I have a problem. I own two Gigabyte Vega 64 Gaming OC and flashed them with the wrong Vega 56 BIOS I think. Now, they are both unrecognized in HiveOS - did I screw the cards now or can I revive them anyhow? 
Edit: Problem was solved.
there’s a guide above in the first post on how to recover when bricked.
just have to do a little bit of work and a bios switch move around.
The Gigabyte Vega 64 Gaming OC is just a really worse card. Flashed it to the Gigabyte Vega 56 Gaming OC bios and it doesn’t run stable with these settings, keeps messaging DEAD GPU and restarting:
Clock: 1000
VDD: 830
Memory: 1000
amdmemtweak --CL 20 --RC 37 --RP 11 --WR 14 --CWL 8 --FAW 12 --RAS 20 --REF 65535 --RFC 248 --RRDL 6 --RRDS 3 --WTRL 9 --WTRS 4 --RCDRD 12 --RCDWR 12
I left my card now @ 1000/800/960, 45,5 Mh/s @ 160 W.
This card fu*** me really up. Mediocre hashrate and ultra high consumption…I will soon kick the two Gigabytes out of the rig and replace them with efficient cards…I am really pis***

i get about 46.7 Mh/s @ 145 watt
Clock: 915
VDD: 765
Memory: 845
amdmemtweak --CL 18 --RC 35 --RP 11 --WR 14 --CWL 8 --FAW 12 --RAS 26 --REF 65535 --RFC 239 --RRDL 6 --RRDS 3 --WTRL 9 --WTRS 4 --RCDRD 11 --RCDWR 12
Ok tried your settings now: Working since 14 minutes stable right now
46,4 Mh/s @ 145-149 W
holy, finally after struggling for about two whole days… 
ok
you can test if you can go higher on the clock maybe 920
i can not go higher then 915 maybe 916 or 917
I had a crash now and went back to 910, lets see. I don’t know, if its the core clock or the memory, but I don’t think the memory clock with 840 is the problem here.
ok
yeah that’s how vegas are, but once you found the stable oc you’re set for good.
I had 1 week before i got rid of dead gpus. somehow you have to configure the card 1 by 1 until you found a good mix and match.
Mh, after installing the RX 570 8G, my Gigabyte Vega 64 (flashed to Vega 56) are restarting with GPU Deads.
Should I just leave the 570 out of the system?
Hi, I’m new to flashing, so i just need advice for chosing bios.
I have:
1x Sapphire RX Vega 64 8GB
113-D0500110-O01
and
5x Asus RX Vega 64 8GB
115-D050PIL-100
Found bios for sapphire:
And for strix:
Is this bioses safe to flash on this cards?
Thank you in advance
Is there anyway to identify the following parameters in Hive OS? I do not have access to a PC to install the card into to get Device id and Subsystem ID. I would like to flash my 64s to 56. This is what I find in Hive OS
these are fine and working well. i tested them as i have these kind of gpus. though asus strix model are like to consume more volts compared to other models.
might be your PSU is having trouble to power them all with the rx 570 included. i’d say its the power. i always use the model of not using more than 80% of the PSU’s load capacity.
its the number at the bottom of your GPU.
Example 03:00.0 and 07:00.0
Thanks for the response. Any advise on the correct 56 bios to use for these 2? New to this mining and flashing and wouldnt want to brick it just yet
Thank you. Cards are flashed to 56.
Is core 1075 / volt 870 / 1050 and straps from 1st post ok for them?
I am using the HP server psu with 1200W. I have also installed a power monitor on the wall.
It says 819 W in total for the rig.
My biggest concern actually is, that the MSI Air Boost Vegas are going to 80-84 °C. The Gigabytes sitting around 73 °C.
I have just a 30 cm ventilator sitting in fron of the rig and blowing in the direction of the window. But I have to do something here…
