Subject: [PATCH 3/6] Tweak cmos defaults for KCMA-D8 (for a little speed
|
|
boost)
|
|
|
|
63xx CPUs have the option to use a reduced latency value inside the crossbar.
|
|
Setting "experimental_memory_speed_boost=Enable" aparently only has an effect
|
|
on 63xx CPUs and may, in certain cases, yield a slight memory bandwidth
|
|
increase (according to Timothy Pearson), but maybe it also works for
|
|
43xx CPUs.
|
|
|
|
Setting "l3_cache_partitioning=Enable" will increase performance in certain
|
|
situations. See:
