Forum user BAGZZlash from TechPowerUp has recently released a new and significant update to his alluring Radeon BIOS Editor utility, more commonly abbreviated as RBE.

In perspective, the software tool is essentially a convenient way to flash a custom BIOS to any Radeon HD-series desktop GPU with user-defined voltage adjustments and frequency settings. Unlike conventional approaches to tweaking that are available in RivaTuner and similar applications, RBE facilitates seamless GPU BIOS adjustments including the manipulation of voltage registers on Radeon GPU, making real software voltmods a possibility.

The latest release adds a full list of Radeon HD 5xx0 device IDs and now officially supports the HD 5670, HD 5750, HD 5770, HD 5850, HD 5870, and dual-GPU HD 5970. In addition, it fixes a GetStringPos" bug that occurred on rare BIOSes and improves RAM and RAM interface detection.

Unfortunately, there is still no voltage tweaking ability for Radeon HD 5000-series cards, but we can be assured that this will probably come in the next release.

RBE 1.23 can be downloaded here.
