Download the latest drivers for your SAPPHIRE Radeon consumer graphics card product and operating system. Also note that most AMD drivers are universal and backwards compatible however they are operating system specific. Always make sure you choose the appropriate operating system for your computer, although the latest drivers should be compatible with most GPUs from previous generations.
Testing of new AMD (Formerly ATI) Radeon HD 68XX series video cards will consist of running the cards through the OverclockersClub.com suite of games and synthetic benchmarks. This will test the performance against many popular competitors. Comparisons will be made to cards of equal and greater capabilities to show where these card's performance stands. The games used are some of today's newest and most popular titles to give you an idea on how the cards perform relative to each other. The system specifications will remain the same throughout the testing. No adjustment will be made to the respective control panels during the testing, with the exception of the 3DMark Vantage testing where PhysX will be disabled in the NVIDIA control panel. I will test the card at stock speeds, then overclocked in order to see how much additional performance is available and to determine if it can run with the current fastest single GPU cards on the market. The drivers used in this test will be the 10.9 Catalyst drivers for the old ATI lineup, the latest launch driver for the HD 68XX series and 260.89 Forceware drivers from NVIDIA for the GTX 480, 470, 465 and GTX 460 and 450. Tests will be conducted at both stock and overclocked settings to gauge performance when an increase in clock speed is applied.
Xfx Radeon Hd 6850 Drivers For Mac
Overclocking the HD 68XX series cards from Sapphire, XFX, and PowerColor was much the same as overclocking the AMD HD 5XXX series cards. By increasing clock speeds, performance gains in benchmarks are to be expected. To reach the maximum clock speeds on each card I used MSI's Afterburner overclocking utility to get the most from each card. The configuration file was modified to to allow clock speeds above what is listed in the AMD Catalyst Control Center, just in case I needed it. On the Sapphire card, I was able to reach 974MHz on the new Barts core and 1179MHz on the GDDR5 memory. That's an increase of only 8%, or 74Mhz, on the core and 129MHz, or close to 12%, on the memory - without any added cost. The XFX version of the HD 6870 did better on the core, but was slightly worse on the memory, at 1000Mhz on the core and 1166MHZ on the memory. These increases are roughly 11% on the GPU core and 10% on the memory. The PowerColor card was also able to achieve an 11% gain on the core speed, up from 900 MHz stock up to 1000 MHz overclocked. The memory was able to be pushed all the way to 1220 MHz from 1050 MHz stock for a gain of roughly 16%, the highest memory clock of the group. Last but certainly not least, the HD 6850 from XFX really was able to maximize the GPU clock speed from its original 775MHz to 972Mhz, just shy of a 200Mhz increase on the core. The memory seemed to fall right in the narrow window all of these cards fall into. While not has high as what the HD 5XXX series were capable of, the clock speeds are impressive enough to really push the performance envelope that one step further.

The hardest part was to build a bootable Windows on USB. I've tried to save a previous Win8.1 BootCamp, but failed. I've tried to use Winclone, and even injected drivers as described, but than just couldn't boot. I had to set BootDriverFlags to 28 via regedit (see this forum for solution), but still couldn't boot.
I was looking for the cheaper ADT-Link R43SL adapter option, as this is a for fun / budget build. As the price depends on cable lenght, I' ve choosen 25 CM option, which turned out to be short for even 13', I had to flip it to lying on its display (it was easier to make the operation this way), see pics. One would go to 40-50cm for a more elegant build, and might be able to partly close bottom case. Keep in mind, you'd need special screw drivers for newer macs.
Codenamed Barts, the Radeon HD 6800 series was released on October 23, 2010. Products include Radeon HD 6850 and Radeon HD 6870. Barts uses shaders of the same 5-way VLIW architecture as HD 5000 series.[8] 2ff7e9595c
