Does CAS latency matter for gaming?

Yes, they do. However, CAS Latency is still the most commonly used metric to compare memory latency because it more directly affects (immediately) how fast your RAM module responds to a request.

How does CAS latency affect gaming?

CAS latency is an accurate indicator of real world latency performance. As speeds increase, CAS latencies also increase, effectively nullifying some of the speed gain.

What is the best CAS latency for gaming?

Is higher CAS latency better?

What is CAS latency? CL: Short for CAS latency, refers to how long the computer needs to wait before it can actually start reading data from memory. Therefore, for two memory modules with the same frequency, a higher CL means a longer delay time.

Is there a big difference between 16 and 18 CAS latency?

In terms of CAS latency and speed, CL16 is a little better than CL18. But from the prices, the CL16 is more expensive than the CL18. So, if your budget is not too much, you can choose CL18 for your computer.

RANT: THE CAS LATENCY TIMING DOESN'T MATTER AS MUCH AS YOU THINK IT DOES

Is CL18 3600 faster than CL16 3200?

The difference will be extremely minimal.

You can see that the effective latency is the same. 3600 CL18 is the same latency as 3200 CL16. These are MASSIVE numbers, and it takes some incredible demands to reach a maximum throughput that will be bottlenecked by DDR4.

Which is faster 3200MHz CL16 or 3600MHz CL18?

The latency of 3200MHz CL16 and 3600MHz CL18 is the same (both have a CAS Latency of 10ns) but the higher frequency of the 3600MHz RAM would give it the advantage.

What is the CAS latency for 3600MHz?

The 3600MHz unit, for instance, has a CAS latency of 18 whereas the 3200MHz unit is a C16 kit.

What is the lowest CAS latency in RAM?

RAM speed vs.

DDR3 RAM usually has a CAS latency of 9 or 10, while DDR4 will have a CAS latency of at least 15. However, because of its faster clock speeds, the newer standard has better performance overall.

What is a good CAS latency for DDR4?

A stick of DDR4-3600 RAM with a CAS of 15 has a true latency of 8.33 nanoseconds, while a same-size/same-speed stick with a CAS of 19 has a latency of 10.56 nanoseconds. In this case, the DDR4-3600 RAM with a CAS of 15 is objectively better than the DDR4-3600 RAM with a CAS of 19.

Is CAS latency 14 better than 16?

Overall, the lower CAS latency the better the performance. It's not the only metric you should be looking at as all other specs of RAM dictate the overall performance. Edit: the difference isn't massive. In games, a few frames of a difference at best.

Is 32 GB RAM overkill?

32GB of RAM is considered high and is generally overkill for most users. For most everyday use and basic tasks such as web browsing, email, and basic office work, 8GB of RAM is more than enough. Even for gaming or video editing, 16GB is typically sufficient.

Is 3600MHz RAM better than 3200MHz?

3200MHz or 3600MHz, which is better? If you use your computer for less resource-dependent tasks and applications, then 3200MHz RAM will be great for you. However, if you use your PC for gaming, video editing, or other applications that require high speeds, you'll want to opt for 3600MHz RAM.

Does high latency reduce FPS?

Performance with 60 FPS frame rate was 14% higher than 30 FPS, but the difference between 45 and 60 FPS was not significant. Latency alone had lower impact than the corresponding frame rate difference. While both factors impact performance, frame rate had a larger effect than the latency it introduces.

Is 36 CAS latency bad?

The higher CAS numbers keep the real time latency similar to the real time latency for DDR3/4, but the RAM is much faster in all other ways. They will not go down to anything close to 10-20 over time. 36 is pretty good already.

Why is my CAS latency so high?

If your CAS latency is higher than what is advertised (e.g. latency is advertised as 3000c15-18-18 but runs at 3000c16-18-18), this is because of a BIOS setting that helps with memory stability on Ryzen systems. You can disable this setting so that the memory runs at its rated speed.

Is 32 CAS latency good?

It's important to note that while a CAS latency of 32 is very impressive for default operation, it's just one timing. The Trcd, Trp and Tras also play a part, and these are set at 39-39-102 though we're sure these can be lowered with some tweaking or adventurous voltage application.

What is the CAS latency for DDR4-3200?

Calculating RAM Latency or CAS Latency

However, because advertised CAS Latency is measured in clock cycles, we need to account for memory speed to get a real-world CAS latency in nanoseconds. So, say we have a DDR4-3200 CL16 memory kit. You get a latency in nanoseconds with (16*2000)/3200 = 10ns.

Is higher CAS latency better for DDR5?

For CAS latency ratings, lower numbers are better. A DDR4-3200 CL20 module, for instance, has a CAS latency rating of 20. Most DDR5 modules have CL40 CAS latency, which negates DDR5's high clock speeds.

Is 3600 CL16 better than 3600 CL18?

CL16 at 3200 is exactly the same latency as CL18 at 3600, because 16/32=0.5 and 18/36=0.5*. So the 3600 memory has the same CL latency and faster data rate, making it strictly faster.

Why is DDR5 CAS latency so high?

DDR5 inherently has more bandwidth by the way it was designed. As for why the timings are so much looser on DDR5, that's the way it goes for every new DDR release.

What is the lowest CAS latency DDR4?

Skill announces DDR4 RAM with lower latency. Specifically, the company has announced the RAM memories of the Trident Z RGB, Trident Z Royal and Trident Z Neo families. These three families of drives arrive with CL14 latency, the lowest latency on the market for 3200MHz.

Is there a big difference between 3200MHz and 3600MHz in gaming?

If you are gaming on a Ryzen CPU (or even an intel CPU) then the 3600MHz will be far more important. If you are doing large workstation tasks like complex video editing then the 32GB of RAM will be very useful.

Is 3200 CL14 faster than 3600 cl16?

3600 CL 16. AMD showed equal latencies as 3200 CL14, but then you have more bandwidth and faster IF. Not if you disable Geardown mode, may not be stable if disabled though.

Is it okay to run 3600MHz RAM at 3200?

It is completely fine to pair 3600MHz with 3200MHz. The 3600MHz will just run at a maximum of 3200MHz.
