RAM First Word Latency Table (nanoseconds)

Latency is measured in nanoseconds, which is a combination of frequency and CAS. Both frequency increases and latency decreases result in better system performance (when latency is the same, always prefer higher frequency if possible).

CAS (clock cycles) Lower latency means faster memory.

Distribution of First Word Latencies for Similar RAM Modules

The histogram below shows the distribution of first word latencies (in nanoseconds) for all RAM modules of the same DDR type and frequency in our database. Each bar represents the number of modules that fall within a specific latency range. The highlighted bar indicates the latency of the currently selected RAM module.
