[HELP] ASUS S451LN Laptop Memory module

[sas28ke]

Hi All,

I have an ASUS S451LN laptop that has 4GB RAM and additional memory slot with 1.5V marking. Just wanna know what is the maximum frequency of RAM that I can throw in that extra slot. Is 1866 MHz 4GB RAM stick possible?

Your best bet to purchase ram is to go through the ram manufacturer's compatibility tool, most have them.
From experience I will tell you that Crucial or Kingston will be you best bets for compatible laptop memory but here are a few links to get you started

Last, I will recommend replacing both sticks with a "kit" of ram which will ensure compatibility.

Thanks C12Friedman!

But my laptop only has 1 accessible memory slot. The other one is onboard i guess.
