Advantech ASMB-813I User Manual

ASMB-813I User Manual 50
Note! 1. Intel® recommends exposing all 3 snoop modes as BIOS options
to the user due to the varying memory latency & bandwidth trade
offs across SKUs for each snoop mode.
a). Intel® Xeon® Processor E5-2600 v3 Product Family supports
up to 3 different snoop modes (Early Snoop, Home Snoop, Cluster
on Die) to maintain memory coherency across the 2 sockets.
b). Choosing the optimal snoop mode setting is dependent on the
workload characteristics and the SKU that is used.
2. It is expected behavior for LCC SKUs (4-8 cores) in NUMA & Early
Snoop mode to have low remote bandwidth.
a). For workloads on LCC SKUs that need high local & remote
memory bandwidth, use NUMA & Home Snoop mode at the
expense of higher memory latency (up to 1.07x).
b). For workloads on LCC SKUs that have mostly remote memory
accesses, use UMA & either Early Snoop or Home Snoop mode.
