Just bought a StrikkerII extreme and a qx9650 . Do you think I should keep the 2 packs of Patriot Extreme Performance  (2 x 2GB)  DDR3 SDRAM DDR3 1600 (PC3 12800) ( PDC34G1600LLK ) or get something else. If I return it i have a $780 credit from newegg to get 8 gigs of something else.  
 
Only reason I'm thinking of returning it is b/c I read a few bad reviews about it not getting 1600 mhz 7-7-7-20, 1.9V as advertised.

I've been using this for that last two months without any hiccups --> Patriot Viper Extreme Performance PC3-12800 DDR3-1600 CL 7-7-7-18

i think they are differnt slicks.  i didnt get the viper cause it was a bit more
