L340 ram upgrade 16gb 2666

2020-07-29, 21:15 PM

Hi, I own a L340 I15H  with 8gb ram, I updated ram with a 16Gb Crucial 2666, but it only works at 2400, the original ram (8gb) is 2666 too, and was working at 2400 too. Is there any way to modify the CL from 18 to 19?? I have not found that option in BIOS, or this is a motherboard limitation with a specific purpose?? 


Thansk in advance

Hi necktru,




Checking with the product specifications sheet shows:


16GB max offering / 2400MHz DDR4, optional 4GB memory soldered to systemboard, one DDR4 SO-DIMM socket


As it does support higher frequencies like 2666, memory controller does buffer this to 2400MHz to help synchronize memory interaction.


This includes CL regulations to make both rams work together which is automatically set by defaults.


I hope this helps answer your query.

The RAM  runs at the speed determined by the CPU and chipset, in this case, 2400  Faster RAM will just clock down.
