Intel® Pentium® 4 Processor 520 supporting HT Technology (1M Cache, 2.80 GHz, 800 MHz FSB)
Intel 520 2.8GHz 1MB L2 processor
Note: To help meet the required processor thermal specifications, an internal ambient temperature at or below 38º C is required. It is strongly recommended to use a Thermally Advantaged Chassis (TAC) based on Chassis Air Guide 1.1 or equivalent.
With these new processors, Intel has introduced processor numbers as a means to identify the various features of the Pentium® 4 processor in the LGA775 package.
