Can I continue overclocking my GPU while keeping its voltage and power limits in place?
Can I continue overclocking my GPU while keeping its voltage and power limits in place?
Hello,
Details:
CPU: Ryzen 5 3600
GPU: Gigabyte GTX 950 OC Edition (Not overclocked by me, it is stock)
Using MSI Afterburner OSB and HWINFO64, I observe performance limit power & voltage settings.
My GPU reaches maximum even beyond the specs shown in GPU-Z (refer to image below). GPU-Z reports a boost of 1241 Mhz, but in practice it caps at 1352 Mhz. Is this the OEM OC I see? If yes, why isn’t it displayed by GPU-Z?
My GPU is operating at 97%+ utilization during benchmarks and games.
Questions:
1. If I plan to overclock my GPU in the future (due to uncertainty about power & voltage limits), can I still reach or exceed 1352 Mhz, or will it be capped by these limits?
2. If indeed the limits are restricting any future OC, should I attempt to increase them, and if so, by how much?
Thank you in advance,
Gpu boost operates based on the minimum speed shown in gpu-z, which is the baseline frequency. Once the GPU has sufficient power and thermal capacity, it can increase its boost further.
Regarding your questions:
1) It’s not guaranteed, this profile is conservative; you might achieve higher clocks even with identical power and thermal constraints.
2) Overclocking a GPU is straightforward, and you can’t damage it beyond its limits because there’s a cap on power usage.
Just adjust the power and temperature boundaries to their maximums, then raise the core clock offset until stability fails, after which set it to the highest stable value. Repeat for memory offset if needed.
No reason to avoid this unless you aim to minimize power use.

Just adjust the power and temperature limits to their maximums, then increase the core clock offset until stability fails, then reset to the highest stable value. Repeat for memory offset if needed.

Great! Just confirming everything is set up correctly before you start.
