Summary
For many years 2666MT/s and 2933MT/s were the standard speeds of memory modules used within servers. Now that 3200MT/s SKUs are ready for public consumption, data center customers have been eager to understand what this transition will look like. This DfD will outline how 3200MT/s DIMMs were validated, what to expect when transitioning them into a new or existing data center, and DIMM/platform support tables.
Validation Process
The Dell Technologies engineering team validated 3200MT/s DIMMs to ensure they performed properly on current-gen platforms, while also integrating seamlessly and without impact to legacy platforms. This 3-step validation process can be seen below:
- Margin Testing - Validation that the transactions routing across the CPU, DRAM, motherboard and BIOS have sufficient margins to ensure a robust signal integrity for reads and writes.
- Mixed Testing - Functional testing is performed to ensure various qualified DIMM vendors, capacities and speeds are operable and compatible with one another within a system.
- Full Functional Testing - Memory stress tests are performed using various industry standard applications, as well as Dell proprietary tests, to ensure DIMM quality is intact for typical user configurations.
What to Expect Upon Transitioning
- 3200MT/s DIMMs are backwards compatible and will automatically downshift to any memory speed to match the capability of the CPU
- 3200MT/s DIMMs can be mixed with slower DIMMs and will automatically downshift and match the speed of the slower DIMM
- 3200MT/s DIMMs are exact replacements in that they have the same capacity, the same number of ranks, the same data width, and the same density as the DIMMs they are replacing
- All BIOS/iDRAC releases for the supported platforms will support the 3200MT/s DIMMs. *Note firmware is not associated with DIMMs
- Dell Technologies support services replaces parts with like or better and they may replace the older 2933MT/S and 2666MT/s parts with the newer 3200MT/s parts since they are backwards compatible
