News: MOD AthlonXP per 400FSB

[Staff]

<br>
Sembra che alcune cpu AMD AthlonXP con core di default a 333mhz di fsb, abbiano alcuni problemi a rimanere stabili in overclock a 400mhz di fsb sulle schede madri basate su chipset Nvidia Nforce2.<br>
Sudhian ha trovato un <a href="http://www.sudhian.com/docs.cfm/id/307.sud">rimedio</a> al problema, che consisterebbe nel tagliare uno di interrompere uno dei collegamenti dei bridge L12

The problem, apparently, is that the nForce2 (and possibly the KT400 as well) destabilizes when the front-side bus is overclocked using a 333 MHz FSB CPU. The solution (which we've tested) is to cut one of the L12 bridges on the CPU—the exact one is pictured below. Cutting this particular bridge forces a motherboard to recognize a CPU as a 266 MHz part, rather than a 333. Because the CPU's multiplier is still set to 12.5 (and full adjustments are available) it means default settings will drop the chip to AMD 2000+ speed, but the CPU can easily be returned to a default multiplier and 166 MHz bus.
