Laptop RAM Upgrade - 4 GB soldered + one empty slot - Dual Channel

Hello

I have Lenovo V130 - 15IKB laptop

Intl Core i3 - 8130 Processor
1 TB HDD
1 WD 500 GB SSD installed in m.2 slot
Windows 10 installed on WD m.2 slot SSD

4 GB DDR4 RAM Already soldered by manufacturer, one Slot it empty, as per Lenovo the laptop supports maximum 12 GB RAM

Now i want to add more RAM, so i only have empty slot so my question is

How much should i add 4 GB or 8 GB ?
if I use 8 GB will i loose Dual Channle mode , is it right ?

is it ok to put another 8 GB with current 4 GB and make it 12 GB, but i think i will loose dual channle support,
But i heard that there is a intel technology as Flex Mode Ram, where, half of 8 GB will run in dual channle and other remaining of that 8 gb will run single channle

Please suggest what should i do, 4 GB or 8 GB

also on many of the site the RAM description showing as Single Channle, what does that mean, will it only work with Single Channle or dual channle see image

Hello experts please help me

Forget about dual channel ram, it does not matter for intel processors & even in ryzen processors it matters most for vega integrated graphics.

First of all, there's no such thing as "dual-channel memory." I want to get that cleared-up early. Memory channeling exists at the platform level, so a dual-channel chipset or IMC (Integrated Memory Controller, as in modern CPUs) may exist, but the memory itself does not have a special bit or chip that controls this. It is up to the motherboard and supporting platform to offer multiple channels.

There are only single rank & dual rank ram modules but even those do not usually matter for latest gen processors.

so if i add 8 gb more and make it 4 gb + 8 gb , will it cause any hardware or compability issue ?

Will it work in dual channle or single channle .

what is the best thing to do, 4 +4 or 4 + 8 or just use 4 gb

For intel it does not matter whether you run 4, 4+4, 4+8 or 8+8(if supported by laptop). For dual channel mode you need at least same capacity ram in both slots & even then it is not guaranteed as some ram models don't work well with each other especially if they are from different manufacturers. For laptops the min I have seen supported in recent laptops is 12gb ram.

So dual channel is only for desktop.. and that too if RAM bought in A kit

No, if 8gb is enough for your usage then you can buy a 4gb ram with same frequency & it will most likely work in dual channel mode with your existing 4gb laptop ram. Same for desktop, no need to buy kit if you can buy two of same model ram.
