I'll say it again, first check your temps. If you're still using MSI's default fan curve, which you probably are, you are most likely running hot. So in Afterburner go to settings and set a custom fan curve.

Having said that, why would you set your voltage to +100mV if there is no need? Do it in small steps. Increasing voltage a lot will lead to higher temperatures and noise levels and shorter component life. If you want to achieve a certain overclock and you need +100mV then yes, you should set it that high, but I highly doubt 1120MHz needs that much voltage. As I said, I think it's more likely a memory issue. Ignoring the fact that you should overclock your memory and core independently (Which you really should be doing, by the way, to know what exactly is causing issues), try setting aux voltage to +25mV or +50mV. Going above +50mV isn't advised by people who know more than I do, so I follow their recommendations. You may also want to go higher or lower with your memory speed to try the different timing straps, but let's not complicate things further.

I say dial back your memory to 1500MHz, overclock your core and then start messing with the mem clocks. Good luck!

To make things clear, the black screen you are seeing, does the display go back when you unplug - replug the monitor cable?

If it doesn't, it's a card issue. If the display goes back, it's a known issue on these cards. Which BIOS do you use?

Aux Voltage has VERY little to do with that. Memory Voltage is somewhat linked to the Core Voltage. Try to increase the core Voltage and try it again. Else, 1625 is the way to go.

Or, BIOS Editting to allow you to use tighter timings for higher memory clocks.

Same as above. Try a higher Core Voltage.

But when I started playing Witcher 3, ive noticed minimal artifacts, so does this mean my oc is not stable? Should I put my core voltage higher? Is it safe to put it at 100?

If your cooling allows it...

That is for you to figure out. What case, Fans, etc you have. thumb.gif

I have not tried that, will try it immediatly.
I just use the stock asus bios smile.gif

SAGE! Great advise.

Bottom line, it's all about the cooling.

At least I can get 1075 / 1550Mhz stable without adding any voltage. I'm happy with that.

Make sure to uncheck the little light at the bottom of MSI AB so when it reboots it won't set the same sets you had that made you crash. It will load default sets on startup. This allows you to not get caught with your pants down after reboot. Just an FYI to help in the future when you are benching. thumb.gif

@mus1mus, after deleting asus gpu tweak 2 it's actually stable now...haven't had the black screens anymore so far. Will keep updating with proof pic of card and stuff so i to can join the grid on page nr1 smile.gif

hello guys i found a great deal on the Powercolor 390 PCS+ for 310EUR, i might be getting it, does anyone of you have it? whats your opinion?

any signs of coil whine? does it have 0dB on low temp?

I have it. No Coil Whine. Silent all in all, yet it is absolutely quiet under 61 degrees.

Mine is not a great overcklocker though. Else all else in it is great.

It's been a while since I was last active on this thread or the forum, but I've since bought a second 390X for crossfire and did this today biggrin.gif
