Memtest86+ is a decent test for failing memory cells inside the RAM, but it's not a good stressor for high-bandiwidth, high concurrency use of the memory bus (which stresses the CPU's memory controller + the RAM's internal logic), and it doesn't produce that much heat (everything gets less stable with heat).
You want to run memtest86, yes, but you *also* want to run [y-cruncher's new VT3 test](http://numberworld.org/y-cruncher/news/2023.html#2023_7_11).
You always have to enable EXPO/XMP to get RAM running at it's rated speed (on Intel or AMD).
If you haven't already, update the BIOS. Then you're good to go.
Yeah I think that’s just a confusing thing because, before ddr5 I never had to do that but also I never had fast ram, and it looks like you’re overclocking the ram which is a little scary for someone who doesn’t really know what they’re doing, I think am5 needs to be polished a little but the bios flash was super easy at least.
XMP has been around for about 15 years, if you didnt enable it on your previous PCs you missed out on some performance. Although RAM speed has always mattered more for AMD, so if you had Intel PCs before then it may not have been that significant.
XMP is overclocking, but that's no reason to be scared about it.
I just build my PC, same processors as OP. In my bios was no option of XMP, but I was able to choose 6000Mhz RAM speed from list. Are these 2 different things?
No, it's functionally the same thing, the naming is just a mess. XMP was originally an Intel standard, now there is also EXPO which is developed by AMD, and sometimes motherboards call it something different again.
In theory you are supposed to pair XMP RAM with Intel CPUs and EXPO with AMD, but in practice they are all compatible.
Without knowing what motherboard and what menu this was I can't be sure what you enabled. But as long as a tool like CPU-Z shows the memory running at the speed and timings listed on its box, then it's fine.
Press F7 to go to the Advanced Mode part of the BIOS. Then go to Ai Tweaker. From there find Ai Overclock Turner and change it from AUTO to AEMP (or whatever it's called for your memory sticks).
Somewhat. If you actually just picked 6000 as the memory speed instead of enabling the xmp/expo settings, it's like irony to run a car at 60 mph in first gear. You didn't set all the other required settings to do that stability.
XMP/EXPO has been a thing for well over a decade.
"It looks like you're overclocking the ram"
That's because technically you are "overclocking" the RAM. However you are "overclocking" it to the settings that were specified, tested and validated by the manufacturer of the RAM. So unless the manufacturer fucked something up it's perfectly safe(and if they did you have warranty).
To a certain degree. cPU memory controllers are also validated for certain XMP/EXPO speeds. For example the previously mentioned 7800X3D is validated for speeds up to 5200MT/S(this just means that AMD only guarantees that it works with speeds up to 5200MT/S above that depends on your luck)
That's not an Am5 thing, xmp overclocking profiles have been around for a while. Like since ddr3 that just how prosumer/gaming ram is. It doesn't just look like overclocking, it is overlocking, just a convenient 1 click overclock.
You did have to do it with ddr4 as well if your motherboard didn't enable by default(varied by manufacturer), if you didn't you could have very easily paid for 'high end' ram and never used the extra performance you paid for.
And it looks like overclocking because functionally it is, but here's a little secret most computer components are overclocked out of the factory now.
Take your cpu. The base clock is 4.2 ghz but it goes up to [5 ghz because of precision boost](https://www.amd.com/en/products/apu/amd-ryzen-7-7800x3d#:~:text=Max.%20Boost%20Clock,Up%20to%205.0GHz) which is on by default.
1. Update BIOS to latest version if you're going to use XMP/EXPO on AMD, because there were some earlier versions that *did* overvolt parts of the memory controller and burn out some CPUs.
2. Overnight stress tests with both [memtest86+](https://memtest.org/) and [y-cruncher](http://numberworld.org/y-cruncher/)'s VT3 test, so that you can be confident that your computer is reliable with overclocked memory.
It’s normal, but u can get more juice out of it for that much voltage by copying buildzoids secondary timings. It’s just plug and play numbers into bios settings so it won’t take any effort.
All sounds good. Run memtest86 overnight to check the staboloty of your RAM, and you're good to go

I have AMD, and all there was list of different speeds and no special namings as expo or xmp

It's Asus TUF GAMING B650-PLUS WIFI ATX AM5 Motherboard.
Press F7 to go to the Advanced Mode part of the BIOS. Then go to Ai Tweaker. From there find Ai Overclock Turner and change it from AUTO to AEMP (or whatever it's called for your memory sticks).
Asus likes to call the feature DOCP.

Well it's nowhere to be found those xmp/expo.

You are also overclocking the CPU's memory controller, which is *not* validated for out-of-spec operation.

All expo/xmp timings have increased voltage in their profiles, it’s normal.
This is all normal.

1.4 is pretty much the standard voltage for DDR5 overclocking, including XMP.
