drw 2 ram at 666mhz working at 332mhz in cpuz
CPU-Z shows the actual clock time. The RAM is advertised as a marketing speed that's twice this, because it moves two data units per clock cycle.
I believe the DDR4 model offers 4200 MHz performance, meaning real clocks are around 2100 MHz with potential for even higher speeds. Some listings advertise 4800 MHz, which translates to an actual clock speed of 2400 MHz.
Recently posted by a user. 5GHz RAM available. Link to article about Corsair's high-speed DDR4 kit.
It seems Infinity Fabric increases its clock speed to 2:1 when it hits 37xx MHz. Beyond that, you might get higher performance but at a cost that doesn’t justify the gain.
