Problem with 200% TDP on RTX2080TI

[RailWay89]

Hello
I just bought a second hand MSI RTX2080TI gaming x trio.
when I first put it in I had some problem that it wouldn't want to clock up (Maybe the same problem as described farther down, but don't have data to support it).
After a few restarts and plugin in and out the power cord I got it to work and played some game and run some benchmark and it seamed fine.
After a restart it started not clocking up again and I couldn't get it to work again.
After reading around and installing GPU-Z I could se that the reason why it didn't want to clock up was because it think its drawing 200% power on one power connector.
What I tried so far is
1. Taking the card out and putting it in again
2. Reflashed the bios to a newer one of the same model

is there anything else i cant try before giving up on the card?
I have attached two photos from GPU-Z that maybe can help showing the problem

Help appreciated

It's defective, hope you can return it.

Considered that it's second hand and the card seems to boot up fine, it's possible that this card was subjected to a botched shunt mod that decreased sensor resistance instead of increasing it, causing the reported wattage to go sky high (and the GPU to heavily throttle as a result). If it does have the shunts re-soldered, then you could probably shunt mod it yourself to workaround its power limit. If it is of no interest to you, return the card.

Yeah, Stop thinking a bios flash is a miracle fix, just dont do it.

Buy brand new and you wont have most headaches, the second hand market is full of scammers. Do not buy from ali express or facebook market, stick with amazon, newegg, ebay as they have buyer protection

Hello
Thanks for the answers.
Will probably try too do the shunt mod because i cant return the card.

Ok well it breaks you will have to buy a new card. Shunt mod is not worth it anymore

Check first to see if there has been a mod done already.

Dishonest seller. Everytime someone makes a posts like this all I can think of it's either a mining card or modded in some way.

It's looking like you need to fix someone's botched shunt mod instead of doing your own

Pics would be helpful, of the resistors around the power connector area. I still think you should return the card, though. This is an advanced modification. If that is not at all possible... then you should read a lot on it before attempting the feat.

It's kind of the only way you can get extra power on RTX GPUs nowadays, without a BIOS editor being available :S

That's how it is for me, it's automatically a mining card now...

Hello everybody

I have now taken pictures of the card and what I understand there is a fuse that have been "removed",
It also seams an excessive amount of cooling paste have been used on the chip.

So im not sure which connector is which is the connector with the "removed" fuse the connector that is reading wrong?
Anybody have any suggestions what to try? try resolder the fuse?

Also thanks for all the help and answers

Ask Krisfix.de or Northridgefix on youtube

Yeah that's a botched shunt mod you are dealing with. One of the resistors has been completely jumped.

Fortunately, TPU has a review on your specific card and W1zz takes high-resolution pictures for the reviews:

As you can see, the middle power connector with 8 pins is missing one of the surface mounted components at position F4 which has been directly jumped with a blob of solder, and that is why your card is reporting this extreme power consumption.

This is a false reading, the card is not drawing that much energy but since the BIOS thinks it is, the performance will tank as the card will always believe it is overloaded to the brink and enable all power management safeties. Shunt mods are done to reduce the detected power draw, but since it was done incorrectly, it caused it to report a sky-high value.

Unfortunately, I do not know the exact resistance values and corresponding parts to safely point you out in the right direction, you will need to have your card serviced by a qualified technician. The good news is, this graphics card is not dead and should be fixable... if you figure out the correct resistor part to install there and can (or get someone to) solder it there for you.

You may be lucky if you ask people at the OCN forums or maybe on the r/overclocking subreddit.

Appears to be a 20 Ohm resistor, but I can't find one with a similar-sized package.

Based on what Igor's lab says, you might be able to steal the one from the 6-pin connector, as it is apparently redundant. Just make sure you do not use the 6-pin if you do that.
