AMD admits to some borked ATI Radeon HD 4830s

Not enough streams making their way into the channel

AMD HAS ADMITTED some of its ATI Radeon HD 4830 boards only have only 560 of their advertised 640 stream processors enabled, some even making their way into the channel.

After collecting performance data on the boards, Bit-Tech noticed some of the numbers just weren’t adding up. Apparently, after being fobbed off by AMD a couple of times with lame excuses, with the firm even trying to blame the software used to calculate the number of stream processors, the chipmaker finally came clean and issued a statement about the problem.

AMD admitted that, as well as the sample boards sent to the press for testing, a "limited number" of ATI Radeon HD 4830 boards with a performance impacting pre-production BIOS were also released to market. The firm claims this "limited number" comes to about 400 boards from AMD partner HIS.

"This is in no way hardware related, and an updated BIOS fully resolves the performance limitation," the firm said, adding that any punters who bought an HIS board should get it tested using the GPU-Z utility. If it turns out that less than 640 shaders are actually up and running, AMD recommends users go to the HIS website where they can pick up information on how to download an update for the card's Bios. µ
