Trust me, my rig isn't slow...when it comes to DRAM, most opinions are based on what people have read others say and there's two primary groups Group 1 says the you want the lowest CL you can get....period. Group 2 will say you want the highest freq you can get....period....sad part is neither really understand DRAM, the best DRAM you can get is the best combination of high freq and low CL.....the combos I listed above on the Tridents are considered performance sets - the 1600/7 1866/8 2133/9 etc - more staid or entry level sticks are like 1600/9 1866/9-10 2133/10-11 etc.....if you look at say 1600/9 vs 2400/10 then if you follow group 1's theory then the 1600/9 is clearly the better of the two since it has the lower...
