* KX133 Chipset: The FSB of current Athlons (K7) should not exceed 100 MHz (x2 or Double Data Rate). The clock rate of 133 MHz for the memory interface is produced by an addition of FSB and PCI clock.
** beyond 'official' specification, AGP divisor is locked at 2/3 of the system bus, i.e. the AGP bus runs at 88.8 MHz when the FSB is 133 MHz, default would be 66.6 MHz Bus System, also referred to as Front Side Bus (FSB)

Memory Interface
EDO Extended DataOut or Hyperpage Mode of Asynchronous DRAM
FPM Fast Page Mode (memory without Column Address Setup Time)
SDR Single Data Rate
DDR Double Data Rate
SDRAM Synchronous Dynamic Random Access Memory
RDRAM Direct Rambus Random Access Memory
PC100 Clock is max. 100 MHz x 1 x 8 Byte equals to max. 0.8 GByte/s data throughput, short latencies
PC133 Clock is max. 133 MHz x 1 x 8 Byte equals to max. 1.1 GByte/s data throughput, short latencies
PC266 Clock is max. 133 MHz x 2 x 8 Byte equals to max. 2.2 GByte/s data throughput, short latencies
PC600 Clock is max. 266 MHz x 2 x 2 Byte equals to max. 1.1 GByte/s data throughput, long latencies
PC700 Clock is max. 356 MHz x 2 x 2 Byte equals to max. 1.4 GByte/s data throughput, long latencies
PC800 Clock is max. 400 MHz x 2 x 2 Byte equals to max. 1.6 GByte/s data throughput, long latencies
AGP Bandwidth
n/a in this case only PCI slots (132 MByte/s) are supported
AGP 1X dedicated graphics card bus with a max. transfer rate of 266 MByte/s
AGP 2X dedicated graphics card bus with a max. transfer rate of 528 MByte/s
AGP 4X dedicated graphics card bus with a max. transfer rate of 1 GByte/s
IDE (ATA) Interface
UDMA66 max. HDD transfer rate of 66.6 MByte/s using bus mastering (minimizes CPU utilisation)
UDMA33 max. HDD transfer rate of 33.3 MByte/s using bus mastering (minimizes CPU utilisation)
PIO4 max. HDD transfer rate of 16.6 MByte/s not using bus mastering (leads to strong CPU utilisation)
