Fixes & Enhancements
Fixes
- Issue with MSR 0x1AD which interfered with the new Turbo Ratio Limits has
been fixed, without impacting the factory default settings.
- Added the 'Balanced Memory Mode' option under 'Intel Persistent Memory Performance' in System Profile setting.
- Issue with the memory capacity changing when 'Node Interleaving' or 'Sub NUMA Cluster' is enabled.
- Fixed other miscellaneous issues.
Enhancements
- Updated the 'Processor and Memory Reference Code' for the second-generation
Intel(R) Xeon Processor Scalable Family to IPU 2020.1.
- The S140 firmware is updated to 5.5.2-0006.
- Improved the performance of 4-socket servers by adding 'FastGo' and 'IRQ Throttle' under Processor Settings in System BIOS.
- The memory self-healing feature is added to perform memory
self-healing after an uncorrectable error (MEM 0001) or burst of correctable
errors (MEM 8000). Memory self-healing for a MEM 0001 event will
execute automatically, but for a series of MEM 8000 events, self-healing is
initiated after a system restart.
Important Information
Intel strongly recommends you to not disable the "Monitor/MWait" option on 2-socket servers, because disabling the Monitor/MWait feature is currently not supported for 2-socket PowerEdge servers.
When you try updating a BIOS version either under OS (by using an Update Package (DUP)) or under UEFI Shell (a .efi file), the system may take more time to complete the BIOS update process (in case of a system that has 14 TB memory, it takes around 30 minutes to complete the BIOS update process under Windows Server 2016). There are two ways to work around this issue:
- Use an out-of-band BIOS update method--IDRAC Graphical User Interface (GUI) or RACADM Command Line Interface (CLI) command.
- Physically reduce the memory capacity by removing a few memory modules (and thus improve the speed of the BIOS update process), and then try again.
When you try installing one or more PCIe devices on the system and if the cards require more limited legacy I/O resources, then the system may adjust the legacy I/O resources between the stack and the reboot system automatically. If the system fails during the allocation of PCI resources, then a UEFI0256 error message is logged. You can perform one of the following actions and retry the operation:
- Remove unused PCIe card to free up legacy I/O space.
- Go to System Setup and disable unused PCIe card to free up legacy I/O space.
