Was die Überclockung deines GPUs korrekt durchgeführt?
Initially, please note that this might not be the correct section. I wasn't sure about the best place to post this.
I’ll try my best to clarify the steps I took.
I set the 50% fan speed on MSI Afterburner to avoid any GPU temperature issues.
Core Clock – I raised it from 0 to +25%, ran Heaven Benchmark 4.0, and played through multiple cycles. Each time a crash occurred, I lowered the core clock by +25 until reaching a crash point of +120. Then I reset it to +110 and completed two more benchmark runs without problems.
- After that, I returned the core clock back to 0% to test the memory clock separately.
Starting at +100 on the memory clock, I added another +100 after each successful run. At +600 I crashed, so I removed 50 seconds and crashed again. I reduced by +25 until stable at +500.
I followed these settings:

Memory Clock – I began at +100 and increased by +100 after each successful benchmark. When reaching +600 it crashed, so I adjusted back to +500 without any crashes.

I then reverted both core and memory clocks in MSI Afterburner and completed three benchmark runs smoothly.
Results after benchmarking at default and overclocked:

Now I’m wondering: should I push the core clock up by +1 each time until I crash, to maximize GPU performance, or should I keep it as is?
Additionally, how secure would it be to run benchmarks with stable clocks and let the system idle for a while (for instance, take a shower and restart the benchmark)?
Apologies for this lengthy explanation—I’m new to overclocking my GPU. Will I see noticeable improvements by maintaining the overclock?
It largely depends on your experience and the particular card. If you're sure and maintain strong temperatures during stress, you might consider trying it. But if you're worried, it probably won't significantly boost performance.
The benchmarks aren't the most effective method to assess stability. Consider running something like MSI Kombustor for a longer duration. If it runs smoothly for several minutes, proceed and observe after 20+ minutes, repeating as needed.
The benchmarks aren't the most reliable method for checking stability. Try running MSI Kombustor for a longer time. If it holds after a few minutes, wait and test after 20+ minutes. Once stable, add a bit more and retry. Should I restart from the default 0% or apply the current clocks from Heaven Benchmark? And if it crashes, which component should I fix first—core or memory?
If you believe you're "stable," I suggest playing the usual games for a few days under these conditions. Benchmarks and GPU stress tools aren't always reliable measures of stability. I've pushed my GPU to its limits and maintained stability across 90% of my games and all test software, though a few would still crash.
If after this you notice no unusual behavior—even minor glitches are absent—you might attempt further optimization. But be aware you're nearing the point where gains become minimal. Spending excessive time fine-tuning to extract the last few MHz from your GPU and VRAM often yields little result. Keep in mind that a 10% boost in clock speed (especially for GPU clocks) typically only improves performance by 5–7%, depending on the game. Some titles may gain from higher VRAM speeds, but most see little to no change.
You should likely move the clocks directly over, as it's at least fairly stable under the present settings, which is a positive aspect.
I think I'd lower both by equal amounts until things settle, then gradually bring one back up.
It seems you're likely fine to move the clocks directly, as it's at least stable in the current setup, which is a positive sign. You might want to lower both by equal amounts until stability returns, then gradually increase one at a time.
Regarding your concerns: never touch core voltage, as rumors suggest it could damage your GPU. Also, consider raising the power limit by +10 if needed.
It largely depends on your experience and the particular card. If you're sure and maintain strong temperatures during stress, you might consider trying it. But if you're worried, it probably won't significantly boost performance—just let it stay as is.
The outcome largely depends on your experience and the card in question. If you feel confident and maintain stable temperatures during stress, it might be worth a try. But if you're unsure, performance gains are unlikely to be significant.

This suggests the maximum voltage and power limits are important to consider.
