Safe GPU overclock?

[Drunkaroos]

Hi all. I have recently discovered the wonderful world of overclocking with my MSI r9 270x 4g. I have been experimenting with the clocks in MSI Afterburner, and can get my card stable at around 1160mhz core and 1300 mhz memory. This is with +1% power usage enabled. I cannot get it stable at any higher clocks than I have since the screen turns orange and flickers when I try. Any help to get it stable at say 1200 mhz core and 1400mhz memory?

 

Pic is my afterburner clocks.

Max the power limit and voltage. So long as temps are under 80*C you're good to max everything

How are you testing stability?

[Drunkaroos]

Add more power usage and keep overclocking. Use a benchmark tool like unigene heaven and play some actual games to test the stability of your overclock.

I do. I have been testing it in the Witcher 3 with the clocks above and it is working fine.

How are you testing stability?

The Witcher 3, 3DMark.

Increase the power limit to the MAX. It's not really going to change anything, except limit your OC if it's too low (unlikely, though).

 

Next, if you want to push your card higher, there's only one way: increase voltages. You'll have to unlock it on Afterburner, though. Go into the settings and you should see "unlock voltage control". Check the box and start playing with your voltages.

 

Be careful, though, as you can kill your card if temps get out of control.

Yep, as everyone is saying max the Voltage and watch your temps.

Did some quick testing in Witcher 3. Currently happy +11% power limit, +6 core voltage, 1200 mhz core clock, 1400 mhz memory clock.

The card wont let you turn up the voltage too high on the stock bios, so give that a shot, and see if it increases stability.

 

Also you dont have to be conservative with the power limit. Just max it, because all that's doing is removing artificially set power limits that may reduce the card's overclocking potential.
