why single channel?

put at different slot
1st and 3rd

need to understand what is EIST: HERE
when u enable EIST etc the CPU will downclock during idle.
you will get back the OC speed during load.

my room is very hot actually. but i guess i can leave with lower cpu speed for now as long as its not hard, i downclock it back to 3.0ghz from 3.6ghz, used default on everything but vcore, which is at 1.18xx volt (forgot the exact number) , and running on 1066 ram speed. I tried on 3.4, it works, but its not stable at all. i had to lower my ram to 800 to make it work. I need to know what i need to adjust in order to get 1333 or 1600 ram speed respectively (or at least make mine run at 3.6ghz without sacrificing my ram to be downclocked at 800mhz. Yes i know this sound like a noob-ish question, but I'm really new in oc field, but i would love to see some positive numbers result, been resetting my cmos like nobodies business for few hours just to fiddle the correct setting. Thanks for the reply in advance
