[Official] AMD Radeon HD 7950/7970/7990 Owners Thread - Page 84

post #831 of 38701
Yeah but even @ stock volts I am dropping right down to around 1.14v at times meaning I cant get anything higher than 1020mhz core without issues.

I am going to try changing my PCIE cables and then changing to the other bios to see if that works.

Ill monitor that voltage line and see what happens.

Might RMA the card otherwise.

I would just like to note that most of the time the set voltage is what is monitored.
With the 7970, it displays the actual voltage instead of the set voltage.
In other words the vdrop is normal. wink.gif

yeah but I am dropping to below 1.14v which is well below stock voltage no matte WHAT voltage I set....

Ill set my voltage at 1.3v on the core and take a screen shot of the graph to show you how much it drops when under load.

That's normal.
You could change a setting that puts the program to default voltage monitoring (set voltage monitoring) and the "problem" will disappear.

I managed to push my xfx 7970 (core edition) to about 1080 mhz, where it starts to make these lines, dots, blinking things when I play or use furmark.

Should I expect higher clocks? or is this acceptable?

I also wonder how I can higher the voltage, and can this help me reach higher stable clocks? (using afterburner 2.2, but cant make it work, it just reset volt at once)

thats correct! it has nothing to do with the displayed voltage on idle. Its to do with the fact that no matter what voltage is set I am drooping more than .5v which is a massive amount!!

Thing is, even if I max out the voltage slider to 1.3v in afterburner my card is drooping to 1.23v on load.

I just did the first benchmark in 3dmark 11 and then pressed escape when running at 1.3v maxed out slider on AB. My voltage in that short amount of time dipped to 1.216v....

That is just shocking!
