tRCD

When DRAM s refreshed, both rows and columns are addressed separately. Ths

setup tem allows you to determne the tmng of the transton from RAS (row ad

dress strobe) to CAS (column address strobe). The less the clock cycles, the faster

the DRAM performance.

tRP

Ths settng controls the number of cycles for Row Address Strobe (RAS) to be

allowed to precharge. If nsucent tme s allowed for the RAS to accumulate ts

charge before DRAM refresh, refreshng may be ncomplete and DRAM may fal

to retan data. Ths tem apples only when synchronous DRAM s nstalled n the

system.

tRAS

Ths settng determnes the tme RAS takes to read from and wrte to memory cell.

tRFC

Ths settng determnes the tme RFC takes to read from and wrte to a memory

cell.

tWR

Mnmum tme nterval between end of wrte data burst and the start of a precharge

command. Allows sense amplers to restore data to cells.

tWTR

Mnmum tme nterval between the end of wrte data burst and the start of a col

umn-read command. It allows I/O gatng to overdrve sense amplers before read

command starts.

tRRD

Speces the actve-to-actve delay of derent banks.

tRTP

Tme nterval between a read and a precharge command.

tFAW

Ths tem s used to set the tFAW (four actvate wndow delay) tmng.

tWCL

Ths tem s used to set the tWCL (Wrte CAS Latency) tmng.

tCKE

Ths tem s used to set the tCKE tmng.

tRTL

Ths tem s used to set the tRTL tmng.

Advanced Channel 1/ 2 Tmng Conguraton

Press <Enter> to enter the sub-menu. And you can set the advanced memory tmng

for each channel.
