Please provide the links man for proof, I'd like to see that's an epic clock!
I cat get anywhere near these scores, in Firestrike Extreme my GPU clock is at 2673 with Toxic Boost enabled!Toxic brethren unite!
Nice Timespy score @nordskov
Here are my best Timespy Extreme, Firestrike Extreme and Ultra scores I managed with my 6900 XT Toxic Extreme.

I've not run Timespy/Firestrike since those scores were posted, tend to just play games now.

Matt was pushing 400w+ for those numbers. Using more power tool to hack the windows reg and allow the power limits to be entered way beyond what even the Toxic bios allows. Fun for some 3dMark numbers but not really 24/7 stuff.
I sort of get that, but i would at least like to hit the 2730 toxic boost limit?
Caporegime
Yes I was running over 2900 Mhz core clock under load and power limit was at 500W from memory.
For gaming I run 2800Mhz core clock, 400W power limit at a stock voltage at 1.2v.

What's it read up in the Performance/Tuning, GPU tuning tab for Max Frequency?
Caporegime
Do you definitely have a Toxic Extreme Edition? Because there are around four variants now and only one of them is the Extreme.
The others all have a lower max Toxic boost frequency which is around about what you are getting.
In Adrenaline? I've set it to 2750. Tbh I just want to see the advertised speeds
Definitely the Extreme, Everything says so?

Setting it at 2750 will never get you 2730MHz. It normally falls around 50MHz short of what is set.

Quoted 430W TDP awch! It better do 2730MHz for all that extra power.

So I went 2780 and got 2741. Only upping the max frequency, nothing else. I'm a bit disappointed that the one click Toxic boost wouldn't deliver that though. Any tips on a sweet spot?
Caporegime
It should deliver a peak of 2730, not sustained.

Maxes out about 350/360W iirc (that's at +15 PL)
LttMatt Nice scores just a tiny hair above mine 
. What boost did u manage and how much volt ? For this i did 500w peak and 1.287v and set coreclock to 2885 (around 2820 avg) firestrike was a bit higher (2972) and about 2920 or so avg.
Its a beast of a card. My bro Got 6900xt from Asus strix also xtxh. But at same coreclock and memory clock volt and everything like me he g’ets like 500 less score

I used more powertool and repasted with liquid metal. Brought temps (junction) from insane 88c to 64 and from there i just put higher watt limit with mpt. And lastet upped voltage a tiny bit. From 1.2 Max to 1.287v. That gives stable speeds Way higher. And for gaming its not even getting hot. But boost is up around 2880-2930 MHz stable no dips below 2880
edit.
If i go 1.3v im able to game at almost 3ghz. Still not getting hot. But dont like that much voltage for everyday gaming. Those results i managed is my everyday game profile I could proberbly do higher scores but dont really Care about it. All i Care about is stability and really High boost for even better gaming experience. And since temps and everything is fine im settled

One thing is for sure, whoever buys your Toxic after you is gonna get one HELL of a dog of a card 
I'm only using stock paste, seems like a toggling war between adrenaline and Trixx, each one overrides the other. Just upping the power with toxic boost enabled lets me hit the 2730. No other changes neededAsh79.

Look fine, tweaking the voltage and clocks can save you power and then heat if you are looking to not go bankrupt at 28p+ KWh lol.
I'll run some numbers when i have an hour spare. My sweetspot and efficent settings are:
2499/2599 @ 1060mv, +15% (293w limit) 2122Mhz vram. My waterblock goes a long way to help though.
