Description
NorthBridge Chipset Configuration
Memory CLK
Read only
It shows the clock frequency of the
installed SDRAM.
CAS Latency (Tcl)
Read only
This controls the timing delay (in clock
cycles) before SDRAM starts a read
command after receiving it.
RAS/CAS Delay (Trcd)
Read only
When DRAM is refreshed, both rows
and columns are addressed separately.
This setup item allows you to determine
the timing of the transition from RAS
(row address strobe) to CAS (column
address strobe). The less the clock
cycles, the faster the DRAM
performance.
