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. (read only)
Current TRP
This setting controls the number of cycles for Row Address Strobe (RAS)
to be allowed to precharge. If insufficient time is allowed for the RAS to
accumulate its charge before DRAM refresh, refresh may be incomplete
and DRAM may fail to retain data. This item applies only when synchro-
nous DRAM is installed in the system. (read only)
Current TRAS
This setting determines the time RAS takes to read from and write to a
memory cell. (read only)
DRAM Timing
Selects whether DRAM timing is controlled by the SPD (Serial Presence
Detect) EEPROM on the DRAM module. Setting to [By SPD] enables
DRAM timings to be determined by BIOS based on the configurations on
the SPD. Selecting [Manual] allows users to configure the DRAM tim-
ings manually.
CAS Latency
This controls the timing delay (in clock cycles) before SDRAM starts a
read command after receiving it. Settings: [2], [2.5], [3] (clocks). [2]
(clocks) increases the system performance the most while [3] (clocks)
provides the most stable performance.
TRCD
When DRAM is refreshed, both rows and columns are addressed
separately. This setup item allows you to determine the timing of the
