Question Overclocking RTX 2070 Super
Question Overclocking RTX 2070 Super
Hello.
I just bought a new PC and am attempting to overclock my GPU.
Right now I'm using these settings:

So far I haven't completed it.
Could you tell me what the core voltage is? Is it safe to increase it? To what level?
If I change the core clock to 110, the combiner starts failing after 1-2 minutes. Does this relate to core voltages?
I'm also monitoring the memory clock rate.
By the way, the temperature stays under the combiner while the GPU is off, and it's between 27-40°C on the GPU side.
What I did on my RX1080 was raise the temp limit slider to its maximum, which usually unlocks the 110% power limit. This might help prevent crashes when increasing to 110 on the core.
I think my final OC was around +125 cores per 1000 memory. No manual voltage was applied; I just maxed out the temperature and power sliders.
If you need to tweak voltage manually, do so gradually—just like CPU voltage changes. Be careful, as OC settings might not take effect at startup. That way, if something goes wrong, you can simply reboot and start fresh.
From my limited experience, Turing cards perform better in terms of OC compared to previous generations, and adjusting memory has a much bigger impact than core clocks.
From my experience, MSI's OC Scanner isn't very trustworthy, and the results consistently show '90% confidence'—definitely a bug. It also proved too harsh on core clocks; increasing memory to +500 would inflate scan results by 130, 140, or even 160 cores. I tried using Asus Realbench and encountered crashes. Right now, my GPU sits at +100 core with +600 memory, and it consistently passes Realbench. There might still be room for optimization, but I'm pausing to focus on maximizing CPU overclocking. When memory clocks are pushed high, core clocks tend to drop, which is why Pascal and Turing perform better with higher memory overclocks. I'm experimenting further. I increased all three sliders and hope the voltage adjustment on the 0 position will help. My card rarely exceeds 62°C, so the voltage seems acceptable. You're right—Turing feels like a refreshed Pascal, which might explain why the 20-series launch didn't impress much.
You began with a memory overclock of +1000 during auto oc mode. That was a poor decision. Just set the power limit to maximum; you won’t reach the thermal ceiling without proper cooling. The vRAM will begin to fail when you push it further. It remains stable in most games, but problems arise when using Control or Metro Exodus. It’s wiser to adjust the core first.
It seems like you're recalling a situation where not adjusting the thermal slider prevents changing the power slider. You usually set both to their maximum values and then proceed.
