What is the meaning of a RAM’s CAS latency or CL timing? Latency and RAM performance explained.

For high-level performance, you’ll need memory above 4,000MHz with a latency of around CAS (Column Address Strobe or Signal) 15-18 or less. When buying RAM, you might see this listed as CL 16 (Column Latency 16), for example. For regular users, this is unlikely to make a meaningfu...
Example: if the speed rating of a standard module and a gaming module is the same (i.e. DDR4-2666) but the CAS latencies are different (i.e. CL16 vs. CL19), then the lower CAS latency will provide better performance The difference between the perception of latency and the truth of...
Latency: CAS (Column Address Strobe) latency is an important factor in RAM performance. Lower latency numbers generally indicate better performance. DDR4 latencies typically range from CL14 to CL22. Voltage: Standard DDR4 RAM operates at 1.2V, with some high-performance modules using up to 1.35...
Every one of these modules is rated at 3200 MHz with a CAS Latency of 16. Corsair Vengeance LPX 16GB (2 x 8GB) DDR4 3200 MHz CL16 Corsair’s Vengeance LPX is probably one of the most widely-used RAM kits out there and hence, is supported by most boards. All the motherboards that...
The absolute latency of a RAM stick (measured in nanoseconds) is calculated by multiplying the reciprocal of the clock frequency (in cycles) divided by two. For example, a RAM kit with a clock frequency of 3,600 MHz and a CAS of 16 cycles will have an absolute latency of 16/(3,600,...
The kit includes two 8GB modules rated with XMP values of DDR4-3400 CAS 16-18-18-36. Those last three numbers aren’t great, but DDR3 lovers must remember that 16 cycles at a 3400 MHz data rate have the same latency time as eight cycles at 1700 MHz. So this kit has an excellent...
Also, the lower the default CAS latency setting used by the manufacturer (e.g. 3200 MHzCL14), the more likely you are to achieve good results. This is not a strict requirement, because even some 3000 CL16 RAM kits can achieve 3600 MHz CL17 without a hassle, but you’re more likely...
CAS Latency is measured in clock cycles. Typically, latency may not be written directly on your server RAM. Instead, it might be mentioned within a series of numbers that are printed on your server RAM. Basically, lower numbers are better. The lower the number, the lower the latency and,...
