1 RAM bar or 2 RAM bars with two slots?

I wanted to ask if there's a difference in the performance when playing or the "normal" use of a PC if I take only 1 RAM bar with 16 GB for 2 RAM slots or take 2 RAM bars of 8 GB each, or is that all the same?

Because I have a laptop (acer) with 2 RAM slots.

I did not find the right answer on the internet.

Re

There's more performance in dual-channel mode, ie 2 identical RAM modules on 2 slots, as long as the mainboard supports dual channel.

Jo

How do you mean if it supports dual channel, it has 2 slots and just 2 RAM bars are 4gb in there.

Te

2 x 8 GB makes more sense, because then they run in dual channel mode, it does not make a lot of difference, but since 2 bars cost not much more than a corresponding single bar, that makes sense.

He certainly means if the CPU supports dual channel…

OK thanks

Thank you

The CPU has absolutely nothing to do with it!

The motherboard is responsible for this.

And dual-channel is actually the minimum standard. Even my 2005 Pentium4 had 4xDDR1 slots and supported dual-channel.

However, there are still special, or better motherboards that support triple-channel, or even quad-channel support.

This means that the ram slots are divided into 2, 3, or 4 groups, each with its own data bus that allows parallel access. Such a group can consist of a single, or even several ram slots.

Here is an excellent explanatory video:

Well if that is so then I apologize and will tell Intel that the specification for their CPUs are wrong. Example Intel Atom D525 and that you should remove the memory controller from your CPUs.

Of course, these CPUs must support this.

More details can be found here under "Memory specifications" or "Seicherkanäle":

https://ark.intel.com/...-3-40-GHz-

In between, however, is the motherboard with its specific chipset.

And if I understood that correctly (I'm not an expert), the Intel chip set has the "Northbridge" responsible for managing the ram modules.

If the CPU can provide 2 or more memory channels, that does not mean that the motherboard will handle it.

These controllers in the CPU and on the motherboard only need to communicate with each other and establish a compatible working mode.

The more active data channels can be used in parallel, the faster the system gets.

What ever. It is always the one dependent on the other.

To the question itself:

I always try to use Dual Channel. Does not always have a lot to do but nice.

On my old X58 motherboard which uses Triple Chanel I imagine that it means faster than single channel mode.

Ergo: Better 2 x 8GB than 1 x 16 GB

Most motherboards support the "dual channel", which means if 2 RAM bars are used, the performance is better than with 1 RAM bar.

However, the difference is really very small. He is only mess and not noticeable.
