I don't think so, but i guess its possible if there is a lack of voltage supplied to the core/memory.

I'm running 1100/1250 with +0mV and got a black screen. Hm...
I'll put my core back to stock and see what it's like.

Just put the voltage up +0.006v. Though i suppose it would be better to do it your way initially.
Soldato
Yeah it was stable for almost 2 hours, so that's probably an easier way. It was probably just borderline stable.
No. Unstable RAM and too much voltage can do it though.
Soldato
Yeah I get it when I try putting high volts through it using Trixx. It sucks really as the cooler can handle it.
Kaapstad if your alive make a R9 295x2 official thread
I offered the other day but people said they prefer it if a proper owner does one.
You do it. Never a good idea to have a non owner of a gpu making an owners thread.
If you're running 120hz lowering it to 60hz will give you more headroom before you black screen from overvolting.
Soldato
The card runs at a slightly higher voltage with 120hz (Higher amps too probably), which is enough to trip the blackscreen apparently (Not sure if voltage alone will do it or if its wattage). So lowering refresh rate helps. Measured with multimeter on the voltage checkpoints on my 290x Lightning.

That's pretty strange. I'll give it a try now.

Even with that my card can't handle the volts 
It just starts flickering and becomes unstable.

The difference in volts you can apply is only a couple of millivolts, you cant go full overboard. And if you got flickering then lower your RAM.

Ah that sucks then, It means I'm limited to about +110mV.
I can't get 1200Mhz at +100mV. Bad overclocker compared to my first card.

Glad my Lightning doesnt black screen until about 165mV, and that lets me do up to 1240/1650 at 120hz

That's pretty good. I haven't tried my memory, I don't think it's very good.
I've seen some reference cards at +200mV. I wonder how that is.
my ref 290s have all done 1270-1310 on +200mV at 60hz (Had 3 of them)
What do you mean?
Soldato
Yep seems that way.
