There were two variations of Pentium III Tualatin microprocessors. Desktop version of Pentium III Tualatin CPUs had 256 KB L2 cache. Server-class processors had 512 KB L2 cache and were branded as "Pentium III-S". You can see on the picture that the processor is marked as Pentium III-S. The difference between desktop and server Tualatin microprocessors was not only in L2 cache size. Desktop processors didn't support dual-processing, and only Pentium III-S CPUs could work in dual-processor systems.
