That's alot of work using the hex editor...
Just use the AMD APU tuning utility...

JamesCJ / AMD APU Tuning Utility · GitLab

Unlock the full potential of your Ryzen Mobile APU with AMD APU Tuning Utility! Works on all AMD Ryzen Mobile APUs from the 2000 series up...

gitlab.com

I have it for my 4900HS G14 laptop and I'm able to overclock the iGPU with no issue.... or underclock it.
Give that a try!

 

@Cakewalk_S Only problem is, is it's a AMD A6-1450, so not Ryzen architecture. So it would be nice to create a editor for these types of GPU's, GCN 1, and 2 SoftPowerPlayTable Editor.

Thanks

 

I have a Samsung ATIV Book 9 with that same APU and I'm pretty sure I was able to overclock the iGPU somehow, but it's been a couple years since I've messed with it so I forget the details.

When I have a moment I'll try booting it up again and see if I can figure something out.

Did you try Afterburner already? I have some memory of successfully OC'ing an ancient AMD iGPU with AB but I could be thinking of a different machine...

 

I'm using these drivers from R.ID, WHQL-AMD-Software-Hybrid-Edition-23.11.1-GCNFlex-Nebula-Native-DCH. Nothing changes after changing the frequency in MSI Afterburner or in AMD Radeon Settings, tuning. I learned how to raise the overdrive limit to say 1500Mhz, from 520Mhz. The default boost clock is 497Mhz. It won't even go up to 520Mhz.
Thanks

 

Hi. I noticed that you have some skills in editing hex values in vbios. I am trying right now to unlock undervolting on my P4000 mobile card. This is quadro card and in quadro its locked. My max voltage is right now 0.95v and I would love to find how to calculate this in hex. This is pascal gpu. Do you know how to calculate this? thanks

 

@Raalph1 unfortunately I don't think nvidia has a softpowerplaytable in the registry for their gpus generated by MSIAfterburner.exe" /xcl argument.

Sorry bro let me know if you find something out.

 

My voltage fc curve is located in msi afterburner. This file is in profiles directory but its encrypted. I found someone that tried to decrypt this but dont know if it worked out.



Do you know what they are talking about?

 

@Raalph1
Let me take a look for a bit. Attach the file with the hex code.

Update
You'll have to correlate the values to actual numbers you see from operation of your hardware in the hex code. That means does 50299 mean anything? How about 502? Open AIDA64 enable the taskbar in AIDA64 paid for edition extreme, and run an NVIDIA GPU Dump & Attach the dump on 100% stock values & get that hex code from 100% stock operation as well to start.

There's exactly 50 complete 7BC4 related hex code values, and 2 more in red that start with A.

 

Thanks for your time and help. This vfcurve is not mine it was just an example.

From aida64 report made on 100% gpu usage. I noticed that my core voltage is slowly going up to 0.95v.

nv-020400 0000002E
nv-100714 00001615


So it seems that nv-020344 is voltage level count. Gpu boost function adds some mv after some time when on 100% usage and voltage is slowly going up to 0.95v. My voltage level would be nv-020008 ?? So for example in my vbios 0.931v would be B32F; 0.95v is D033; 0,943v is 3233.

What do you think?

 

Attach the dump file.

 

On 0% usage.

Now I think that even when I change gpu voltage, gpu boost will rise it. So I would have to edit all voltage values above to same level. Maybe easier option would be to disable boost clock and rise only default clocks. Then my voltage would stay on same level? There is no pascal bios tweaker so there is no point wasting time to find this without proper knowledge.

I cant understand why they blocked option to undervolt in Quadro cards..... this is propably one hex value to change in vbios from FF to 00.

 

@Raalph1 I have bios tools for pascal but only if its a discrete gpu dedicated card not integrated into the motherboard or mxm.

I need the report in English by the way.

Try this tool.

 

Its in english now. I used this tool and its working but it doesnt have option to change voltage or unlock undervolting. On stock clocks this card doesnt need undervolting. I was able to overclock it from 1250mhz to 1750mhz and memory from 1500mhz to 1750mhz.

Quadro P4000 Mobile Oc vbios. Working and tested.

This is vbios that I found on imac forum and made my changes to rise overclock of core and memory. Thanks go to user @m0bil for making imac vbios version. After my changes overall performance boost is about 30%. Its close now to gtx 1070m. Tested on MSI 4th gen laptop running in legacy mode and i...
