Question: Is Lower First Word Latency Better?

What is a good CAS latency?

RAM latency.

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?

The recommendation on RAM upgrading is to use two RAM pieces with the sam speed (same latency) and same volume. Then, the system will work smoothly and best performance. So, it is not safe to upgrade PC with the RAM pieces that is different CAS latency.

Is faster RAM worth it?

Faster RAM will give your PC better performance in certain specific benchmarks, but in terms of actual benefit to most users, having more RAM available is almost always better than having faster RAM. … It also means that overclocking RAM in the system BIOS is rarely worth the effort.

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.

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.

How much RAM do I need for gaming?

8 GB is currently the minimum for any gaming PC. With 8 GB of RAM, your PC will be running most games without any problem, though some concessions in terms of graphics will probably be required when it comes to the newer, more demanding titles. 16 GB is the optimal amount of RAM for gaming today.

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 G Skill good RAM?

G. Trident Z RGB DDR4 RAM features CAS latencies between 14 and 19 which is awesome enough, but with speeds up to 4,266, it’s almost perfect. No matter your aesthetic, it’s hard to argue with the G. Skill TridentZ RGB as the best RGB RAM.

What is the best RAM timing for gaming?

And if you need help deciding how much RAM you need, we can help on that front as well. But the short answer is, for most users and gamers, 16GB is the sweet spot.

How do I check my RAM latency?

How do I check my CAS latency?Download CPU-Z application from the application and navigate to Memory tab.Read the text in front of CAS# Latency (CL)Done…!

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.

What is first word latency?

CAS Latency is the measured delay between the moment the memory controller queries or asks the RAM for information, and the time at which it becomes available. The smaller the CAS number is, the faster the RAM can provide data to the memory controller.

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.

What are good memory timings?

Your millage may vary depending on the word burst allowance being used in a transfer, so these are just basic timing numbers. CL 8/9 is pretty good timing for 1600 sticks, a bit faster than 11. And a good read on what DDR4 is all about with respect to DDR3 and future DRAM configurations…

Does MHz of RAM matter?

RAM frequency is measured in MHz and usually immediately follows the DDR version in the RAM spec. For example, 8GB DDR4-2400 RAM is running at a frequency of 2400MHz. … This is why though higher frequency RAM is technically faster, that additional speed often does not translate into better actual real world performance.
