Is overclocking via Wattman safe If temperatures are kept in check?

I heard it should be safe because AMD allowed max voltages to be in safe range (1.2V max for my RX580), but I'm interested in your opinions.

For example when I play demanding games, my Sapphire RX 580 Nitro+ is already running at 1.2V with default (auto) settings.

But what about memory voltage? I noticed in Wattman that my stock memory voltage is 850mV, and it can go up to 1.2V. Would 1.2V still be safe (it sounds like a huge increase to me, and hard to say how high the voltage would go on auto if i overclocked the VRAM)? All the temperature monitoring programs I've tested only report GPU core temperatures and voltages. I'm worried the VRAM could get too hot, or maybe even some VRMs.

And is overclocking VRAM and changing its timings without adding too much voltage safe?
