Memory Support and Installation
4.3.2 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.
4.3.3 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.
4.3.4 Introduction to Intel® Optane DC Persistent Memory
Intel® 82xx processor support the Intel Optane™ DC Persistent Memory technology.
Intel Optane DC PMem offers data persistence with higher capacity at lower latencies
than the existing memory modules and provides hyper-speed storage capability for
high
performance computing platforms with flexible configuration options.
4.3.5 Memory Support
Each CPU board supports up to 3 TB DCPMM* or 3DS LRDIMM (Load Reduced)/
LRDIMM/3DS RDIMM (Registered)/RDIMM DDR4 memory of 2933 MHz in 12 DIMM
slots. It also supports up to 4.5 TB Intel Optane DC PMem and DDR4 combined
memory in12 DIMM slots. With eight CPU boards installed, your system will support
up to 24 TB of DDR4 memory or up to 36 TB Intel Optane DC PMem & DDR4
combined memory in 96 memory slots.
