Just purchased a 2080 Ti Black. Performance was low in games (COD) and temps were up to 83, I put a water block on it and now temps are 62c on load; however, performance is still crap. I ran a userbench and it showed my GPU performing almost as bad as a gaming laptop. In contrast, my friends 1080ti is getting much better frames at the same settings. I'm running a 8700k with 32GB RAM. 
GPU-Z shows power being drawn jump to ~200w and then max out around 150-160w under load. My last guess was that it was my old crappy PSU (replacement for which should arrive any hour now). 
 
I also tried flashing to an updated bios. Current X1 shows max power to 112% (I have the A chip model that is specified in this post ), but after running the updated exe I just get "ERROR: NV_UCODE_CMD_COMMAND_PREP failed". No luck successfully flashing any other bios with my limited knowledge on how to do so and constantly getting errors showing incompatible firmware or out-of-date nvflash 5.590 (using forums and CMD prompt). 
 
Will try to hook up the new PSU if it comes today but I'm really running out of options.. :( 

Isn’t the GPU rated for higher than 250W? Why is it going up to 200W and then settling at 170W? Hope you get better results after changing the PSU.

You need to type nvflash64 not nvflash.

In that case I would suggest trying older versions of nvflash until you find one that works for you.

So far, I've tried the one you suggested in the link above with the commands version 5.527.0 modified. Same issue. Scrolling up above "ERROR: NV_UCODE_CMD_COMMAND_PREP failed" shows "Firmware image requires a newer version of NVFLASH."
 
I found version on guru3D 5.513.0.1:
ERROR: Error reading PCI Configuration Space Register (0x00000032)
Detailed :The request is not supported.
 
I also tried a nvflash64_patched_5.590.0 using the same 2080TI-380w.rom. --protectoff works and during flash it shows the following at the end:

Let's hope so.. Amazon guy is taking his sweet time with the delivery tonight...

Don’t have expectations for 100% delivery rate based on ETA. Not sure how long you waited for your PSU. I placed an order for a PSU yesterday on Amazon with estimated delivery in May and today I got “upgraded” to end of the month because yeah, it’s non essential.

Lol As I read your post, guess what just got delivered. Wish me luck.

O_O looks like you got one of those new cards that has a different xusb firmware loaded to it. Which means you have to flash back to an older xusb firmware using a usb programmer before you can load the older gigabyte 380w vbios as it uses an older xusb firmware version, or you have to find another vbios that matches your current vbios xusb fw, and which also has a higher power limit.
 
Note: A vbios that uses/matches your current vbios xusb fw should flash without a problem.

 
Is there any info on how to do this? I'm brand new in the world of GPU oc and vbios. 
 
Just testing to see if the psu made any difference.

Simply flash the gigabyte 380w vbios doing that. 

Holy crap.. "simply" lol. Thanks I appreciate the help. I'll look into getting all this stuff. It's too bad the 2080 Ti isnt performing as well as I thought it would.

Looks like I might be in luck as Amazon in Canada has it . 
 
Will put the order in and report next week to see how it goes! Thanks everyone.

Literally all you have to do to patch is click the .rom file, then choose navflash/navflash64 to open it and boom install starts after you type 'y'.

Bigger fish to fry then.  That's all you need to do to update a vbios.
