      Today MacMan updated Chimera to version 1.9. The most exciting change is the addition of a new bit of GraphicsEnabler code from the Chameleon team to enable multiple NVIDIA graphics cards without any extra DSDT edits necessary! He's also added support for Intel's soon to be released Ivy Bridge CPUs and GraphicsEnabler detection for NVIDIA's new GeForce GTX 680. This new version will be included in the next MultiBeast release.

       
      Chimera v1.9 Changes:
      • Back-ported the following Chameleon commit:
        • r1903 "NVDA,Child" device_type support for non-primary NVIDIA cards.
        • Multiple graphics cards work without any extra DSDT edits.
      • Added support for Ivy Bridge CPUs.
      • Added GraphicsEnabler detection code for NVIDIA GTX 680 and GT 620.
        • Driver support is still missing in Mac OS X.
      • Added additional missing NVIDIA cards.
      • Added GT540M device id 0x0DF4 to memory detection work around.
      • Cleaned up Sandy Bridge-E CPU detection and support code. 
        NOTE: Proper drivers are required for full graphics support.
          There is a standalone installer, available at tonymacx86.com/downloads. For bug reporting, feature requests, and general feedback please use the Chimera forum.

          Exclusive: Intel's Unreleased Ivy Bridge Core i7-3770K Running Mac OS X Lion

          Well it's official- Mac OS X Lion runs great on Intel's upcoming Ivy Bridge platform. Here's a few screenshots of the Core i7-3770K running at stock 3.5GHz on a Z77 motherboard submitted to us via an anonymous tip:

           
          Because there are no Macs yet with Ivy Bridge, the tipster had to use a modified kernel to boot. We can't wait to test out these chips to see what else they can do. Intel's official release date for Core i7 and Core i5 desktop CPUs is April 29th. Check out the Hardware News and Rumors section of the forum for more information on upcoming products.

          Optimizing NVIDIA GeForce 4xx and 5xx Graphics Cards for Mac OS X Lion Using OpenCL and CUDA


          Many graphics and video professionals prefer using NVIDIA graphics cards. OpenCL (Open Computing Language) was initially created by Apple to provide applications access to the computing power of the graphics card as well as the CPU. This can dramatically increase the general performance of high-end applications at the OS level, and has become an industry standard. Apple has supported OpenCL since Mac OS X 10.6 Snow Leopard.

          Using the latest MultiBeast, all NVIDIA 4xx and 5xx graphics cards can be optimized for Mac OS X Lion. We've included a Combo OpenCL Enabler, that not only patches all device IDs into the native driver, but patches the system to use the power of OpenCL. Earlier NVIDIA (pre-Fermi) models and ATI/AMD cards are OpenCL enabled by default, and do not need any patching. Integrated graphics solutions such as Intel HD 3000 do not support OpenCL.
          How to Enable OpenCL for NVIDIA 4xx and 5xx Graphics Cards:

               1. Update to the latest version of Mac OS X Lion
               2. Download MultiBeast
               3. Run Combo OpenCL Enabler
               4. Reboot

          NOTE: Only for Mac OS X Lion native drivers with NVIDIA 4xx and 5xx cards. If you've previously installed the official Quadro for Mac drivers for Lion from NVIDIA's site, do NOT run the Combo OpenCL Enabler.


          NVIDIA has created a similar but proprietary technology, called CUDA. According to NVIDIA's site, CUDA is "a parallel computing platform that enables dramatic increases in computing performance by harnessing the power of the graphics processing unit (GPU)". NVIDIA's CUDA driver for Mac can be downloaded free from NVIDIA's site here.
          It is important to note that both CUDA and OpenCL don't work with every piece of software. The application itself must be coded to support them. Refer to the developer's website for compatibility with these technologies.

          Below are some of our top picks for modern NVIDIA cards that can be fully enabled using the new Combo OpenCL Enabler and CUDA.
