The new tri-channel configuration for the Intel Core i7 CPU & X58-Express Platform certainly has its benefits, but some of the old traditions are lost in the new standard. Because of the high penalty for round trip cycles, latency offers a bigger performance incentive than clock speed. Sure, it's nice to reach 2400MHz or faster with a DDR3 kit, but if it takes one or two extra strobe cycles to generate that speed the benefits are lost. This essentially divides triple-channel memory kits into the following preference order:

1.
Low Latency (CL6 or lower) + High Speed (1600MHz or faster) = Most Preferred
2.
Low Latency (CL6) + Standard Speed (1333MHz) = More Preferred
3.
Standard Latency (CL7) + High Speed (1600MHz or faster) = Preferred
4.
Standard Latency (CL7) + Normal Speed (1333MHz) = Acceptable
5.
High Latency (CL8 ) + High Speed (1600MHz or faster) = Less Preferred
6.
High Latency (CL8 or higher) + Low Speed (1066MHz or slower) = Least Preferred

Kao što vidite postavke letencija memorije zbilja igraju ulogu kod performansi u igrama.

Poželjnije je imati memoriju sa letencijom CL6 NA 1333MHz nego memoriju sa letencijama CL8 na 1600MHz i više.
