Memory Timing Config

► ECC Scrubbing

ECC Scrub is basically ECC with one additional characteristic, it completely refreshes the
memory after each correction. This item is used to enable/disable ECC Scrubbing feature.

► DRAM Timing Selectable

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 DDR3 memory
module. It contains important information about the module's speed, si�e, addressing mode
and various other parameters, so that the motherboard memory controller (chipset) can better
access the memory.

► 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).

► Row Refresh Cycle (tRFC)

This item allows you to set Row Refresh Cycle (in clock cycles).

► Performance Level

This item allows you to set the performance level for your memory.

► Write to Precharge (tWR)

This item allows you to set Write to Precharge delay (in clock cycles).

► Write to Read Delay (tWTR)

This item allows you to set minimum Write-to-read delay (in clock cycles).

► Act to Act Delay (tRRD)

This item allows you to set Act to Act Delay (in clock cycles).
