Re:Radeon HD 4xx0 series BIOS's, we want these, big thank you! - 2008/08/02 11:46Found an newer version of the Radeon HD 4870 BIOS, meaning version 113-B50701-105. First tests on a regular Radeon HD 4870 show that a considerable power reduction in 2D can be achieved with the voltage and memory frequency switching supported in this BIOS. ATI Radeon HD 4870 512MB Standard Edition - Memory : 512MB - Bus Type : PCI Express
