VBE7 custom bios always crash r9 270x

[sebaskitty]

hello.

i've been messing about with vbe7 with my r9 to see if i can improve the performance of my card.
but all the tests have lead to the system black screening after the windows login prompt and then the system reboots.
it stil displays the bios ect.
i can flash the original bios back with ease and it works fine again.

all the changes i've made so far in VBE7 was increase the tdp a little bit and the max overclock numbers and increased the voltage in the highest power state of performance with 50 mv.



whenever i load the stockbios in VBE7 i get the following error

any tips? my card is a gV-R927XOC-4GD

my motherboard is infact legacy only (it has partial EFI stuff but it's a server motherboard)

with stock bios the max oc i can pull is 100 on core and memory before it glitches out. and most likely hard lock the system (in my experiuence with nivida cards the driver would just crash?)

thank you in advance ^^

Uefi gets broken when modified, try adjusting without touching voltage.

Too bad @MrGenius is gone

Sometimes voltage controllers are locked out

I have a few links

I hope these help, i heard in 1 thread you want to use a hex editor to mod code, save it, then open it in vbe to fix checksum...

Extreme hw mod lol

A lil easier
