Settings for Palit GeForce gtx 770 OC overclocking
Hi there! I purchased this card nine months ago and I'm eager to try overclocking it. I used MSI Afterburner to adjust the settings, increasing the core clock to +70, the memory clock to +395, and running a Valley benchmark for 30 minutes which passed. I didn't alter the voltage settings, set the max temperature to 87°C, or modify the fan curve. My concerns are: is this overclock stable and safe for my card? Will it affect the GPU's lifespan? Could this damage my card?
I possess 670 windforce and am confident your GTX 770 maintains a voltage of 1.175v. You can release the BIOS settings to achieve 1.212v, which remains a safe voltage provided your cooling system functions properly.
Increasing core or memory clock speeds won’t shorten your GPU’s lifespan, though excessive heat will. Doing so above 1.212v without adequate cooling could harm it, or pushing beyond 1.25v even with good cooling might reduce its life.
My GTX 670 may begin downclocking at around 70°C, so keep it below that threshold to avoid thermal throttling and potential damage to your OC module.
Adjust your fan speed to operate at 100% at temperatures between 65-68°C. Determine how far you can push the power limit slider—this mainly involves restricting maximum TDP, which is safe as long as your power supply supports it.

Increasing the core or memory clock won’t harm the GPU’s longevity, though overheating will. Doing so above 1.212v without adequate cooling could shorten its life, especially if you exceed 1.212v with insufficient cooling or push it higher than 1.25v even with good cooling.

Adjust your fan speed to operate at full capacity between 65-68°C. Determine how far you can push the power limit slider—this mainly affects maximum TDP limits, which are safe unless your PSU isn’t up to the task.
Currently I’m at +175 core and +825 memory, consuming 137% of the maximum power rating during peak stress testing.
this is on air cooling gigabyte windforce 3x stock and im hitting max 65c in games with this overclock and 69-70c in furmark. This is with 1.212v unlocked bios
You should look for cheap aftermarket cooler for it if its not enough, liquid cooling too expensive for so old card like these
I have 670 windforce and I’m sure your GTX 770 is set to a stable voltage of 1.175v. You can unlock the BIOS to reach 1.212v, which remains a safe voltage as long as your cooling system works properly. Adding core or memory clock won’t shorten your GPU’s lifespan, though overheating will. Going above 1.212v without adequate cooling could harm it, and exceeding 1.25v even with good cooling might reduce its life. My GTX 670 is already downclocking at 70°C, so staying below 70°C is crucial to avoid thermal throttling. Adjust your fan settings so it runs at full speed between 65-68°C, and set the power limit slider as high as possible—this only needs to cap maximum TDP, which is safe if your PSU can handle it. I’m currently at +175 core and +825 memory, consuming 137% of the maximum power limit during stress tests. My highest recorded temperature was around 75°C in a benchmark, but in games like NFS Payback or Fortnite I’m managing between 65-70°C. Is that acceptable? As I mentioned, I changed the fan curve to higher values and feel confident with this overclock.
When it reaches 70c it throttles for the first time. You can disable this by modifying the BIOS, but I won’t recommend doing it right away. The best approach would be to disassemble the graphics card and apply high-quality thermal paste such as NT-H1 or GC gelid extreme, while cleaning all fans thoroughly. This should likely reduce your temperatures by 5-10 degrees, even. After that, you could push it overclock even further.
Just try to keep it at a maximum of 68c during gaming, which would require fans to run at 100% at temperatures between 65-67c. And as I mentioned earlier, set the power limit to 112% or whatever is available, since with the modified BIOS I’m using it at 200%.
