3200MT/s DIMM Support for PowerEdge Servers
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:
1. 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.
2. 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.
3. 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
1. 3200MT/s DIMMs are backwards compatible and will automatically
downshift to any memory speed to match the capability of the CPU
2. 3200MT/s DIMMs can be mixed with slower DIMMs and will
automatically downshift and match the speed of the slower DIMM
3. 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
4. All BIOS/iDRAC releases for the supported platforms will support the
3200MT/s DIMMs. *Note firmware is not associated with DIMMs
5. 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
Support for 3200MT/s DIMMS are provided in the tables below:

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.
