Quick Answer: Why Is Ddr4 CAS Latency Higher?

Is 3600MHz RAM better than 3200?

3200MHz CL14 RAM would be a “better” choice over 3600MHz CL16.

While Ryzen does like fast RAM, its only to a point.

At 3200MHz the speed gain itself likely wont be significant enough to warrant the increase in latency..

Does CAS latency matter?

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.

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 I use 1333mhz and 1600MHz RAM together?

Yes, you can mix 1333 and 1600 MHz RAM sticks, however the system will downclock all RAM to the speed of the slowest stick. For best performance, try and buy RAM that is the same speed or faster.

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.

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.

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 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.

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.

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 higher CAS latency better?

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

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.

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).

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.
