AMD admits to some borked ATI Radeon HD 4830sNot enough streams making their way into the channelBy Sylvie Barak: Monday, 27 October 2008, 10:22 AMAMD 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.
MY GOD at that OC... 21,000 plus in 3DMark06!!? WTF!!?As SOON as the price drop to <$350 US, ah buyin one...

to achieve higher clock speeds, but the approach wasn’t right. All they did back then, was to put batches of RV770 through binning, pick the best performing parts, and use it on premium SKUs with improved cooling. The attempt evidently wasn’t very successful: no AMD partner was able to sell graphics cards that ran stable out of the box, in clock-speeds they set out to achieve: excess of 950 MHz.
Final thoughts and ratingOftentimes we've lambasted multi-GPU graphics-card setups as a general waste of money, pointing our readers in the direction of the fastest single-GPU card that their budget allows them to buy.However, of late, both ATI and NVIDIA have cleaned up their multi-GPU acts, and scaling in popular games is such that adding a second GPU - be it on the PCB itself or via another card - makes implicit sense if the value proposition is just right.The sub-£100 Sapphire Radeon HD 4830 512MB validates this point by providing reasonable high-end gaming performance on its own but practically doubling average framerate when another is added.
So the sweet spot is supposed to be the 4850... but what do you say to 2x4830? you may think... nah... crazy... what if I told you it could best a GTX280? Hmm that might interest you Here's a quote:QuoteFinal thoughts and ratingOftentimes we've lambasted multi-GPU graphics-card setups as a general waste of money, pointing our readers in the direction of the fastest single-GPU card that their budget allows them to buy.However, of late, both ATI and NVIDIA have cleaned up their multi-GPU acts, and scaling in popular games is such that adding a second GPU - be it on the PCB itself or via another card - makes implicit sense if the value proposition is just right.The sub-£100 Sapphire Radeon HD 4830 512MB validates this point by providing reasonable high-end gaming performance on its own but practically doubling average framerate when another is added.Have a read: http://www.hexus.net/content/item.php?item=16300&page=1
I am certain by now arcman has no liver, no kidneys, 1 lung, 3.5 valves from he heart and only a small intestine.... O_o
