MVOLT+ Cheat sheet/ guide

[u/Obvious_Drive_1506]

First and foremost, understand that anytime you overclock hardware it comes with risks. I made this guide in hopes to answer some questions people have been asking about the software, and as a starting point for anyone else. All of this information has come from my personal testing, or information from the overclocking forums.

All information should be in the pictures, but feel free to leave questions or comments for others.

From my understanding, some of the lower class cards do not have access to msvdd so the tuning may be different. I know this works with 5070ti - 5090.

This is awesome! Potentially dumb question, do I use MVOLT+ in conjunction with my already established overclocking tools like afterburner? Or do I turn off my overclock in afterburner and only manipulate values using MVOLT?

[u/HonkeyKong64 → u/TheMaadMan]

I have this exact same question as well! I have my oc/uv thru afterburner, but am wondering if I should only use mvolt, or use both, or just use my afterburner profile and then use just the nvvdd and msvdd sliders in mvolt?

[u/FacelessGreenseer → u/HonkeyKong64]

You can keep using Afterburner for everything else, and use mVolt+ for "xBar Clock Offset" overclock. In the top-right corner of every box on mVolt+ you can see in the image above, there is an enable/disable button. Disable everything except for XBar overclock, and use an easy (depending on the GPU) around +200 to +300 Mhz "xBar Clock Offset" to get a decent boost in performance.

[u/Obvious_Drive_1506 → u/TheMaadMan]

You absolutely can just change xbar and sys clock in this along side afterburner

[u/TheMaadMan → u/Obvious_Drive_1506]

Heck yeah. I like being able to keep afterburner for the RTSS on-screen monitoring. I'm gonna give it a shot. Thanks!

[u/ZeneticX → u/TheMaadMan]

I was originally using Afterburner alongside Mvolt (just for the xbar oc like everyone else), but decided to just try Mvolt alone. With the same settings I was able to score ever so slightly higher with just Mvolt. And someone else told me here its better to have 1 oc software rather than 2 incase of any conflicts or issues. I'm currently still on Mvolt only.

[u/TheMaadMan → u/ZeneticX]

I can see why it might cause issues. Its writing to the same place and these kinds of instructions could be sensitive to two different programs trying to modify it. I just have other apps dependant on afterburner. What were the score differences like? Anything more than margin of error kinda stuff?

[u/ZeneticX → u/TheMaadMan]

Just a 1 - 2 fps improvement in Steel Nomad so yeah nothing significant. But hey a gain is still gain if it doesn't have any drawbacks.

[u/big01254]

Will we ever see mvolt+ for Ada?

[u/jue2wang4 → u/big01254]

look up axia in this sub

[u/JudgeFormer6013]

Xbar volt offset +50 help my card to 690mhz Without it stuck at 350 mhz

That only meaningful gain that still efficiency

[u/foundingfatfather]

Hi man, thanks for that. Could you give us some insights on undervolting?

[u/Obvious_Drive_1506 → u/foundingfatfather]

Sure! It has a VF curve setting inside of the options tab that's very similar to afterburner but arguably easier to use. That's your typical use that most people know.

You can however limit maximum voltage to say 900mv and just do +900 or whatever your usual settings are and it'll do the same thing.

I did this process which is a little different. Firstly 1v maximum, and set a 3.1ghz maximum clock. Then just slowly increased the clock offset and got to about 600 and it crashed. I then lowered max clock to 3.0ghz and could push further.

I'd suggest trying both and see what works best for you! Msvdd doesn't play a large role in power consumption, but if you were at say 2.7ghz core, you could get 2.7ghz crossbar and set voltage to 1v on msvdd for some marginal gains

thx man!

[u/baro55]

thank you

[u/sangseng]

Working with dual gpu ?

[u/Obvious_Drive_1506 → u/sangseng]

It can but I'm too poor to test

[u/DullSatisfaction3865]

Great info! Thanks. Also on overclock net forum, half way down page 2019 (post #40,378) of the 5090 forum, there is a great post that explains what all the options do, and how they affect the gpu. Good read. Overclock.net Mvolt option explanations

edit for spelling

[u/TorrentFire]

So with this, this is the entirety of your OC, right? You don't have a VF Curve declared in Mvolt or aren't using Afterburner on the side right?

How much perf over stock does this Mvolt config give you?

Where would you say that your card is in terms of silicon lottery? Do you think most 5090s could handle this same Mvolt config?

[u/Obvious_Drive_1506 → u/TorrentFire]

Going with only xbar and its clock gives me 500 points on steel nomad. I run a strange hybrid where I put everything between 820 and 900 to +800 and then anything above 1v to +250 and sort of feather in the rest. It was +300 but it crashed in light loads.

[u/TorrentFire → u/Obvious_Drive_1506]

So your only using Mvolt, no MSI Afterburner, and no VF curve in Mvolt. Just the stuff in the screenshot yeah?

[u/Obvious_Drive_1506 → u/TorrentFire]

Just mvolt, all settings + a VF curve edit that I mentioned earlier in mvolt+. It does everything afterburner can

[u/Hongthai91]

Hello, I’m not very familiar with overclocking and usually rely on Afterburner to create a curve. Could you kindly explain the benefits of using this tool instead? Thank you.

[u/Obvious_Drive_1506 → u/Hongthai91]

If you're new, just use your afterburner profile alongside this. Just enable msvdd voltage, xbar and its clock. Msvdd maximum to 1050mv and increase bar till crash then lower, same with sys clock. Shouldn't change power draw and can work together.

[u/ComputerUpgrader]

what about laptop GPUs, can i undervolt stuff other than GPU core to have more efficiency using this program?
