WebNov 2, 2024 · The CL or CAS latency is how many clock cycles it takes to access data and make it available to be transferred. So those are the two factors. The speed of the RAM also affects real-world latency in nanoseconds - i.e. a DDR5-7000MT/s CL 40 actually has a lower latency than DDR4-2666 CL18. (CAS latency/RAM clock speed) x 2000 = … WebOct 30, 2024 · It's worked out as follows: 40 / 2400 (rated Mhz divided by 2), x 1000 = 16.6ns. This is a fair bit more than my DDR4000 CL 19 kit, with a total latency of 9.5ns. What this tells me me, is that a DDR5 4800mhz module would need a CAS Latency of 22, for a reduced latency of 9.16ns.
