*KT266 contains a hardware bug which cause system instability when using the AGP slot at the specified max capacity of 4x. [cite web|title=WaveTown - For : VIA-based motherboard owners and 4X AGP-based graphic cards ...|url=http://wavetown.net/forums/archive/index.php/t-76493.html 070808 wavetown.net]
*"ProSavage KM133, KM266, KM400, KM400A" - Similar to the above, but with integrated graphics. After KM133, DDR is supported. The KM133 uses an IGP consisting of the S3 Savage4 3D core and Savage 2000 2D functionality. KM266's ProSavage8 IGP is similar but has an additional 3D pipeline. The KM400 chipset and its "A" variant use the VIA UniChrome IGP.

* VIA K8T800, VIA K8T800 PRO, VIA K8M800 - Athlon 64 chipsets. Established an early market lead, with richer features, and a full speed HyperTransport implementation

* VIA PT880, PT880 Pro, PT880 Ultra, K8T890, K8M890, PT890, P4M890, PT894 - Via's first PCIe IGP chipsets (Pentium 4, Athlon 64), DDR/DDR2 memory, built-in UniChrome Pro video, 533MB/s VIA V-Link interface

* VIA PT900, P4M900, K8T900, K8M900 - VIA's PCIe-only chipsets. The P4M900 and K8M900 have onboard graphics. The PT900 and P4M900 chipsets have single-channel DDR2-only memory controllers, while the K8T900 and K8M900 being Athlon 64 chipsets do not have memory controllers.

* *SATALite interface allows for two additional SATA devices (4 total). It is required for RAID 0+1 on VT8237R Plus.
* Motherboards frequently had VIA companion chips for added functionality such as better audio (8 channel), more/faster USB (i.e. USB 2.0 for VT8233), or Gigabit Ethernet.
