commands may be issued in clocks N+1 through N+9. To program this field, BIOS must con-
vert the tFAW parameter into MEMCLK cycles by dividing the highest tFAW (in ns) across all
DIMMs connected to the channel by the lowest period (highest frequency) of MEMCLK (in ns)
over all P-states and rounding up to the next integer.

ECC Configuration

► ECC Mode

This item is used to set the level of the ECC (Error Checking and Correcting) protection. If you
select the ‘Super’ mode, you can dynamically sets the DRAM scrub rate so all of the memory
is scrubbed in 8 hours. When you select the ‘User’, you can enabled or disable the following
items.

► DRAM ECC

It allows hardware to report and correct memory errors automatically maintaining system
integrity.

► DRAM SCRUB REDIRECT

It allows the system to correct DRAM ECC errors immediately, when they occur, even if back-
ground scrubbing is on.

► 4-Bit ECC Mode

It is used to enable or disable 4-BIT ECC Mode.(Note: Also known as CHIPKILL ECC Mode)

► DRAM BG Scrub

This item is used to correct memory errors so later reads are correct. Doing this while memory
is not being used improves performance.(Note: When AMD’s node interleave feature is en-
abled, BIOS will force DRAM scrub off.)

► Data Cache BG Scrub

It allows the L1 Data Cache ram to be corrected while idle.

► L2 Cache BG Scrub

It allows the L2 Data Cache ram to be corrected while idle.

► L3 Cache BG Scrub

It allows the L3 Data Cache ram to be corrected while idle.
