Flashed RX5700

[Mjoy4567]

Who here has flashed the RX5700 to the XT bios and what performance gains are you seeing?

I am currently awaiting arrival of my red devil RX5700 and am considering wether to reflash or to just push an overclock. Truthfully speaking I will still also try OC a flashed bios but potentially not to the same extent. 
Just a 1080p gamer so will get good standard performance but also looking to get reasonable benchmarks.

 

Thanks in advance

Im my honest opinion, i do not like flashing bios's and such. Partial risk if you dont know what you are doing, and generally i dont reccomend it.

 

Make sure your card is on the list for properly getting it to work.

Relatively lower risk option would be to try a power play table registry mod. You should be able to crank that Red Devil up to 1900MHz on core with either option.

 

At the very least, you have a dual BIOS switch, so if you lose power during the flash or screw it up otherwise, you have a safety net to fall back on.

I am quite confident in what I am doing and being a dual bios card very assured I could recover from any potential bricked situation. I have already done research into the card and have already got the bios file which I will be using. 
I am just after some real world results before receiving the card and not sure which route to go. 

In all honesty if I don’t get a few unbiased responses I will just see where I get with a modest overclock in afterburner before doing the flash and do the research myself. I was just trying to save myself some time by asking here.

 

Thank you for your reply.

I was going to try avoid the power play table as to me seems like more effort then worth providing I can get a more permanent boost by using other methods. 
I am also not experienced with changing any registry values so would be my least confident method. 
 

Thank you for your reply and thanks for the extra line of thought as to which way I could go with it.

Bump, anyone have any experiences with a flashed RX5700 to the XT variant and want to share the pros and cons? 
 

Thanks

For those looking to do this mod. I found it quite easy albeit with a bit of research and educating myself. Attached is the card I flashed and before and after results. Results are “out of box” and no extra settings other than fan curve had been applied. 
 

Thanks

That’s a nice performance gain. Have you done any other benchmarks before and after? What about temps before and after?

 

I have the same cpu as you and have a rx5700 coming in the mail today. I’m comfortable with flashing bios, have done it on numerous other parts in the past. Looking into doing it now

Very nice! That's about in line with the 10-15% increase I've seen from others. Have you tinkered around in Wattman after the flash? If so, what core clocks and voltages have you been able to achieve?

[Mjoy4567]

I was initially having a lot of consistent black screen crashes on my system assuming due to compatibility issues, but rectified that by changing the pcie slot from 4.0 to 3.0 and it was instantly stable. I then did the flash and have recently tried playing around with clock speeds and voltage.

After the flash I get the feeling it is close to the ceiling as far as clocking goes and was only able to squeeze 2015mhz out of it but then had to drop back down to 2000mhz for stability. With the clock at 2000mhz I have now been able to drop voltage back down into the ~1100mv region when at 10mins on heaven it was sitting low-mid 60’s on temp even with my very aggressive fan curve. 
Custom fan curve was also another issue I am running into. No matter where I set the curve it must be locked into the card to overwrite it with the 0db fan and they won’t start spinning until 60c where my custom curves kick into full swing. Anything immediately after the custom curves are accepted but once the temps drop back down and fans stop spinning takes it to get back to 60c for them to even start again. I have tried this in wattman and afterburner both with similar results. My preference is to have the fans spinning on low speed even on idle.

Over 20mins with heaven on loop and these are my wattman settings.
