It can be RAM, CPU memory controller, but most likely GPU, GPU mem controller, VRAM, GPU VRM.
If it was Linux, we could easily blame FAHcores, but in windows things are relatively stable on that front.

I upped the GPU voltage by 6mV to 963mV@1801MHz and its been stable for ~50WU over the last few weeks. So apparently my perfectly stable GPU wasn't as perfectly stable as I had thought. Interesting that F@H seems to be more sensitive than any other usage.

It is not sensitive, it is just properly loading your hardware
