I'm trying to figure out if I need a new PSU or if I just need to raise the voltage for my current GPU Curve. I currently have a Corsair HX1050 running since 2014. Seems to be about 7 years now.

I've been gaming with no issues since I got my 1080 Ti a couple years ago at .900v @ 1911 Mhz. At full power, my card's able to easily run at 2050-2076 MHZ when pushed to the limits, but I don't do that much (only playing games I hover close to the 60 fps mark). I'm running a Corsair Hydro Cooler so temps are between 30-35c Max.

I'm getting display driver crashes within an hour or two after mining set to 75% Power. I upped voltage to .950v @ 1911 and got a displaydriver crash around 8 hours later. Now I'm running fully stock (stock voltage, power, core clocks) temps no higher than 35c with no issues at all. This is obviously not a viable solution as the GPU is pushing over 200w now. Also, I don't see stock voltage being necessary for stock clocks with my GPU temperatures.

I am fully stable at .850v @ 1823 Mhz however. Some nice low wattage there. I feel like I just really wanted to run around 1911 Mhz.

a) (the long shot) Are my power supply voltages loosened now due to age, and the GPU requiring more voltage now than my tightened/fine tuned undervolt? For instance, could a slight ripple/hitch in voltage crash a display driver if undervolted fine-tuned, as opposed to a slight ripple/hitch at fully stock?

b) Does my GPU just require more voltage for 24/7 usage? I suppose when I game, I don't game for more than a couple hours a day.

I'm unsure if I should continue bumping up my undervolt voltage, say to maybe .975v, or if I should look somewhere else. I feel like .975v is a lot for 1911mhz liquid cooled, then again I see people getting different numbers everywhere depending on chip samples.

Any recommendations would be helpful on what to try next.

Edit:
My hash rates are for DaggerHashimoto

41.410 mh/s 80% PWR 1823 mhz .850v
43.995 mh/s 80% PWR 1911 mhz .900 or .950v (unstable)
44.25 mh/s Fully Stock
45.900 mh/s 80% PWR 2050 mhz 1.012v (untested for stability, but the bump over .850 could be worth it if the voltage holds at 1.012v)

In my experience, gaming generally needs considerably more voltage than mining.

However, mining is extremely memory dependent, and memory is where I'd look first for mining stability issues.

Thanks. This was the problem. It ended up being Memory tweak intensity settings. Dropped it down one notch and issue is resolved!
