What do memory latency numbers mean?
Memory timings or RAM timings describe the timing information of a memory module.
These parameters (as part of a larger whole) specify the clock latency of certain specific commands issued to a random access memory.
Lower numbers imply a shorter wait between commands (as determined in clock cycles)..
How much RAM do I need for gaming?
16GBGet at least 16GB of RAM to play modern games, and more if you multitask.
Does CAS latency affect gaming?
CAS latencies and RAM speed for gaming are irrelevant as long as they are relatively tight, and at native speed. For rendering RAM frequency is more important, but again, CAS latencies play a very small part here, don’t seriously take them into account when buying RAM.
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.
Can I mix ram with different CL?
Yes you can use two different brands of RAM in a PC but you should make sure that they both are compatible for your PC. For example you should make sure which RAM will your mobo supports for example if your motherboard support ddr3 then you should insert both of your RAM must be ddr3.
Can I overclock 1600mhz RAM?
Of course you can overclock your RAM but you typically end up having to sacrifice latency which probably has more of an impact on the performance than the actual frequency. IMHO you don’t get a noticeable difference in system performance from overclocking your RAM but you definitely can affect your system’s stability.
Does first word latency matter?
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.
How do you calculate first word latency?
Due to this, the first word latency is: First word latency = (tRCD + tCL + BL)/(effective transfer rate/2000) First word latency = (16 + 16 + 4)/(2400/2000) = 30ns This is much higher then CAS latency for this situation which is 13.33ns.
Can you mix RAM with different timings?
RAM will run slower but not always faster..Voltage is the most critical thing and should match, or be within 0.1V of each other at the most, so you’re good there.. When the BIOS detects differing RAM speed/timing/voltage it should use the lower/slowest settings of the two when on Auto settings.
What do latency numbers mean?
In a computer network, latency is defined as the amount of time it takes for a packet of data to get from one designated point to another. In more general terms, it is the amount of time between the cause and the observation of the effect. As you would expect, latency is important, very important.
What RAM latency is good for gaming?
1. TEAM XTREEM ARGB 16GB DDR4-3600MHz C14. The best RAM 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.
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.

What is network latency?
In a network, latency measures the time it takes for some data to get to its destination across the network. It is usually measured as a round trip delay – the time taken for information to get to its destination and back again. … Latency is usually measured in milliseconds (ms).
What is a good first word latency for 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.
Does RAM Latency have to match?
If it doesn’t match, the faster RAM will downclock to match the slower RAM.
How do you calculate latency?
How to Measure Network Latency. Once you type in the tracert command, you’ll see a list of all routers on the path to that website address, followed by a time measurement in milliseconds (ms). Add up all the measurements, and the resulting quantity is the latency between your machine and the website in question.
Is lower RAM latency better?
Latency deals with how fast the RAM module can access its own hardware, and in this specific case, the lower the numbers, the better. Lower latency means faster data access, thus faster data transfer to the CPU, and faster operation of your computer overall.
Is lower first word latency better?
The lower the CAS, the faster the RAM—and consequently, the more expensive. 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 CAS latency more important than speed?
CAS latencies are an inaccurate indicator of performance. … As speeds increase, true latencies decrease and/or remain roughly the same, meaning faster speeds deliver better performance.
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.
What is cl17 RAM?
CL means cas latency, it tells you how many clock cycles it takes for a certain piece of data to be available after the memory controller requested it from the RAM. … But Cl 17 is more expensive?
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.
