.2
3) In my experience, as long as you do not damage any components while making the replacement and do not leave any visible marks of tampering (like broken/chipped back case), your warranty will remain intact. If you are in the US, I have seen Lenovo honoring their warranty quite well, even when I put in an SSD.
Let me know if that answered your question. Thanks.

1) I'm buying y700-15isk with ddr4. I'm asking about 2400MHz becouse some people in internet wrote they bought 2400mhz and it works perfectly in this notebook, So now I dont know - motherboard works with 2400mhz or 2400mhz is underclocked to 2133mhz? (on same pages there are configurations of this laptop with ddr4 2400Mhz)
2) Yes this laptop has M.2 port but i'm not sure it will work with NMVe protocol. Fast ssd is very important for me because I'm working on big files.

Well, you seem to know your stuff. So, only going by the manual my assumption would be that the RAM is downclocked to 2133MHz. I dont think there is any XMP support in there. There should be negligible difference between 2133 and 2400.
Also, again from the manual seems like the Samsung PM951 (NVMe) is supported. I cannot confirm this about SM951.
This is mostly a voluteer forum, so hopefully someone who owns this laptop can drop by and provide more accurate information.
