NOTE:STD and HPR fans support DIMM capacity of less than or equal to 64 GB. Memory capacity of greater than/equal to 96 GB or less than/equal to 128 GB is supported by HPR fan only.
NOTE:*HPRx7 counts are only for with TBU configuration. System without TBU configuration does not support HPRx7 counts.
NOTE:**HPRx7 with TBU configuration:
Riser 1 does not support GPU >75W. GPU <75W support Nvidia A2 and does not support Nvidia L4..
Riser 2 GPU <75 W supports Nvidia A2 and Nvidia L4. For GPU >150 W supports Nvidia A30 (165 W) only.
Fan redundance is not supported with riser installed.
NOTE:***HPRx7 with TBU configuration supports fan redundancy when GPUs <75W are installed on PCIe slot 3,4,5,6.
