Lenovo ThinkSystem SR665 V3 User Manual page 163

– Never hold two or more memory modules together so that they do not touch each other. Do not stack
memory modules directly on top of each other during storage.
– Never touch the gold memory module connector contacts or allow these contacts to touch the outside
of the memory module connector housing.
– Handle memory modules with care: never bend, twist, or drop a memory module.
– Do not use any metal tools (such as jigs or clamps) to handle the memory modules, because the rigid
metals may damage the memory modules.
– Do not insert memory modules while holding packages or passive components, which can cause
package cracks or detachment of passive components by the high insertion force.
• In the case of processor board replacement, keep records of the slots in which the modules are installed,
and make sure to install them back to the exact same slots after processor board replacement.
• If you are not installing a replacement memory module to the same slot when processors with TDP greater
than 240 W are installed, make sure you have memory module filler available.
