Snoop Filters and the Tyan S5397

by dave on September 26, 2008

Just to add to the ever-growing information data base on the excellent Tyan S5397.

If you seem to be having problems with reported memory bandwidth in your favourite worthless synthetic benchmark or reality-based simulation workload, try disabling the Snoop Filter in the bios.

Remember, the Intel Xeon processors use a different set of prefetch schedulers than standard “consumer” level parts, so, this can also affect workload.
