Worth Overclocking 1080ti
Worth Overclocking 1080ti
Hi everyone, I understand this might already be discussed, but I wanted to give a quick heads up beforehand. I own a 1080ti sc and am wondering if overclocking is really necessary. What performance boost can I realistically expect? Since every card behaves differently, I don’t anticipate a precise number. I also have an i7 7700 with 16GB RAM, but most people would agree extra 1fps is nice! 😊
All GTX108Ti models will perform similarly in terms of overclocking, delivering comparable results. The main variation between manufacturers lies in the components used for power delivery, cooling, and overall card design. Choosing specific GPU chips is no longer a priority.
If you plan to overclock, ensure your airflow is sufficient. For watercooling, verify you have adequate cooling capacity to handle the GPU's heat.

Free boost with minimal risk, why not?
Around 10%. Varies by game or software.
Well, I think it's not really worthwhile. AIB makers produce their chips, which explains why you'll find several cards with identical chips from each manufacturer. They tend to use the best chips on their most costly cards. Also, newer cards often have turbo boost, and many exceed the advertised clock speed. For instance, my GTX1070 is labeled as 1600 MHz, but it consistently runs above 2000 MHz without any overclocking.
Sorry, I'm running a bit late to the gathering, but I have some ideas about boosting the 1080ti's performance.
Zebarjadi's approach is quite accurate. What others often overlook is GDDR5 errors and its error correction features.
GDDR5 can fix numerous issues before you notice artifacts, yet it still maintains stability, though at the cost of performance.
Additionally, GDDR5 exhibits a repeating pattern in overclocking, as illustrated in the graph here:

(Some believe this is linked to loosened memory timings)
Avoid using Unigine. Instead, try MSI Afterburner's Kombustor, which must be downloaded separately. (For final stability checks, stick with Unigine and similar tools.)
In Kombustor, you can monitor the number of artifacts displayed via a counter on the screen—this usually represents error correction in action. These errors are typically hidden until memory overclocks cause problems. You’ll also notice a real-time drop in frame rate when artifacts appear (even if they aren’t obvious dots or lines).
Kombustor provides a static benchmark, keeping frame rates steady because the scene remains consistent.
You can also use Kombuster to adjust memory overclocks in 1mhz increments in real time, helping you identify the optimal peak for maximum performance. Activate the on-screen display and observe how the frame rate changes with each setting.
Just ensure you run Kombuster long enough until your card reaches 80°C before fine-tuning. Save your best settings as profiles so you can quickly switch between candidates.
For 4K, it seems memory performance often outperforms clock speed. I reset the clock to +0 instantly and saw only a minor drop of about 5 frames, whereas returning to default would lose around 20 frames. So prioritize tuning your memory first, then adjust the core clock.
Caution: water-cooled cards can extract significantly more core clock from their overclock.
