AMD Tbird 1GHz = 750MHz???????

[pm4345]

I am building a 1 Ghz system and the processor constanty comes up as a 750Mhz. I tried it initially on a ECS motherboard and figured since ECS make junk, will try it on another board. Ordered a Gigabyte 7IXE-4 and that too finds it as a 750Mhz. I took the fan off and the processor says A1000 on it.

Were am I going wrong? Shouldn't both motherboards autodetect the processor speed?

Thanks..?>?./1.1/. <IMG SRC="smilies/frown.gif" border="0">

I work with ECS boards all the time. I know on some boards there are 2 jumpers on the right side (looking at it with the keyboard connector to the left) that control FSB. These boards come default at 100 FSB.

Other boards detect the FSB, but you must set the multiplyer in the bios.

BTW, did you even bother to look in the manual?

Okay like noted up above, did you check the manual. Also, where did you get this cpu from? it could be shady! Also, what methods of clocking the cpu are you using??? What bus speed are you using. Or you going by fsb or what?

I am really confused. I built a SLOT A Athlon 800 and the motherboard found the processor at the correct speed. I have tried both kinds (PC100 and 133) memory in the board. I looked and looked and on the ECS I couldn't find any jumpers.....

On the gigabyte, there are jumpers that allows me to set the grequency at 90mhz 100mhz etc. I went all the way upto 115mhz which brought my processor speed to 863mhz.

Should I try something else? In the BIOS what should I be looking for?

Thanks for your help. <IMG SRC="smilies/smile.gif" border="0"> <IMG SRC="smilies/frown.gif" border="0">

I have a amd 1.13 and if the FSB is not set to 133mhz it comes up as a 850. My asus board has this setting in the cmos.

You need to use a motherboard that supports a 133 mhz or higher front side bus. The gigabyte board you mentioned only supports up to 115 mhz.

863 mhz / 115 mhz fsb = a 7.5 multiplier (which i believe is the highest you can use on the board). You need something that can do 133 x 7.5 to equal 1000mhz (1 gig).
