tCL: CAS controls the amount of time between receiving a command and acting on that command.
Typical Settings: 2,2.5,3
Effects: Large Effect on Bandwidth and Stability
NOTE: BH5/BH6 typically will NOT run at anything higher than 2
tRCD: tRCD is the cycle time between the first stage in memory access, the row strobe, and the second stage.
Typical Settings: 2,3,4,5
Effects: Medium Effect on Bandwidth and Large effect on Stability
Her skal det lige siges at det er omvendt. Trcd er væsentligt vigtigere end tcl når det drejer sig om performance.
