Single vs dual channel RAM in a laptop

The RAM can bottleneck the CPU when benchmark testing.
In real world testing you won't notice the difference.
You would need to push the computer to extremes.

Most end users do not overclock laptops.
So for the typical laptop you won't notice the difference again when using single as compared to dual channel.

When adding or replacing RAM these are important:
a) Use RAM that is displayed on the computer or motherboard manufacturers Qualified Vendor List (QVL)
b) Always purchase in pairs with matching SKU (so that there are no compatibility problems)
c) Consider RAM manufacturers offering lifetime warranty

When adding or replacing RAM consider the pricing for two 8GB versus one 16 GB.
If its a minor difference go with the two 8 GB.

One other factor to consider is having four DIMM with 2 RAM modules.
Typically adding only one RAM module converts dual channel into single channel.
The single and dual channel refer to the function of the motherboard.
In the owners manual it may indicate which DIMM to use when using one versus two RAM modules.

Ram Upgrade

My laptop is a HP ProBook 4540s with 4 GB RAM installed. My question is

What is the largest amount of Ram I can upgrade it to? Should I add a 4GB chip or have it removed to install 1 8GB chip?

Is there a large cost difference? I am running the latest version of Windows 10 Pro.
