Award BIOS Setup Utility
Manual
If you want better performance for your system
other than the one “by SPD”, select “Manual”
then select the best option in the “CAS Latency
Time” to “DRAM RAS# Precharge” fields.
3.1.3.2 CAS Latency Time
This field is used to select the local memory clock periods.
3.1.3.3 Active to Precharge Delay
The options are 5, 6 and 7.
3.1.3.4 DRAM RAS# to CAS# Delay
The options are 2 and 3.
3.1.3.5 DRAM RAS# Precharge
This field controls RAS# precharge (in local memory clocks).
3.1.3.6 DRAM Data Integrity Mode
The ECC (Error Checking and Correction) function is suppor ted
only in x72 (72-bit) PC SDRAM DIMMs. If you are using x64 (64-
bit) PC SDRAM DIMMs, set this field to Non-ECC.
Non-ECC
Uses x64 PC SDRAM DIMM.
ECC
This option allows the system to recover from
memory failure. It detects single-bit and multiple-bit
errors, then automatically corrects single-bit error.
3.1.3.7 Memory Frequency For
This field is used to select the memory clock speed of the DIMM.
3.1.3.8 DRAM Read Thermal Mgmt
This field is used to detect the DDR’s thermal condition.
