I was able to find a sweet spot at 2.55 GHz with my Sparkle Titan Arc A770 16 GB.

2.4 GHz is stock.

Arc Control have limited options regarding Performance Tuning, only GPU Boost (it's a percentage of clock increase), Voltage compensation (only allows positive offset) and power and temp limits.
MSI Afterburner isn't compatible with Intel ARC, it's possible to use Arctic Control, but regarding voltage, you can only set a fixed value.

There's a gal over at hardforum that's been ocing the crap out of her 770 for a couple of months now. She's nearly broken 3.0 with it but I can't remember what methods she's using (volt mods etc). If I can find the thread I'll link it for you.

Sadly, I don't even know if 2.6 is possible with mine. Already saw driver timeouts. The only thing good, was that it didn't make the entire PC crash during my last experiments.
Once again, Superposition 1080p Extreme is very good at finding core instability.

Also, 2.61 GHz had a lower score than 2.55 GHz.

She isn't messing around, I won't say anything else so as not to ruin anything for you.

Looks like the "GPU Core Power Limit" could actually be TBP! That seems to explain why I got the best Superposition 1080p Extreme benches with the power slider dragged all the way to the max!

i just put my boost to 40 and power to 200w and got 2575 for fun so i think that's the going rate with Arc control , now returned to 160w and 2400. some say if you use the Preditor bifrost app it will go more but i can't be bother to tell the truth im happy with 2400.
