Memory Timings: 

Five options are available: Optimal 

 Aggressive  Turbo  By SPD  Expert. The default setting is 

Optimal. Choose Optimal for better memory compatibility; choose Aggressive/Turbo for better memory 
performance; choose Expert for user-define. When set to By SPD, the BIOS will read the DRAM module 
SPD data and automatically set to the values stored in it. 

  Row-active delay: 

Fifteen options are available: from 1 to 15. This option specifies the row active time. This is the minimum 
number of cycles between an activate command and a precharge command to the same bank. 

  RAS-to-CAS delay: 

Seven options are available: from 1 to 7. This item is to set SDR/DDR SDRAM RAS to CAS delay. It 
can define the SDRAM ACT to Read/Write command period. 

  Row-precharge delay: 

Seven options are available: from 1 to 7. This item controls the idle clocks after issuing a precharge 
command to the DRAM. 

  CAS Latency Time: 

Three options are available: 2.0 

 2.5  3.0. The default setting is 2.5. You can select SDRAM CAS 

(Column Address Strobe) latency time according your SDRAM specification. 

System BIOS Cacheable: 

Two options are available: Disabled or Enabled. The default setting is Enabled. When you select Enabled, 
you get faster system BIOS executing speed via the L2 cache. 

Video RAM Cacheable: 

Two options are available: Disabled or Enabled. The default setting is Enabled. When you select Enabled, 
you get faster video RAM executing speed via the L2 cache. You must check your VGA adapter manual 
to find out if any compatibility problems will occur.
