[By SPD]
► DRAM Timing Controlled
This item is used to enable/disable provision of DRAM timing by SPD device. The Serial
Presence Detect (SPD) device is a small EEPROM chip, mounted on a memory module. It
contains important information about the module's speed, size, addressing mode and various
other parameters, so that the motherboard memory controller (chipset) can better access the
memory device.
Select [Auto] for SPD enable mode.
Select [Manual] to set the parameters by yourself.
The following 4 settings are valid only when the Memory Timing by SPD is set to [Manual].
► CAS Latency Time (tCL)
This item controls the CAS latency, which determines the timing delay (in clock cycles) before
SDRAM starts a read command after receiving it.
► RAS# to CAS# Delay (tRCD)
This item allows you to select a delay time (in clock cycles) between the CAS and RAS strobe
signals.
► RAS# Precharge (tRP)
This item allows you to select the DRAM RAS precharge time (in clock cycles).
► Precharge Delay (tRAS)
This item allows you to set the precharge delay time (in clock cycles).
► DRAM Frequency
This item is used to adjust the memory speed. Select [Auto] for SPD enable mode. You can
select a value manually suc
h as [800 MHz], [1067 MHz] and [1333MHz]..
► Memory Hole
This item is used to set the memory hole. The available values are [Disabled] and [Enabled].
Some special ISA cards require this area of memory for them to work properly. Enabling this
function reserves the memory area for the card's use. In some cases, it may also prevent the
system from accessing memory above 15MB. If you enable this function, 1MB of RAM (the
