Model Info
The 230, 330, and 550 models are essentially standard PCs and have the same capabilities and upgrade limits as other PCs of the time. The 230 and 330 are based on VIA chipsets, used socket 370 processors, and conventional SDRAM. The 550 used Slot 2 Xeon processors, the Intel 840 chipset, and RDRAM. The video cards these systems used are Nvidia AGP cards based on the Quadro 2 chipset, and differ from aftermarket Quadro GPUs in their drivers.
