L1 Data Cache Context Mode

Common Options : Adaptive, Shared

Quick Review

This BIOS feature allows you to modify the operating mode of the processor's L1 data cache. The L1 data cache can either function in an Adaptive mode or a Shared mode.

When set to Adaptive, data in the L1 data cache is shared by all logical processors. Each logical processor gains access to the full L1 data cache. However, data in the cache may be discarded by any logical processor. This may reduce the performance of one logical processor, to the benefit of the other logical processor.

When set to Shared, the L1 data cache is competitively shared between the logical processors. Each logical processor gets an exclusive part of the L1 data cache. The size of each logical processor's share of the L1 data cache will vary according to the need of each processor.

By default, this BIOS feature is set to Adaptive. However, it is recommended that you set it to Shared for better cache management, and consequently better performance.
