The Precision 490 can handle up to 32GB of memory in 8 dual in-line memory modules. The 8 memory sockets are split into two sets of four, one for each processor. Each set of four sockets are divided into two channels with two memory slots per channel.
The supported memory DIMM type and size is dependent on your current computer configuration. The Dell Precison 490 uses 2GB, 4GB, 8GB, or 16GB RDIMMs. For best performance, fully buffered DIMMs should be installed in sets of four. Memory frequency is determined by the speed of the DIMMs, speed supported by the processor, and the configuration of the DIMMs. DIMMs must be installed starting with the slot furthest from the processor. Always think long term when upgrading memory.
You can purchase RAM from Dell Spare Parts, or for guaranteed retunable parts try Crucial: http://dell.to/2lkOtuS
