Solving Overclocking GPU RTX 2060 Mobile [Laptop]
Solving Overclocking GPU RTX 2060 Mobile [Laptop]
I have an Asus Zephirus M, RTX2060, 16GB RAM, I7 9750H.
I successfully undervolted my CPU using ThrottleStop.
But I attempt to overclock the GPU with MSI Afterburner.
Current settings:
Core voltage: No change
Power Limit: No change
Temp Limit: No change
Core Clock: +155 MHz
Memory Clock: +300 MHz
Fan speed: No change.
(I already notice a slight performance boost)
Questions:
First, can the Core Voltage, Power Limit, Temp Limit, and Fan speed be adjusted? Are these settings fixed because I’m using a laptop, or should I find a way to modify them? If so, what voltage increases are recommended?
Second, the fan speed is managed by another application (Armoury Crate) and is set to TURBO for higher performance during games.
Is TURBO mode suitable for improving cooling or performance while gaming? Can I lower the power settings instead? (The noise isn’t bothersome.)
Third, what are the optimal voltages for Core Clock and Memory Clock? Please note these aren’t locked, so I’m increasing them to 155 MHz and 300 MHz.
Thank you for your assistance in finding the ideal configuration to maximize performance while maintaining system stability.
Afterburner's OC Scanner consistently shows 90% confidence. I tried it several times, but eventually stopped using it since the suggested core clocks were too strong. It worked for 8-hour runs of Asus Realbench, but not so much otherwise.
I don't have a big collection of games—just noticed the OC would crash in UE4 titles, and lowering the core clock helped.
It could potentially do the opposite. On auto settings, these CPUs usually start with higher voltage than...
Keep it quiet. It's not worth trying on laptops.
Since the CPU and GPU share the same cooler, keeping the GPU cooler will help offset any CPU overclocking you've applied.
1) They're restricted to protect the manufacturer.
2) A cooler GPU runs better. It has a low 80w power cap.
3) It's already locked in place.
In fact, I was only able to adjust the Core Voltage and Memory Clock. The settings for the Core Clock were increased to 155Mhz and the Memory Clock to 300 Mhz. This change already resulted in a slight improvement in FPS, and the GPU temperature during gaming is at 79*.
The adjustments were made based on evaluating power and heat capacity. The goal was to ensure optimal cooling performance.
Afterburner's OC Scanner consistently reports 90% confidence. I tried it several times, but eventually stopped using it due to overly aggressive core clock settings. It handled 8-hour runs on Asus Realbench well, whereas games behaved differently.
I don’t have a big collection of games, but I noticed the OC would fail in UE4 titles. Reducing the core clock resolved that issue.
It could work the opposite way too. On auto settings, these CPUs start with higher voltage than needed, which often forces owners to undervolt them for stability. The makers do this to ensure advertised performance.
This is partly due to silicon variability. Since there’s no universal setting that fits every CPU, it’s hard to find a one-size-fits-all solution.
Unlike Nvidia GPUs, Intel CPUs don’t automatically adjust voltage for maximum frequency unless they hit thermal limits. They can run at 95°C or 100°C and still hit 4.0GHz across all six cores.
Not ideal for long-term CPU health, but that’s just an example.
The 2060 will gradually lower its frequency by about 10°C per throttle point, though I don’t know the exact limits for these GPUs.
I've increased the core clocks to +205mhz and the memory clock to nearly 500, and I haven't experienced any crashes.
The GPU boost 3.0 allows the GPU to reach higher frequencies when they're below the throttle temperature, which confirms the overclocking is effective.
