Core i7 14700K RAM Max speed (alien.top)

Hi there! I'm about to build my first gaming PC and I've already got a Core i7 14700k and a MSI MAG Z790 TOMAHAWK WIFI ATX LGA1700 Motherboard but now I'm wondering if its a good idea to get a DDR5 7200 36 GB RAM Kit. I've heard of people not being able to sustain these speeds in a stable way even with XMP. Would it be better to get a slower speed and more RAM? If so, what's a good RAM speed sweet spot. Thanks!!

I’m using a 7200 kit with no issues. Just turned on the XMP profile and go.

I was running 7200mhz RAM with my 13600kf and now with 14700k. It was only a problem in the beginning because my RAM kit was not supported by my Mobo. After BIOS update everything is fine without any issue. I have Asrock z790 pg riptide

On the same motherboard Lexar 6400mhz crashes with XMP :/ but they are not QVL not sure if this is an issue

Try to increase voltage. Also i dont know why but i also had to remove my second SSD. After that it was stable at 1.5v with 1 SSD

I’ve found on my z790 msi carbon 14900k, 7200 was pretty easy, just xmp and go, 7400 I had to adjust the voltages as another poster replied, 7600 I can boot but no matter what voltages/loosen timings I cant get it stable. But as others have said on 4 dimm boards over 7000 seems to be hit or miss while I do believe 7200 with the right settings is pretty common to get stable, over that is a crap shoot. Also look into tuning all your timings, a lot of gains to be had.

Some motherboards and IMCs might still require tweaking to get 7200 MT/s stable, but I'd say most Z790 and 14th gen shouldn't have an issue hitting 7200 MT/s.

Going over 7200 is problematic, as there's a pretty big wall for >7200 on 4 DIMM motherboards. Maybe 7400/7600 if you're lucky.
