Hi i bought a used Saphire pulse Rx 580 4g
sku:11265-09-20G
with the Samsung vram version
my problem is it have a modified vbios
with 1366mhz core clock
2000mhz vram clock
the problem that it doesn't work with secure boot on
and my motheboard
gigabyte b450m ds3h rev 1.1
the bios is set to make secure boot on
so resting the cmos doesn't work so i have to get an other apu or gpu so i can turn it off so the card can run
on my case i borrowed an apu from my friend cause my cpu is ryzen 5 3500
no g
and also the vbios show that i have the core clock on 1366
but it max at 1250 on furmark
i asked sapphire for the vbios but i gave them the wrong part number and iam waiting for a response just asking if any one have this problem with this card or its my vbios problem
and i tried to down grade my mb bios before secure boot with default enabled but my bios have this capsule bios feature i cant down grade my bios only upgrade and i gave the apu back to my friend and i need to make sure that when i change the vbios it will work with secure boot
so my pc wont be stuck again
and also i have an other question
i have power cut out alot lately so iam asking if the power cut during vbios flashing will the card survive and it doesn't have dual vbios.
and also here is my current vbios
