Command rate?

post #1 of 6
Thread Starter 
I have noticed in many ram threads that they talk about command rate. What is this? Do all chipsets have this or just certain ones? I know that there is no way to change this on my mb and in my cpu-z i dont get any reading on it either....

Here is some good reading that explains memory and timings.

What about Command Rate?

Command Rate is sometimes referred to as DRC (DRAM command rate). This is the setting that selects the speed of your RAM signal controller. If it is set to 1T, then the controller will run in synchronization with your bus speed. Higher settings will result in slower overall RAM speed, which translates to less bandwith and yes (you guessed it) more headshots for you. Most decent RAM modules will run at 1T, but some have to be set to 2T. The moral of the story here is don’t buy value select RAM!

The 680i chipset can modify the command rate and the 965 Intel and P35 don't have the option to in the BIOS as far as I know. Some Intel chipset boards might have it but I don't know wich one if there are.

P35 does have the option to modify it with some of the new bios's.

basically 1T is really really fast. From what I have heard 1T at 900 mhz low timings is as fast as 2T 1100 mhz.
