+The Bonobo WS 16 supports up to 192GB (4x48GB) of DDR5 SO-DIMMs running in dual-channel configuration. The RAM speed depends on the rank and number of SO-DIMMs:
+
+- Any number of single-rank SO-DIMMs will run at a speed of 4400MHz.
+    - The 2x16GB (32GB total) factory configuration runs at this speed.
+- A single dual-rank SO-DIMM will run at 4400MHz.
+    - This configuration is not recommended because running in single-channel mode will result in lower performance than the equivalent capacity running in dual-channel mode at a slightly lower speed.
+- More than one dual-rank SO-DIMM will run at 4000MHz.
+    - All other factory configurations run at this speed.
