I've recently gone from a DDR2/LGA775 setup to a DDR3/LGA1155 setup. With DDR3, the timing numbers are quite a bit different than I am used to with DDR2.
My question is: Which is going to be more important for overall system performance, timings or command rate? I can get a command rate of 1T with timings of 9-9-9-24, or I can get timings of 7-7-7-20, but bump my command rate to 2T. I know with DDR1 and DDR2, having a 1T command rate was considered very good if you could get it without completely hosing your timings.
I have a 1600mhz rated RAM, but I am not running it at at that frequency. I am currently running it at the stock 1066mhz, with no real plans to change it, as I do a lot more random access on my computer than large sequential data sets. Unless I am misunderstanding DDR3 completely, I am going to get more out of decent timings and a good command rate than I am a high RAM frequency.
So, 1T command rate or tighter timings?
Some extra system info, in case it helps:
Core i5-2500k MSI P67A-G43 (B3) 8GB (2x4GB) Corsair Dominator DDR3 Windows 7 Pro 64-bit
My system is used mostly for gaming and development tasks.
