maybe i got defect memory but i only running it @ 1333mhz because my platform is old(lga 775) and even @ 1333mhz heatspreader in ares more hot compare to gskill sniper when i touch them
i used 2x4gb gskill ares 1600mhz cl 9 about 3 month,and one of them is dead.and rma it with gskill sniper and until now (1&half year) no problem.i think heatspreader in ares not very good and more hot compare to sniper,even at same spec
