13. Server Board can’t detect a 10Gb IO Module or a QDR IB IO Module

without a PCI Riser installed

Problem When the riser is removed from the server board, the PCI-E lane settings

prevent a x8 PCI-E IO Module (10GbE or QDR IB) from being detected.

Implication Problem is only seen with the x8 PCI-E IO Modules and only when a riser is

removed. This problem does not affect the other IO Modules.

Status This issue may be fixed in a future revision of the server board.

Workaround Be sure that a riser is installed when using the 10GbE or QDR IB IO Modules.

14. Cannot update DVD Drive FW when 6 DIMMs are installed

Problem When all memory channels are populated and active, the FW update for the

SATA DVD drive fails.

Implication System must not have 6 or more DIMMs installed if updating the DVD Drive

FW.

Status This issue may be fixed in a future BIOS revision.

Workaround None

15. Closed Loop Thermal Throttling (CLTT) is not automatically detected

and set when using unbuffered memory (UDIMMs)

Problem When using UDIMMs, CLTT will not automatically be selected if using the

“Auto” feature on the System Acoustics and Performance page of BIOS setup.

Users must ensure that the Serial Presence Detect (SPD) on ALL installed

DIMMs supports CLTT. If the user is unsure if ALL DIMMs installed support

CLTT, then the user should maintain the system in Open Loop Thermal

Throttling (OLTT).

Implication If users elect to utilize UDIMMs in their system, they must manually enable

CLTT in BIOS setup. If the setting is left on “Auto” with UDIMMs installed, the

setting will revert to OLTT.

Status This issue may be fixed in a future BIOS revision.

Workaround None
