Windows 7: CPU L2 cache not known to win 7

CPU L2 cache not known to win 7

Again, this is another tweak I found in Yamicsoft Windows 7 manager. I have yet to make changes, am just exploring the software.

On the top in this picture, it states that you can manually set file caching memory settings, and below that that it is necessary to manually set the processor L2 cache. Anyone know if this is really the case?

No there is no need for Windows to know about L* cache levels. Only the CPU can make use of those areas. The RAM is what the OS manages, the CPU manages L* caches.

The above settings sets: (It only matters if Windows cannot detect the size automatically.)

The caching that can be managed by the OS is strictly its own caching function, i.e. blocks read form disk, etc. It can also tell a storage controller to set its writeback caching on and off. But as Logicearth stated, CPU caches are managed and used by the CPU itself.

MusicLover7 - This represents a small part of what I was talking about earlier today in another thread.

You are using the right approach though. Investigate what the settings mean. Unless you have a specific need to change one, do not. The default setting is the default for a reason.

For the most part, the default settings are "loose", allowing for the widest range of normal operating conditions (flexibility). Tighten one end of the rope too much, the rope might snap when pulled.

Some of the settings are useless.
