Is a lower 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.

What is a good CAS latency?

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 18 better than 16?

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.

Is faster speed or lower CAS latency better?

In contrast, semiconductor engineers know that: CAS latencies are an inaccurate indicator of performance. True latency is best measured in nanoseconds. As speeds increase, true latencies decrease and/or remain roughly the same, meaning faster speeds deliver better performance.

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.

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

Is CL18 faster than CL14?

3600 cl18 will give you higher frame rates and a lower effective latency but the 3200 cl 14 will give you better frame times. If you use a 3200MHz RAM the memory clock (also called MCLK) and FCLK has to be lowered to 1600MHz directly affecting the speed of data exchange inside the CPU.

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 the best RAM CAS latency?

What CAS latency is best for DDR5?

Most DDR5 modules have CL40 CAS latency, which negates DDR5's high clock speeds. It's faster at completing tasks, but it takes longer for the RAM to register it needs to perform a task.

Which is faster 3600 CL18 or 3200 CL16?

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.

What is the difference between 3200 mhz CL16 and CL18?

Is there any major difference between CL16 and CL18 Ram for Ryzen 5000? 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.

Which is better 3200 CAS 14 or 3600 CAS 16?

On Ryzen, 3600 CL16 is better than 3200 CL14 because it lets you run the Infinity Fabric clock higher in 1:1 mode, which offsets the minor increase in RAM latency. As for which kit you should get, it comes down to price.

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.

Is 32GB 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.

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.

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.

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.

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.

Which is better 3200 CL16 or 4000 CL18?

4000MHz CL18 is much faster, in both bandwidth and latency. Memory bandwidth is directly proportional to clock frequency. DDR4–3200 has 25.6GB/s of bandwidth (per memory channel), while DDR4–4000 has 32GB/s of bandwidth (per memory channel). Memory latency is measured in clock cycles.

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 3000MHz CL15 better than 3200MHz CL16?

TL;DR: they are the same. If you divide the MHz by the latency, you can compare the numbers between different sets. Higher = better. 3000MHz CL15 and 3200MHz CL16 both divide to 200.

Is CL15 faster than CL16?

CL16 has a CAS latency of 16 and CL15 has a CAS latency of 15 (don't know how significant this is), but the CL16 version has a speed of 3200 while the CL15 version has a speed of 3000.

Is 16gb 3600MHz RAM better than 32GB 3200mhz?

Well, that depends on what you are doing. 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.
