i am using Corsair dominator C4D, i use it with e6300 @ 2800 mhz, i use this ram usually at its stock speed 800 mhz, some times i overclock it to 1000 mhz with raising the voltage to 2.3~2.4v but i don't get the system stable, any overclocking beyond 1000 mhz caused windows not to boot,
even i boot the system @1200 mhz ram freq. but windows could not be booted,hanks
i lose the timing to max. values but the result is same,

any suggestions,

thanks,..
