Chapter 3: Maintenance and Component Installation
Removing a Heatsink
We do not recommend removing the heatsink. If necessary, please follow the instructions
below to prevent damage to the CPU or the CPU socket.
1. Unscrew and remove the heatsink screws from the motherboard in the sequence as
shown in the figure above.
2. Hold and gently pivot the heatsink back and forth to loosen it from the CPU. (Do not use
excessive force when dislodging the heatsink!)
3. Once the heatsink is loose, remove it from the CPU.
4. Clean the surface of the CPU and the heatsink to get rid of the old thermal grease.
Reapply the proper amount of thermal grease to the surface before you re-install the
heatsink.
Memory Installation
Memory Support
The X11SSE-F supports up to 64GB of ECC DDR4-2133/1866/1600/1333 unbuffered
(UDIMM) memory in four memory slots. Populating two adjacent slots at a time with memory
modules of the same size and type will result in interleaved (128-bit) memory, which is faster
than non-interleaved (64-bit) memory.
Check the Supermicro website for possible updates to memory support.
DIMM Module Population Configuration
For optimal memory performance, follow the table below when populating memory.
