Lenovo Y510P memory upgrade

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.

Re: Lenovo Y510P memory upgrade

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).

Re: Lenovo Y510P memory upgrade

Hello, for my mem upgrade i`ve bought from here

 i choose this one  :

Crucial 16GB Kit (2 x 8GB) DDR3L-1600 SODIMM


  • CT2KIT102464BF160B
  • Configuration ID: CT4416139

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.
