    Description

    Intel Pentium III 1000 MHz Slot 1 desktop CPU, SL4BS, Coppermine, 133 MHz FSB, 1.7V
    Here is a scarce 21-year old CPU from Intel running at 1.0 GHz.  This is one of the last Coppermine Pentium III processors, and one of the few Coppermines made for Slot 1. Intel's S-Spec number is SL4BS.  By the time of its release in 2000, socket 370 CPUs and motherboards were common. This one used the same Slot 1 as the original Pentium II and Pentium III.  However, it requires PC133 SDRAM, an appropriate BIOS and chipset to run at the full 1000 MHz.  If the front side bus is set to only 100 MHz this will run as a 750 MHz CPU.
    If you are not sure whether this will work in your system, please ask me before your purchase.  I would rather tell you "no" than have both of us waste time with a return for compatibility reasons.
    You will receive the exact CPU pictured here.  I include a Compaq aluminum heatsink as pictured.
    I welcome questions from interested buyers and offer a 30 day return privilege.
