I want to get back into retro PC gaming and I got my hands on an old Optiplex GXi with the following specs:
Dell OptiPlex GXi (small form factor desktop model)
Intel Pentium 166MHz, 256KB L2 cache memory
32MB EDO RAM
On Board Video: S3 Trio64V
On Board Audio: Crystal CS4236-KQ Chipset
I looked a bit in the user guide here: ftp://ftp.dell.com/Manuals/all-products/esupr … Guide_en-us.pdf

New Microprocessor Options: OptiPlex GXi
Dell offers the OptiPlex GXi system with 166-, 200-, or 233-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 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
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 a Dell
OptiPlex GXi system that has 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.
Does that mean that I can safely upgrade the CPU to a Pentium 233MHz MMX?
