How to: Bench MSI Lightning GTX-580 for dummies
Everyone has their own way to do things but this is what has worked for me. This is how I bench heaven...



1.Cool to -50c idle in windows
2.Glaze your pot
3.Start benching at stock speed and volts except memory bump +175v ish
4.Slowly cool down pot while benching to -135c (if you hear a loud crack start over and heat back up to -50c.)
5.While at -135c you can set temps and volts while idling in OS 1450/1400 = +449mv Core +200mv Mem +000mv AUX
6.Pull down pot to -150c and start bench..you want to hit -160c by end of loading screen.
7.Slowly pull down to -180c during the first 2 or 3 subtest in heaven and just splash the pot enough to keep it there, do not fill up the pot (thats when I get cracking I believe)
8.Lighten up on your pouring for Test 25-26, let it warm back up to -170c by the end of 26.
9.Once the test is finished do not do anything until you pull back up to -140c or you will freeze when opening GPUZ (you want to be back around -140c anyway so you can apply clocks again for your next run)

***Dont apply clocks with temps colder then -145c***
***Dont Open GPUZ with temps colder then -145c***

-Device lost error = more vGPU or more Cold
-Test 20 freezing = more vGPU
-TIM is very important
-No secrets/

Its seems a function of OCP is occuring at 1470/1400, causes voltage to drop to 0.300vGPU and will stay that way till power is cut at PSU.







Hope this helps
