Memory Support for the X11 UP/DP/MP Motherboards
This document provides the user with an easy-to-use guide for proper memory configuration
and installation for the X11 UP/DP/MP (Socket P/Socket P0) Motherboards utilizing
RDIMM/3DS RDIMM/LRDIMM/3DS LRDIMM memory modules. To ensure proper memory
installation, please follow the information and instructions listed below.
1 ESD Precautions
Electrostatic Discharge (ESD) can damage electronic components including memory modules.
To avoid damaging your DIMM modules, it is important to handle it very carefully. The following
measures are generally sufficient to protect your equipment from ESD.
Precautions
•
Use a grounded wrist strap designed to prevent static discharge.
• Handle the memory module by its edges only.
• Put the memory modules into the antistatic bags when not in use.
• Check the Supermicro website for recommended memory modules
2 Memory Support
The X11 UP/DP/MP motherboard supports 3DS LRDIMM (3DS Load Reduced DIMM)/
LRDIMM (Load Reduced DIMM)/3DS RDIMM (3DS Registered DIMM)/RDIMM (Registered
DIMM), DDR4 (288-pin) ECC 2133/2400/2666 MHz memory modules. Refer to the following
tables for detailed information on memory support for the X11 UP/DP/MP motherboards.
DIMM Population Guidelines

3 Memory Installation Sequence
Memory modules for the X11 UP/DP/MP motherboards are populated using the "Fill First"
method. The blue memory slot of each channel is considered the "first DIMM module" of
the channel, and the black slot, the second module of the channel. When installing memory
modules, be sure to populate the blue memory slots first and then populate the black slots.
To maximize memory capacity and performance, please populate all DIMM slots on the
motherboard, including all blue slots and black slots.
4 General Memory Population Requirements
1. Be sure to use the memory modules of the same type and speed on the motherboard.
Mixing of memory modules of different types and speeds is not allowed.
2. Using unbalanced memory topology such as populating two DIMMs in one channel while
populating one DIMM in another channel on the same motherboard will result in reduced
memory performance.

5 DIMM Population Guidelines for Optimal Performance
For optimal memory performance, follow the instructions listed in the tables below when
populating memory modules.
5.1 Key Parameters for DIMM Configuration
Key Parameters for DIMM Configurations
Parameters Possible Values
Number of Channels 1, 2, 3, 4, 5, or 6
Number of DIMMs per Channel 1DPC (1 DIMM Per Channel) or 2DPC (2 DIMMs Per Channel)
DIMM Type RDIMM (w/ECC), 3DS RDIMM, LRDIMM, 3DS LRDIMM
DIMM Construction • non-3DS RDIMM Raw Cards: A/B (2Rx4), C (1Rx4), D (1Rx8), E (2Rx8)
• 3DS RDIMM Raw Cards: A/B (4Rx4)
• non-3DS LRDIMM Raw Cards: D/E (4Rx4)
• 3DS LRDIMM Raw Cards: A/B (8Rx4)
5.2 DIMM Mixing Guidelines
General DIMM Mixing Guidelines
DIMM Mixing Rules
• All DIMMs must be all DDR4 DIMMs.
• x4 and x8 DIMMs can be mixed in the same channel.
• Mixing of LRDIMMs and RDIMMs is not allowed in the same channel, across different
channels, and across different sockets.
• Mixing of non-3DS and 3DS LRDIMM is not allowed in the same channel, across
different channels, and across different sockets.
Mixing of DIMM Types within a Channel
DIMM Types RDIMM LRDIMM 3DS LRDIMM
RDIMM Allowed Not Allowed Not Allowed
LRDIMM Not Allowed Allowed Not Allowed
3DS LRDIMM Not Allowed Not Allowed Allowed
DIMM Population Guidelines
3. Populating memory slots with a pair of DIMM modules of the same type and size will
result in interleaved memory, which will improve memory performance.

5.5 Memory Population Tables for the X11MP Motherboards
For your system memory to work properly, please follow the memory population tables
below to install your memory modules on the X11MP (4-way/8-way) motherboards.
These memory population tables were created based on the general memory popula-
tion guidelines provided by Intel to support Supermicro's X11 Series motherboards.
5.5.1 Memory Population for the 4-way Motherboard w/Half Memory
Configuration Support (X11QPH+ with 24 DIMM Slots Installed)
Note 1: Unbalanced memory configuration decreases memory performance and is not
recommended for Supermicro motherboards.

6 DIMM Installation
1. Follow the instructions given in the
memory population guidelines listed in
the previous sections to install memory
modules on your motherboard. For the
system to work properly, please use
memory modules of the same type and
speed on the motherboard. (See the Note
below.)
2. Push the release tabs outwards on both
ends of the DIMM slot to unlock it.
3. Align the key of the DIMM module with the
receptive point on the memory slot.
4. Align the notches on both ends of the
module against the receptive points on the
ends of the slot.
5. Use two thumbs together to press the
DIMM module straight down into the slot
until the module snaps into place.
6. Press the release tabs to the lock positions
to secure the DIMM module into the slot.
7 DIMM Removal
Reverse the steps above to remove the DIMM
modules from the motherboard.
Release Tabs
Notches
Insert the DIMM module into the memory slot.
