How to adjust voltage on Sapphire 7850?

I have a Sapphire 7850 and while it handles gaming great it has pixelation and screen flashes on desktop, or while just doing basic tasks. I worked on this for 3 days and found that when the card is not in AMD "overdrive" mode the clocks and voltages drop very low, and this causes my problems. After looking on the forums alot of people have contributed this to low clock speeds, however I have found that it is caused by low voltages, not clock speeds.

So i adjusted my voltage in the .xml file called "Profiles". I noticed there are two settings:
0= not in overdrive
1 = overdrive

Here is what I changed it to:

<Feature name="CoreClockTarget_PCI_VEN_1002&DEV_6819&SUBSYS_E218174B&REV_00_4&B77C4C1&0&0008A">
<Property name="Want_0" value="30000" />
<Property name="Want_1" value="95000" />

</Feature>
<Feature name="PowerControl_PCI_VEN_1002&DEV_6819&SUBSYS_E218174B&REV_00_4&B77C4C1&0&0008A">
<Property name="Want" value="0" />
</Feature>
<Feature name="MemoryClockTarget_PCI_VEN_1002&DEV_6819&SUBSYS_E218174B&REV_00_4&B77C4C1&0&0008A">
<Property name="Want_0" value="15000" />
<Property name="Want_1" value="120000" />

</Feature>
<Feature name="CoreVoltageTarget_PCI_VEN_1002&DEV_6819&SUBSYS_E218174B&REV_00_4&B77C4C1&0&0008A">
<Property name="Want_0" value="1000" />
<Property name="Want_1" value="1150" />


Changing the voltage to 1000 eliminated my problems, it was origionally set at 0825.

Now I come to the reason why I am writing this and my questions:

When I am typing somehting or surfing the net the gpu uses that "0" setting with the clocks at 300/150 and voltage at 1.000V

When I am in a game it jumps to the "1" (overdrive on) and pushes the clocks to 950/1200 and the voltage to 1.150V, which works great, awesome performance and no screen pixelation or screen flashes.

But when I do somehting like watch TV or a youtube video the GPU pushes the clocks a little higher 450/1200 and the voltage to 0.900V and this creates a problem. The screen begins to flicker and and become pixelated, it is the 0.900V that causes the problem. Since factory settings have the idle at 0.825V, which i changed, the next step up for voltage is 0.900 and this is too low, but I dont know where or how to change this.

If I could just push that second setting to 1.000V instead of 0.900V it would eliminate my problems. But I only have control of the idle and the overdrive, anything inbetween is out of my hands.
Where would I go to change this?

FLOODS!

You have 2 threads for this problem it makes it hard to help, you should probably copy and paste this info into the other post and then ask to have this one deleted.

Floods7, I merged your other two threads, since they were directly related. This one is fine because there is a different question.

Is this (Profiles.xml) file found in C:\ProgramData\ATI\ACE ?
or found in C:\Users\%user%\AppData\Local\ATI\ACE ?

I was recommending he merge it not because of the questions but because of the GOAL he is trying to achieve the same thing so I figured it would be easier for him if he had it all rolled up into one thing as people are going to make some recommendations back and forth.

That is a fair argument. The only problem is if I merge it, the original post becomes the first post since it has an earlier time stamp. That could be confusing.

I checked my Profiles.xml and core voltage says 850 = 0.850v but gpu-z and msi ab is showing 0.805v. I am trying to up my voltages to fix my GSOD problem
