My system was rock solid running 10.4.3 before the cpu install. The GD dual 1.8 booted up like a champ in both X, and 9.2 (on a separate partition, separate hard drive) after installation.tw_247 wrote:i definitely recommend GD- their tech support is great, and so are their products.

I had to make a jumper cable adjustment on my Giga to give "Tiger" more 'juice'.
A few days later, a program crashed. Eventually, over the next few days, all apps were crashing. I did a backup/clean install with the same pattern. I discovered that 10.3.9 did not crash. (The side benefit of all this backup and clean install business is that I can now do it with a high degree of confidence: either to restore a previous system, or move ahead problem-free with the new install).
Tim at Giga gave me a instructions to alter the factory default voltage jumper settings on the 7447A cpu: 1. try increasing voltage to the next highest setting, 2. if that doesn't work, try the next lowest... His first suggestion cured the problem. (I'm my case, going from 1.45v to 1.5). Tim said that Tiger requires more voltage than Panther or OS9.x. Insufficient voltage was causing system instability.
The voltage jumpers are pairs of pins (to the far right of the dip switches) with tiny plastic jumpers on some of them, off on others. I needed to use a magnifying glass to get the job done. You really shouldn't mess with these unless Tim instructs you to.
GD performance and tech support has been outstanding!!!
