Intel C602

Dell PowerEdge T620 Server

The Dell PowerEdge T620 is a Tower based server that has the ability to be converted into a rackmount server when a mounting bracket and rails are installed. It features a proprietary Dell motherboard which is run by an Intel C602 series chipset  (Desktop Similar is the X79 Chipset). This allows for dual Sandy Bridge-EP (E5-2600 v1 series) processors or Ivy Bridge EP (E5-2600 v2 series) processors (If BIOS revision 2.0.19 or newer is installed) and 24 slots for DDR3 RDIMMs or LRDIMMs

When running BIOS revision 2.1.2 or newer the maximum addressable memory for a single socket configuration is 768GB with Quad or Octo Rank Load-Reduced DIMMs. With a dual processor configuration, this figure is doubled to 1536GB. This is using 24 of the recently released 64GB LRDIMMs. If using a revision older than 2.1.2 then the maximum addressable will be 384GB in a single socket configuration or 768GB in a dual socket configuration. This is achieved using 24 32GB LRDIMMs. Of note, you cannot utilize 64GB DIMMs until the BIOS is updated and you may not use the memory slots assigned to a non-populated processor. An E5-2600 V2 processor is required to utilize 64GB LRDIMMs. To explain further, you cannot achieve the 768GB single processor maximum by using 24 32GB DIMMs because 12 of the slots are associated with the empty processor socket. The memory can operate at 1333MT/s in all configurations and ranks except for triple channel configurations. With RDIMMs the maximum then becomes 800MT/s in triple channel and LRDIMMs can still operate at 1066MT/s in triple channel

There are many storage configurations for the Dell PowerEdge T630. One option is 32 2.5" drives without the flexbay or 18 2.5" with the flexbay.  Another option is 18 3.5" drives without the flexbay or 8 with the flexbay. The flexbay is essentially a riser card that allows the install of PCIe SSD cards in the front or additional hard drives or solid state drives.
