[Tool] AMD-Compute-Switcher for switch automatically to compute mode

[Paedy]

AMD-Compute-Switcher helps you to easily switch between compute and graphics mode.
It loops all registry folders of your AMD software and detects if the card is in graphics or compute mode.
If one is not in compute mode it will try to switch all to compute mode and if all are in compute mode it allows you to go back to graphics mode.

Download: https://mega.nz/#!Qgl3EYxJ!_7Aes-JHrnhGpIl2v_3EwG6E_jAsV_gjyj-Eg3IFGkY (VirusTotal)

Compatible with AMD Crimson software. (17.10.2 and higher because before there is no compute option or you can use blockchain driver instead)

Getting started:

• Run AMD-Compute-Switcher.exe
• Read the message, on top you see "switch to compute mode" or "switch to graphics mode". Press OK if you see "switch to compute mode. - this happens if one card is not in compute mode.
• Reboot

Changelog:

• 1.0.0: First release with simple switch

Special thanks to this post because I'm using this logic.

If you have any improvements you can post them here or send me a private message.

Thanks for the tools, will try it on my next build.

Any chance you can put it out on Mega.nz or Google drive?  The VirusTotal link won't let you download.

[CryptoWatcher420]

yeah I like to grab this as well but I don't wanna sign up just to download 1 file from a place ill prolly never use again

Sorry VirusTotal was only the document where you can see that there is no virus on it.


The forum here removed the link.
I added the mega.nz link now: https://mega.nz/#!Qgl3EYxJ!_7Aes-JHrnhGpIl2v_3EwG6E_jAsV_gjyj-Eg3IFGkY

Why is this an .exe executable instead of a simple PowerShell, for example, script?  It's much easier to vet scripts than executables with no source.

[Paedy]

executables with no source.

Yea you are right. But when I started I wanted to create a much bigger software as it is now.
I planned some features for the future so this is not the final version 

Source code from 1.0.0:

Code:

using Microsoft.Win32;
using System;
using System.Collections.Generic;
using System.Windows.Forms;

namespace AMD_Compute_Switcher

            var cardFolders = softwareKey.GetSubKeyNames();

            int tmp;

            foreach (var cardFolder in cardFolders)

any possibility to allow the program to detect how many gpus the rig has? I noticed it just sets 11 or 12 gpus to compute or graphics mode without actually knowing how many gpus its actually setting

[Amstellodamois]

Is it possible to delete the AMD settings program if you use that?
(To avoid it going back for default settings)



EDIT : You can rename it, so it doesn't load on startup.

If restarts from kernel power errors or overclocked failure right?

It was a good ideia, or if wattman can startup the profile we choose on restart like afterburner, right?

Im interested too

Agreed

[kisk]

Thank you for this. My control center would not save settings even after a driver wipe/reinstall. This saved the day!

[phuocduong]

Thank you for this

[preda]

what is this tool? i dont understand

i have blockchain driver and my amd rx works good

[Amstellodamois]

It's useful if you don't use the blockchain drivers.

[Bigdrago]

I have 13 gpu, But it detects 14? From GPU 0000 to GPU 0013

[Amstellodamois]

Maybe your onboard graphics?

[Bigdrago]

Maybe your onboard graphics?

Intel pentium with compute mode?

[jsanzsp]

very useful thanks

[Crate Mayne]

Solid tool, appreciate the work! Radeon Settings app is so unbearably slow to cycle through switching cards one by one.

And with that said, I'd hate to ask, but anyway to implement a detection of IGPU? Feel like I'm gonna break something hitting "ok" with the IGPU listed as one of the cards.
