Most stable DDR4 speed for Z370

Hi all,

I'm debating what the best, MOST STABLE, ddr4 ram speed would be for the 8700k.

I remember reading that 3200mhz was considered best for z270 (something because the standard ram was 2400mhz), and that 3000mhz should be avoided.

Will this change for z370 (with a new standard of 2666mhz)?

Is there even such a thing as different ram speeds being more or less stable?

Most of the reviewers reached 4000MHz on good boards. I would consider anything between 3200-4000 good

 

Don't buy Apple M1 computers with 8GB of RAM

Ram will run at the speed, timing and voltage quoted on the box. Z370 will support damn near everything flawlessly.

 

I've only run into stability issues when OC'ing or tightening timings on ram, or with the initial BIOS' of AM4.

It was the thread below that I found confusing.

It seems that different straps (Bclk) plays a part in stability...

Anyone have any thoughts on this?

Well, it's very general. My RAM (Crucial Ballistix tactical 3000mhz) is 2400mhz that has an XMP setting to run at 3000mhz (15-16-16-35-1T 1.35v IIRC). So yes, 2400mhz RAM does overclock well. I even got it up to 3200mhz just bumping the voltage to 1.4v. But Crucial [and almost all manufacturers] label their RAM at the XMP values, guaranteeing the overclock. If it's already guaranteed then why worry about how much farther you can push it? Just run the XMP.

I've got the Z370-E, i7-8700K, am liquid-cooling it. Stock settings applied and it goes to BIOS just fine, but after applying the XMP profile for my DDR4-4000 ram (2x16gb sticks in A2 & B2 slots), it won't even go to BIOS. Anyone here with an answer?
