Understanding what CAS latency is and how it works is important to deepening your knowledge of RAM.
It’s shown in varying ways, so the listings may not always be consistently showcased from manufacturer listings.
What is CAS latency?
It’s measured in clock cycles, with a lower amount of cycles meaning the RAM is more responsive.
That’s where the differences inDDR5 vs DDR4RAM come in.
While DDR5 is faster and achieves higher frequencies, it will have a longer CAS latency.
Different frequencies and capacities will have varying latency.
This can be seen by looking at the varying CAS latency from top-end DDR5 kits.
The Corsair Dominator Platinum RGB has different CAS latency depending on the variant, for instance.
The 32GB 6000MT/s kit has a CAS latency of 36 (36-38-38-76).
However, the 64GB 6200MT/s version has a CAS latency of 32 (32-38-38-80).
So things aren’t always consistent between models, even from the same line.
What are CAS Timings?
Does RAM speed affect CAS latency and timings?
Does CAS latency impact performance?
Even thebest RAMkits on the market may not make a massive difference when it comes to gaming performance.
Performance is dictated far more by your graphics card and processor than the speed of your RAM.
Every manufacturer is different, and the same line of hardware will not necessarily be consistent.
How do I test my RAM’s latency?
it’s possible for you to also easily find it by searching for it manually in the start menu.
