Just to show you it works, at least on some cards. My 4870X2.

------------------------------------------
Open a command box, go to the Rivatuner folder.

Code:

RivaTuner.exe /ri0,70,1A
RivaTuner.exe /ri1,70,1A
RivaTuner.exe /ri2,70,1A
RivaTuner.exe /ri3,70,1A

RivaTuner.exe /ri1,70,1A returned 0a, the rest say invalid

So on mine 'ri1' is the voltage control, then probe the controller for VIDs.

Rivatuner gives the following - 1.06v idle voltage, 1.26v load voltage.

The results are below, example (45 x 0.0125) + 0.45 = 1.0125v

HEX > DEC > VID

RivaTuner.exe /ri1,70,15 > 2d > 45 > 1.0125v
RivaTuner.exe /ri1,70,16 > 31 > 49 > 1.0625v
RivaTuner.exe /ri1,70,17 > 39 > 57 > 1.1625v
RivaTuner.exe /ri1,70,18 > 41 > 65 > 1.2625v

So #18 is the 3d voltage to raise.

Say 1.3v vcore

VID = (voltage - 0.45) / 0.0125

(1.3 - 0.45) / 0.0125 = 68 or 44(Hex)

So the command line is

RivaTuner.exe /sd0 /wi1,70,18,44 /sd2 /wi1,70,18,44

Be careful with that final hex value you can easily overvolt your card and of course you do so at your own risk. Just to be safe only change the voltage once per boot. Had a serious overvolt when I did more than one change, dunno why.

If you want a batch file this is the one I knocked up. Edit this with your own values, path etc. Paste to notepad, save as vgpu.bat or what you like. I know this one works up to 1.4v (1.37v actual measured), VRM current scales up to a point.

Now someone make a tool that does all the maths for me so I don't have to think.

Run these:

1.

Code:

RivaTuner.exe /ri0,70,1A
RivaTuner.exe /ri1,70,1A
RivaTuner.exe /ri2,70,1A
RivaTuner.exe /ri3,70,1A

One 'ri#' will return a value, put the one that responds in these.

2.

Code:

RivaTuner.exe /ri#,70,15
RivaTuner.exe /ri#,70,16
RivaTuner.exe /ri#,70,17
RivaTuner.exe /ri#,70,18

Each one gives a value, post them back here with your 3d voltage from Riva and your target voltage and I'll do the maths.

My 4870 1gb only managed to OC to 825/1055 without artefact, so if do this will i be able to OC more?
Thanks

Will the core overclock more? Usually yes, but it will get hotter.

willy said:
How do i know the safest volt for mine?

You don't. But +0.15v should be fine, depends on temps/cooling. Go in small steps though, temps will rise very quickly with voltage (power).

BTW: I've put mine in a bat file with selectable voltages, works great.

willy said:
None of them return a value for me?

All come back with invalid? You're running in the Rivatuner folder?

fornowagain · 27 Jan 2009 at 18:42

willy said:
So how do we check what volterra on each card?

Its written on it.

Plenty of 4870 getting results. Non-reference design seems to have issues. Different controller, probably the cooler phase design.

fornowagain · 27 Jan 2009 at 18:57

Post a screen shot of the cmd box with your commands, maybe I can see something wrong.

G:\Program Files\RivaTuner v2.22 is where rivatuner is installed to

Open the cmd prompt

willy said:
So i need to take the card of the mobo then, i've got Sapphire ones, so is that non reference?

I don't know, does it have the standard looking cooler? The vast majority are reference.

fornowagain · 27 Jan 2009 at 19:41

I'm wondering for those getting invalid, when you open the monitoring in Rivatuner are you able to see the GPU Voltage Regulator output? If not check the necessary plugins are installed/enabled. Make sure there is a check beside VT1103.dll on the plugin list.

fornowagain · 27 Jan 2009 at 20:31

Not there, open the monitoring page and look for a trace named 'GPU Voltage Regulator output'.

ViRuS2k said:
question ?

when useing these voltmod ect up to 1.3v ect as long as i keep the temps under 90c should be fine right ?

115c is the thermal throttle right ? so should be fine correct ?

That's up to you, 90C wont kill it though, as they're designed for high temps. Personally I'd not want to see temps that high for long.

willy said:
Here's mine, not showing under monitoring but when i checked under setup --> plugin, it's already ticked and also this one, is this mean that i have vt1103?

It means you have the plugin yeah. Check on the monitor page under setup and see if the gpu voltage option is enabled, you may have to scroll down the monitoring page to see it.

I personaly am getting sick and sick of not seeing a better cooler coming out for the 4870X2 series cards..

ATI are always the bottom of the foodchain compaired to nvidia. Im getting sick of it.

There's always water, trust me that works REALLY well on the X2.

Greebo said:
One small mistake with your batch file. You have used the decimal value instead of the hex value for the default voltage so it will be putting about 3 volts through the card . It should read 41 and not 65.

Nah 1.7v ish, lol. Well spotted. Good case in point, never copy values. Always do you own calcs.

Glad it worked though, must be a reference card then?

thanks for that batch! changed all the bits i needed to and it works brilliantly with my 4870x2 =] im wonderig, what would u recomend i set the memory to? because im not sure what to overclock the memory to on this card. and what what overclock do u think is possible with 1.3v? my card is watercooled btw. thanks =]

1.3v isn't much of a bump, 1.4v is fine under water for an X2. The bandwidth at 1000MHz (4000MHZ effective) is massive and more than enough. I don't see a lot of gains going higher tbh.

Aekeron said:
Just tried this and it seems to work well (thanks for the batch - though I took your advice and checked the figures)

Any idea of an acceptable temp for the VRMs? They seem high to me but perhaps they're meant to be...

What's high to you? VRMs do get seriously hot. On mine, even under water they're quite a bit hotter than the cores.

fornowagain · 28 Jan 2009 at 00:29

Aekeron said:
Well, at 1.3 and my fan locked to 35%, the VRMs went over 80 before I closed furmark.

I realise that they can probably go a lot higher than that but I guess I just wanted to get an idea the sort of temps I should expect on them

Volterra PWMs are rated for 125C, under a 100C is fine. If you're worried try and get some air over them, spot fan can work wonders.

Extreme voltage version for X2 in the OP. Remember to check the values and paths.

updated OP.

Btw, it couldn't find the "RIVAPATH " handle because of the space.

snip

Your registers converted

Register 15 - 38 = 56 = 1.1500v
Register 16 - 36 = 54 = 1.1250v
Register 17 - 35 = 53 = 1.1125v
Register 18 - 31 = 49 = 1.0625v

=================

Go to the OP, I have put a batch for the 260 & 280. Same warning. Check the values and path, you do so at your own risk.

fornowagain · 28 Jan 2009 at 17:22

The core and shader are under the same voltage. You may just be at the limit of the shaders.

Ummm thx for taking the time to do that but when i run it the box opens correctly but when you then press a number for the voltage you want it just closes and no voltage is changed. This is the same if i run as admin aswell.

I'll have a look

Dug out the DMM, looks like my 4870X2 is OVP limited to 1.37v

fornowagain · 29 Jan 2009 at 21:33

You're not going to do any damage tbh. Most of these cards have over voltage protection circuits, from my testing this method does not override that function. Take the trace below from my 4870X2. Increasing the voltage with a game running minimised. As it reaches 1.35v you can see that the load current doesn't get any higher. I checked with a multimeter and it limits around 1.35-1.37v. No matter what voltage I select the actual core voltage just can't go any higher. I don't have a 260/280 to hand, but the OVP will be around 1.30v.
