Quick Answer: Is CAS Latency More Important Than Speed?

Is CAS latency 16 good?

The lower the CAS latency, the better Another way to think of it is how many RAM clock cycles it takes for the RAM to output data called for by the CPU.

A RAM kit with a CAS of 16 takes 16 RAM clock cycles to complete this task.

The lower the CAS latency, the better..

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.

Does CAS latency matter for Intel?

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.

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.

Is 32gb RAM overkill?

32GB, on the other hand, is overkill for most enthusiasts today, outside of people who are editing RAW photos or high-res video (or other similarly memory-intensive tasks).

Is cl16 better than cl18?

Lower cl is better especially when there is only 200mhz difference I would however say it would be better performance wise to go with 2 4gbs sticks. 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.

Is higher CAS latency better?

In general the lower the CAS latency the better within a given memory technology (DDR, DDR2 or DDR3).

How much does CAS latency affect performance?

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.

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.

What is the best CAS latency for gaming?

With a CAS latency of 14, the Team Xtreem kit leads the way in low-latency RAM favoured by gaming PCs, especially AMD Ryzen rigs. As such, it takes the top spot as our pick for the best RAM for gaming.

Is 3600mhz RAM good?

Is 3600Mhz Ram actually worth it? For most people’s usage, including gaming, increasing your memory speed is not typically worth it. This includes using memory in pairs or quads as supported by your motherboard. You’ll see very little performance gain.

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.

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.

What is the lowest CAS latency?

World’s Lowest Latency DDR4-4000 Memory Kit at CL15 Previously, the best CAS latency that memory kits at the DDR4-4000 level could achieve was at CL17.
