Hello guys 

There are so many modules with diferent frequencis i wathced a vido on youtube that in some games and aplications fater mhz ram is better but i dunoo with to take 2666mhz or 3000mhz if you look at diferenz stores they are priced 5 euros or more the diference.

If they are priced within an acceptable tolerance for your budget, then get the fastest MHZ possible with the Lowest CL available.

in the reality and real world performance you'll not notice any difference what so ever between lower and higher frequency, as long as it is ddr4 you're good to go, also do pay attention if your motherboard supports higher clock for the ram, some will be locked on lower frequencies and even if some are compatible they might be through OC which will  require you to set it up in the bios.

Ram speed helps when there is a CPU bottleneck. (Digitalfoundry did this test several times). 

If your cpu is performing a particular task, that takes it to 100% usage, increasing ram speed will increase performance. The maximum growth possible (theoretically speaking) would be a lineal growth. But it also increases the latency and the strain put to the IMC in the CPU so it may decrease your overclocking capabilities and system stability (because it can't hold the set overclock parameters). High speed RAM may also come with an increased operational Voltage, which depending on your CPU it may not like it at all. It happened before, so research is highly recommended on this matter. (see CPU and motherboard compatibility list before cashing in). 

 

Now with theory on the table i tell you this: You won't notice any significant difference unless your CPU is old and/or weak for the kind of games you play, and in this case, don't waste money in pricey ram. Save it and but a new rig/better CPU. 

 

cheers!
