Hello, Lenovo community,
I have been desiring to do a memory upgrade for my Lenovo Y510p, specifically from 8gb to 16gb. I have one question about the memory speed of the 16gb. Crucial gives me two 16gb options, and here are some differences (other than price):
option 1; DDR3 PC3-12800 • CL=11 (1600 MT/s)
option 2: DDR3 PC3-14900 • CL=13 (1866MT/s)
My question is: does the memory speed affect the laptop in any way? I looked across the internet and seem to not find an answer.

There are two parameters which affects RAM speed - frequency and timings. You may get theoretically faster RAM, but with higher timings, they would be only slightly faster. As the result, you may only get around 1 FPS more in game. Also your laptop may not support PC3-14900 CL13 configuration and as result, will downclock memory modules to PC3-12800 CL11 configuration... or won't boot, if memory isn't compatible (please do not buy any Kingston Value - they tend to make issues). Please make sure, that modules which you'll buy are DDR3L (1.35V), as standard DDR3 modules require higher voltage (1.5V).

Hello, for my mem upgrade i`ve bought from here https://www.crucial.com/usa/en/compatible-upgrade-for/Lenovo/ideapad-y510p
i choose this one :Crucial 16GB Kit (2 x 8GB) DDR3L-1600 SODIMM
DDR3 PC3-12800 • CL=11 • UNBUFFERED • NON-ECC • DDR3-1600 • 1.35V • 1024MEG X 64 •
no problems encountered.
teoretically the other one is a more rapid. I don`t think it will be a speed boost in your laptop - maybe if you like to post some synthetic benchmarks to brag - it will help.
I`ve choosen my kit as it was the same speed as my two 4GB modules instaled by lenovo.
