Function of 8-pin surface mount devices on back of Pentium 4 Package
Are the 8-pin surface mount devices on the back of the P4 decoupling
capacitors terminating resistors or jumpers that configure speed, core voltage levels and size of the internal caches after final factory testing and QA? Thanks |

You're getting closer. One of them is an I2C eprom (look at one of your dimms and you'll find essentially the same 8 pin part) and depending on the model P4 you are looking at the other(s) could be a temperature watchdog (ala DS1721 or LM75) and/or a FET switch... /daytripper |
