Tech noob seeks help, 4x8Gb vs 2x16GB RAM

It is only dual channel anyways, so they would perform the same. So i would do 2x16, that way you can add extras later on.

 

But make sure to get the right speeds:

It supports up to 2 SODIMMs of DDR4-2666 RAM, or up to 4 DDR4-2400 sticks.

 

as mentioned above, we’d need to operate at 2400 MHz to support all four slots—but at least upgrades are relatively simple should users find themselves motivated.

Hello everyone, so I'm a bit of a tech noob, but quick to learn and understand.

 

I need help figuring out what would be the best way to go regardless of budget for a gaming MSI laptop I have recently purchased to replace my 8 year old Acer. 

 

The laptop has 4 slots for RAM. 

 

Here's a link, I don't understand half of the stuff there.

So would I do better with 4x8GB or 2x16gb? Should I look for even a larger upgrade in the future like 4X16GB? Is that even worth it?

Generally its easier on the CPU IMC to run a 2x configuration instead of a 4x configuration.

Yeah, as my tech literate friends have said, functionally it makes zero difference however 2 X 16 is generally easier on the CPU and gives a future upgrade path (though nobody really needs 64GB in a laptop anyway).

I'd go 2x16 just to keep slots open for possible future upgrade.

 

Should be no practical difference in performance or loading because 8GB modules are almost always single rank, and 16GB modules are most probably dual rank. So loading per channel is same in that sense.

I would go 2 X 16, every time.

 

I still have nightmares about finding the bad single dimm out of 6 on my old x58 system, and getting them too a stable overclock.

Special thanks to you for finding that, I would've bought 2666 for all slots!

I wouldn't matter, the 2666Mhz would downclock to 2400Mhz.
