So I'm just starting out, but I've managed to find good clock speeds before changing the voltage. What's puzzling me is that some people suggest overclocking the core as much as possible first and then the VRAM... But if you do that, won't you be using all the power because you're pushing the core to its limits? Or is the VRAM powered separately from the core? It's a simple question, but I'm not very clear on it, so I'll try my best.

They have distinct sections within the VRMs, which explains why you might hear references to 6+2 phases. However, beyond that, the factors restricting your ability to overclock the GPU or VRAM are typically related to power availability rather than being limited by the VRMs themselves. You won't run out of power when overclocking the GPU, and similarly, there isn't usually extra capacity for VRAM overclocking.
