Hi,
How can I disable HP Memory Pre-Failure Notification on the m510 machines? It's generating 8 SMI (Service Management Interrupt) per second to each core. And each SMI takes >100us. I tried to follow the instructions documented in the HP technical whitepaper "Configuring and tuning HPE ProLiant Servers for low-latency applications" but the RBSU menu on m510 is different. Specifically, I cannot find the "Service Options". Here are some screenshots of what I am looking for: http://serverfault.com/a/508873.
Thanks!

Sorry this has taken so long. I haven't been able to discover anything yet
in the Moonshot x86 BIOS to address this. We will ask our contacts at HP.
Do you have a simple benchmark to demonstrate this? I.e., so that if I find
some promising option, I can test whether it has any effect.

Thanks for looking into this. To see the number of SMI per second, simply run `sudo turbostat --debug --interval 1` and look for the SMI column. Right now, this number should be 8.
