Upgrading System Memory; Installing A Memory Module - HP t630 Thin Client Troubleshooting Manual

Upgrading system memory

The memory socket on the system board is populated with one memory module. To achieve the maximum
memory support, you can populate each memory socket with up to 16 GB of memory each (32 GB total).
For proper system operation, the memory module must adhere to the following specifications:
● Industry-standard 260-pin Small Outline DIMM (SODIMM)
● Unbuffered non-ECC PC4-17000 DDR4-1866 MHz
● 1.2 volt DDR4-SDRAM memory module
The thin client supports the following:
● Single-Rank and Dual-Rank modules
● Single-sided and double-sided memory modules
● Strongly recommend using the identical memory (same vendor, die revision and capacity) when using both
SODIMM slots
Higher-speed DDR4 SODIMM modules will actually operate at a maximum system memory speed of 1866 MHz.
NOTE: The system does not operate properly when a nonsupported memory module is installed.

Installing a memory module

CAUTION: You must unplug the power cord and wait approximately 30 seconds for the power to drain before
adding or removing memory modules. Regardless of the power-on state, voltage is always supplied to the
memory modules as long as the thin client is plugged into an active AC outlet. Adding or removing memory
modules while voltage is present may cause irreparable damage to the memory modules or system board.
The memory module socket has gold-plated metal contacts. When upgrading the memory, it is important to use
a memory module with gold-plated metal contacts to prevent corrosion and/or oxidation resulting from having
incompatible metals in contact with each other.
Static electricity can damage the electronic components of the thin client or optional cards. Before beginning the
following procedures, be sure that you are discharged of static electricity by briefly touching a grounded metal
object.
When handling a memory module, be careful not to touch any of the contacts. Doing so may damage the
module.
1. Remove/disengage any security devices that prohibit opening the thin client.
2. Remove all removable media, such as USB flash drives, from the thin client.
3. Turn off the thin client properly through the operating system, and then turn off any external devices.
4. Unplug the power cord from the AC outlet, and disconnect any external devices.

5. Remove the stand from the thin client.
6. Position the unit flat on a stable surface with the right side up.
