rmation on techniques for GPU overclocking
Hi everyone, just began experimenting with overclocking using a new Aorus 1080ti xtreme edition. Seeking feedback on my approach and some thoughts on the outcomes so far.
I started with a +0 mem clock, +0 GPU glock, and set the power limit to 100 in afterburner. My overall Firestrike score came close to 23000. I gradually increased the GPU clock until it reached around +60, after which performance dropped noticeably. Then I increased the power limit to +150, but Firestrike still lagged throughout and ended up with a score of about 10000. I went back to my original settings and the game kept struggling. Interestingly, the clock remained stuck near 1950MHz, while the actual temperature peaked at 55—unusual since it usually climbs closer to 70 during Firestrike. Eventually, I had to restart the PC for it to run normally again. Was this due to a driver issue?
After a restart, I increased the clock back to +60 and the power limit to 150. This time the game ran smoothly but scored 22000, which is about 1000 points lower than my usual result at +0 clock and 100 power. Is this typical when pushing the limits of an OC? Scores tend to decline as you approach the maximum.
To be honest, I’m new to all this despite having been gaming for 15 years. Any advice on the right methodology would be really helpful. Thanks!

You're aware that xtreme edition is a modified factory version. Increasing core speed and VRAM causes the VRM to draw more power, leading to overheating beyond its limits, which triggers automatic throttling. I recommend maximizing airflow—adding cooler airflow for the cooler fan. Researching with the keyword "cheating GPU power target" (expert only) might help. If that doesn't work, you could try an EKWB waterblock (liquid or LN2).
you are aware that xtreme edition is already a modified factory model, so increasing core speed and VRAM usage causes the VRM to draw more power, which leads to overheating beyond its safe limits. this would result in automatic throttling of performance. i recommend maximizing airflow (adding extra cooler airflow for the cooler fan), and searching with the keyword "cheating GPU power target" (expert only). if that doesn't work, you might want to consider an EKWB waterblock (liquid or LN2).
thanks for reading, i wanted to clarify. i plan to use the pre-baked Aorus gaming mode while gaming. at this stage i'm just enjoying my new setup. i'm aiming for as close to a 25000 firestrike score as possible. since i haven't really tried this before, i'm unsure what the different symptoms mean. i've heard people mention their drivers crashing during tests, wondering if that happened when i was getting around 10000 scores regardless of adjustments until rebooting.
so far i've managed +25 core clock, +220 mem clock, +20 power target. i'm settling at 1987MHz during firestrike. maybe it's a sign—it's the year i was born. 😛
edit: i've noticed the cooler actually performs well, rarely exceeding 70c during firestrike with my current settings, and that's thanks to the fan curve not just running at full speed
It was possible, you can skip the restart by turning on and off the GPU in the device manager, which is something I usually do.
Likely there’s a constraint involved? Install GPU-Z, open it and check the last sensor tab, then search for PerfCap Reason.
vRel shows reliability, meaning performance depends on voltage stability.
VOp reflects operating limits, such as maximum voltage.
Pwr indicates total power restrictions.
Thrm points to temperature constraints.
Util highlights GPU usage limits.
The 20000 to 30000 score corresponds to Titan Xp in a strong CPU+RAM+storage setup. The 23000 indicates it surpasses other GTX 1080 Ti models, reflecting more frames for gaming. Aorus stated your model was hand-selected for better optimization (gauntlet?). For reference, EVGA offered K|NGP|N with a trident BIOS profile, and you can adjust each setting individually just like in game mode.
Yes, it was possible to skip the restart by turning the GPU on and off in the device manager, as I usually do. This seems to be a restriction. It appears there are limits based on something like the GPU-Z tool—downloading it, checking the last sensor tab, and finding specific values such as PerfCap Reason. The performance is constrained by various factors including voltage reliability, operating voltage, power limits, temperature, and utilization. I didn’t realize that was a feature of GPUZ, so thank you for sharing that helpful information. Eventually, I reached a maximum of 24,500 and won’t be able to go higher from here.
