Is higher CAS latency better for DDR5?

Most DDR5 modules have CL40 CAS latency, which negates DDR5's high clock speeds. It's faster at completing tasks, but it takes longer for the RAM to register it needs to perform a task. So, that DDR4-3200 CL20 RAM will have snappier performance than a DDR5-4800 CL40 module.

What latency is good for DDR5?

Fun facts on latency:

From the introduction of DDR memory all the way to the launch of DDR5, standard JEDEC memory's true memory latency has stayed consistent in the range of 13 to 16 ns. Standard JEDEC memory's system latency has stayed consistent in the range of 90 to 100 ns.

Is higher CAS latency better for RAM?

What is CAS latency? CL: Short for CAS latency, refers to how long the computer needs to wait before it can actually start reading data from memory. Therefore, for two memory modules with the same frequency, a higher CL means a longer delay time.

What makes DDR5 faster?

In addition to higher bandwidth and improved power consumption, DDR5 will also offer higher capacity per memory module. Memory density and banks go hand-in-hand. When you increase the density, you also have to augment the number of banks to accommodate the extra capacity.

Which DDR5 RAM has the lowest latency?

Skill has announced the release of the fastest DDR5 memory kit to date (opens in new tab). At DDR5-6800 with a CAS latency of 32, the kit offers a tantalizing combination of high speed and low latency.

RANT: THE CAS LATENCY TIMING DOESN'T MATTER AS MUCH AS YOU THINK IT DOES

Why is DDR5 CAS latency so high?

DDR5 inherently has more bandwidth by the way it was designed. As for why the timings are so much looser on DDR5, that's the way it goes for every new DDR release.

What is the quickest DDR5 RAM?

Corsair Vengeance RGB DDR5 32GB 5,600MHz C36

This DDR5 RAM has more on offer than just great looks. It's also fast, stable and overclocking ready. A great choice for modern gaming PC builds. Corsair's Vengeance RGB has long been a favourite with PC gamers thanks to its clean aesthetic and great lighting.

How do I optimize my DDR5?

Does DDR5 affect gaming performance?

One of the best DDR5 kits will still offer a great gaming experience, but the delicate balance of speed and latency puts high-end DDR5 in a precarious position. On one hand, faster DDR5 can offer practical differences in some games, but on the other, even faster kits can result in lower performance.

Is DDR5 4800MHz good?

The 4800MHz launch speed is comparable to DDR4 memory speeds under extreme performance and is two times faster than 3200MHz. Since it's optimised for multitasking, your computer will be more responsive.

Does CAS latency make a big difference?

CAS latency is an accurate indicator of real world latency performance. As speeds increase, CAS latencies also increase, effectively nullifying some of the speed gain.

Is CAS latency 16 better than 18?

In terms of CAS latency and speed, CL16 is a little better than CL18. But from the prices, the CL16 is more expensive than the CL18. So, if your budget is not too much, you can choose CL18 for your computer.

Is higher CAS latency bad?

The lower the CAS latency, the better

Another way to think of it is how many RAM clock cycles it takes for the RAM to output data called for by the CPU. A RAM kit with a CAS of 16 takes 16 RAM clock cycles to complete this task. The lower the CAS latency, the better.

Is CAS latency 36 good?

The higher CAS numbers keep the real time latency similar to the real time latency for DDR3/4, but the RAM is much faster in all other ways. They will not go down to anything close to 10-20 over time. 36 is pretty good already.

Does DDR5 run hotter than DDR4?

That, combined with the improved performance and much greater density of the memory chips, means DDR5 runs hotter than DDR4. This means you'll want to make sure you have compatible heat sinks before installing DDR5 RAM .

Is DDR5 overkill?

Although DDR5 RAM sticks are impressive, to say the least, they are overkill for most gaming applications.

Why is DDR5 not faster than DDR4?

1. DDR5 Scales to 8.4 GT/s. You can never have enough memory bandwidth, and DDR5 helps feed that insatiable need for speed. While DDR4 DIMMs top out at 3.2 gigatransfers per second (GT/s) at a clock rate of 1.6 gigahertz (GHz), initial DDR5 DIMMs deliver a 50% bandwidth increase to 4.8 GT/s.

Does DDR5 need XMP?

Q: Does DDR5 have XMP? A: Yes! DDR5 will come with XMP 3.0, while DDR4 has XMP 2.0 and DDR3 has XMP 1.3. Up to two preconfigured profiles are included on DDR5 modules, and you can save up to two custom XMP profiles directly to the module.

What is the highest overclock for DDR5?

Gigabyte DDR5 memory has been overclocked to 11136 MT/s.

Is there DDR6 RAM?

As of February 2023, DDR6 is confirmed to be in development, with Samsung announcing at its Tech Day that DDR6 is expected to arrive as modules for commercial use in 2025.

Is slow DDR5 better than fast DDR4?

Either way, even the fastest DDR4 cannot reach the same high speeds that DDR5 can. Another of DDR5's key improvements over DDR4 is its data transfer rate. For Intel's 12th generation “Alder Lake” processors, DDR4 will run at speeds up to 3200 Megatransfers per second (MT/s), and DDR5 will run up to 4800 MT/s.

What MHz does DDR5 start at?

On the other hand, DDR5 starts at a range of 4800 MHz – 5600 MHz, and is being referred to as DDR5-4800 SDRAM. This is a whopping 1.8 times improvement over DDR4.

What is the best CAS latency?

When it comes to CAS latency, lower is better. Look out for CL16/CL18 or better, as these kits offer the responsiveness we want for gaming.

What is the ideal CAS latency for Rams?

A CAS cycle latency of 15 is best for all mid-range gaming systems, and it is perfectly acceptable for most high-end gaming systems. The CAS latency stands for Column Access Strobe latency, which refers to the delay between instruction to transfer data and the response time of the execution.

Is CAS latency 14 better than 16?

Overall, the lower CAS latency the better the performance. It's not the only metric you should be looking at as all other specs of RAM dictate the overall performance. Edit: the difference isn't massive. In games, a few frames of a difference at best.
