BIOS.MemSettings.SnoopMode (Read or Write)
Description
Allows tuning of memory performances under different memory bandwidths. The optimal Snoop Mode
setting is highly dependent on workload type. Early Snoop is best used for latency sensitive workloads.
This setting offers the best balance between workload effects. Home Snoop is best used for NUMA
workloads that need maximum local and remote memory bandwidth. Cluster on Die is best used for highly
NUMA optimized workloads. This setting offers the best case local memory latency, but worst case
remote latency. Cluster On Die is only available when Node Interleaving is Disabled. Opportunistic Snoop
Broadcast, available on select processor models, works well for workloads of mixed NUMA optimization. It
offers a good balance of latency and bandwidth.
