DDR 3 1600 has CL9 timings
There is one disturbing fact about DDR3. The timings will go bad but the speed of the memory will increase.
DDR3 800 memory will work at CAS latency 5 and 5-5-5 timings and as we all know DDR 2 can beat these settings as some good DDR 2 modules work at 3-4-4 timings and CAS Latency 3 (CL3). Well, that is not the worst latency you will see with DDR3. Some DDR3 800 modules will work at 6-6-6, CL6 timings but will probably end up cheaper.
DDR 3 1066 will start with CL7, 7-7-7 timings and DDR 2 at this speed works well at 5-5-5, CL 5 settings.
DDR3 1333 will work at CL8 with 8-8-8 settings while the fastest DDR 3 at 1600 will end up at 9-9-9, CL 9 settings. The good part is that all of these modules should work at 1.5 V.
We are sure that the companies such as OCZ and Corsair or similar ones will make these modules with even better settings and timings but these are the numbers to start with. CeBIT, the world's biggest IT tradeshow, will reveal a bunch of motherboards and DDR 3 memory modules.
Is the era of low-latency memory over for good?

7 Comments on DDR 3 1600 has CL9 timings
we just started to see CL3 ddr2 800 hit the market in the past few months
besides that the latency time is actually the same or less if you think about it
the speed doubles but the latency only goes from 5 to 9
so in the same 1 second span ddr3 is actually able to take more instruction than ddr2
The frequency vs timings for the new ram looks terrible though. High-end DDR2 can do more than 1200mhz these days, and at CL5 timings no less.
