The 7420 controller supports the following configurations:

  • Two, four, or eight 8GB DDR3 DIMMs installed on each riser, accommodating 128GB, 256GB, or 512GB of memory for 2.0Ghz CPUs.

  • Four or eight 8GB DDR3 DIMMs installed on each riser, accommodating 256GB or 512GB of memory for 2.0GHz and 2.4Ghz CPUs.

  • Four or eight 16GB DDR3 DIMMs installed on each riser, accommodating 512GB or 1TB of memory for 2.4Ghz CPUs.


Note - For proper cooling, memory risers corresponding to unpopulated CPU sockets must have fillers installed.

Previous 7420 controller configurations support two or four (1.86GHz or 2.00GHz) CPUs, with two memory risers required by each CPU. Four or eight 4GB or 8GB DDR3 DIMMs are installed on each riser, accommodating up to 256GB of memory for two CPUs, or up to 512GB for four CPUs.
