tRP
When the DRAM Tmng Mode sets to [Manual], the field s adjustable. Ths settng
controls the number of cycles for Row Address Strobe (RAS) to be allowed to pre-
charge. If nsufficent tme s allowed for the RAS to accumulate ts charge before
DRAM refresh may be ncomplete and DRAM may fal to retan data. Ths tem ap-
ples only when synchronous DRAM s nstalled n the system.
tRAS
When the DRAM Tmng Mode sets to [Manual], the field s adjustable. Ths settng
determnes the tme RAS takes to read from and wrte to a memory cell.
tRTP
When the DRAM Tmng Mode sets to [Manual], the field s adjustable. Ths settng
controls the tme nterval between a read and a precharge command.
tRFC
When the DRAM Tmng Mode sets to [Manual], the field s adjustable. The row cycle
tme determnes the mnmum number of clock cycles a memory row takes to com-
plete a full cycle, from row actvaton up to the prechargng of the actve row.
tWR
When the DRAM Tmng Mode sets to [Manual], the field s adjustable. It specfies
the amount of delay (n clock cycles) that must elapse after the completon of a vald
wrte operaton, before an actve bank can be precharged. Ths delay s requred to
guarantee that data n the wrte buffers can be wrtten to the memory cells before
precharge occurs.
tRRD
When the DRAM Tmng Mode sets to [Manual], the field s adjustable. Specfies the
actve-to-actve delay of dfferent banks.
tWTR
When the DRAM Tmng Mode sets to [Manual], the field s adjustable. Ths tem
controls the Wrte Data In to Read Command Delay memory tmng. Ths consttutes
the mnmum number of clock cycles that must occur between the last vald wrte op-
eraton and the next read command to the same nternal bank of the DDR devce.
FSB/DRAM Rato
Ths tem wll allow you to adjust the rato of FSB to memory.
Adjusted DRAM Frequency (MHz)
It shows the adjusted Memory frequency. Read-only.
Adjust PCI-E Frequency (MHz)
Ths field allows you to select the PCIE frequency (n MHz).
Auto Dsable DRAM/PCI Frequency
When set to [Enabled], the system wll remove (turn off) clocks from empty DIMM and
PCI slots to mnmze the electromagnetc nterference (EMI).
CPU Voltage (V)/ CPU GTL REF (V)/ DRAM Voltage (V)/ DRAM REF (V)/ NB Voltage
(V)/ VTT FSB Voltage (V)
These tems are used to asjust the voltage of CPU, Memory and chpset.
