Jeff, Simple arithmetic tells us that 12 ns = 83.3 MHz. A reputable manufacturer would never put 12 ns SDRAM in a 100MHz system - even if it works MOST of the time. Just like they don't overclock the CPUs. Larrys question was on 100mhz memory not 83mhz. I just threw that in to make a point. Also, Overclocking Intel chips has nothing to do reputable manufacturer's, it has to do with understanding Intel products and their very high yields. They actually make chips so well now that they are actually all at the high end of the performance scale. They just stamp them with different frequencies. Third, 60ns and 70ns memory is installed in PC's with 66MHZ bus rates. Did you calculate the megahertz for the chips. You might be surprised at the results. This is also simple arithmetic.<g> DavidG

Jeff, A reputable manufacturer would never put 12 ns SDRAM in a 100MHz system - even if it works MOST of the time. Just like they don't overclock the CPUs. Just an afterthought. Reputable manufacturers do indirectly overclock cpus. You should delve into how Cyrix and AMD arrive at their 686 and K6 speeds. They are pushed to the limit, unlike INTEL, and they stamp the frequency at the high end. As an example, Cyrix chips run so hot for their socket 7 chips that they had to design a special heat sink and fan for cooling compared to the standard heat sink and fan for INTEL. ...now wouldn't you call Cyrix a reputable dealer and yet most would agree they are overclocking compared to INTEL. Overclocking is a relative term compared to different manufacturers and certainly subjective. DavidG

Jeff, Isn't Micron working on 133MHz SDRAM? From MU site these are the 3 products of SDRAM. I believe the 125mhz MU is still working on and will be availble during '98 in volume. Speed Grades Micron provides 83 MHz, 100 MHz and 125 MHz speed grades, marked as -12, -10 and -8x respectively, with the high-volume output in the 100 MHz, or -10 speed grade. Both -10 and -12 conform to the de facto industry-standard PC requirement for a tAC = 9ns at 66 MHz, CAS latency = 2. Micron's -10 and -8x meet the PC66 amd PC100 specifications, including support for concurrent AUTO PRECHARGE.
