133 (266) FSB Athlon

[Mean MrMustard]

The new Athlon will support the 133 Mhz FSB for the KT133A motherboards. So why do people talk about a 266 Mhz FSB? Is that only on the DDR motherboards? I originally got the idea that the only difference between the DDR motherboards and the KT133A boards was that KT133A doesn't support DDR ram.

The bus is still ddr whether it's interfacing with sdr or ddr memory is irrelevant.

Thanks for clearing that up for me, I got confused with the DDR.

It's just like how the current Athlon runs on a 100MHz DDR bus, which is 200MHz effective.

I took this exerpt from Mortin's review of the KT7A http://www.icrontic.com/?action=hardware&id=41

"Since the KT133A chipset still uses the DDR EV6 bus, the FSB runs at an effective 266MHz. This is 2.1GB/sec of bandwidth, folks. The KT7A also uses the new 686B Southbridge with ATA/100 support."

"The KT7A will work with both original 100MHz FSB Athlons and the new 133MHz FSB Athlons. The beauty of this board is it's in-BIOS multiplier manipulation. If you have a current 100MHz FSB Athlon, you can simply decrease the clock multiplier (assuming you unlocked the chip), and increase the FSB. This is done while keeping the default 33MHz PCI speed. This is thanks to the VT8363A North Bridge Controller"
