  • ProSavage PM133 - Graphics core from S3, derived from a combination of the 3D component of Savage4 and 2D from Savage 2000.
  • PLE133 and PLE133T - Graphics core from Trident, derived from Blade3D.
  • CLE266 - Graphics core from S3, derived from S3 Savage series under the brand name UniChrome.
  • Asus advertised some boards as Apollo Pro 133Z.[7] 133Z appears to be a late revision of or step up from 133A, but it is not listed on the VIA site.

  • KT266 contains a hardware bug which causes system instability when using the AGP slot at the specified max capacity of 4×.[20]
  • ProSavage KM133, KM133A, 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.
  • Later revisions of the KT333 (sometimes called KT333CF) are rebadged KT400 chips with AGP 8x disabled. On motherboards with this chipset AGP 2x cards which require 3.3V are not supported.
  • KT133E (= VT8363E + VT82C686B) appears on Gigabyte 7IXEH [21] but is not listed on the VIA site. Based on the specifications of that motherboard, KT133E appears to be equivalent to (or a cost-reduced rehash of) KT133, supporting 133 MHz for memory but only 100 MHz for the CPU.
  • Some revisions of KT333 support 166 MHz FSB.

Athlon 64

  • VIA K8 series – Athlon 64 chipsets. Established an early market lead, with richer features, and a full speed HyperTransport implementation
  • VIA PT890, P4M890, PT900, P4M900, K8M890, K8T890, K8T900 – VIA's PCIe-only chipsets. The P4M and K8M chipsets have onboard graphics VIA UniChrome Pro.
  • The Athlon 64 chipsets do not have memory controllers, because memory controller is integrated into the CPU. Supported memory types depend on the CPU and socket used.

Pentium 4 Northwood / Prescott

  • Being a reduced version of PM880, PM800 is not as closely related to PT800 as P4M890 to PT890. Because of its high cost, It is soon obsoleted in favor of P4M800 and then P4M800 Pro, both of which have a lower rated V-Link and feature no special memory technology such as FastStream64 or StepUp that is common in the other listed 8xx chipsets.

  • *SATALite interface allows for two additional SATA devices (4 total). It is required for RAID 0+1 on VT8237R Plus.
  • The SATA-II feature of VT8237S is limited to 300 MB/S Data Transfer Rate bearing no NCQ functionality.
  • 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.
  • 8233: while AC97 could help offer a fau modem, this feature is not "on the board" and (some) boards did not come with a modem connector bought from store in box
  • 8233: manual does not mention 3com 10/100 at all and there is not connector - I believe the citation above to be possibly made by someone who does not have 8233

As a modular solution, the North and South Bridge of the VIA Apollo KT266A are completely pin compatible with current and future products, such as the VT8233C South Bridge with integrated 3Com Ethernet MAC.

Hardware bugs

The KT133 chipset corrupted disc subsystems. Specifically, the 686B Southbridge had issues with Creative's SBLive! sound cards. A BIOS update was released by VIA to fix this issue, however it is not known if all motherboards with 686Bs had their BIOSes updated.[66][67][68][69] The KT266 contains a hardware bug which cause system instability when using the AGP slot at the specified max capacity of 4×.
