that'll be memory bus speed (266MHz effective). pci bus is only ever 33MHz (unless you overclock it but even then you wont get it over 40MHz afaik). if
your controller is on the IDE bus then its maximum sustained bandwidth must be 33MHz * 4 (32 bit bus) or * 8 (for servers with 64 bit PCI). which 132 Mb/s maximum transfers for all devices on the PCI bus. AGP is a separate bus and runs at 66MHz standard so shouldnt interfere with PCI bus transfers. as for the 266 speed of your memory bus, that'll be it sending on the rise and fall of the clock signal so you get twice the transfer rate (ie. DDR for Double Data Rate). ph. ----- Original Message ----- From: "Nick Lankester" <[EMAIL PROTECTED]> To: "Drum & Bass Arena Discussion List" <[EMAIL PROTECTED]> Sent: Monday, December 10, 2001 2:50 PM Subject: [dnb-prod] Re: Computer Check: Need your advice > Yeah, the bus speed on my MB is 266...
