Radeon Bios Editor
Ciao a tutti, girovagando su TechPowerUP! ho scovato questa nuova utility:
RBE is a tool which helps you over-/underclocking and tuning your recent ATI video card. Unlike other programs as Rivatuner for example, RBE will provide a modified version of your video card's original BIOS that you can flash upon your video card. Although flashing a BIOS is always somewhat risky, this method has some advantages:
- Many video cards are supported. See section ii) for an uncomplete list.
- You don't need to run an overclocking tool on every windows startup.
- You can modify the GPU's voltage using RBE, which simple software-OC tools are not capable of.
- Overclocking is no more dependent on windows. It works with every operating system like Linux, Mac OS and so on...
- RBE can help with the fan settings on 29x0- and 3850/3870 cards.
- You can modify every state your video card has, even the clocks during boot up.
- So you can underclock/undervolt your card during boot up and in 2D-Mode to save power (and thus money) and to allow your card's fan to run slower (and thus more silently).
With RBE, you can load your video card's BIOS, change some values and save the new BIOS file. RBE will automatically fit the BIOS' checksum so ATIFlash or WinFlash will not complain about a not matching BIOS image file.
ii) Which video cards are supported?
The program was originally built to support my HD 2900 pro 512 MB 256 bit, so this card is supported, of course. Later on, after some requests, I added support for HD 2900 pro 512 bit, HD 2900 XT, HD 2900 GT and HD 2600 XT, each regardless the video memory configuration. I also tried some HD 2600 pro and 2400 XT BIOS files, they are supported as well.
Furthermore, 3450, 3650, 3870 X², 3850 and 3870 cards are supported. For 29x0 and the last two cards there is a fan control setting in RBE.
All in all, the engine is somewhat flexible. If you have a video card which is not officially supported, just give it a shot nevertheless. It might work. And if not, send me a request. In most of the cases, it's easy to add support for a card.
Note that some status reports on the BIOS file are being displayed. These and some internal methods more help RBE to verify the validness of the processed BIOS image file. This leads to a high level of secureness. However, tinkering with BIOS flashing is never without any risk. Neither RBE's author, nor any of the people associated with it, can be made responsible for any damage caused.
You can see that numerous video card types can be selected in the drop down menu on top. After doing that, you load your BIOS file. Be sure you use original BIOS files that are not pre-modified only. BIOS files already modified with RBE can not be loaded again with RBE due to safety reasons.
Then the default clock settings are being displayed. Change any values you like and save you file after that. This new file can be flashed onto your video card. Always be sure that the file's checksum is identical to the checksum of the current BIOS on your video card.
There's a program internal FAQ section.
If you have a question, refer to this at first. If your question is not properly answered here, you can send me an eMail to the address found in the "About" section.
iii) Installation
There is no installation required. Just download the RBE.exe and run it. There is just that one single file. No administrative privileges are required to run RBE, whether you use Windows XP or Vista.
