Evga Voltage Tuner

[Unwinder]

I just tried it on my PX3544-chipped G92GTS but I can't seem to find a i2c bus (0-99) that doesn't slap me with "invalid".

Please read my previous comment about I2C bus indices, altering I2C bus indices is not a correct way. You should try to probe difference i2c device addresses instead. Each I2C device address is defined by developers (e.g. ADT7473 fan controller use fixed address 2E, VT11xx VRMs use fixed register 70 by default, but it can be strapped to 7x AFAIR, etc).
You must have Primarion PX3544 datasheet to know where it normally resides. I've peeked inside reference 9800 GTX BIOS to see if it is initializing any I2C devices and it does seem to write something to I2C device 6A (writes single byte 86 to register 80 of this device). It can be Primarion PX3544, but I've no strict info about it because I don't have any info on this VRM I2C interface.

Okay, I think I might have a bit of a problem of understanding here. If

rivatuner.exe /i2cd

gives me this:

and

rivatuner.exe /ri<I2C_bus>,<I2C_device>,<reg>

is reading out a devices register located on one of 4 i2c buses, then why am I able to read out my VRM's 3D mode voltage register value with

RivaTuner.exe /sd0 /ri3,70,18 ?

If I understand this right I'm addressing device 70 on the 3rd bus from the first card, while that i2c scan dump oviously gives me 0c and 2e on bus 3? I found out that 18 contains my 3D VID with the help of this thread, what I'm not getting is that why the device addresses are not matching, but the whole command still works? What am I missing?

/I2CD or /I2CDUMP command line switches scan 0 - 4F address range only on all I2C buses. Upper address range (50 - 7F) is not affected by these commands because these addresses may contain some critical I2C devices (such as DDC for example) which may not like to be scanned and scanning them may cause different side effects (e.g. losing display signal when accessing DDC).

[overcrash]

Unwinder can't you make a program for the normal users? Mhz scrolling of core/shader/memory and vcore scrolling for GTX 2xx cards ?

[burebista]

I guess not.

So, like you already mentioned, I have to know the register address for VIDs of my specific VRM by reading it's datasheet and can forget about scanning the bus, right? Thanks alot for your assistance!

Even if there is a 'rolleyes' in your post accompanied by a big fat smiley, he already explained to users who attentively read this thread why he isn't implementing this functionality and why he never will.

yes, and it's a FAIL excuse in my opinion. RIVATUNER already has the ability to damage a card if a noob just batters in and clicks this and that. Allowing for voltage manipulation is hardly gonna result in every user frying their cards.

If he was so worried about users equipment, why spend 11 years developing a tool which gives access to all the "dangerous to touch if you're a noob" sections.....like clock control.....apply settings at startup.......power user tab....need I say more?

He's made and justified his decision, so go and live with it! Give a lil well-deserved respect to Unwinder!

I agree. First, it has already lots of options that a noob could use to fry his card, and second, if you put a big warning message and still the noob goes there, it's the noob's fault and I wouldn't support him or accept any complaints. You saw the warning, yours is the responsability.

Alright, after a bit of testing. I bumped the volts up to 1.3 on my 4870, hits 840/1100 stable just fine and lives for 15 minutes in furmark. Problem being, it gets a VPU crash within seconds when I try to play FEAR. 820/1050 is the max stable for that. This is at the same 1.3v. The temps are quite a bit lower than the furmark benching too. At stock volts both furmark and FEAR fail at the same settings, so I don't know what's up. Any ideas?

Same here. More volts using this method do nothing for gaming, still stuck at 850MHz with 1,26v

[KELL5]

He hasn't earned my respect yet......control yourself. You may love him....I don't.

He is the maker of RIVATUNER? What is rivatuner for? Now why would the maker of an OC app CHOOSE to LEAVE OUT the SINGLE MOST IMPORTANT OVERCLOCKING FEATURE TO BE CREATED SINCE THE CORE SPEED SLIDER?....and use a non-existent excuse for doing so?

Think like this.....

UNWINDER makes RT.
RT is GOOD.
RT gets BETTER.
everyone uses RT.
EVGA notice RT.
EVGA wanna copy RT.
UNWINDER gets a bung.
UNWINDER...he say YEAH.
EVGA use UNWINDER to make EVGA PRECISION.
EVGA have a few features to add to EVGA PRECISION.
EVGA make UNWINDER sign a contract.
CONTRACT says RT no getty our cool ADDITIONS.
ADDITIONAL FEATURES = VOLTAGE SLIDERS.

then you get to a point where you think...."yeah...sure.....I know why UNWINDER doesn't wanna add VOLATGE SLIDERS

It makes no sense to me that a legendary app maker would leave out legendary functionality.....no sense at all.

With this logic RT verision 2.24 will have POWER USER tab removed yes? Don't wan't noobs killing cards do we?

exactly.....this is nonsense.

[Renegade5399]

Except Unwinder is not helping develop the EVGA voltage tool.

[KELL5]

sorry my mistake, he didn't help...he done the lot himself

[Unwinder]

CONTRACT says RT no getty our cool ADDITIONS.

NVIDIA offered full time job for them a few years ago with "no more RT" and "no 6800 softmod" as one of their contract conditions. They failed. EVGA (or any of many other vendor I was working with) would fail to, if they try. Happily, they are nice company and in fact assist RT development. And comments of people like you leave nothing but bad smell. Not everything in this life can be purchased for money, boy. If you've never tried to provide free contibution to community, you'll never understand me.

P.S. Congratuulations, you've just earned my deepest disrespect.

Man, what is it that you don't understand?

Providing GUI voltage control makes it extremely easy to damage a card permanently. Unwinder doesn't want to get sued by rich noobs with overpaid lawyers. How hard is it to understand.

[burebista]

Man I don't understand what's your problem? RT is a free software. You like it, you use it as it is. Are you a power user? If yes that fancy EVGA voltage tuner already exist in RivaTuner so no complains. If no wait for OMG FTW XXX EVGA Voltage Tuner. Simple as that.
And indeed you should show at least a little respect for Unwinder's work because he give you a very powerful tool for free.
Sorry for my offtopic but I though that here on XS I don't see that guru3D "Unwinder is jerk/rude/whatever" attitude. Obviously I'm wrong.

[T_Flight]

I know this...

I bet when a mod sees this there's gonna be cookies at the very least, so I'd highly recommend that the people slamming on others here go back and clean it up before the mods have to, because if they do, the individuals that did it won't like the results. Consider that a freindly warning.

[SNiiPE_DoGG]

figures that a constructive discussion of methods for raising voltage would turn into this

[p2501]

Why not do this:

there's a sort of summary thread of RT volts functionality based on this thread here: http://www.xtremesystems.org/forums/...d.php?t=215521 . Constructive input and comments go there.

All egos, haters and naysayers just stay here and have your bash fest. Until mods have to step in, again.

[mikeyakame]

A few tips and tricks:

1) Once you've determined index of I2C bus containing VRM on some display adapter (e.g. I2C bus 3 on GTX 200 series), the same index can be safely used on the same display adapter model by others. Display adapters have a few I2C buses assigned for differed functions (e.g. for connecting DDC and for external devices like VRMs, thermal sensors, fan PWM controllers and for on), VRM's I2C bus is defined by PCB design so it is fixed for the same display adapter families.
2) Don't try to scan more I2C buses than the GPU actually has (there was some posting with attempt to scan buses 0-99 in hope to find VRM on G92). Each GPU architecture supports fixed number of I2C buses, e.g. G80 and newer GPUs have only 4 I2C buses, pre-G80 supports 3 buses, pre GF4 supports just 2 buses and so on.
3) I see that many users started to enable VT1103 plugin now. Please pay attention to the following info from RivaTuner's release notes and always remember about it when using this plugin:

"Please take a note that Volterra voltage regulators are rather sensitive to frequent polling and may return false data under heavy load, so it is not recommended to use VRM monitoring in daily monitoring sessions"

4) There were some questions about finalizing these new VRM settings in NVIDIA VGA BIOS. You cannot use Nibitor for that because the tool knows nothing about VRMs and works with BIOS voltage tables only, it is only allowing you to change associations between performance levels (i.e. 2D/3D modes) and 4 fixed voltages stored into VRM registers 15-18 by default. However, you can easily edit your BIOS with any hex editor to reconfigure initialization scripts writing these 4 fixed voltages to VRM during POST. It is rather simple task, taking my 65nm EVGA GeForce GTX 260 as example the following script command in VGA BIOS is configuring VT1165:

4D 80 E0 06 15 3B 16 31 17 36 18 2F 1D 55 19 01

The command uniquely identifies I2C serial byte write operation, encodes target I2C device address (E0 is 8-bit encoding of VT1165's 7-bit address 70 including read/write flag in the first bit), tells script processor how many bytes have to be written (06) and finally defines register addressed and data to be written to each register (register 15 -> 3B, register 16 -> 31 and so on).
The voltages can be different for different VGA BIOS images, so the easiest way to locate this command in any GTX200 BIOS image is to search for 4D 80 E0 byte chain.

Thanks heaps by the way Unwinder.

I tried searching for it in the bios myself, but gave up after a few hours of being unsure what exactly I was trying to find. Found it at E526h on my 280 bios!

Much appreciated for the explanation too

I don't want to argue with you unwinder. If you feel RT cannot cause damage alreay then you should check again. You've made RT with all the power it has and now shy away from providing users with an easy to use GUI to manipulate voltage control. I thought rivatuner was made to access functions and manipualte settings...maybe I'm wrong

Dont get on unwinder for riva cus you dont know how to take advantage of all its features.

exactly thankyou. so why does unwinder put them in RT? This could easily lead to an angry email for him

I never said he made (or helped) with evga voltage software....I said precision tuner.

edit doh i type slow

I know it can be done, but it's a long process where users can easily make a much more catastrophic error which resuts in higher voltage than was planned. The majority of users here could do all sorts of stuff to their machines through hex. I thought guys like unwinder made tools like RT to make it easier for users to accomplish what they want. Since when do users need a daddy to tell them when things are safe?

Tell me you enjoy having to use hex to manipulate your voltages? Say it. Say "Hi, I am very much in favour of keeping RT the way it is. I think it's a bad idea to introduce voltage sliders under a new tab with warnings inplace. I'd much rather have to edit values in HEX as this is much easier for me than using a slider."

So to turn up all other voltages in your machine all you need is the ability to read and click a slider. Everyone manages that ok. Ever heard of someone just trying 2.5volts to their cpu via slider?

I mean c'mon.......surely he wouldn't make the slider goto 7v or anything stupid.

Man, what is it that you don't understand?

Providing GUI voltage control makes it extremely easy to damage a card permanently. Unwinder doesn't want to get sued by rich noobs with overpaid lawyers. How hard is it to understand.

Then why does he allow users to overclock their cards then? You make no sense.

Asking why is not showing disrespect. If someone makes a decision and you don't agree with it you're allowed to express that opinion. I'm not name calling, or hassling unwinder off the forum. I merely expressed the fact I don't understand his reasons for leaving it out. If he'd said it's due to the fact it's very unreliable at implementing precise voltages or something then that would atleast make some sense. The fact he's made rivatuner (which is already the most powerful graphics card/system app I know of) with all the ability it has makes me confused as now he wants to protect users from themselves. Imagine he thought that just as he started to code RT in the first place......where would we be now?

I don't need a lecture on unwinder or his abilities. I'm perfectly well aware of the fact he's made RT for free to give to all.

[drizzt5]

I sort of agree with you that a voltage slider would be cool and if warnings were on it to use it with caution it could be very helpful.

But...

Then why does he allow users to overclock their cards then? You make no sense.

He allows them to overclock, but not to raise the voltage with sliders. You get artifacts from one, and the other gives you a pretty paper weight.

[BenchZowner]

Actually you won't get a paperweight even if you set the voltage to 1.6V on stock cooler.
Most of the times ( if not all )

Imagine he thought that just as he started to code RT in the first place......where would we be now?

I don't need a lecture on unwinder or his abilities. I'm perfectly well aware of the fact he's made RT for free to give to all.

Yours is a great mind, that can quickly analyze and rationalize things... I'm glad that you have the courage to bring things to light. Most others just want to respect Unwinder as much as possible just to encourage him to continue working on his wonderful RT project.

I'm completely with you, in bringing as many things to light as possible! Nothing wrong with that.. The bottom line here is that, as I already told Unwinder, eVGA has the balls to do it, and that he could also have the balls to do it, too. Heck, there's not even a warning in the motherboard BIOS to increase the voltage to like 2.0v or even higher, frying your CPU. The CPU heatsink could even be installed improperly, and the user could have already turned off the auto-shutdown feature based on temperature. Regarding the mobo/CPU, there's no "Daddy" around to even warn us on that.

We're all endowed with this "sacred" duty of making reason out of things. What is the REAL reason that Unwinder does not "want" to implement the same thing that eVGA is gonna implement? Usually, the most logical reason is the most truthful one. Once again, it's our duty to rationalize as many things as possible. It's our freedom of thought and expression, which is what has made America so successful in the duty of mankind.
