New BIOSES by Buildzoid / Mr.Cleaner !

-> http://cxzoid.blogspot.fr/2016/04/possibly-last-batch-of-custom-fiji-bios.html

 

Today i was plaing with new BIOSes -> Unfortunatelly it won't work with my Nitro OC+ (this one "New BIOSES by Buildzoid / Mr.Cleaner !")

But i have compared my BIOS (Unlocked with tMOD and V HBM Mod) with Normal one and with NitrC_Zerod_voltage_offsets without tMOD.

My BIOS have scored ~500points more in 3D Mark (Perf. Mode)

Max at 1120/570 (My BIOS) was 17034 GPU score
Zerod no tMOD Unlocked = 16 548
Normal BIOS (Unlocked via atomtool_v11) = 16 552

Core set to 1.212v and all runs was at same Clocks & HBM
My Moded BIOS with tMOD and HBM Voltage is strongly recomended for Nitro OC GPU.

Download My BIOS

UPD.
Max at 1120/570 (My BIOS) now: 17070 GPU score on ReLiVe 16.12.2 Jan3

 

I Would like to mention that the memory timings mod works on my 6870. It gave a +4-5% performace gain using 900mhz timings. was able to a get 3380 graphics score in firestrike using 1040mhz/1194, 900mhz tmod with tesselation enabled.

 

+1

Tweak more -> If you can pick some Fury

 

My BIOS for Nitro Fury HBM (im on this one since summer)

:nerd:

IMO Best BIOS for Fury Nitro

Try Flash this baby into first slot if you have Intel UEFI Platform, Blue Slot if AMD UEFI :nerd:

 

You said it again.... Blue bios on the sapphire cards is the UEFI bios, it has the same clocks as the non-lit bios, the non-lit bios is for motherboards without UEFI support.

If you flash over the blue bios without backing it up, you will lose native secure UEFI support.

Edit for for info:
Quote from http://www.overclock.net/t/1592384/fiji-bios-editing-fury-fury-x-nano-radeon-pro-duo

If you edit or overwrite the blue bios (the switch on the board that lights up blue when it's on), you lose the security key that is associated with it and unfortunately we can't self-sign - this means if you use a function such as secure boot in UEFI mode, the card wont be allowed to boot.

Personally, I'd recommend flashing over the non-lit bios, you can still make it a UEFI compatible bios, however it wont be secure meaning no features such as secure boot or may make difficulties in some fast boot situations (though that's unlikely).

Eitherway, both bioses don't have any changes in clocks or power settings (I checked them myself some time ago, they are identical in their settings according to the fiji bios tool).

 

For me I dont use secure boot.
Right now on overclock I am helping with trying to see if my Nitro can have any shaders unlocked.

But since I am stuck at home from an accident yesterday, I may try Onnas bios he posted today.

 

My bad, i have changed description (i will on Main also) THX

 

You will be = :banana:

 

I have not tried it yet as I am trying to see if can unlock any shaders.

But if your bios gets me back to Fury X performance, Ill be excited.

 

You tell me
I don't have CPU (Yet) for proper testing.
