What is the latency of 12900K RAM?

Intel Core i9-12900K Cache and Memory Benchmark

You can see that the memory latency is 76.7ns, L1 cache latency is 1ns, L2 cache latency is 3.5ns and L3 cache latency is 17.6ns.

What is the CAS latency of DDR5 RAM?

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.

What is the default RAM speed for 12900K?

Alder Lake arrives with native for both DDR4 and DDR5 memory formats. The default supported data rates are DDR4-3200 and DDR5-4800, respectively.

How many MHz is i9 12900K?

Intel Core i912900K Processor 30M Cache up to 5.20 GHz Product Specifications.

What temp should 12900K run at?

Core i9-12900K temperature can hit 100°C easily with core-heavy workload. To dissipate the heat efficiently, a powerful CPU cooler is necessary, especially if you plan to overclock. A stock Core i9-12900K consumes 220~256W power with multi-threaded workload such as Blender and Cinebench.

Memory LATENCY SCALING BENCHMARKS 😱✔️😱✔️

Is i9 12900K the fastest CPU?

Intel has unveiled the Core i9-12900KS "Special Edition" CPU claiming it's "the world's fastest desktop processor." Like the Core i9-12900K, it comes with 16-cores, including eight Performance cores and eight Efficient cores, along with 24 threads and 30MB of L3 cache.

What does CAS latency mean on 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 is optimal RAM speed?

In terms of memory speed, you should look for DDR4 memory that operates close to or above 2,400MHz—or 2400MT/s as it'll appear on the packaging and online. Users purchasing DDR3 RAM should look for memory operating at 1,866MHz at least, and the closer to 2,000MHz the better.

Does RAM speed matter for Alder Lake?

In benchmarks focusing specifically on frequency and latency on both DDR4 and DDR5 memory, Techspot tested a variety of applications and games on Intel's 12th-gen Alder Lake CPUs. The TL;DR here is that the frequency and latency usually doesn't matter much.

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.

Which RAM latency is good?

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.

Which latency is best for RAM?

Usually CL of 16 - 18 is normal and clock speed depends on CPU. Ryzen 3xxx works with 3600 while 5xxx goes with 4000. Intel depends. In any case, try to get memory with lower latency numbers, eg 16–18–18–36 is good one.

What is the best RAM timing for DDR5?

For an Intel DDR5 system, a good kit around the 5200MHz range will be fine, while for a high-end system, you'll want something a little faster at 6000MHz or even 6400MHz if you really want to get every last drop of performance.

What is the best RAM frequency Alder Lake?

DDR4-3600 performed the best in gaming. The difference between DDR4-3600 and DDR4-2133 was 8%, whereas there was less than a 1% margin between DDR4-3600 and DDR4-3200.

Is RAM speed or latency more important?

True latency is a much better indicator of performance, as it takes the number of clock cycles and the length of each clock cycle into account.

Does RAM latency matter?

Yes, they do. However, CAS Latency is still the most commonly used metric to compare memory latency because it more directly affects (immediately) how fast your RAM module responds to a request. That said, some engineers do argue the benefits of relying instead on First Word latency when it comes to memory.

Will faster RAM increase FPS?

And, the answer to that is: in some scenarios and depending on how much RAM you have, yes, adding more RAM could increase your FPS. Games require a certain amount of memory to run. The amount of memory that games require to run can vary from game to game.

What happens if I use RAM of a faster speed than the CPU supports?

If you try to install and use a RAM module that operates beyond the speeds that the CPU and the motherboard can support, it will lead to unstable system performance and/or boot issues. Mismatched memory will do this as well.

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.

Is 32 CAS latency good?

It's important to note that while a CAS latency of 32 is very impressive for default operation, it's just one timing. The Trcd, Trp and Tras also play a part, and these are set at 39-39-102 though we're sure these can be lowered with some tweaking or adventurous voltage application.

What RAM latency is good for gaming?

How fast should RAM be for a gaming PC? Generally, we'd recommend you stick with two DDR4 modules for a dual-channel build, each with a minimum of 3,000MHz clock speed. That should ensure you're getting the most out of the best CPUs for gaming (opens in new tab).

What is too hot for a i9 12900K?

My rules are that the processor, while under load, should keep its sustained temperatures below 90 (all temperatures in Celsius). Very short duration spikes up into the 90s are ok, but should not be reaching 100c (the typical Tjmax).

Is i9 12900K overkill for gaming?

An Intel Core i9 CPU can provide more than enough performance for gaming, but it might be considered overkill for most gamers. These processors are designed for tasks that require high levels of parallel processing power such as video rendering, 3D animation, and complex data analysis.

Is i9 12900K high end?

Hardware specifications. The Core i9-12900K is one of Intel's high-end Alder Lake desktop processors. In fact, it's probably next only to the Intel Core i9-12600KS, which can boost its frequency to up to 5.50 GHz.

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.
