Hi!
when flashed to the 12Gbps "Pro-Tuned", and also GPU Boost Clock turned down from 1780 to around 1600 Mhz works fine
Did you have to underclock your GPU manually to get it working? Ugh that sucks man, you should probably RMA your card.
they have been quite reckless while doing so
I definitely agree with that, they made a huge mess around their GPUs. A simple price cut would work better for them.
even if we were able to modify VRAM voltages, there's still a big issue that remains to be solved: unofficial Bios flash software (that allows to flash modded BIOS) works only with RX 5700 and 5700 XT cards. No RX 5600 compability yet. So even once we modify that, this BIOS would be totally useless.
I contacted XFX and AMD as I promised. Here is what I know so far:
XFX can not and
will not release any special BIOS for an end-user to manage issues like I described above. They sent me the very same BIOS that NumbComic sent here - obviously it didn't solve my issue. They also sent me another BIOS, designed for mining - however it wasn't something I would want, as TDP is lowered there to just 125W, GPU clocks remains at 1200MHz I believe, memory is capped at 1500MHz. This isn't something I wanted. They also advised me to adjust VRAM voltage via Wattman software (
which is not possible XD because Wattman allows you to adjust only GPU voltages). Ultimately when I told them their solutions aren't working for me - a technician advised me to RMA my card... which probably wouldn't work, as my card officially doesn't support 14Gbps memory
After that I decided to contact "the king" - AMD Tech support.
I described everything in a great detail, I gave them possible solutions to this issue (that would be really helpful to a larger number of users, not just me!). Unfortunately their answer was quite underwhelming. They said, that my card was working fine with 12Gbps BIOS, and wasn't working with 6Gbps BIOS (??? 6Gbps ??? never heard of this!). Then some yada yada yada talk, and finally - they said I should contact XFX to solve this issue from the BIOS side! Really useful tip, thanks AMD.
So as you can see, nothing can be done about it. I guess something could change if some big tech-youtubers raised this subject, but unfortunately (or fortunately? huh) the issues apply to few % of all RX 5600 XTs.
Our only hope is to look forward to getting some BIOS modding tools allowing to change VRAM voltage, which tbh I'm not expecting to come soon / at all.
Personally I won't do anything for now with my card, I won't RMA it, as the performance is ok anyway - and it doesn't support 14Gbps memory officially.
Greetings!
Mike
P.S. My AMD tech ticket is opened till 18.07, so if you have any clever idea on how to get something more from them than just the answer I got - go ahead and let me know!
