GPU Voltage Tuner - All-new intuitive voltage tweaker!

[TiTON]

AgentGod - Very nice app. I will have to give it a try this week.

I do have a question.. can your app quickly apply same voltages to all cards? For example.. can I say 1.4v - All Cards (Gpu 1 / 2/ 3/ 4), or do i have to set each votlage separately per card?

AgentGOD,

something is not right with that util on my Club3D reference design HD4870X2. If I select 1,3V it warns me about setting a voltage higher than 1,45V lol.
If I still set it Rivatuner shows 1,59V VGPU for that core. Thankfully all HD4870X2 don't allow more than 1,35V to the core so it didn't kill my card, but you might want to look into that

The number of GPUs you select in the "Voltage Tuning" section determines how many cards it will set to.

Could you show me a screenshot of this? Visuals will make it more clear.

About readme:

Compatibility:
Most GT200 GPUs are supported, some G92 GPUs, and all RV770/790 GPUs
above 4870, and several custom PCB boards. If you aren't sure, just
try it and see if it works

Some G92s? For example?
I can't think of any other G92 board with Volterra VRM chippery other than 9800GX2.

Thank you very much, very good tool.

Sure...

First image, me opening up your voltage tool first, then opening Rivatuner to monitor the settings. So far, everything looks ok but for the fact it shows 1,2375V as starting voltage, should be 1,2625 obviously.



Next, I try for instance 1,3V and what happens is this:



Now I disable the limit and set 1,3V regardless.. here ya go:



Bang, it sets maximum voltage to both GPUs. This happens with every value I chose, ie 1,1V gives the same result, so does 1,0 etc.

Note that the card is running Folding@Home, which is why the 3D clocks are active and the card is loaded. Current is around 48A at stock volts, goes up to around 52-53A (--> 1,35V max as you know), so I am guessing the card runs at 1,35V real as soon as I use your util.

Note that using Rivatuner directly to change voltage worked fine for me, however it did not yield me any core speed gains so I dismissed it.

[AgentGOD]

I see what's wrong. My code for setting the voltage is using US numbering system while the others become overridden by your local European one. And when that happened, the numbers were being compared to each other in different systems and it got confused.

But I've fixed this in the new version, which I will be releasing shortly.

[AgentGOD]

Updated to v1.3
- Fixed a bug that caused wrong calculations due to different locales to en-US

[hersounds]

tested on ATI SAPPHIRE HD3870X2 and runs fine below shows an image with the default values without touching anything, the question is,how much i can upload the voltage with securely, taking into account air cooling ?



here the options, waiting for your feedback

[AgentGOD]

1.5v should be your absolute max, 1.45v to be sure. And always watch your temperatures, and don't give it excessive voltage (only use as much as it needs).

Nice work AgentGOD!
I am running an English OS but with German keyboard layout...

Great tool for undervolting while folding, gonna save me some elec

thanks so much, all run fine now.
good tool

[AgentGOD]

Excellent!

Awsome TOOL

i have 2 feature requests

when you select automaticly set voltages at windows boot, could you also have a box that says minimize to taskbar, as i want to keep this program running all the time becuse that way riva is running all the time
instead at the minute when system boots up your program sets the voltages then shuts down but its conflicting with rivatuner if i have rivatuner starting up at bootup your program wont set the voltages
but if i have your program set to boot up and riva not to boot up then it means i have to start rivatuner up manuely.

the next option if you could add it would be sweet is fan control under 3d.
so when i enter a game the fan spins up to say 85% and when i exit game the fan spins down to default speeds.

again great program

What do you mean?

Hi AgentGOD

It Not Work For My 4870X2
When I Click In Software After Few Second Not Happening And Crash Reset Win

Hi AgentGOD

Steps to reproduce this problem? And screenshots please.

[ViViD]

OK Soon Take Shot But When Click In Voltage Tuner Reset Win Not Happening To Take Shot
Maybe Take Shot As Riva Tuner Hardware Monitoring?

Should I Run Test GPU When I Run Voltage Tuner? I see In Other Shot GPU Usage In 100%
I Can not Understand Why GPU Usage About 100%

Any thoughts about the ATI 4770. 40nm should make for some good overclocks, but I don't really want to flash the BIOS to asus, allowing me to use the asus voltage tweaker. I mean if that works, this should, no?

[Dadi_oh]

Awesome program. Thanks man.

[Paxi]

This has been ask before but i haven´t found an answer so far.. As far as VMEM is also showing up in Rivatuner, is it possible to adjust VMEM also with softmod?

Unfortunately, most likely not.

Thats because new single PCB 295GTX didnt got volterra

[AgentGOD]

Unfortunately, NVIDIA cheaped out on you guys and swapped out volterra for a cheaper regulator.
