Need help understanding RAM and my CPU

CPU will live shorter life if they are constantly at high temps, it can go all the way to 100C before computer shuts itself down to prevent any damage. You should really consider getting better cooler, stock coolers are absolute shit.

actually I didn't mean overclocking the CPU but overclocking the RAM itself. There are options to do so on many motherboards in the market.

Why would you want to do this "damage" to your system just for a few more clocks on RAM and CPU which you won't even feel in the actual performance?

Sorry english is not my main language.

A Processor final speed is based in two main factors Base Clock (from now on BCLK) and the multiplier, for an example in the i7-980 the BCLK is 133MHz and the default multiplier is 21, hence the 2.8GHz speed (133*21 = 2793MHz), the Turbo Boost from these Intel processors works by increasing the multiplier from 21 to 26 based on system load and core usage.

In this generation of processors the BCLK are also responsible for RAM speed normally with a multiplier equals 10, since the BCLK is 133MHz the speedy of the memory is 1333MHz.

Let's say you bought a memory stick rated 1600, but if you put it in your system it will run only at 1333! How to fix that just up the BCLK to 160, but by doing that your processor will go from 2.8 to 3.4GHz, since you don't want the processor to heat up in the stock cooler you may reduce the multiplier to 18 reducing the final speed back to 2.88GHz close enough to stock speed.

Better? Intel specs page only tell you the stock speeds, not the max speeds, with the right hardware you can make your processor to get 4GHz and memory up to 2133
