Default clocks for 4870 are 750MHz / 900MHz while the ASUS TOP bios is 815MHz / 925MHz and the ASUS BIOS has fixed the annoying low fan speed bug in other 4870 bios's

Sweet! Nice thread.

Sweet bro! Keep 'em coming

Kudos Guruman :D

I have used ATI flash and RBE to flash my 4870x2's. One thing to remember withh the x2's is there are 2 bios's for the x2's.

yup master and slave bios, when i first flashed my card to the top bios i flashed the bios backwards master to slave and slave to master :)

needless to say it didnt work!

had to re flash through DOS with the correct bios :)

Well... It was sounding pretty easy until I got to this post LOL!

I have 2 4870 x2's that I will need to do... What do I expect when I go to flash them and what is the correct way? I hate working in DOS!!:argh:

Also.... In the instructions it says to go to the link and download the ASUS top bios which is a .bin file, and then it says to go to the link and download the RAR package which contains the asus.rom.

So are the asus.rom and the asus top bios.bin the same thing, or will I need them both?


EDIT: I did everything it says to do for preparing the USB flash drive, all files are on there and I hit F8 to boot from the USB drive. It then takes me to a black screen with a blinking cursor but thats all it does... I can't type anything and it just sits there and blinks? Anyone have any input on this?

bump :D

V2-V3 gets busy from time to time. PM hellcamino, he's done this before
