Caveats
■ If memory PID UCS-ML-2X648RY-E (2x64 GB) is selected, then no GPU option can be selected.
■ NVIDIA GRID K1 and K2 GPUs can be mixed. No other GPU mixing is allowed.
■ If the NVIDIA GRID K1, NVDIA K2, or NVIDIA K40 GPUs are selected:
— Memory option PID UCS-MR-2X162RY-E (2x16 GB) cannot exceed a quantity of 32.
— Memory option PID UCS-ML-2X324RY-E (2x32 GB) cannot exceed a quantity of 16.
■ You must order one power cable for each GPU you order. The power cable plugs into the
motherboard GPU power connector and to the appropriate GPU(s).
■ Slot 7 is the preferred slot for the first GPU.
■ You cannot have a GPU installed in slot 7 and at the same time have a QLE2562 HBA
(N2XX-AQPCI05) installed in slot 9.
■ If any GPU is installed, the maximum amount of DIMM memory allowed in the server is 1 TB
(for example, 32x32 GB DIMMs or 64x16 GB DIMMs).
■ Systems with 64 GB DIMMs cannot implement any GPUs.
