Hey all,
How safe is it if I apply 100 voltage in Precision X1 when overclocking? It won't kill the GPU would it? Also will it cause damage to the GPU if I run a OC setting 24/7 with some voltage applied? My PC never really shuts off so if I apply a OC setting, it'll stay on for awhile. I can't remember where I read it, but I heard adding voltages to Nvidia cards isn't a good idea. Not sure if it's true, that's why I'm hoping someone here can help me out :)
 
Thank you.

Did you apply voltage to your GPU in X1? Without adding voltage to the GPU, I can get +81. Well that's what X1 says when I do a scan.

Is heaven good for GPU testing?

Use 4K settings
 
You can see some of my results in my build log - links in signature RTX Project
 

I got Timespy extreme. Is that better than Fire Strike?

Any benchmark that can load the system consistently will work
 
Measure - adjust - measure

Did some quick testing in Heaven. It seems all I can get is +140 on GPU clock. At +150, Heaven shows some crazy large blue star like flickering all over the screen. I assume that's artifacts? Got the memory clock set to +750. Going to now test in Time Spy Extreme. Will report back with results :)

#14 if I remember correctly
 
All benchmarks are synthetic - OC stability from benchmark to benchmark & to Games is not always equal
 
Sounds like your close to the edge - need more testing
 
What is the Max MHz without ANY OC ---> just sliders for Power & Temp Targets full right ?

I believe it's 1950mhz stock. When I raise the GPU to +130, I'm getting something like 2080 or 2070mhz. I got the voltage slider set to 40, and it seems fine. Is it safe to play games and leave the video card with the voltage at 40 when the computer is sitting idle? Or should I just revert it back to default settings after gaming? If all I'm getting is a few extra fps when overclocking, maybe leaving the OC settings on all the time is useless lol?

All the voltage slider does is allow boost 4.0 to use higher voltages if you are not being power limited. Stock voltage will go up to 1.068v and with the slider at 100%, it will “allow” up to 1.093v if not hitting power limits. The power limit (with slider at 130%) on the 2080 XC Ultra’s is I believe 325 watts. You will run into that limit pretty quick and will clock down depending on game and what resolution you play and temps.

Honestly, like you said, for the extra 100-200mhz OC, you may see 5-10 FPS increase depending on game I’m guessing... up to your setup if it can handle the extra power draw and heat.

Ahh I see! So basically Nvidia made it where you can't overvoltage the GPU? Well that's what I'm gathering from what you said :) I'll keep it on default settings and only change it when I benchmark. My system should be fine for overclocking. I got the i9 9900k, 16gb ram and this RTX 2080. I've yet to attempt overclocking my i9 lol. Sort of scared to be honest. The thing is a toasty CPU lol.

Yea Nvidia put a hard voltage cap at 1.093v. Only way around that is extreme cooling and custom bios that we “normal” people can’t have... 🤪

LoL yea the 9900k can get warm... going to Delid mine soon and direct die cool it just cause I guess 😎 I have mine at 5.0ghz @1.28v under load and I see a couple cores in the low 80*c range...
