I have 4 Gb of this RAM but cannot get them to run at 1600 mhz. the motherboard has them set originally at 1333 with 9-9-9-20 as the timings and at 1.5 volts. I went into the BIOS and changed the speed to 1600, the timings to 8-8-8-24 and the voltage to 1.65, but I get random BSODs. I have tested the ram in memtest, and everything was fine with it. does anyone know of something else i could try?
