Hi All
I have a MacPro 2x2.66 Ghz Dual Core Intel Zeon with 4Gb 667 Mhz DDR2 FB-DIMM running 10.5.6
I have a 20' ACD and a HP L1702 screen attached being driven by a NVIDIA GeForce 7300 GT.
Occasionally the HP screen flickers with a purple colour cast, it seems to happen more when viewing java intensive web sites or if I am editing in Photoshop CS3, although it does happen on other occasions, just I have never related it to other apps. I have not noticed any issues with the 20'ACD which is regularly colour balanced.
When Snow Leopard was released, I upgraded my two MacBooks without issues, but on trying to upgrade the MacPro all went well until the final reboot and the screen(s) just cycled through showing the working desktop, then dark blue, then black and back to the desktop for a few seconds. I went through all the possible update combinations including a clean install. The problem still persisted.
In the end I decided to revert back - it was possibly linked to issues with the graphics card and resolution.
I am now in the situation where I need to upgrade to Snow Leopard and the purple casting on the HP screen is getting worse.
Are the two problems linked (ie. the colour casting & SL upgrade issues)?
What is the recommended replacement card and will this cure both issues?
I have posted the relevent info below.
Many thanks for all advice etc.
Simon

WWDC 2006, SAN FRANCISCO—August 7, 2006—Apple® today unveiled the new Mac® Pro, a quad Xeon, 64-bit desktop workstation featuring two new Dual-Core Intel Xeon processors running up to 3.0 GHz and a new system architecture that delivers up to twice the performance of the Power Mac® G5 Quad*. With advanced performance, greater expansion, higher performance graphics options and unprecedented customization, the newly designed Mac Pro is the ideal system for the most demanding user. The introduction of the Mac Pro marks the completion of a rapid and seamless transition for Apple, with the entire Mac family now using Intel’s latest processors.

“Apple has successfully completed the transition to using Intel processors in just seven months—210 days to be exact,” said Steve Jobs, Apple’s CEO. “And what better product to complete it with than the new Mac Pro, the workstation Mac users have been dreaming about.”

The new Mac Pro features the new Dual-Core Intel Xeon 5100 series processor based on the revolutionary Intel Core microarchitecture, delivering breakthrough performance and power efficiency. The new Mac Pro is up to twice as fast as the Power Mac G5 Quad running industry standard benchmarks and features two Dual-Core Intel Xeon processors running up to 3.0 GHz, each with 4MB of shared L2 cache and independent 1.33 GHz front-side buses. With 667 MHz DDR2 fully-buffered memory, the Mac Pro also boasts a 256-bit wide memory architecture for amazing bandwidth.

With more than 4.9 million possible configurations, the Mac Pro delivers unprecedented customization to meet even the most demanding performance, expansion and storage needs. The newly redesigned Mac Pro features an all new, direct attach storage solution for cable free, snap in installation of up to four 500GB Serial ATA hard drives for a total of 2TB of internal storage—the most ever on a Mac—and support for two optical drives to simultaneously read and/or write to CDs and DVDs. Every Mac Pro includes three full-length PCI Express expansion slots and one double-wide PCI Express graphics slot to support high-powered, double-wide graphics cards without sacrificing multiple slots. Providing quick and convenient access to connect the most popular external devices, the front panel of the Mac Pro includes a FireWire® 800 port, a FireWire 400 port and two USB 2.0 ports with additional FireWire 800, FireWire 400 and three USB 2.0 ports on the back panel. Mac Pro also includes dual Gigabit Ethernet ports, optical digital input and output, analog audio input and output, and optional built-in support for AirPort® Extreme and Bluetooth 2.0+EDR.

Every Mac Pro comes standard with the NVIDIA GeForce 7300 GT with 256MB of video memory, providing built-in support for dual-displays and Apple’s 30-inch Cinema HD Display. The ATI Radeon X1900 XT and the NVIDIA Quadro FX 4500, both with 512MB of video memory, are available as build to order options and provide built-in support for up to two 30-inch Apple Cinema HD Displays. The Quadro FX 4500 also includes a stereo 3D port to connect goggles for stereo-in-a-window applications and is ideal for the most demanding animation, special effects and scientific visualization applications. The Mac Pro supports up to four PCI Express graphics cards to drive up to eight displays at once for advanced visualization and large display walls.

The latest release of the world’s most advanced operating system, Mac OS® X version 10.4.7 Tiger, comes with every new Mac Pro, including Safari™, Mail, iCal® and iChat AV, running natively. Tiger includes an innovative software translation technology called Rosetta® that lets customers run most Mac OS X PowerPC applications seamlessly.** Intel-based Mac customers have more than 3,000 Universal applications to choose from including all of Apple’s own consumer and professional applications. Universal Mac software includes versions of Xsan®, a high performance, enterprise class Storage Area Network (SAN) file system and Mac OS X Server, Apple’s award-winning server operating system. An updated list of Universal applications for Mac OS X is available at guide.apple.com/universal and is growing each day with hundreds of developers announcing support for Mac OS X Intel-based applications.

Apple’s award-winning widescreen flat panel Cinema Displays offer the perfect match for the Mac Pro and are now more affordable than ever. The 30-inch Cinema HD Display with an industry-leading 2560-by-1600 pixel resolution and the 23-inch Cinema HD Display with a 1920-by-1200 pixel resolution, ideal for editing High Definition Television (HDTV) content, are now priced at $1,999 and $999, respectively. The 20-inch Cinema Display is now just $699 and offers a 1680-by-1050 pixel resolution, more than enough space to edit full size images with plenty of room for on-screen palettes.
