underclocked 266fsb athlon on kt7-raid?

[dhollcroft]

wondering if i can get the most of my mobo by running a 266fsb athlon on it. not sure if it will run underclocked if the chipset is unable to run at full speed. any ideas?

I dont think you will be able to run at 266 Mhz FSB on ur mobo. Most KT133 based mobos will go up to 112 Mhz only, some rare mobos will go up to 124 Mhz. Unlock ur cpu to use the multiplier, and try to run it on the highest FSB you can run it.

Good luck!

I have an Asus A7pro KT133 motherboard (with only 100MHz official fsb support) and 1.33GHz Tbird with 266MHz FSB (10.0 x 133MHz). As a default, the CPU ran at 1GHz (10.0 x 100MHz). As just about all 1.2GHz+ Tbirds, the CPU came unlocked, and I managed to raise the multiplier to 11x chip (1->1.1GHz). Currently I'm limited by my cooling solution (a crappy Celeron/P3 fan, 70C stress temp) so I won't clock it any higher and closer to the rated speed just yet.

So to sum it up, a 266MHz FSB CPU will run just fine on a 100MHz FSB, KT133 chipset motherboard. If the chip is unlocked and the motherboard supports multiplier manipulation, you'll most likely be able to raise the clockspeed up to a point where the CPU is not even underclocked.
