What is memory routing support for ddr4 2666mhz?

Hello,

I was looking for this information on google but I couldn't find anything helpful.

This is something that was advertised for intel z370 chipset, but I don't understand what they mean by memory routing support. Is this some bios setting that if you have memory routing support turned on with the ram speed of 2666mhz, does this make the RAM speed of 2666mhz better than with this setting turned off at 2666mhz?

From marketing slides? Best to ignore that entirely.

It might have something to do with Optane support.

No. What it means is that Z370 will support memory up to 2666mhz by default, without the need to enable XMP profiles or manually configure the memory. Of course, this will be dependent on the motherboard model implementation, other bios settings and what CPU is installed as well.

But typically, when DDR4 was new, only 2133mhz was supported by default. Eventually they started seeing support for 2400mhz and now with Z370 your system might automatically configure the memory to 2666mhz if it has 2666mhz or higher modules installed. This does not mean it cannot run at higher speeds, if you have higher speed memory, but you will have to either enable the XMP profile or manually configure the memory to go higher than 2666mhz.

It will also matter if the module has a JEDEC SPD profile for 2666mhz. If it does not, then it probably won't default to that speed and will still need to be done either manually or by XMP.

It has nothing to do with anything running better or faster, except by default.

Is that all they mean, I wonder why it is called routing.

I don't know, in fact, I don't have ANY concrete evidence that's even what it is, but I've looked into this pretty extensively before and it was all I could come up with. I may do a bit more digging but for now I think it's either that or as you say, some kind of marketing BS. The main reason I believe it to be that is because I know that the increase in default speed IS a thing and is right, and I can't figure any reason they'd want to use marketing speak to promote something that only directly relates to 2666mhz, not really a performance margin these days.
