Memory Voltage in Overclocking

It's rated specs are 1600, my mojo the asus m4a79xtd evo knocked it back to 1333 its a known issue with the board so I put it back to 1600 but I'm still at 2T and unable to change... thanks for all the responses BTW

****HERE'S THE ANSWER****

ok guys i figured it out in case anyone was wondering; it IS because of the motherboards dual channel. i am running 4 2gb sticks.. on the boards 4 ports 2 are blue 2 are grey and they are separate channels so all 4 sticks cant run at 1T but they can at 2T.. i found this out because my friend has the same board and RAM and processor, but he can get 1T, but he's using 2 4gb sticks in the same channel.

Hello everyone, im trying to overclock my gear and i need a little help... Right now im working on the memory, im just trying to get a little bit extra without damaging anything...

my timings right now are 9 9 9 24 and its 2T... im trying to get it set to 1T for now but when i change it in the bios and try to start up it says overclocking failed and i have to put it back to 2T to get it to start up... i think this may be because my voltage is set at 1.50.... in the bios it says the min is 1.50v and max 2.50v... i would like to know what i should set it as to get it down to 1T....

im also going to up the Processor today, but first im going to go buy a new heat sink to make sure i dont damage anything, going to get a Zalmans, anyone have any recommendations for some overclock settings for the CPU as well? its at 3.2 now, im only lookin to moderately boost things...

any recommendations for Overclocking settings?

For CPU , If you have succesfully installed your aftermarket heatsink, watch the temps differences first.After that you can go up to 4GHz with stock CPU voltages ( 1.38 v)without changing bus speed.
