AMD 1.4Ghz & 266mhz FSB

[rodan]

I put an AMD 1.4mhz, 266 mhz bus, into an ECS K7SEM board. I installed Kingston 133mhz cas 3 memory. The K7SEM board has the SIS 730 chipset in it. When I booted up, the bios automatically configured the cpu at 1.050 mhz. I went into the bios and manually set the cpu host to 133, the memory to 133, and pic clock to 33mhz. THe computer then booted to run the cpu at 1400C. The computer runs fine, no problem, no crashing, ect. Question: 1) What is the "C" after the 1400? 2) Did
the bios want to run the cpu bus at 200mhz ( in automatic setting )because of the SIS 730 chipset? 3) Is it ok to use the manual settings I used ( it runs fine ). ECS says this board/chipset can run the current and future AMD cpus, and goes on to say the SIS 730 chipset can do it.

The "C" signifies 266MHz DDR bus operation. "B" code would signify 200MHz DDR bus operation (100 or 133MHz actual bus speed, of course.)

And yes that SiS 730-based board you have can and will support future AMD processors.

I think Pabster answered this question very well.

A lot of BIOS' are set to run default at a slower FSB speed so that it will ensure that the PC is able to boot the first time so that you can get in and change the settings to what you want. Every time I take out my CPU and put it back in my BIOS sets the FSB back down to 66 MHz (it's a BX board) and I have to manually set it back up to 100 MHz.

Yes, the manual settings that you have stated you are using are fine.
