English Memclock index value (Mhz)
Places an artificial memory clock limit on the system.
Memory is prevented from running faster than this frequency.
Ø
The Choice: 100Mhz, 133Mhz, 166Mhz, 200Mhz, 216Mhz,
233Mhz or 250Mhz.
CAS# latency (Tcl)
When synchronous DRAM is installed, the number of clock cycles of CAS
latency depends on the DRAM timing. Don't change this field from the
default value specified by the system designer.
Ø The Choice: 2, 2.5 or 3.
Min RAS# active time (Tras)
Places an artificial memory clock limit on the system.
Memory is prevented from running faster than this frequency.
Ø The Choice: Auto or 5T~15T.
RAS# to CAS# delay (Trcd)
This field lets you insert a timing delay between the CAS and RAS
strobesignals, and you can use it when DRAM is written to , read from, or
refreshed. Faster performance is gained in high speed, more stable perfor-
mance, in low speed..
Ø The Choice: Auto or 2T~7T.
Row precharge Time (Trp)
This field specifies the Row precharge Time. Precharge to Active or
Auto-Refresh of the same bank. Typically 20-24 nsec.
Ø The Choice: Auto or 2T~7T.
1T/2T Memory Timing
This item allows you to set the 1T/2T Memory Timing
Ø The Choice: 1T or 2T.
MTRR mapping mode
This item allows you to set the MTRR mapping mode.
Ø The Choice: Continuous or Discretes.
CPU Spreed Specturm
