Can you link something? You keep telling us that there’s a million ways to do it wrong but I need something to see what this right way is.
In terms of a tutorial, I liked this guy’s video. Don’t worry about the length of it, the tutorial part is only the first 3 1/2 minutes. It’s pretty straightforward.
I have a FTW3 Ultra 3080 and I just used the Fan Xpert4 that came on the Rog MB and the curves seem to be fine. I don’t get any loud fan noise with my CPU or GPU even when pushing it as hard as current games will go. I’m not in the New World beta so that may not mean much.
I don’t know whether it’s my particular 3080 model or my case, but it never gets hot. It’s very rare it even breaks 60 C. In contrast my CPU seems to run pretty hot, pretty regularly getting into the 80s under gaming load (though the recent MSFS patch has removed the worst offender, using time acceleration in the sim) and typically settling in the high 60s/low 70s.

Zen3 CPU cores are extremely small physically so they concentrate their heat in an extremely small area. This isn’t bad, it’s just different from intel.
My EVGA FTW3 3080 doesn’t get hot either, it has extremely high-end cooling, it just generates a ton of heat. Before I applied a voltage curve it actually made my 1000VA UPS beep for overload. That’s never happened before, and didn’t happen with my gigabyte 3080. The FTW3 uses a lot more power.

My curve on a 3080 (not 3080ti) is 950mV at 1900Mhz alongside a +500Mhz RAM overclock. Anyway this dropped me from over 400w to 350w peak without really impacting performance at all. Maybe lost 50Mhz on the core.
I could get a lot more aggressive and tune individual points on the curve but it doesn’t seem worth the effort. I did try 900mV at 1900Mhz and that crashed, didn’t bother narrowing it down to 925mV etc.
AMD released a new card! That is pretty much a 5700XT from 2 years ago + ray tracing.

Many reviews say it’s slower, at 1440p and higher. That’s why it’s being marketed as a 1080p card. It’s physically pci-e x16 but electrically only x8.
Remember the 5700XT was basically a RTX2080 in rasterization and that was more than capable of playing 1440p games. Hell, that’s basically what the PS5 and XSX are running.
And it will still sell for $500 over MSRP, and you can’t find any in stock.
There will be plenty of stock on Ebay and Craigslist. :)
How warm is the room you have the computer in?

What do you mean + Ray tracing? Support in drivers? It doesn’t have the special tensor chips that nvidia has for that afaik
Tensor chips are for DLSS, not ray tracing.

Ah, how is the +ray tracing handled on AMD series 6000 GPUs? (I’m out of the loop)
Every RDNA2 compute unit has a dedicated ray accelerator.

Thanks. And even with that it’s an average of 30% slower than RTX 2000/3000?

In RT yes. This particular GPU is severely constrained on memory bandwidth in particular. That’s a much bigger concern than RT performance IMO.

Prior to the 3080, the room was typically 73 degrees, sometimes 74. The 3080 seems to raise it up to about 76. (all these temps Fahrenheit, since we’re both US-based).
I tried limiting the framerate; the monitor I have it connected to is 165 Hz, but limiting framerate to 165 didn’t seem to help. I’m going to limit it to 60 and see if that makes a difference, then start messing with voltage curves this weekend.
If it helps, the card is an EVGA 3080 FTW3 Ultra, which is, I think, just the regular 3080 FTW3 with some blingy LEDs.
