Asus 5870 v2 BIOS on Ref Sapphire 5870?

post #1 of 4
Thread Starter 
Hey Guys,

Im new to the whole BIOS flashing thing but I have read up up fair bit but want to confirm something.

At the moment I am running a Asus 5870 V2 with stock cooling and a Sapphire 5870 With a EK Full Cover waterblock.

My problem comes in when I want to OC. The Asus card's voltages can only be changed in Smart Doc and clocks I use MSI afterburner (left and right key precision). The Sapphire one can be overclocked and over volted in MSI Afterburner but it is locked at 900/1300.

Now I have tried to go into msi afterburner and change unofficial OC'ing to 1 but when I try to change clocks above 900/1300 then it stays at 900/1300.

I have herd that certain Sapphire cards can only go above the 900/1300 mark but need a ASus or MSI bios.

So this is where it gets tricky because I found this thread which tells you how to unlock the Sapphire ones BIOS to a Ref Asus BIOS which should work fine with me.

My question is, can I flash my 5870 V2's BIOS onto my Sapphire card and if I do and it doesn't work can I flash the stock one back and start from scratch?

The Asus 5870 V2 is non ref and the Sapphire one is ref, I know this because I am thinking about ordering a 5870 V2 block and its different from the ref one.

Here are pics of both the PCB's:

The main reason for me wanting to put the 5870 v2 BIOS on is because then they will both be the "same" card according to windows and might scale slightly better.

Please let me know guys smile.gif

never flash a reference card witha non reference BIOS and vice versa you will brick the card you could try one of the reference BIOSes link to BIOS page on TPU
