Rx 5700 VBIOS flash

[Mero283]

I want to get the RTX 3060 but as we all know it's out of stock everywhere. The RX 5700 XT has about the same performance and I know you can bios flash the 5700 to get XT performance. However, I'm intimidated by the idea of bios flashing and the idea that if I brick it there's no going back. I don't think my card (ASrock Challenger 5700) has a dual bios switch though, so is there any way to get it back if I brick it?

My understanding is More accurately some models used to be able to do that with early versions of BIOS.  The problem is early bios versions are often bad ideas with AMD cards. I’m unfamiliar with the specifics though.  I would be very surprised if this is still possible with late generation stuff. 
 

as far as bricking goes the definition of the term implies no way to get it back.  Hence the phrase “brick”. A recoverable error wouldn’t be bricking.

Ok, thank you. I'm not really into bios flashing and I heard you can put it another GPU and flash your broken one so I thought I can put in my HD 7990 and flash the 5700 back.

The 5700 is broken? A bad bios flash wouldn’t Brick a 5700 because you could reflash it. I suppose if you had only one card it would be considered a bricked machine if you had a cpu that wouldn’t work without a discrete gpu. I don’t know what model you have.  It’s not impossible if it’s an early 5700 and you got ahold of a bios that worked on it you could make it go faster.  It would require very specific stuff though. The most current 5700xt bios probably isn’t it.  I don’t know specifics though.

I think he means IF the 5700 gets bricked during the BIOS flash.

Yeah, as FakeKGB said I meant if it gets broken by a bios flash and I'm way too scared to do it rn xd. The card I have is the ASrock Challenger but flashing it to an XT model might cause other issues aside from breaking or bricking it like the thermal output being too high for the cooler to handle. It gets very warm as it is. When I run heaven it goes to about 80-85 degrees celsius-yikes. Though my case isn't super well ventilated and I have just about the worst cooler design one. Also my room is warm so that might be another factor. I found the exact same card as mine just the xt variant on techpowerup. Also another question, if I flash it to the XT variant do I also need to install the XT drivers? Thank you for your help though.

Finding someone who has actually done this would likely be helpful. There was a point where such things were being done.  My memory was it was a lot like every other similar thing where an exploit was used to make a piece of electronics more useful.  It is eventually blocked by the manufacturer often sooner rather than later.  I owned a 5700xt for only a brief time though (just long enough to show that it would not drive my ancient weird WUXGA monitor) and therefore didn’t pay a lot of attention.  There are people that did.  I lack specifics.  My memory is you are referencing a fairly brief point well over a year ago though.

I think just using Igor's MorePowerTool pretty much gives the same results as a BIOs flash if you change the right settings. But it might be too complicated for you to use if you don't know what you're doing.

hi, thanks for all your great work, I have a aorus rx 5700 xt, this board doesn't get recognized on startup anymore, since my aorus ultra x570 downgraded the bios from f33h to f30. it was getting junction temps of 113 C, so I reinstalled f33h and thought it all good again. but then I restarted my pc a day later and since then it goes to start up loop, the lights move and checks hdd, ram, etc. and stays on VGA, the loops back...I checked psu with other board and GPU, changed RAM and all works fine. so I tried with an Nvidia card, also all good. So my Idea was let me check and try to reinstall the bios..so I installed the nvidia card in slot 1 and the aorus rx 5700 xt in slot 2, and it started and I could see my rx 5700 xt in the device manager, so I tried to reinstall the bios with atiflash, but there it says its the same bios, funny thing is in the size of the old bios it shows the size of x00000 and the new bios that is the same one x8000. so here is my question; I can't install the bios because of secure boot and my mobo is UEFI, so how can I install it? can I delete or empty the bios chip on the rx 5700, and where is it and how do I do it? since so many people have these faulty GPU`S its may be a good video for you to make. thanks for your help.

Why did you put an rx570 in a machine that had a 5700xt in it?  NVM there are probably reasons.  I can see AMD not expecting someone to do that though.  It sounds like v30 changed something and removing it and installing v33 did not change it back.  If you didn’t use DDU to remove v30 that could explain it.  Video driver uninstallers don’t always work correctly.  It’s possible you may have to reinstall your system stuff.
