Question Upgrade RAM for my laptop

[JCMaxxwell]

System configuration:
Intel core i3-8145u
Intel UHD Graphics 620 iGPU
8 GB RAM (PC4-19200 1.2V 2400MHz SODIMM 260 pin)
System board: HP 85EF
Storage: 250GB Samsung 970 evo Plus (PCIe3)+ 1TB HDD 5400RPM SATA 6GB/s

I want to upgrade my laptop RAM.

It has 2 DDR4 2400MHz SODIMM slot.

Now I have a 8GB stick installed in it.

I have choiced some RAM sticks, someone please suggest me which will be the best?

1. Corsair-Vengeance CMSX8GX4M1A2400C16

2. G-SKILL-Ripjaws F4-2400C16S-8GRS

3. Crucial-CT8G4SFS824A



If I install a new 16GB stick with the existing 8GB one then will it work as dual channel 2400MHz?



And another query, I have an Intel UHD Graphics 620 Integrated Graphics, currently it have 4GB shared GPU Memory. If i install another 8 or 16GB stick then how much shared GPU Memory will it have? Will it increase GPU performance?

That's the motherboard.

What is the full and complete model name of the laptop itself?

How did you happen to choose those 3 particular RAM selections?

Actually I used these ram brands previously, and impressed with all of them.
The system model nane is HP 15s-du0094tu

Please recommend me which one of the 3 (or anything other than those) will be best for this mentioned laptop?

And also, please tell me the 16gb+8gb combination and UHD 620 iGPU factor?

Above is the link to Crucial's scanner and what it says about your specific HP.

I'd go with what it says rather than wonder if some other RAM would work. The scanner is highly accurate if not absolutely infallible.

Order from Crucial direct or maybe try to find that exact model number elsewhere.

Best advice is to buy all new rather than add new to existing. You will be taking some incompatibility/performance/no happy ending risk if you do otherwise.

I studied the specs of the crucial and gskill rams thoroughly and found they are exactly equivalent, and matches my presently installed ram.
What will be better one the crucial or the gskill if have exact match?
The gskill ram is cheaper by about INR 1000 or $13. Should I take the gskill one?

Also, please tell me, if I install a 16gb 2400mhz with my present 8gb ddr4 2400, will it work as dual channel? And also the uhd 620 factor please?

I would not take the Gskill.

Despite "specs", you cannot tell if they are "exactly equivalent".

You would be taking a risk. How much no one can tell you. If you want to take the risk, go ahead. May or may not work out for you.

I would buy exactly what the Crucial scanner leads to. All new. I would not add new to old. If you want to take the risk, go ahead.

Two new sticks would certainly work as dual channel.

I have no idea about your other questions.
