is required to guarantee that data in the write buffers can be written to the
memory cells before precharge occurs.
TWTR
W hen the Memory Timings is set to [Manual], the field is adjustable. This item
controls the W rite Data In to Read Command Delay memory timing. This consti-
tutes the minimum number of clock cycles that must occur between the last
valid write operation and the next read command to the same internal bank of
the DDR device.
TREF
W hen the Memory Timings is set to [Manual], the field is adjustable. Specifies

Spread Spectrum
This setting is used to enable or disable the Spread Spectrum feature. W hen
overclocking, always set it to [Disabled].
Important
1. 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.
2. 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.
3. 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.
