I think any DDR4 would work but I bought T-Force Vulcan DDR4 2666 from newegg.
Here's the link.

Yes, I posted about this before. Regardless of what the HMM doc says, that a 16GB stick *can* be used, at least for some 330S models, to get 20GB RAM total. See my post history: https://forums.lenovo.com/t5/forums/recentpostspage/post-type/message/category-id/Community-EN/user-...

A QUICK UPDATE.
I was wondering whether 16GB will be supported of not. Officially , accourding to Lenovo recommendation this laptop supports 4GB(Soldered) + 8GB(Open slot) = 12GB of total memory. But I checked on Crucial offical site what model I would need. The site showed me 16GB would be supported so I ordered one. I put the 16GB in open slot & turned the laptop on. WALLAH...IT WORKS !!! Now I'm getting 4GB + 16GB = 20GB of total memory. I was facing stuttering while playing Gears of war 4 but now the stuttering is gone. The RAM gives enough head room for multitasking also & help to run graphics intensive aplications so easily . But previously I was getting 30GB/s read & write speed from OEM memory , Now it goes down to 20GB/s read & write speed. Although I am not seeing any issue with this speed but It is quite slow than OEM RAM. Anyway 16GB will work on single RAM slot.
