DDR3 1600 with CL9 timing?

Generational change is approaching, information about DDR3 memories is leaking.

It is probably not new to anyone that the age of low-latency memories has expired with DDR2, but how these values ​​increase with the advent of DDR3 has not been known so far.

The current news sheds some light on this. For the slowest DDR3-800 modules, we can talk about 5-5-5 timing and CL5 delay, as opposed to similar clocked DDR2 modules, which typically have 3-4-4 and CL3. In addition, it is possible that a DDR800 memory with lower specifications (6-6-6 and CL6), but also operating at 3 MHz, will be introduced later.

The DDR3-1066 will have a timing of 7-7-7 and a delay feature of CL7, while for a DDR2 memory with the same speed, we can talk about 5-5-5 and CL5 settings. The 1333 MHz DDR3 modules have CL8 and 8-8-8, while the 1600 MHz peak model has CL9 and 9-9-9 delay and timing value.

In any case, we can be sure that more reputable memory manufacturers like Corsair or OCZ will make a version of DDR1,5 memories with 3 volt operating voltage with even more favorable specifications anyway.

In any case, the news is that these values ​​should not be converted one by one between DDR2 and DDR3 memories, but it is certain that next-generation memories operating at the same speed in theory generally perform worse than members of the previous generation.
