Tbird 1Ghz default at 750Mhz?

[nyankos]

Hello,

First time on this board along with being a new AMD owner. I figured this would be a good place to get some friendly support from all you AMD gurus. Anyway, what happened is that I bought a OEM chip from newegg.com (1Ghz Tbird) however, it is running default at 750Mhz (100 * 7.5) I checked out the CPU and the markings identify itself as being the right chip, soooo it must be a motherboard problem. I have an Epox 8KTA3 that has the BIOS set at its defualt settings. Thank you for any replies in advance.

I'm pretty sure you can get 7.5x133 = 1ghz by changing the fsb jumper on the mobo to get the higher fsb then change the fsb in the bios and you will have your 1ghz cpu. Or you can change the dips to 10 and have it 10x100=1ghz

Your problem is not that 750 is its default speed..the problem is that your mobo thinks it is the default speed. Change the 100 to 133 and your cpu will be running at its actual default speed. Using jumpers or the BIOS...

Yepper, my moterboard was at 100 instead of 133. It was a jumper setting as you all mentioned.

Still kind of confused why I am playing with FSB of 100/133. My old celeron ran at 66, and from my understanding PIII run at 100/133, but the AMD is supposed to be at 200/266?

The speed at which K7 & newer commincate with the chipset is DDR, doubling the clockspeed. The memories run at SDR, unless DDR memories, of course.

The AMD chips run at 200/266 internal to the CPU, externally it is 100/133.
