MLC Streamer
Enabled
Disabled
MLC Streamer is a
speculative prefetch unit
within the processor(s)
Note: Modifying this setting
may affect performance.
MLC Streamer is normally
Enabled, for best efficiency in L2
Cache and Memory Channel use,
but disabling it may improve
performance for some processing
loads and on certain benchmarks.
MLC Spatial
Prefetcher
Enabled
Disabled
[Enabled] – Fetches adjacent
cache line (128 bytes) when
required data is not currently
in cache.
[Disabled] – Only fetches
cache line with data required
by the processor (64 bytes).
MLC Spatial Prefetcher is
normally Enabled, for best
efficiency in L2 Cache and
Memory Channel use, but
disabling it may improve
performance for some processing
loads and on certain benchmarks.
DCU Data
Prefetcher
Enabled
Disabled
[Enabled] The next cache line
will be prefetched into L1 data
cache from L2 or system
memory during unused cycles
if it sees that the processor
core has accessed several
bytes sequentially in a cache
line as data.
[Disabled] – Only fetches
cache line with data required
by the processor (64 bytes).
DCU Data Prefetcher is normally
Enabled, for best efficiency in L1
Data Cache and Memory Channel
use, but disabling it may improve
performance for some processing
loads and on certain benchmarks.
DCU Instruction
Prefetcher
Enabled
Disabled
The next cache line will be
prefetched into L1 instruction
cache from L2 or system
memory during unused cycles
if it sees that the processor
core has accessed several
bytes sequentially in a cache
line as data.
DCU Instruction Prefetcher is
normally Enabled, for best
efficiency in L1 I Cache and
Memory Channel use, but
disabling it may improve
performance for some processing
loads and on certain benchmarks.
Direct Cache
Access (DCA)
Enabled
Disabled
Allows processors to increase
the I/O performance by
placing data from I/O devices
directly into the processor
cache.
System performance is usually
best with Direct Cache Access
Enabled. In certain unusual
cases, disabling this may give
improved results.
