Good cpu
I am using this cpu with an ASUS P4U800-X mainboard. The mobo is equipped with ULI chipset. As you might guess, mobo is not the best for overclocking.i easily overclocked this cpu to 3.22ghz without any problems, system running stable for months. 15x215 = 3225MHZ !
Really a great cpu cause i don't use my AthlonXP Barton 3000+ anymore. Btw cpu temp is about 55 idle, 65 load. Not bad :)
Change Fan & Heat Sink
I change to a well known 3rd party HS & Fan and overclocked the cpu to 3.2Ghz. My computer is STABLE AS A ROCK and Runs Great! If you want to play around with overclocking processors this is the one. Also remember to get a good Motherboard it will make the world of differance. I also recommend a cooling HS & fan for the North bridge and RAM. Wish me luck, I'm about to install a water cooled system for the cpu and hope to push it to 3.4Ghz or better.
Re Heat Build up
I also have one of these CPUs, with reported temperatures sometimes reaching 100degC.
This CPU is supposed to have a "Thermal Monitor Feature" that can reduce processor temperature by controlling the duty cycle of the processor clocks. Further, if the temperature reaches 135 degC, the CPU is supposed to halt.
There are many reports elsewhere about the higher speed Prescott CPUs generally suffering from excess heating problems.
Heat Build up
I had this processor and coupled with DDR 400 memory it had excellent performance. I was using the Intel Heat Sink and Fan. The combination is not sufficient. My processor was running at 112 degrees and before I could change the fan the CPU gave out. I will be purchasing another SL79L (3.0E GHz) and use an improved/better 3rd party heat sink and fan and hopefully I can get the temperature down to manageable levels.
