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).

Frequency (MT/s)

667 800
5 14.99 12.50
6 17.99 15.00
CAS (clock cycles) Lower latency means faster memory.

Cheapest alternatives with equal or better performance

-2.50ns Latency
