Topic: How Asus authorized service can tell that bios has been modified on RX580? - page 2. (Read 637 times)

Those people are devils, due to the management and pressure, they are probably assuming all the gpus they receive were misused for mining. If they check a capacitor and determine that capacitor died because overclocking, they can just refuse warranty. They have all the power. Only way is to sue them if you think you are right that they should honor it.

you have flashed the device with official firmware, without boost on mining, then they can not refuse warranty service

if the device is stitched, the warranty may be denied. I had that with a map RX580 same story was, just said that menano software.

Sapphire amd or evga nvidia, avoid all others like plague. Leave fans maximum 85% and if they stop, replacing them is okay, sapphire fans are $8 each, evga fans are around $10. If I had a 3 years warranty and knew they would not honor if I modified bios, I would not take the risk, thing is, 3 years have not yet passed, mining started heavily only in 2017, so if you bought a gpu before july 2017 which at that time mining was not included as a misuse yet, then, all warrants should have been honored regardless of anything but as greedy as they are some manufactures will not honor it at all, so avoid them in the future.

I have managed some good amount of mining rigs with many of them being Rx580.I have noticed only one thing and that is Rx580 Sapphire Nitro+ are the only cards worth buying for mining,in fact I have yet to see one failing because no one has failed with modified Bios running almost 31 mhs and at 80% fan in a relatively warm environment.
Sorry for your loss.

I'm not sure whether the authorized service can determine the date of the latest BIOS flashing, but they can accurately determine that BIOS was changed by comparing checksums with the original one. If you get into a situation when the card was flashed with a modified BIOS, then it broke and you cannot flash it back with factory firmware, then you can be absolutely sure that the service center will detect it

This is why flashing cards is stupid.

So the card had a three year warranty.

You lost it .

I have said over and over and over don’t flash bios.

Don’t over clock

Don’t run fans at 100%.


I have been through about 450 GPUs.

Only six or seven  RMAS. Everyone was honored.

So my cards last three or more years.

Now of course you lose on power and has by not using best bios.

But if your power deal is good it does not matter.

Sorry for your loss due to,flashing.

If they have the card they will know if it was modified and to know if it was or not is very simple, just need a device that reads bios files and see if there was a modification in which for them compromised the ability of the gpu to work properly for the warranty they stated it to be. For example, they give warranty of 3 years for a bios settings, you go there and modify the bios in order to make the product to give 20% more performance, they can justify that 20% performance increase as why the card stopped worked, inside the pcb there are various components that were placed there to work only at stock, 20% more or overclocking make those components to work 20% harder, 20% more heat and that makes it at least 100% or 200% more prone to fail which in turn the 3 years warranty is outside the scope, reason why they give mining cards 3 months warranty.

The only way to circumvent this is to have a device that reads bios files too and if the card dies, you can take out the bios, change it to how it was, put it back and return it and hope for the best. I dont think there is a counter on the bios file logging how many times or if the bios file was modified, what they do there is compare original bios of that  model to the bios you sent them, if it matches then no modification was done.

The question is if gpu bios can be taken out, many motherboard bios can of many vendors, not sure about gpu bios and also depends of the manufacture and how they did it.

There are simple methods and complicated methods to determine if the BIOS has been modified. Many newer cards store the date of the flash file on the flash, so unless you can set your system time to the date of the original flash properly they can see it was modified. They did not check this in the past but now I know of at least 3 companies doing this. There are other methods as well, I'm too lazy to exlpain.

I live close to the RMA service centers and have a couple friends who work for 2 of the video card companies. Unfortunately they're within their rights to refuse warranty since the card was used outside of its stated parameters (unless its a mining card).

I had 10 asus RX580 cards. And of course all the bioses where modified and flashed for known reason.

Cards where fine, not the best, not worst, just fans started to fail soon. So I RMAed them all one by one. At the beginning I received new cards in place but later I made mistake, flashed wrong bios and warranty was voided. So I know why.  Recently I sent again 2 cards to same service center and this time i flashed exactly same BIOS file I had from one of the cards saved before. And I had warranty voided for both cards again.

So - do they really have a proof that bios was modified or are they playing me? Are they storing SN in bios or is there some kind of checksum that changes if BIOS has been rewritten? There is chance that I have been mistaken and I saved BIOS from card that I have been modified before OR... All cards came in 2 batches, maybe BIOS files where a little different for each batch.

But, to avoid that I have been just trolled and they can not actually proof bios reflash case - what are my chances? I have actually asked to service center to show me some kind of log file of some kind of software which they might use in case to check bios reflash event. Waiting for answer.
