Level 2 Cache Latency

Common Options : Auto, 1 to 15

Quick Review

This BIOS feature enables you to change the latency of the processor's Level 2 cache. By default, this feature is set to Auto which means that the processor's Level 2 cache will be left to its default latency setting. This is the safest option.

You can also manually select the latency of the cache. For this purpose, this BIOS feature provides options ranging from 1 clock cycle to 15 clock cycles. Please note that setting too low a latency can cause the Level 2 cache to lose data integrity or fail altogether. This will manifest as a system crash or an inability to boot-up at all.

Therefore, it is recommended that you start with a high latency and work your way down until you start to encounter stability issues. This allows you to figure out the lowest latency your processor's Level 2 cache can support. Select that latency for optimal performance without stability issues.

Please note that this is a processor-dependent feature. Not all processors support BIOS manipulation of the Level 2 cache latency. If the processor does not allow any manipulation of its Level 2 cache latency, this BIOS feature will not have any effect, irrespective of what was selected.
