   • Notes
     • The K5 is Pentium-rated, and does not run at the speed given in its name. The K5 PR166 runs at 116MHz (66x1.75).
       
       
     • The K5 has unusual multiplers. When set to 1.5x or 2.0x, the chip actually runs at 1.5x. 2.5x is interpreted by the chip as 1.75x and a 3.0x setting on the motherboard becomes 2.0x in the chip.

   • Notes
     • Some boxed K6 chips come with a 3.4V CORE setting stamped on the chip. This is a mis-print. It should read 3.2V CORE.
       
       
     • Some of the K6 chips may have their speed etched into the upper right hand corner of the brown ceramic. Some don't.
       
       
     • The etched dots on the chip likely contain encoded info similar to that of the Intel Pentium-II chip (product info, UCC code).

     • The Plastic Pin Grid Array IC package has a metal heat slug as well as exposed pins on the top of the chip package. It is a 3mm tall, 49.5mm x 49.5mm black plastic chip carrier. It weighs about 18 grams and can with stand a maximum 100 pounds of force.
       
       
     • For the Plastic Pin Grid Array, Intel states:

       "For PPGA packages, electrically conductive surfaces should not touch any part of the processor except the heatslug. For instance, an electrically conductive heatsink should not contact the exposed pins, the external capacitors, or the metal on the sides of the package."

     • Additionally:

       "Intel cautions that components on the top and exposed metal on the side of the PPGA package can be shorted by any electrically conductive materials including heat sinks, thermal grease (if electrically conductive), and thermal grease foil carriers (if electrically conductive)."

     • Whether or not the heatsink grease is electrically conductive, it should not be applied to any surfaces other than the top of the heat slug (metal heat spreader).
       
       
     • Engineering samples will contain the letters 'ES' somewhere on the chip (often after the eight digit FPO#). They also have sSpec numbers that begin with a 'Q'.

      • The 333MHz Deschutes processors will have a '2.0V' mark written after the sSpec number (SLzzz). The original 2.8 volt Klamath will not have any voltage written on the package. Also, the part number for the Deschutes processor is 80523.
        
        
      • The Celeron chip does not have the SEC casing. The markings are written on the substrate.
        
        
      • The 2-D Matrix code looks like a matrix (checkerboard) of dots. It contains the Intel UCC numbers, product code, and FPO number.
        
        
      • Starting with the 366MHz Celeron, Intel is no longer using the iCOMP 2.0 performance rating system.
