I have the Sapphire 4870 1GB, running Vista64.

I load this plugin as instructed. But I do not see any voltage graphs. The only plugin I have checked is the vt1165, but it doesnt matter if I have it checked or unchecked. I only get Core Clock, Memory Clock, Core Temp, MemIO Temp, DisplayIO Temp, Shader temp and GPU load. In the list of data sources there is no option for any voltages.

I dont get any log file, I dont get any errors either.

after installing vt1165 plugin, click setup

Core clock is resetting to default every time a new application starts. I running 835mhz @ 1.3125v @ 4870 512mb. In 3dmark 06 it starts @ 835mhz and next bench in 3dmark it resetting to default 750mhz. So it is just GT1 who run @ 835 core. GT2 start @ 750 core.

How can i fix the resetting of the overclock? Can someone other test this? just have monitor up when running 3dmark to see.

And this does what? It shows me data sources, which I explained, and also the plugins button which I explained.

Once Rivatuner is installed, open it and go to the Hardware monitoring section...1.
Make sure your card you are changing voltage for is selected from the drop down menu. Select the Setup option from the hardware monitoring window in the bottom right...2.
Then select the Plugins option in the bottom left...3.
When the Active plugin modules window opens, scroll down and make sure there is a check beside VT1102.dll...4.
You should now have the Voltage regulator output, V as one of the monitors in the hardware monitoring window, you may have to scroll down to find it. If not, then go back to the Hardware monitoring setup window and ensure there is a check beside Voltage regulator output, V.

Seriously.

I appreciate you trying to help, but did you even read what I wrote?

Maybe your system is just different than everyone elses?

Best of luck.

Doubt it. Just doesnt seem to be using the plugin for some reason.

Just took another RivaTuner reinstall, now it works.

I may have to find a new BIOS. I was running 830 before, now I just bumped the voltage from 1.2625 to 1.2750 and I can easily get 850.

Well I can't even get the VT1103 to display any kind of voltage statistics either -- The options to view it are simply not there as choices to view. It leads me to believe something is not correct with my RivaTuner, or else I've been reading reports of Asus cards failing with all these options.

I'll go hit up the other thread and see if any other Asus 4870 users are getting this problem.

fgw,

Supporting cards is about to get harder, sorry mate. The volterra isn't going to be around on the 260's soon.

good to mention it once more for everybody who missed this in my first post!

no, unfortunately i have no idea as nvidia is not supplying specs for their processors. so we are at our own and need to wait for experiences of other users.

any windowed mode doesnt change voltage its only when i load a game that it does do you have any suggestions

ATITool artifact scan, furmark, F@H GPU client all will run 3D mode.

Try installing/reinstalling the C++ redistrib.

I'll write up the code for Nvidia cards to get VID bit mask for 3D performance level and return it to a struct you can pass to the function for WriteI2CEx() so you can just pass for ie st_GPU_VIDMap->vid_3d which will be BYTE type, so you don't need to cast it.

I'll private message you a code snippet to add to your code mate when I'm done. I'll try do it tonight, otherwise tomorrow night. Want to make sure it has no major bugs and works as expected. You'll just need to add code snippets to the VT1165.h and VT1165.cpp and change the prototype for the function that is doing the WriteI2CEx().

I have no idea how to do on an ATI card, as I don't have any at home for testing so maybe Unwinder can help me here, I'll send him a message and see if he has some time to give me a quick VID to Performance level mapping description for ATI cards. ]

both gpu usage goes up but the gpu and mem stay the same also the volts stay at 1.1v unless i load a game the it hit 1.265

I just manually set the clocks in RivaTuner first and the card jumps to 3d voltage without having to load anything else.

that probably means that f@h isn't loading gpu either enough, or driver issue where it isn't being detected correctly to switch to full 3d clocks.

I'd say check F@H forums or try a different driver version and see if its any different.

@mikeyakame, if there is no way for soft mod any chance for pencil vcore mod for GTX 285.

You've asked before about nVIDIA SMBus Dump, have you see it here http://www.xtremesystems.org/forums/...0&postcount=68

Thanks mate.

I couldn't tell u much about modding the hardware on a 285, don't have one myself to look at. Quite a few vmodders here should be able to give you a helping hand though!

you can further reduce polling rate by also disabling all datasources supplied by the vt1165 plugin you are not really interested in.

interested in your results!

Seems it was stress related, after disabling the vt1103 plugin it still displayed some irregular readings after a short time under load, but once I disabled all other data sources except for voltage readings the voltage data supplied by the vtt1165 plugin was constant.

thankyou so much for this tool(cant wait to try it out)....

you are a real addition to the tech community....

hi guys!
I'm dario from Bari (Italy)

first of all:sorry for my bad english!

i decided to register at this forum because i want to say: thanks a lot for this wonderful tool !! It works on my gtx 260 216 sp BE but there are some problem: a lot of positive spike and some voltage drops...and let me be more quantitative:

i'm testing only at small overvoltages: 1.2000 VRM output with a small sampling time (0,5s).The thing that seems strange is that the magnitude of spikes are function of the voltage that i decided to set. For example:

If I set 1.1250 (the default value on my be for the 3D profile) and i'll find some 1.1375 small spikes.

If i set 1.2500 i'll find a lot of absurd 1.6000 spikes.

If I set 1.2375 i'll find no spike but some voltages drop.

I believe that this are not real voltage fluctuations because:
1) the vga is stable at clocks that i can't reach before
2) if voltages drop are real the vga would crash :confused:
3) if they are real they can't be fuctions of voltage set by the user

I'm waiting for yours useful tips!

dario
