I can confirm that now, just tried to set 1.4V and my DMM wouldn't give me any higher values than 1.371V, identical results (reference sapphire hd4870 X2). So this should be the OVP then? Curious if anyone can find a way around it...Quote:

So perhaps they really simply put some diodes in the circuit to limit the voltage. Have a thorough look at the ouput of the PWM and see if can find some diodes there. Perhaps it's really that simple.
Yup, I don't think it works on Asus 4850's. I tried it on both of mine... and got invalid sadly :( Also it does not work on 4830's according to here.Quote:

I've updated the original post with links to the "unocked" Evga Voltage tuner.
Now works on any brand video cards, and removes the slider limitation.
Wow, some of those programs are great! Good thread!
I still get 4 invalids though for both cards :)
The link for the unlock patch appears to have been removed.
check again, just updated it ;)Quote:

Just wondering now how far you can push it...any ideas?
Edit: Just read the hole thread, and saw that I misunderstood.
I can only run higher voltage on Core 1 on my 4870X2, Core 2 seems stuck at 1.26v. Any ideas?
None of these methods work for me on my Asus 4870 Dark Knight card.
I2C bus returns invalid on all 4. Am I out of luck here in that my card doesn't even have any model Volterra?
how the heck do you get anything off that mediafire site !? signed up and wtf ?? nothing happens
one problem, every time i restart pc i need to do everything again?(2d and 3d volatges are stock)??
Show us the command line you're using.Quote:

Neither will work on an X2 (current versions)
Its a lot easier to just learn the basics, very simple tbh.
It did not work on my 9600GT. Is there any other softmod operating on G9x boards?
Well, the patched eVGA Tool didnt work on my reference MSI 4870 1GB OC edition. Installed the program, then installed the patch, it said it was applied succesfully. I decided to do a small voltage bump to 1.275v (1275mV) and hit apply but nothing happened, voltage slid back to 1000mV just like what it was set to in the beginning. Also tried adding it to startup and rebooted, still nothing. Dont know if i'm doing something wrong or it just doesnt work on all 4870? I was expecting it to work on a reference card like mine after the patch. Anyone has this problem with 4870?
I have a the same problem with my visiontek 4870 . Any ideas guys ?Quote:

That one actually worked on my 4870 and my load volts went up to the value i set. However, i havent tried raising my clocks yet but will do soon and report back. You may want to try that, it reportedly works on 4870. Keep in mind that with increased voltage better cooling may be needed as well.
Forget about using EVGA GVT with ATI cards. This tool doesnt have low-level I2C hardware abstraction layer and it is able access it by means of ForceWare's I2C access API. So it will not be able to work with VRMs connected to I2C bus on ATi hardware under any conditions.Quote:

how to fast enable again new volatges on boot??
i dont want too every restart to do everything from the beginning .
i dont know which method are you referring to but if you used the RivaTuner voltage adjustment method then it doesnt have to be done every time you reboot. If you follow the link i posted above on page 5 of that link the guy explains how to add your custom voltages to startup. I just did it myself and it works.Quote:

i have a 3650 ( agp ) by sapphire ( 55nm ) is this information correct?
I've added small improvement in CLI of upcoming RivaTuner v2.23, it will simplify command line based programming of VRMs on SLI/CF systems:
- Improved command line interface. Added /SG and /SELECTGPU command line switches allowing selecting tweak target by GPU index rather than by logical display device index represended by previously available /SD and /SELECTDEVICE command line switches. New command line switches are supported for both queued hardware access scripts and for command line based GUI device selection changing.
