Quick Answer: What Is A Good CAS Latency For Gaming?

What is a good CAS latency?

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..

How do I lower my CAS latency?

A typical rule of thumb for this value is : Active Precharge Delay = CAS-Latency + RAS Precharge Delay + 2 (added as a safety margin). As with other experimental value tweaks, reduce this number by one clock cycle at a time to determine if faster values work, as is often the case.

Does RAM Latency affect FPS?

Lower latency to read/write access with a better clock cycle time adds a half % FPS performance on average. The 4000 mhz ram is a fine example of what Corsair is saying. Speed trumps CAS as shown with CAS timings in the high teens/low 20s.

What is more important Cl or Mhz?

Both are important. Keep in mind though that latency is measured in clock cycles so 3200 mhz cl16 ram would have much lower latency than 1600 mhz cl16 ram while having much higher bandwidth.

Can you change RAM latency?

Your RAM has built-in settings, instructions that your motherboard can (hopefully) read. These instructions include frequency, timings (latency) and voltage. One of these settings is called XMP, but it is not normally the default. So yes, you should be able to activate the XMP without digging too far into the BIOS.

Does CAS latency matter for gaming?

It matters a bit. It’s stated in terms of clock cycles, not time, so higher frequency and higher CAS number isn’t necessarily longer latency.

Is 19 CAS latency bad?

For 16GB RAM at 3600mhz, you’ll find options ranging from a CAS latency of 15 to 19. … When deciding between RAM of different clock speeds, the RAM with the higher clock speed is superior; but when choosing between RAM of identical clock speeds, the RAM with lower CAS latency is faster.

How do I check my RAM latency?

How do I check my CAS latency?Download CPU-Z application from cpuid.com.Open the app and navigate to the Memory tab.Read the text in front of CAS# Latency (CL)Done…!

What does CAS latency mean?

Column Address StrobeCAS Latency (CL) stands for Column Address Strobe. This is the number of clock cycles that pass from when an instruction is given for a particular column and the moment the data is available. In general the lower the CAS latency the better within a given memory technology (DDR, DDR2 or DDR3).

Is CAS latency important?

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.

Is CL18 better than CL16?

3200mhz CL18 is basically slightly overclocked 3000mhz CL16 with worse timings which means there is a chance that you can overclock 3000mhz CL16 to 3200mhz 18CL. So it doesn’t really matter which one you get.

Does MHz of RAM matter?

RAM frequency is measured in MHz and usually immediately follows the DDR version in the RAM spec. For example, 8GB DDR4-2400 RAM is running at a frequency of 2400MHz. … This is why though higher frequency RAM is technically faster, that additional speed often does not translate into better actual real world performance.

Can you mix RAM with different CAS latency?

CAS Latency The rule is simple: the lower the CAS Latency is, the faster it operates. It is definitely not recommended to mix two RAMs with different CAS Latencies.

Does CAS latency matter for Ryzen?

No. Timings measure latency. The speed/cas (3200/16 = 200) is essentially the responsiveness of the ram. Yes this matters.

Is CAS latency 22 bad?

Cas latency at 22 is pretty bad relative to what’s out there. … Good DDR4 3200 has CL14 and decent 3200 has CL 16. Maybe try for ~2800 with a much lower latency.

Do RAM timings matter for Ryzen?

Ryzen processors have historically proven more sensitive to RAM speed than their Intel Core counterparts, so we expect to see even greater performance gains from high frequency RAM on our AMD test bed. As in part one, in-game frame-rates are the primary focus here, with three CPU-heavy games tested.

How much RAM do I need for gaming?

8 GB is currently the minimum for any gaming PC. With 8 GB of RAM, your PC will be running most games without any problem, though some concessions in terms of graphics will probably be required when it comes to the newer, more demanding titles. 16 GB is the optimal amount of RAM for gaming today.

Does RAM Latency have to match?

The recommendation on RAM upgrading is to use two RAM pieces with the sam speed (same latency) and same volume. Then, the system will work smoothly and best performance. So, it is not safe to upgrade PC with the RAM pieces that is different CAS latency.
