Script to find out lowest voltages

[magemaster]

Hello, did any one know if there is or is possible to create a script to find the lowest possibles voltages on a given clock?

I think if easy tune can change voltages on the fly(I read on a review it can), we can log this to a second computer(because at some point the computer will freeze) and with a script lowering voltage from time to time until the system freeze

software oc tuning isnt very good to be honest,even easytune can set the wrong things esp if the cpu is in idle clocks it will set the idle clock speed

best to have some patience and learn the bios and overclock through that,you can either start off with low voltages and raise a little at a time and test for stability or start high and work your way down untill it starts to crash then raise voltages a little

The idea is not OC with software, is just use to software to help me find the lower values possible, for example, to find the lowest possible memory voltage at 1600Mhz, I need to set a voltage in bios, boot, start tests, wait tests to end, reboot, then lower a little more and start over.
with some scripting I can start the script, go to sleep and on the other day see what voltage was the last stable one.

Oc from software is problematic, as some settings needs reboot to apply... maybe can be done too, but I want just some fine tweaking at first.

i suppose you could use easytune for that,another thing is to have memtest86 on a usb stick and adjust memory voltage in bios and test with memtest in dos without booting up

ssd's make life easy with rebooting/testing anyway but i see your point

I did an autoIt script to undervolt the memo, worked very well, but it's still missing log to file, could find out very quicly my memory lowest voltage at 1800Mhz.

Still with a couple bugs, it's not logging to file yet, it uses OCCT and easy tune, and both aren't autoit friendly, so need to do everything using coordinates, I don't if it will work on others resolutions(mine is 1680x1050)
It's my first autoit script in years, so there's lot of room for improvement.

;Auto undervolt script, open easy tune and OCCT before running and 
;make sure there is no window open with the name of the programs(OCCT or EasyTune6 Build 2012.11.21)AutoItSetOption("MouseCoordMode", 0);
$minutes = 5;


if Not WinExists("EasyTune6 Build 2012.11.21") Or Not WinExists("OCCT") Then
   MsgBox(0, "Error","OCCT Or Easy Tune not open");
   Exit
EndIf


WindowExist ("OCCT");
;Cpu Linpack
MouseClick ( "Left", 149, 111);
;Start test
MouseClick ( "Left", 478, 163);

;Advanced   
MouseClick ( "Left", 408, 95);
;Voltage
MouseClick ( "Left", 173, 101);




While 1
   $total = 0;
   For $i = 1 To $minutes*60 Step 1
	  if Not ProcessExists ("linpack_xeon64.exe") Then
		 MsgBox(0,"","linpack stopped");
		 Exit
	  EndIf
	  Sleep(1000);
   Next
   WindowExist("EasyTune6 Build 2012.11.21");

   ;Set button
   MouseClick ( "Left", 275, 515 );
