I have to say, even though this was already posted, this is a great editor. And I wouldn't have known about it from the other thread.

It does not do checksum it appears, and looks like no memory voltage adjustment. Will it work on the 2900 cards? If not, they should make it so it does. The bios layouts are almost identical.

:rofl: no checksum = pain in the ass, you still have to edit it manually with some hex editor to get it working.

I wonder how many n00bs are gonna RMA their cards thinking it's dead after flashing an edited BIOS without the correct checksum :rofl: :ROTF: :up:

Die erforderliche Checksummenkorrektur führt das Programm automatisch beim Speichervorgang durch. Somit entfällt das lästige Ändern entsprechender Bytes mit dem Hex-Editor.

The necessary correction of the checksum is done automatically while saving. Therefore there is no need to change the bytes via a Hex-Editor

interesting program! too bad I don't have a HD-3870 :D hopefully it'll support future AMD-cards as well :)

:woot: is there a windows bios flash tool as well now or do we have to use our floppy drives or boot from cd into dos again? :D

Its does the checksum and the X2 flashes fine.

I'd personally stick to DOS. And try a USB flash drive as a boot drive, works no problem.

I can confirm it works like a charm with HD3870, with corrected checksum and Overdrive enabled :yepp:

Teach me how to make my USB flash drive bootable.
My motherboard supports it, don't worry about that.

I guess this means I should work harder to get the full BIOS Editor out.

you.

I tried the HP method once before, and I didn't have much luck, but I am sure it was my fault.

Here is a screen shot of my current BIOS Editor. (Depressingly, no core or memory clock editing yet).

Is this a good substitute for pencil vmods?
For instance, can we push the vcore for higher values than default safely?

Can we push 3870s to 1Ghz with proper cooling using just a modified bios?

nope.

1.324 is the highest the bioses go.
I havent seen any that go any higher.

My 3870 does 850Mhz at 1.214V:

I am hoping that with an unlocked and edited BIOS for 1.3V, and an Accelero S1 Rev 2 I can reach over 900Mhz. I will need this editor to make the changes needed.

the PWM of the cards aren't built to deliver more than 1.3v juice, iirc. so only hard mod / pencil mod will get you higher.

author of ati tool w1zzard said its possible to manage voltage for 3870X2 by software way, even more then on 3870.
