post #1 of 4
Thread Starter 
I have unlocked the clock limits in MSI AB.

Voltage control is unlocked.

Here are my settings.

Core voltage 1.3
Memory voltage 1.65
Core clock 1200 mhz
Memory clock 1575 mhz

I run 3dmark11 and my system reboots instanly(right before graphics test 1 is about to start).

Cards are 80 and 86 % asic quality.

Im running the 12.3 drivers as well.

Is it not stable at these settings? Also what are you using for cooling, running 1.3v is really charging your cards and should create quite a bit of heat.

They are under water, so temps are not an issue.They reach 42 degrees under gaming load.

Have you tried less voltage? Maybe drop it to 1.25v and 1180mhz and see if it passes and then slowly work you way up.

I'd start at 1.2v, and see what you get in mhz on the core without corruption, then 1.25v and see where you get. Sometimes the cards just won't go any farther after a point, regardless of voltage.
