I would rather run my 333/66 as 300/100 but I can not. Technically running 333 MHz as 350 MHz should not be considered overclocking. It is not because the difference between 333 and 350 is small but because the CPUs are exactly the same internally. What different is the packaging. 350 MHz CPU supplies a different (from 300 MHz) voltage between two certain pins of the cartridge. This is supposedly to inform the bx or gx chipset on whether a 100 MHz bus compliant CPU is installed. But really it is in order to check whether you were willing to pay 50-70% more for the same CPU. And since most of the motherboard manufactures allow you to choose the bus speed manually between 66 MHz and 100 MHz, why not go for it? Again, this is not about overclocking. For example, 120MHz Pentiums and 133 MHz Pentiums were really different in quality and there were problems with remarked chips. I happened to see a remarked 120MHz Pentium running Linux at 133 MHz. The box became unstable during the summer and the CPU had to be replaced (this is how the whole issue came about). In this situation, however, we are talking about the same CPUs. 333MHz are sold for 66MHz boards and 350MHz are sold for 100MHz boards. This is not a unique situation with Intel -- remember those Cyrix chips that were sold as certified to run at several slightly different speeds depending on the board clock (65, 75 or 83 MHz). In this case, however, Intel has decided to cache on the deal. And hence, a special trick with the voltage to inform the chipset whether you have paid the price, and following the decision of the motherboard manufactures to let people manually choose the bus speed, a locked multiplier. And no, I do not believe in overclocking from 350 MHz to 400 MHz. 350 MHz and 400 MHz have the same CPU core but different cache. Overclocking a 350 MHz to 400 MHz will almost certainly cause problems, even if they are subtle. I need to do a lot of number crunching and I like the two runs of one program to produce the same results. Also, being a gx based chipset, my board supports only 66 and 100 MHz bus speed (I am not aware of gx boards which can do more but maybe there are). ---------------------------------- Constantine Gavrilov Unix System Administration MIS, Indigo Ltd.
