GamePC heeft een review klaar van de Tyan Tiger 133, een dual Slot-1 moederbord gebaseerd op de VIA Apollo Pro 133A chipset. Helaas is de plank erg brak uitgevoerd want hij was namelijk met geen mogelijkheid stabiel te krijgen :
I knew I was in trouble when the board repeatedly failed Windows NT and Windows 2000 installation with two processors, but once I took a single processor out, the system installed fine. This is a perfectly fine work around if you're using Windows 2000, but if you're installing Windows NT, it's a tough job getting the OS to load the multiprocessor kernel after the single processor kernel has already been installed. In Windows 2000, it's as easy as switching a driver in the OS, but unfortunately, we did our testing in NT.
Once inside the OS, stability was no better than before. The system would randomly freeze until I could get enough time to install the VIA 4.20 drivers in the system. Even with everything installed as it should be, it still wasn't as stable as any other SMP chipset I've used. Case in point, we couldn't run any 3D Studio or SETI tests, because the board would crash midway through our tests (these are quite long tests, 3-10 hours). We managed to wrangle out a set of Quake III SMP vs. non SMP benchmarks, but when we set Quake III to preform indefinite loops, it crashed within an hour.
Update : We tried multiple Tiger 133 boards, they all had these problems, not just a single bad board.
