Your card is specially binned by AMD "Navi 21" XTXH silicon mated to a much more capable power section.So as I have posted in it's own thread, I got the new badass XFX Speedster Zero WB Radeon RX 6900 XT that ships with an EK Waterblock preinstalled.
So, I haven't started overclocking yet, but I already but I figured I'd post my baseline runs here.
I flashed my BIOS to allow for Resizeable BAR / SAM support, and decided to run a Timespy with everything at stock settings, and well, it was BAD.

Then I remembered what some people said above about how Timespy REALLY doesn't like SMT on the Zen2 Threadrippers, so I tried disabling SMT and trying again.

Now, keep in mind. These are out of box numbers. No overclocking, no tweaking, no lowering voltage, no increasing power limit.
I feel like an over 22k graphics score out of the box without overclocking is almost too good to be true?
So, a few questions.
1.) Is this too good to be true? Could something be off? it is suspicious that my out of box results are above some of your max ovcerclock scores, especially since the core clock seems to be running at about the same ~2500mhz. I appreciate any thoughts.
2.) This thing runs hot. Like not "air cooler" hot, but much hotter than my old Pascal Titan X under water. For these runs I set the fan profiles to keep the coolant at ~33C. On my Pascal Titan X this resulted in in game temps of about 38C core temp. This beast is hovering at about 50C to 51C. Part of this is not unexpected. The Pascal Titan was a 250W TDP card. The 6900XT stock is 300W, but who knows how high they set it stock at XFX? The specs do not say does not say. I'll have to upgrade the monitoring software and measure during a run to see what it registers.
I'm wondering if they did a shitty mounting/pasting job at the XFX factory, and if I should take off the block, and give it some Kryonaut goodness. (Really not looking forward to that...) Appreciate thoughts.
3.) What do you guys recommend I do next? I had a pretty good idea which steps to take with a reference card (set 2600mhz, find minimum stable voltage max out power limit), but now that I've already hit 22k graphics score, maybe I should shoot for more? I'd appreciate any suggestions. I don't have enough experience with AMD GPU overclocking to really know where to start.
4.) Is this Threadripper SMT problem mostly a 3DMark thing, or is it better to leave it off in games as well?
Overclocking Navi 2 is ineffective if there isn't also stable, sufficient power to back it up. Your card has a more capable VRM phase config than most regular 6900xt. Also, its watercooled on top of that. And its "stock" clock is an overclock that regular 6900XT "hope" to get. With that power section, its going to get every bit of benefit from those extra clocks.
