Dell ® OptiPlex ® Gs and Gs+ Systems Documentation Update This document updates information contained in the Reference and Installation Guide for Dell OptiPlex Gs and Gs+ systems. New Microprocessor Options Dell now offers the Dell OptiPlex Gs and Gs+ systems with 166 or 200 megahertz (MHz) Intel® Pentium® microprocessors with MMX™ technology. The Pentium microprocessor with MMX technology is specifically designed to handle complex multimedia and communications software. This microprocessor includes new instructions and data types as well as a technique called Single Instruction, Multiple Data (SIMD) that allows the microprocessor to process multiple data elements in parallel, thereby improving overall system performance. The Pentium microprocessor with MMX technology has twice the internal cache memory (32 kilobytes [KB]) as the standard Pentium microprocessor. CAUTION: The Pentium microprocessor with MMX technology has different voltage requirements than other Pentium microprocessors. Do not install a Pentium microprocessor with MMX technology in a Dell OptiPlex computer system other than the OptiPlex GXi and OptiPlex Gs/Gs+ systems. These new Dell OptiPlex Gs and Gs+ systems have the same features as the previous Dell OptiPlex Gs and Gs+ systems except for the Pentium microprocessors with MMX technology. The following systems are available: • The Dell OptiPlex Gs and Gs+ 166 system uses a Pentium microprocessor with MMX technology that has an internal speed of 166 MHz and an external speed of 66 MHz. • The Dell OptiPlex Gs and Gs+ 200 system uses a Pentium microprocessor with MMX technology that has an internal speed of 200 MHz and an external speed of 66 MHz. The microprocessor-speed jumper settings on the system board are the same for the Pentium microprocessors with MMX technology as for the standard Pentium microprocessors. Current application programs not designed specifically for MMX technology should have a small improvement in performance when run on Dell OptiPlex Gs and Gs+ systems with a Pentium microprocessor with MMX technology. Software written specifically to take advantage of MMX technology (usually labeled "Designed for Intel MMX") shows greater performance improvement, depending on the type of application program. © 1996 Dell Computer Corporation.
