Since the first video card radeon HD 2900 Pro were easily overclocked to the radeon HD 2900 XT level , many asked about the possibility to use the radeon HD 2900 XT Bios in radeon HD 2900 Pro?
xtremeSystems.org members already checked this question . Let us note that the purchased video card radeon HD 2900 Pro from sapphire originally had BIOS from Radeon HD 2900 XT.
The radeon HD 2900 Pro overclock without any modifications to many owners was to the frequencies more than 800 MHz on the video chip, the memory reach 2000 MHz DDR in most case . Flashing the card with a BIOS from Radeon HD 2900 XT do not cause any problem, video card begins to work on typical for Radeon HD 2900 XT frequencies normally. Let us note that the BIOS from Radeon HD 2900 XT contains higher latencies, which facilitate the memory overclock to higher frequency. Video card BIOS from Radeon HD 2900 Pro at the same frequency has more aggressive latencies, which result in higher operation speed .
Thus, if your video card radeon HD 2900 Pro is accelerated rather well, THERE ARE NO special sense to flash it with Radeon HD 2900 XT BIOS - this operation will only set higher latency and will lower the video card speed.
