MSI - MOBO - settings in bios different from other motherboards. Need msi thesaurus.

[south wind]

Hello.

I'm looking for a few things in my msi mobo. I can't seem to understand first of all.
1: Where is the different XMP and EXPO? There is for sure XMP. but does msi have something different for EXPO?

2: Eco mode on Bios settings dont seem to exist where the internet tells me it should. (does not exist in my PBO)

3: What is the difference between doing overclocking in the settings and overclocking in the OC section?

so far. those are my biggest unknowns that the internet tells me, but its not true. hahah.

thank you so much!!!

I don’t know everything you are asking about, but will help where I can.

1. XMP is for Intel and Expo is for AMD, so it depends on what CPU you have. They both do the same thing and “overclock” the RAM to the rated speed on the box, otherwise it will just run at a base speed of 2133mhz for DDR4 or 4800mhz for DDR5 kits.

2. What are you trying to accomplish with eco mode to potentially help what category it should be listed under.

3. MSI’s BIOS can have an EZ (Easy) menu and an advanced menu, so they might be overclocking the same thing but have a different look. What are you trying to overclock?

It doesnt have these two different ones. I'm asking because it only has XMP and i am AMD/expo

[south wind]

i feel like that is it. They do cancel out the other.

[zenith siren]

Can you take a photo of the main page of the BIOS?

[south wind]

I'll keep looking. thank you.

[zenith siren]

Can you take a photo of the main page of the BIOS to so we can see what it says?

[south wind]

ok. so if i have the frequency set in setting AMD OC. the xmp would be overwritten? or the other way around? or do nothing?

do nothing cause i have no expo just xmp

or

**

i will still get you picture

[zenith siren]

XMP and EXPO are both profiles that change a number of settings as part of a profile that was tested and deemed stable for that kit of RAM that you are using.

[south wind]

ook. what will happen if you use xmp when you have an amd?

[zenith siren]

That is why I am asking for a photo, because that isn’t how it works.

[south wind]

ok . brbr

[south wind]

I see there is a high efficiency mode. Is that eco? It’s behind the drop down

In the xmp pic

Everywhere says the eco mode is in pbo

[zenith siren]

Ah, I see what you are referring to. This is what happens when motherboard manufacturers take liberties with branding and labels. Notice how there is an A in front of XMP. That just means it is for AMD.

XMP or Extreme Memory Profiles, is an Intel technology that allows you to change multiple memory settings, whereas EXPO is the AMD equivalent. Both methods enable higher memory speeds simply by selecting a profile in your motherboard BIOS, providing you have the correct supported RAM.

[south wind]

Thank you! I was wondering why I only had 1 option and every other msi person out there had two!!!

Is that why the eco mode isn’t the same? Hahah

[zenith siren]

While they might technically do different things on the back end, EXPO and XMP do the same thing to overclock the RAM. They can call it whatever they want, but it is a one click solution for both.

[south wind]

Totally.

[south wind]

What about the eco mode? Is it named something different and put somewhere other than the pbo?

[zenith siren]

That I don’t know, but I know there are single option settings on motherboard that add an extra overclock to the CPU and, again, each MB manufacturer calls it something different.

[zenith siren]

What is the goal with eco mode that you are trying to accomplish?

Like you put eco mode on and “this” will happen?

[south wind]

well. there are some OC settings that help your Wattage for $/hashrate for mining. So i'm just trying to adjust based on hashrate, wattage and so on.

i'm used to doing it on other MOBOs. just got msi this time and its so backwards

[zenith siren]

So you are trying to find a setting that will undervolt your CPU from the typical base voltage?

[south wind]

yes. besides the AMD OC. I want to be able to undervolt, but use all the ways in which to do so. So that i can go through 1 by 1

not just setting the voltage

or does it matter?

[zenith siren]

Looks like that Reddit page gives pretty good explanations of heat profiles and then you go into the TDP settings and pick a profile from there that will limit performance by keeping the wattage limited.

[south wind]

thank you. I've been doing some basic undervolting other ways. Just was not sure if there was something i was missing. Thanks for the info.
