XLR8 Tech Support FAQ - MAChSpeed G3Z
- I've installed a MAChSpeed G3Z and my machine will not boot. What do I do?
Make sure you configured the ZIF jumpers correctly. Check to see that the MAChSpeed G3Z is properly seated in the connector. Also be sure that all your RAM is seated firmly and is rated at 60 nanoseconds or faster. If your Mac still won't boot, check the manual and be sure that all jumpers and dip switch settings are set correctly to run the card at it's stock, rated speed.
- Since upgrading I am getting strange artifacts on my screen and occasional system freezes. What is causing this?
You may be running the processor or bus speed too fast. Be sure that the card is set to stock settings. Running the system too fast can cause artifacts and freezes. You may also have a VRAM problem. Also check your extensions and control panels. In some cases problems are due to software conflicts.
- I was running my ZIF over-clocked, but due to crashes, I returned it to normal speed. It still crashes, has my card gone bad?
No. Chances are your card is fine. First make sure your crashing was not caused by a virus. If not, then, the problem is extremely likely that the crashes while running over-clocked have corrupted your hard drive. Reformat and reinstall, everything.
- Are there any incompatibilities with the MAChSpeed G3Z?
The MAChSpeed G3Z is fully compatible with a wide array of audio editing hardware, particularly Digidesign. The current version of the XLR8 MAChSpeed Control software, 1.4.3, allows utter compatibility with MacOS 9.0.4, Adaptec SCSI boards, and Dantz Retrospect. Compatibility with Media 100 has also been resolved, as has been compatibility with Retrospect and ADAPTEC SCSI products. With the release of the XLR8 MAChSpeed Control software, OS X Server compatibility has also been resolved.
- Prior to installation, should I remove my external L-2 cache, 256K, on my 7500? If not, and the L-2 cache remains installed, would performance increase if I upgraded the L-2 cache to 1 MB?
The L-2 cache becomes an L-3 cache when the G3 upgrade is installed.
Best operation and performance is with the L-3 cache removed.
- I have followed seemingly all the instructions to properly run my upgrade, but I still get random freezes when using certain applications. What else can I try?
We have linked several instances of random freezes to the Font manager font corruption issue in the Mac OS 8.6. Apple has posted a fix at <http://asu.info.apple.com/swupdates.nsf/artnum/n11489>
- I seem to be experiencing some conflicts since installing my ZIF upgrade in a Mac equipped with an ATI video card. Is there a fix?
There is a timing issue between the ZIF upgrades and the ATI video that can cause instability. It is advised that anyone adding a ZIF upgrade to a beige G3 or G3/BW should first install the ATI Video Software Update Version 1.0. Apple has addressed this problem with the update.

- I'm experiencing some odd behavior since overclocking my MAChSpeed G3z. Is there any way to see if my speed setting is the problem without opening up my Mac?
While it is always best to manually adjust the speed of your MAChSpeed G3z, you may try a third party Control Strip module called the G3 Throttle.
This control strip allows people to slow their card down by introducing wait states between instruction packets sent to the CPU.
