Function of 8-pin surface mount devices on back of Pentium 4 Package

Post by Gerhard v » Fri, 27 Jun 2003 18:18:07


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...
