I just flashed this to my card, flashed without an issue, but hwinfo still shows 365w as max power. Is that just hwinfo showing incorrect info or is my issue something else?

You need to move the power slider to the max in afterburner or PX1 other wise it will still be the same.
With this bios it goes from 100-110%, Stock bios goes to 100-104%

I think something else was the issue, after another restart and a benchmark in hitman 3 it went past 380w.

But this thing (mine at least) cant beat a 3080 FE, when I compare it to all the benchmarks I find with similar specs (1000w Seasonic Plat, 9900K, Z390 Board, 32 GIGS Ram)

It's not just evga cards, I just offloaded a Inno3D RTX 3090, stock it would hit 85c, downclock to 1650Mhz, well under the advertise speeds.
Benchmark results were shocking, no OC headroom, just to use the card you had to undervolt.
I was told it's "normal" by the retailer as they tested another one they had which has the same results.

EVGA do have official bios updates, it's no big thing to flash a better bios, they have made it easy to do, heck even the Inno3D software had a built in BIOS back and flash option.
 
These cards run hot, the Hybrid doesn't cool the rear Vram, which you'll find are running hot, I plan to mount a 92mm Noctua fan to the back of my 3090 XC3 Hybrid when it turns up, it does make a difference, dropped the Inno's vram temp by nearly 10c, increased the benchmark score a little, just the card fan's had to be run at 100%.

When my XC3 and Hybrid kit show up, which should be tomorrow or Monday, ordered the card and kit from different stores, I'll run a few tests for you comparing it to the Inno3D I previously had.
I'll do that with stock and this custom bios.
 
I'm in Australia, it's in the middle of summer on the Gold Coast, so temps are hitting 30-38c some days.

This is what I was getting with the Inno3D on Time Spy Extreme and Port Royale.
You'll see the clock average is 1756 MHz, yeah the card was that bad.
Temps say 68c, but that's with 100% fan undervolted.

Oh man I'm so glad I found this post.
I was just about to post a big rant and rave about the piss poor performance I'm seeing with my new EVGA XC3 Ultra 3090 that I got today...
These are my scores
17129 on Time Spy
12326 on Port Royal. From what I've seen these cards should be doing 13k min.
 

Have you seen the clocks people are using to get over 13k, I saw someone get over 14k, with a clock speed of 2.2Ghz.
Someone with a msi rtx 3090 ventus oc running the Gigabyte 390w BIOS got 13707 with a +160 core, +1000 vram.

It's not a simple as going "card should be doing 13k min" that's not true, there's determining factors, stock 2x8pin card with 350w power limits will not do it at stock, like the XC3, flashing a better BIOS like what bmgjet posted may get you over 13k with some fine tuning.
 
If you're only worried about Port Royal scores, you honestly should of bought a 3x8pin power monster with custom water cooling flashing the 1000w XOC BIOS, the 2x8pin cards are good for the average joe wanting to use the card as intended with some light overclocking.
You're never going to keep a 3x8pin card cool on their stock air coolers either, it's just what these cards are.

I don't know is EVGA Precision X1 has the same feature, but with MSI Afterburner you can set a voltage/frequency curve setting.
You can lock the card in to a hard clock frequency based on the voltage it pulls, it's what I used to undervolt the Inno3D fryer.
I manage to lock it into 1785Mhz, which it stayed at unless you ran Quake II RTX, which kicks the crap out of these RTX cards resulting in 1500Mhz downclocks. (Try it out for yourselves you'll see).
 

 
A 750w PSU won't even run CP2077 at 450w on a 3090.  Guess how I know.  Lol  Didn't hurt anything but my system just shut off.  

Ok so I haven't put the Hybrid kit on yet, no BIOS flash, but I'll post this to point something out.

I compared the EVGA to the Inno3D, I overclocked the XC3 to the Inno3D clocks, set the same fan profile and the EVGA walked all over it.
I couldn't overclock the Inno3D at all due to temps, the XC3 ran at a constant 1850Mhz, where the Inno could even with the same fan speeds.

Don't knock these XC3, they are as fast as, if not faster than any other 2x8pin cards, stick the Hybrid kit on it, you have a winner for a quiet top tier gaming card.
If you're shooting for 3DMark leaderboards, you are buying Kingpins or HOF at the end of the day.
All the other Air cooled cards whether 2x8 or 3x8pin all suffer from downclocking and heat unless water cooling.

Outside of constantly hitting power limits i dont feel disappointed in the card like i did with my 2080ti.
It has potential to oc well, in some games ive seen it hit 2080hmz stock, but any demanding game itll hit limits and go down to 1890-1925mhz.
In game i hardly notice that, and it is a huge jump over my 2080ti, which that itself wasnt much of a bump over my 2070s. Temps ive never seen above 63*F, although this is my first aircooled card i was expecting it to be much higher.
Debating the KFA2 bios, but wondering if its worth the risk or if the extra 30ish watts will even make a difference.

I'm kinda apprehensive to use the Flash because I only have min required PSU, which is a Corsair 750. And the card cost me a lot in my country so if it goes wrong I'm hugely out of pocket.
Rest of the system is
Intel i9 9900K @ 5ghz
32 Gigs DDR 3200 CL16.


I am glad though that I'm not the only one it's happened to, but I have to admit I'm pretty pissed off, I expected big things from EVGA and this is the first time I've brought one of their cards.
I might return the card as I only just got it today and get another brand with 3x8 pins instead. Might be safer than flashing the card and having it die on me and lose over 3 grand...

 
I flashed the KFA2 bios onto my XC3 Ultra and am happy with it. When I ran Port Royal my score was 13,412.

I'm also running a Corsair SFX 750 watt power supply and have been just fine. My 9900K is at 4.8ghz. The most I've ever seen while gaming is about 600-ish watts total system (per my Kil-A-Watt). If you want to flash just follow the guides, it really isn't that hard and you should get some more performance out of the card.

I run CP2077 just fine, with a 3090 (390w) and 9900K.

So did I. Worked fine at 390w. Not so much at 450w.

Your Port Royal score should be another 200 points higher.
Make sure you have completely closed Percission X1 if your using that.

schoolofmonkey
Last one.
+150 core
+200 memory
111% voltage slider (104% on the stock bios).

The 390w BIOS does have more overclocking headroom, but I wanted to test the overclock with just the extra power draw.

Do you have the 3DMark score links so that I can compare the two BIOS? I’m more interested in the changes for the graphics score alone and not combined score. Also interested to see clock speed differences for each run.

Thanks! Honestly thought it would make a bigger difference.

I did have Rivatuner running so the scores are a little lower, but nothing where you'd go wow.

Honestly I went back to the Hybrid BIOS (seeing I installed a Hybrid kit), I noticed no difference in actual gaming when I set a +100Mhz core +200Mhz on memory.
Boost clocks depending on the game can hit 2080Mhz, but never go under 1900Mhz (Quake II RTX different story, but that's normal), which was pretty much the same as the KFA2 bios.
As the card is for gaming, it's not worth running the KFA2 full time, benching yes, but day to day no.

Yeah I was comparing your average clocks in the benchmarks and it seems that the 390W BIOS only increases your clock speed by a solid single 15Mhz increment overall (~20Mhz average clock increase) compared to the stock 366W BIOS. Was hoping for a solid two step increase of 30Mhz but maybe that is asking too much of a 24W increase.
