In such a case, the reason may be that the Power Regulator value in RBSU (ROM Based Setup Utility) is set to HP Dynamic. The following HP document may be useful: On page 3: 'HP Dynamic Control of P-states resides with the firmware. This mode allows the firmware to change the Pstate of the processor to match the server load. It is the default mode on HP ProLiant G5 and later servers.'

Changing the Power Regulator BIOS setting to 'OS Control', will allow a driver to be loaded. For instance the powernow-k8 will load as the P-state driver on AMD-based ProLiant servers (such as the BL685c G7).

Known Issues:None (8 Oct 2015). Upgrade Requirement: Optional - Users should update to this version if their system is affected by one of the documented fixes or if there is a desire to utilize any of the enhanced functionality provided by this version. Important Notes: Ver. 2014.09.03 (C) contains updates to the component packaging and is functionally equivalent to ver.

It is not necessary to upgrade with Revision C if a previous component Revision was used to upgrade the system ROM to version 2014.09.03. Firmware Dependencies: None Problems Fixed: Resolved an issue where VMware may stop responding and display a Purple Screen with the message 'Exception 14: Page Fault' when running on AMD Opteron 6300 series processors. Known Issues: None. Added a new ROM-Based Setup Utility (RBSU) option 'Memory Proximity Reporting for I/O' that, when enabled, reports the proximity relationship between I/O devices and system memory to the operating system. Most operating systems can use this information to efficiently assign memory resources for devices such as network controllers and storage devices for improved performance. Certain I/O devices might not be able to take advantage of I/O handling benefits if their OS drivers are not properly optimized to support this feature.

Please consult operating system and I/O device documentation for additional details. This option is disabled by default. This option is found in 'Advanced Performance Tuning Options' under 'Advanced Options'. (6 Oct 2014).

Upgrade Requirement: Optional - Users should update to this version if their system is affected by one of the documented fixes or if there is a desire to utilize any of the enhanced functionality provided by this version. Important Notes:None Firmware Dependencies:None Problems Fixed:Resolved an issue with the ROM-Based Setup Utility (RBSU) 'Processor Core Disable (AMD Core Select)' Option. The revision of the System ROM might cause some Operating Systems to report the incorrect number of cores when the 'Processor Core Disable (AMD Core Select)' is set to non-default values. This issue did not impact any other revisions of the System ROM. Known Issues:None (19 Feb 2014). Upgrade Requirement: Optional - Users should update to this version if their system is affected by one of the documented fixes or if there is a desire to utilize any of the enhanced functionality provided by this version.

Important Notes:None Firmware Dependencies:None Problems Fixed:Resolved a rare issue that could result in DIMMs not initializing properly when using RDIMMs or LRDIMMs (UDIMMs are not affected). When this issue occurs, the server may stop responding during system boot or boot with less than the expected amount of memory available to the operating system. If this issue occurs with previous revisions of the System ROM, the System ROM should be updated to this revision or later before replacing DIMMs. Known Issues:None. Added the latest product names of optional expansion cards and updated language translations (for non-English modes) in the ROM-Based Setup Utility (RBSU).

Added support for Single Root I/O Virtualization (SR-IOV). SR-IOV can provide performance benefits in virtualized environments if the Operating System/hypervisor and installed I/O card support SR-IOV. This functionality is enabled via a ROM-Based Setup Utility (RBSU) Advanced System ROM Option. It is disabled by default. When enabled, the System ROM will configure devices that support SR-IOV for use under a supported Operating System. Please consult the proper Operating System and Network Adapter documentation for a list of supported configurations.

(13 Mar 2013). Upgrade Requirement: Recommended - HP recommends users update to this version at their earliest convenience. Important Notes: None Firmware Dependencies: None Fixes: Resolved an issue where enabling AMD I/O Virtualization Technology (AMD-Vi) also known as IOMMU might cause operating systems to boot incorrectly.

This resolves an issue where the BIOS was not correctly configuring the system when the ROM-Based Setup Utility (RBSU) option for AMD Vi was enabled. Resolved an issue where systems with AMD Opteron 6200 series processors running VMWare ESXi 5.0 or other Operating Systems might randomly experience kernel panics (Purple Screen indicating CPU x tried to re-acquire lock) under moderate to heavy network stress between VMs. Known Issues: None (4 Jan 2013).

Upgrade Requirement: Recommended - HP recommends users update to this version at their earliest convenience. Important Notes: None Firmware Dependencies: None Problems Fixed: Resolved an issue that could result in a server reset or the inability to boot. Servers should be updated to this revision of the system ROM to minimize the potential for a system reset or the inability to boot. Resolved an issue where industry standard tools, operating systems, and HP utilities may report less Level 3 (L3) cache than expected. Resolved an issue that can result in significantly increased boot times and potentially degraded performance in an OS environment when 1 Terabyte (TB) of memory is installed and the One Terabyte Memory Limit option is configured to Enable All Memory in the ROM-Based Setup Utility (RBSU). This issue was a result of improperly configuring processor cache settings.

This issue does not exist with any other memory configurations. Resolved an issue where the system may halt during boot when the HPC Optimization Option is enabled and the Power Profile mode is set to Maximum Performance or Custom. The halt may occur when the Power Profile is set to Custom with the Minimum Processor Idle Power State set to No C-states, and the HP Power Regulator is set to either HP Dynamic Power Savings Mode, HP Static Low Power Mode, or HP Static High Performance Mode. Resolved a rare issue where the system and IML may indicate an uncorrectable reset when upgrading to the 8/15/2012 system ROM. Known Issues: None.
