One RX 570 Draws More Power Than Others

[AVP]

I have 3 MSI RX 570s 4GB cards, with modded BIOS using 1500 straps, all were mining happily at about .0885 vcore. All was fine for a long time. All 3 cards were drawing ~120 watts each.

But recently one of the cards started drawing a lot more power, it started jumping between 150 - 170 watts, card seems stable but as result runs too hot with fans at 100%. No changes were made at all.

Any advice on what the cause of this could be?

Thanks.

If the power is "jumping" it looks like increased load from another process starting up.

The important thing is how is the card performing. If you're using 30% more power and getting 30% better
performance that's a good thing.

The card could be dirty, not sure how that would affect power but certainly temperature.

Otherwise it mght be starting to fail.

It could be 2 or 3 years old and ran hard for all that time.  The caps in it may be failing.

I had something similar happen years back with a R9 280X. Basically all of a sudden the power consumption went up, I did some investigating and some card started to draw more and more power. Then shortly after the rig just shut down. I assumed it was a crash. I started it back up and .... BOOOM! Biggest black cloud of smoke and my room stunk for hours of burn electrical parts.

I took the GPU apart and something must of shorted out because there was a huge burn mark in one area. Might of been a capacitor or MOSFET. If it runs for days I wouldn't worry about it, but if it just started happening then keep an eye on that GPU.

I have similar problem. My rigs working at my balcony. It rained 2 weeks ago, raindrop came over gpu.  My rx 570 now giving half of its hashrate (13,70 mh/s) and draws 250w (before: 80-88 w) What should i do? I wonder if oven method works at this situation

Probably not. The oven method is only to reflow the solder joints on the GPU chip (called the ASIC chip) of the PCB. Generally due to the heavy weight of the heatsink or when someone does a thermal re-paste job and pulls too hard on the heatsink assembly to seperate, they can cause microcracks in the solder joins.

You can verify this easily, if the problem goes away when GPU is hot, but you get problems when GPU is cold then its solder joints because they are more spaced apart when cold. Hence the oven method would work. However your issue is most likely some corroded parts due to the rain, open up the GPU and see what is damaged and try to replace. If its a capacitor or resistor you might be able to fix.

Same her on one of my MSI 570s, it runs 90 degrees and higher power and no matter what I do it always runs at 90 degrees.  I've re applied thermal paste and the fans run at 100%.  I'm waiting for it to break to throw it away but its been a year an still running, lol.  I wounder if the temp reading is wrong.

Double check that the GPU is honoring the voltages you set
