Single vs dual channel RAM in a laptop

I have a new Dell Vostro 5590 i7 10510U laptop with 8GB DDR4 RAM 2666 Mhz and a NVidia MX250 GPU with 2GB. Win10 Pro. NVMe SSD.

The RAM is running in single channel currently. There is an available RAM slot that can be used to increase RAM. If I add another 8GB “stick’’ of DDR4 2666 MHz RAM (to total 16GB), I presume the RAM will then run in dual channel. Will this make the laptop faster overall?

Not because the laptop is slow, but I want to get the most out of it.

 

dual channel help, searching for RAM info on windows 10

thanks for the reply

I was baffled why cpu z was show me 3200mhz

i am planning to but another stick of 8gb ram for dual channeling:

Crucial 8GB Single DDR4 2400 MT/S (PC4-19200) SR x8 SODIMM 260-Pin Memory - CT8G4SFS824A

is it compatible with dual channeling or am i getting it wrong?

 

RAM not detected

Recently I bought a new 4GB DDR4 RAM stick for my pc with the hope of doubling it, previously I had one 4GB stick. I bought the same brand same model RAM (Crucial Basics 4GB DDR4 RAM, model number: CB4GU2666). When I installed it into the other memory slot of the motherboard (Gigabyte GA-A320M-S2H, rev 2.0, has two memory slots, dual-channel configuration) and tried to boot up, it disappointed me. It didn't boot up. But the fans (CPU fan, power supply fan, and the cabinet fan) were moving.

Firstly I thought that the RAM is faulty, but it isn't. When I replaced the old RAM and put it into that slot (slot 2), it finely boots up. So the new RAM is okay.

Case 1: Any RAM (one at a time) in slot 1, the system does not boot up.

Case 2: Any RAM (one at a time) in slot 2, the system boots up and works fine.

Case 3: Putting the two RAMs in both slots i.e. the new into slot 1 and the old into slot 2 or the new into slot 2 and the old into slot 1, the system doesn't boot up. The same happens as case 1. It seems strange to me! If the slot 1 is not detecting the RAM, the system ought to boot up as the slot 2 works fine. The slot 2 not only denies to detect RAM but also preventing to boot up (as another slot has a RAM) whenever I put a RAM into it.

Please suggest what I should do
