Sorry for hijacking and lame question. With 4x multiplier and FSB 25 MHz it have great OC potential ? Reaching 33 MHz shouldn't be hard to get ? _________________ Visit ABC CPU - Virtual CPU Museum. |

Cx5x86-100 rarely works at 133MHz. 120MHz may be possible with a voltage increase. Although 4x30MHz doesn't make much sense compared to 3x40MHz. _________________ My Active Sales |

| I haven't come across any reports of the 100/4x chip running reliable at 133MHz, but there re several reports indicating that it does not run at 133MHz |

| My 100GP-4X won't do stable 133. I have a few standard 100 and 120GP and some even run stable at 2x66 in DOS and games. But won't load Windows 95 in any case. 2x60 does work fine on the other hand with reg optimizations. |

| For me, only the IBM QFP 5x86c chips will run reliably at 133 MHz, that is, aside from the Cyrix 5x86-133/4x. |
