Yes you could work with these clock speeds and think everything is OK but unfortunately it is not (if you ever seen Buildzoid videos about this matter). I guess almost every 3080 FTW3 Ultra has the same behaviour about it, let me say identical. Please keep your Core as +130 and lower your vRAM 400, then increase it as 500-600-.... until you notice a drop and here is your limit. Don't try to push it more over because it will be useless (such a shame). Even if you totaly solve TDP issue you will have this limit. Your system won't crash and you will see your vRAM is higher but it isn't (your feed for vRAM) stable anymore so your score will less then lower vRAM values.

That's the thing though, I started at +200, then +500, then +800 on the vRAM, score went up every time.  That's why I'm so confused as to why the score went down from running the Core & vRAM OC at the same time... I'll fiddle with it more tonight perhaps.
 
I did get a new personal best on pretty much all the benchmarks with some spicy meatballs settings though.  CPU @ 5GHz, RAM @ 4GHz CL17 (which I tested as being "stable" but we all know how RAM OCing works, it's stable until it isn't sometimes) & the 3080 @ +130/+800.  Every benchmark scored higher than my previous bests:

The most important part of the GPU OC is core as you know. So increase the core as much as you can until you get a drop (or even crash) then if you are sure about you have found the stable core clock, switch to the mem without changing your core. Because you can’t feed the core and mem in the same time. One of them will be hungrier and it will cause a drop or crash if you try to increase them simultaneously. I’m sure that you already know these steps, it is just a kind reminder.

Seems like I am having the same issue, the higher the clocks the performance drops (card does not crash), in some benches and games but not others.

I settled around +120 core which brings me to 2085-2100 boost and +400 on the ram, but any gain with ram clock increase is negligible I noticed.

Can we have something like this for the XC3? I am hitting power limit all the time even with low clocks... I was thinking about watercooling it, but with this power limits, I don't think there is gonna be a great improvement...
 
BTW GPU-Z reports maximum of 340W Board Power draw, even when I have 107% Power limit selected, is that a bug or something? It should be hitting 366, right?
 
I settled it down to 1920Mhz @ 918mV on my XC3 Ultra for daily use, it runs cooler, just in case anyone is running one of these cards

No, because of the 2x8-pin power already being maxed out.

I’m waiting for XOC 3090 FTW3! Good Job!!

saaaaaaaaaame. although im pretty certain I need some major cooling upgrades to facilitate using that bios.

When will it go out of beta?

Any update on XOC bios for 3090?

is this okay i'm hitting over 450 watt of usage while playing Metro Exodus in 4k/with ray tracing/ultra setting  temps is around 65-70 degree should i be worried? I did apply the OC BIOS to get 450, just a little surprise that I was drawing 450+ power. I'am OC 130+ /1000+
