can someone explain the importance of clk and speeds of ddr ram

Brutherb · Mar 13, 2014

I just purchased a ASUS Sabertooth 990FX R2.0 and an FX-8150, samsung evo 500gb ssd, i need to pick out memmory but not sure how much difference, 1600-2300 makes or clk 9,10,12 etc, i don't really do anything that requires tons of performance but want to build a decent machine.

First things first, you look at your CPU and it's capabilities as far as frequency of DRAM the 8150 is 'rated' up to 1866 at 1 stick per channel, so 2 sticks (and not all 8150s can handle the 1866 freq. With AMD it's good to go for the max freq a CPU can handle as they have weak (compared to Intel) MCs (memory controllers), so for a 8150 I'd go 1866, particularly since you can always downclock and tighten timings....next to the CLK more commonly called CL (CAS latency) or just CAS, briefly it tells you how many clock cycles it takes for the DRAM to complete an action, so lower is better, at 1866 CL9 is a good one to run at....as mentioned above, if your particular CPU can't handle 1866/9 can try 1866/10 settings or drop the sticks to 1600/8 which is near same as 1866/9...the higher the frequency, the more bandwith which helps greatly in multi-tasking, memory centric apps (imaging, video, CAD, etc) or when working with large data sets...hope this helps
