hi i have this motherboard: http://www.newegg.com/Product/Produc...pk=z77a%20gd65 and this ram ( 2 sticks, total of 8 gb ) http://www.newegg.com/Product/Produc...82E16820231445 and i want to add two more 8 gb crucial sticks for a total of 24gb ( for use with Vegas Pro 11 editing HD videos ). now crucial says this one is compatible: http://www.crucial.com/store/mpartsp...DC29C3A5CA7304 but i want to do a light overclock on my 3770K ( to about 4.2 ghz ) and i never overclocked before so i don't know if getting this model ram would interfere with my ability to overclock ? i can't get ram with heat spreaders because my noctua NH-U9B cooler is blocking the ram slot closest to CPU - or rather it will only allow a ram stick in there that is without a heatsink. i hope my question is clear ? if not please let me know.
