I 'overclocked' the RAM to 1000mHz, even though that's its rated speed, and it appears to be running stable now...but the voltage seems to be set as a range of 1.8 to [2.8v (but is only drawing 1.9 at the moment). Also, Nvidia nTune software is registering my memory voltage with a 'red' warning symbol, saying that it's overstressed at 1.9v. Not sure if this is accurate, as it said that about my old 667mHz stock RAM, but I don't want to damage my 'new' system/RAM. If you can't tell, my tech experience isn't too low, but definitely not high enough for my tastes, lol.
