Okay so, I'm just wondering if i am hitting the max of my PSU, I have overclocked both my CPU and my GPU, CPU is overclocked to 4.6 and my GPU is overclocked +290 on the core and +200 on the memory, however i have noticed some very strange problems when overclocking my graphics card.
I run MSI Afterburner to overclock but sometimes the HDMI will cut out, you have to unplug it and plug it back in, in order to get the picture back but the weird part is, is that the card doesn't actually throttle like it does with a failed overclock but instead acts like the application simply closed, i know the difference between the two because if i push the GPU further it does crash and the overclock throttles to the reference clock.
The Core Voltage actually decreases the frames per second and lowers the stability of an overclock meaning i can't actually raise it with any benefits
It only affects the GPU so i am not sure if it's actually the GPU that is hitting the max i can overclock it or the PSU hitting the max because i am overclocking the GPU, I just need some advice to see what is going on?
I would say it's only a poor or failing card if you set it to stock clocks and it keeps shutting off the HDMI port. Not a suitable overclocker? Haha, my 980 Ti Hydro Copper (the same as yours but designed for a custom liquid cooling loop) freezes my whole system when I push it too high. My build is brand new and I'm still testing, but I'm at +190 and I definitely won't reach +290. I've already tried +250, which froze within seconds when starting a GPU stress test. For most cards, anything above +150 is considered a solid overclock. You're lucky if you find one that stays stable past +200. My recommendation is to lower your overclock to +200 and see if you can play games for a long time.
Don't lose your PSU, not even when overclocked. Large demand increases should still be managed. Could the GPU memory be the issue? How much did you increase the overclock?
Near +250 MHz the unusual behavior varies across titles, GTA V stands out by remaining stable even when demanding maximum GPU power, whereas games like Tomb Raider tend to be more prone to instability.
Would the GPU be failing or is it simply not suitable for overclocking?
I would say that it's only a bad/dying card if you set it to stock clocks and it continues to shut off the HDMI port.
Not a good overclocker? lol My 980 Ti Hydro Copper (the same card as yours, but made for a custom liquid cooling loop) freezes my system completely if I overclock it too high. My build is brand new and I'm still testing, but I'm at +190 and there's no way in hell I'm going to get anywhere near +290. I already tried +250 and it froze within seconds of starting a GPU stress test.
For most cards, anything over +150 is a "good" overclock. You're very lucky if you get one that is stable above +200.
My advice: Back your overclock down to +200 and try your games. If it works for a long gaming session (2+ hours) involving all of your games, then increase it by 10 and try again. It's very likely that you're simply over your card's stable overclocking limit.
Around +250 MHz the unusual behavior varies between games, GTA V stands out as stable even when demanding maximum GPU power, whereas Tomb Raider tends to be more prone to instability. 200 MHz seems more reasonable for an overclock, so try it and compare. Your memory overclock results?
