 |
|
| Does anyone know how to determine the speed rating of NexGen CPUs which do not have their speed, or P-rating, printed on the surface of the chip? I see chips on chipdb which don't have the speed marking, yet the up-loader input a speed rating. Thanks! |

| The unmarked Nx586s that I have seen were all used as P90 (telling from the jumper settings on the motherboard). |

Mine unmarked (and without stamp on back) came with mobo switched also to P90, but not all of them were p90:

| Ah, yes. These are with the bigger heat-spreader. I had only thought about those with the small heat spreader. |
