How was the 980 Ti SC+ overclocking going?
I didn't want to push too much, but moving past this point led to serious instability. I faced issues with the +mv offset and wasn't sure how to proceed for further overclocking. I'm fine with the current setup but need to understand what went wrong. Initially, I tried +150, +400, and max mv, which was very unstable and caused crashes. I reduced it to no mv offset but still faced problems, so I lowered it to +100 core, +250 mem, +0 mv, 110% and increased gradually. How can I achieve more stability at higher clock speeds? My target was 1450mhz core and 4000mhz memory.
You need higher voltage, but keep in mind not everyone will achieve the same outcomes. Variations in silicon manufacturing, temperature conditions, and other factors play a role. My initial reference is a solid starting point for your goals. Otherwise, you should be able to reach your objectives under similar conditions. The default memory clock is 1750, so begin increasing it to around 200Mhz for a solid jump to about 1950MHz or 7800MHz effective. When you're overclocking, establish a solid baseline and then gradually increase in small steps, adjusting voltage needs while keeping an eye on GPU temperatures during testing. The same applies to the core.
Uncertain about the origin of that 4000MHz memory figure, as the factory default is 1750MHz (with an effective 7000MHz). Also, I'm assuming you're talking about a boost speed of 1450MHz on the core, not the base core speed.
In any case, I usually check other reviews of the same card to see what others experienced, like these links:

For some reason, when I run hwinfo and RTSS, my memory speed seems doubled, so I’m targeting 2000mhz. Also, I should have mentioned the 1450 boost speed earlier. My mistake on both those points.

You require higher voltage, but keep in mind not everyone will achieve the same outcomes. Variations in silicon manufacturing, ambient temperatures, and other factors play a role. My first link provides a solid reference for your goals. Otherwise, I believe you should be able to reach your targets under similar conditions. The default memory clock is 1750, so begin increasing it to around 200Mhz for a solid start at 1950GHz, or aim for 7800GHz effective. During overclocking, establish a solid baseline and adjust gradually, balancing voltage needs while keeping an eye on GPU temperatures during testing. The same applies to the core.
Thanks for your guidance, after reviewing those resources I noticed my overclock performed well and my initial targets were overly ambitious. My main aim was a stable effective overclock without damaging the card, and it seems I achieved that.
Following your advice about voltage, I increased it slightly and will conduct some stability checks to confirm everything is aligned.
Welcome! The process of boosting performance (GPU or CPU) is starting slowly and steadily, aiming for peak speed without crashes during a race between performance and power. Artifacts in stress tests, like Furmark numbers, may appear as snow, but they don’t cause failures—this indicates you’re still within the optimal range or voltage levels. There are just guidelines, as outcomes will vary from person to person. Good luck!
