I’m trying this now but every time I apply the 56 bios Ron flash is ok then on reboot hive freezes. And help would be great. My card is a sapphire nitro + vega 64.
Any advice for a sapphire nitro + vega 64 every time I glash a 56 bios flash is ok then reboot just hangs on hive boot screen . I tried the flash on both bios settings and it never boots after. Flashed back to standard bios and I get a terrible 22mh/s @ 160 watts. Please help I’m gutted this card was £600

hi, same device id but different subsystem id, is it safe to use?
can you post a screen shot of your sys id, use gpu-z
I had successfully flashed to vega56 bios by following your guide. Felt so good to see the hashrate stable at 55mh. Great thanks and appreciated.
yeah, mining efficiently feels great getting the max hash you can get 
happy mining.
Hi Akosi, I have a vega 64 of amd/ati. these are the specifications can you help me with the 56 bios?
Have you made sure your bios switch is towards the back? That was my problem with my sapphire

Hi, i can’t seem to find your bios device id. Can you post a picture with the brand of your vega card or who’s the manufacturer?
MSI? SAPPHIRE?
I assume this is the blower edition.

With your settings @akosi my Gigabyte keeps shutting down the whole rig.
So therefore it seems these settings doesn’t work for Gigabyte Vega 64 flashed to Vega 56 Gigabytes.
Sad 
Hey dude
Got some problem with my Gigabyte Vega 64.
Flashed it to Gigabyte 56 and does not run well. Can I flash it to a Vega 56 ref card (MSI) no riks of bricks?
I’m not real good with flashing only did my 64 with guidance from here, first time i bricked a bios and thankfully got it recovered
What BIOS did you end with? I can’t find anything over 150/165W and I have the same device id / subsystem. Please share.
Hey all, I am currently running three Vegas one of which is a 64 flashed down to a 56. Two of the three run in the 185-190 mhs on autolykos with no problem. One is a 56 that I can’t get over the low 170 range. It’s a XFX Radeon RX Vega 56 or it’s listed as the dual dissipation one in the list of bios. It constantly runs at a way lower clock that I set and I can’t figure out why and I’m wondering if it’s the bios of the card and if I can flash it to another bios to maybe get it to run better. I attached the amd info from the card for reference. Any suggestions are appreciated.
This memtweak dont work for me? U use vega 56 bios on vega 56 and how much get mhs?
Has anyone been able to find a vbios for the Sapphire Vega 64 card with ID 1002 687F
1002 0B36? The only Vega 56 vbios available are 150 or 165W. No 220W to be found unless I go to other subsystem ID’s.
EDIT: in case anyone is wondering for this card ID, I went a head and flashed a 165W vBIOS, specifically the one linked below.
