FSB

[Mr. Yort]

Can you use a 266 fdb cpu on a 200 fsb motherboard?
I Have a thunderbird 800 and the asus a7v motherbord vision tect gts, 512 133 ram, SBlive was think of upping the cpu but a 266 or 200 fsb?

Welcome to the Forum

The 266 mhz refers to the internal speed of the Tbird (2 x FSB or 2 x 133 mhz) while the Duron has a 200 mhz internal speed (2 x FSB or 2 x 100 mhz).. So providing your motherboard supports a 133 mhz FSB you can run a 266 CPU and use it performance, fitting it to a lower bus speed will inturn reduce the CPU's speed.

You may also obtain more suitable answers if you let people know what system specification you have, as someone may have experiences of trying your question.

short answer... yes, but the cpu will run at 200fsb, not 266.

If the motherboard is a 200fsb board (100mhz x2) and your T-bird is a 266 chip, you have to run your board at 200fsb... hence the chip will also run at 200mhz. If you tried to run your board at 266fsb, you would be overclocking by 33% (since its only designed to be a 200fsb board)... a pretty hefty overclock.

To answer your question, you would have to start running the board at the default setting (200fsb), and if you wanted to overclock, move the fsb up from there.

I didn't see anything about your chip/case cooling system, which is essential before attempting to overclock.

I was just wondering what cpu to buy 200 or 266 if I buy a faster one. Running at the default setting would I have problems with a 1200/266 set to 1200/200 this would allow me more room to overclock but if the cpu would prefoam worse than the 1200/200 at that fsb setting I would buy the 200 fsb version
