How do memory timings work?

The memory timings are given through a series of numbers; for instance, 4-4-4-8, 5-5-5-15, 7-7-7-21, or 9-9-9-24. These numbers indicate the amount of clock cycles that it takes the memory to perform a certain operation. The smaller the number, the faster the memory.

Are RAM timings important?

These numbers are known as the timings of the RAM kit. Inherently, as they represent the latency, lower is better when it comes to timings. These four numbers represent what are known as “Primary Timings” and have the most significant impact on the latency.

Is lower RAM timings better?

The lower the CAS latency, the better A RAM kit with a CAS of 16 takes 16 RAM clock cycles to complete this task. The lower the CAS latency, the better. It’s important to note that two different RAM kits with the same data transfer rate, for example DDR4-3200, can have different CAS timings.

What are the 4 memory timings?

Timings are most commonly broken down to the four values: CAS Latency (CL), Row Column Delay (tRCD), Row Precharge Time (tRP), and Row Active Time (tRAS).

What is memory timing mode?

Hi. The DRAM Timing Mode option controls how the memory timing settings are configured. The Advance DRAM Configuration link activates with this option set to Link or Unlink.

Does RAM timing affect performance?

Like 13thMonkey said, on a Ryzen based system you will notice a slight decrease in performance when using 2133 or 2400 MHz RAM vs 3000 or 3200 MHz RAM. On my PC (see my signature for my full specs), I do notice a difference when I run my RAM at 2133 MHz even when just web browsing, etc.

What is CAS and RAS latency?

The RAS to CAS delay determines the time between memory accessing RAS (Row Address Strobe) and CAS (Column Address Strobe). The lower the number, the better, but tRCD timing plays a less significant role in overall performance compared to CAS latency.

How do I adjust my RAM timings?

What is Realtime memory timing?

Real time memory timings allows you to change timings in OS using something such as MemTweakIT. It’s useful for benching on that board since tXP isn’t shown when tXP is apparently a very performance impactful timing according to what I have been told.

Is it better to have faster RAM or more RAM?

As we said before, the faster your RAM, the more data can be fed to and from your CPU, storage, and in the case of integrated graphics that use system RAM, the graphical processing unit (GPU) every second. While RAM speed is important, it’s better to have more RAM than faster RAM.

Does RAM speed have to match?

No. RAM does have to match the type. If the motherboard requires DDR3 then you need to use DDR3. Most these days use DDR4.

What is tRC timing?

tRC – Row Cycle Time: The minimum time interval between successive ACTIVE commands to the same bank is defined by tRC. tRC = tRAS + tRP.
