Even MHz fclock is stronger than MHz fclock. Oct 4, 52 18, What board do you have? Oct 8, 5, 1, 33, Only the 3rd-gen Ryzens can typically handle that. The difference between and will generally be quite minor. Adding RAM from other kits does have the potentially to cause stability issues though. So selling the existing kit and replacing it with a 2x16GB kit of DDR might be a reasonable option. If you are just using this system for gaming or most other tasks though, you probably don't actually need 32GB at this time.
It could be useful for the future, but for now, 16GB is plenty for gaming and most other common desktop tasks, and you are unlikely to see much performance benefit from adding more.
As for the reason CAS latency tends to appear higher with faster RAM, it's because at higher speeds, each clock cycle is shorter, so it takes more of those clock cycles to equal a given length of time. That number is referring to the number of cycles, not an absolute measurement of time.
You'll notice that the CL number divided into the frequency equals the same result for all of them, as they are all referring to the same length of time. They will all take the same amount of time to begin accessing a location in memory, though the faster memory can then transfer data faster after that point. Zerk Titan Ambassador.

Mar 14, 20 18, I'm not sure if you'll read this post after having already picked "Best Solution", but it looks like from reading your original post that you are considering adding a second set of 16 GB Dram to get to 32GB. That approach may not work. Memory sticks are fickle. Only 4 stick kits that have been tested together by the manufacturer are guaranteed to work.
If you add a second set of memory to your existing set it may or may not work. Just luck of the draw. You must log in or register to reply here. Is there a way to tell? Post thread. News Comments. What's new. New posts. Log in.

Since I don't really know how much difference RAM speed makes, I decided to ask here, as if it's not that much I would definitely prefer the better IO, but as far as I know it could be cause a huge difference.

For Ryzen, you want the fastest you can get within reason Adding more memory to your PC is one of the best and easiest ways to improve system performance. DDR4 memory is the latest generation of memory for computing applications and offers many benefits over previous generations of memory including lower latencies, higher speeds, and more. One thing to keep in mind is that memory needs to be the same type - memory modules are not forward or backward compatible in terms of generation types so DDR3 will not work in DDR2 or DDR4.
Memory is designed to be backward compatible within its generation, so generally speaking, you can safely add faster memory to a computer that was designed to run slower memory. However, your system will operate at the speed of the slowest memory module installed.
Rather than give memory modules catchy names, the industry refers to modules by their specifications. But if you don't know a lot about memory, the numbers can be confusing. Here's a short summary of the most popular types of memory and what the numbers refer to.
