Which latency is best for memory?
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.
Is higher memory timing better?
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 a latency of 17 good?
20ms or less is actually an excellent latency! This is what diehard, hair-trigger, gamers are looking for. A rate from 20 to 100 ms seems to be acceptable latency for gaming, and really won’t affect everyday online play. Anything 100-150 ms is workable, but probably noticeable.
Is higher or lower latency better?
Since this usually happens pretty quickly, latency is measured in milliseconds. Bottom line: A lower latency is better. Pro tip: To test latency, your computer can send a small bit of data to a remote server to measure the round-trip time.
What is a good number for latency?
20ms to 40ms
What is good latency? So now that we see high latency means a delay in data transmission, what is considered “good” latency when it comes to online games? Typically, anything at 100ms is acceptable for gaming. However, the 20ms to 40ms range is considered optimal.
Is 9ms latency good?
Latency is measured in milliseconds, and indicates the quality of your connection within your network. Anything at 100ms or less is considered acceptable for gaming. However, 20-40ms is optimal.
Is 10 ms latency good?
Ping amounts of 100 ms and below are average for most broadband connections. In gaming, any amounts below a ping of 20 ms are considered exceptional and “low ping,” amounts between 50 ms and 100 ms range from very good to average, while a ping of 150 ms or more is less desirable and deemed “high ping.”
Is 16 CAS Latency good?
DDR4 3200 CAS 16 is still well within the range of ‘fine’ but it’s slower. You’d have to pay attention to both numbers.
How to calculate memory latency with CL = 7?
A memory with CL = 7 will provide a 22.2% improvement on memory latency over a memory with CL = 9, considering that both are running at the same clock rate. You can even calculate the time the memory delays until it starts delivering data. The period of each clock cycle can be easily calculated through the formula: T = 1 / f
Is there really a latency rating for memory?
The myth is perpetuated by the method upon which latency labels are based: Clock cycles. Consider the latency ratings of the three most recent memory formats: Upper-midrange DDR-333 was rated at CAS 2; similar-market DDR2-667 was rated at CAS 4 and today’s middle DDR3-1333 is often rated at CAS 8.
Does every new memory format have a latency penalty?
There’s a myth that every new memory format brings with it a latency penalty. The myth is perpetuated by the method upon which latency labels are based: Clock cycles.
What is CAS latency and why does it matter?
Consider the most famous parameter, which is called CAS Latency (or CL or “access time”) that tells us how many clock cycles the memory module will delay in returning data requested by the CPU. A memory module with a CL 9 will delay nine clock cycles to deliver a requested data, whereas a memory module with a CL 7 will
