Is the 2133mhz or 1866mhz much faster than the 1600mhz ram?

or is the difference in performance/efficiency of the cpu very minimal?

And should i consider CL11 over CL9?

More about : 2133mhz 1866mhz faster 1600mhz ram

Best solution

Memory is a very fascinating thing. People will spend hundreds and hundreds of dollars more for higher frequency ram, when in reality they run just about every task the same way. There are very few things that will actually be able to take advantage of higher frequency RAM. To explain; what you should consider when buying RAM is the frequency, the Cas Latency (CL), as well as the price.

First, let's cover frequency. This is the speed of the ram measured in MHz, and despite common belief, even if you spend hundreds of dollars more on a higher frequency RAM, without the proper Cas Latency backing it, it could all be a waste of money.

Cas latency is the amount of cycles the RAM has to undergo before it is able to complete the task.

Let's take these two definitions and apply them to buying ram. You see a RAM stick that is running on DDR3 1600, with CL 9. To test how fast that will run through a task, you do 9/1600 and receive 0.0056. This is the amount of time (in seconds) it will take to complete a task. Now, you stumble upon DDR3 2400, CL 11. You would do 11/2400 and receive 0.0045 seconds. If you want to spend another hundred or two for 0.001 seconds of speed, then be my guest. It's just not a smart choice if you are operating on a budget.

I hope this explanation helped. If you have any further questions feel free to message me.

The 1866 is not that much more than 1600, not a bad choice, the 2133 does not buy you the performance it cost so I would pass on it. 1600 or 1866 would be a smart buy, CL9 or CL8 is what you want to have, hope this helps..

You want to look for the highest freq with the lowest CL at the best price - it also depends on what you, high freq won't be of much of an advantage if all you do is game or single task, high freq comes into play when multi-tasking and using memory centric apps like those for imaging, video work, CAD, GIS, VMs, et al or apps using large data sets

Another thing to consider is the amount of its transfer rate.
A friend told me he has one 8GB 2400 DDR3 that is faster than my 2 8GB DDR3 2133.
So he thinks DDR3-19200 9-9-9-24 is faster than 2 DDR3-17000 11-11-11-27.
So as I see it I can move 2x17000 over his 19200.
CL timing or not.

I know this is old so i hope you are still using the site. i Just purchased a R( 290 PCS+ and decided to up my RAM aswell to G SKILL sniper CAS 10 2133 from my CAS 10 1600. Based on the above statement is the math only by the first timing? I read that faster ram can help high end GPUs perform better and that i could get as much as a 10% increase gong from my GSKILL ripjaws i stated before to the new SNIPER series below.
I wanna thank you in advance for your help!!!

Here is what i am recieveing in a few days:
