I'm experiencing 2fps to 4fps renders with CUDA on a 980, hitting the limit of my memory speed without exceeding 1GB of VRAM. My core utilization is about 66%. Should I consider overclocking my memory? If yes, how would you recommend overclocking it for this card? Please no comments about using a GeForce card for GPU compute.

Hey, at BEST you can only get a time reduction equal to the percentage you overclock. For example, if you spend 100 minutes rendering and boost your GPU or video memory by 10%, you might save about 10 minutes. (This is highly unlikely to occur).
In practice, your main bottleneck could actually be on the CPU side.
The benchmarks I’ve seen usually show improvement with a GEFORCE card, but returns drop quickly with better cards, suggesting most issues are related to CPU performance.

The simplest method to boost any part of your graphics card is by using Afterburner. Just increase the memory clock. It functions as a slider and operates with an offset. For example, setting it to 100MHz will add that amount to the standard speed of your card's memory.

The benchmarks I've seen usually show improvement with a GEFORCE card, but returns tend to fade quickly as better cards are used, suggesting most performance gains come from the CPU.

I've seen reports suggesting that overloading VRAM memory during overclocking might reduce performance because it raises the chance of read/write errors. It's recommended to make minor adjustments and check after each one.
