Chapter 2 MS-7760 ▶ tWRDRDD Write-Read Different Ranks same or Different DIMM. ▶ tRWSR Read-Write Same Rank. ▶ Spread Spectrum This function reduces the EMI (Electromagnetic Interference) generated by modulating clock generator pulses. Important • If you do not have any EMI problem, leave the setting at [Disabled] for optimal system stability and performance. But if you are plagued by EMI, select the value of Spread Spectrum for EMI reduction. • The greater the Spread Spectrum value is, the greater the EMI is reduced, and the system will become less stable. For the most suitable Spread Spectrum value, please consult your local EMI regulation. • Remember to disable Spread Spectrum if you are overclocking because even a slight jitter can introduce a temporary boost in clock speed which may just cause your overclocked processor to lock up. ▶ Vdroop Control Load line droop controls the stream of current to the CPU.

tWRDRDD
Wr±te-Read D±fferent Ranks same or D±fferent DIMM.
tRWSR
Read-Wr±te Same Rank.
Spread Spectrum
Th±s funct±on reduces the EMI (Electromagnet±c Interference) generated by modulat±ng
clock generator pulses.
Important
If you do not have any EMI problem, leave the sett±ng at [D±sabled] for opt±mal system
stab±l±ty and performance. But ±f you are plagued by EMI, select the value of Spread
Spectrum for EMI reduct±on.
The greater the Spread Spectrum value ±s, the greater the EMI ±s reduced, and the
system w±ll become less stable. For the most su±table Spread Spectrum value,
please
consult your local EMI regulat±on.
Remember to d±sable Spread Spectrum ±f you are overclock±ng because even a sl±ght
j±tter can ±ntroduce a temporary boost ±n clock speed wh±ch may just cause your
overclocked processor to lock up.
Vdroop Control
Load l±ne droop controls the stream of current to the CPU.
[Auto]
Automat±cally sets values for max±mum stab±l±ty.
[Low VDroop]
Prov±des less fluctuat±on (better for overclock±ng).
