Here are a couple examples:
1. an old Pentium 4 server with two slots, each of which can
hold a 1 GB non-ECC DIMM:
Handle 0x0033, DMI type 16, 15 bytes
Physical Memory Array
Location: System Board Or Motherboard
Use: System Memory
Error Correction Type: None
Maximum Capacity: 2 GB
Error Information Handle: 0x0032
Number Of Devices: 2
2. a semi-old Opteron 250 system with 8 slots, each of which can hold
a 1 GB non-registered ECC DIMM:
Handle 0x0021, DMI type 16, 15 bytes
Physical Memory Array
Location: System Board Or Motherboard
Use: System Memory
Error Correction Type: Single-bit ECC
Maximum Capacity: 8 GB
Error Information Handle: Not Provided
Number Of Devices: 8
3. a new-ish Xeon X3430 system that can handle 16 GB of RAM, but oddly
has just 6 slots. So you can max out the system using 4 slots, each
with a 4 GB registered ECC DIMM.
Handle 0x0019, DMI type 16, 15 bytes
Physical Memory Array
Location: System Board Or Motherboard
Use: System Memory
Error Correction Type: Multi-bit ECC
Maximum Capacity: 16 GB
Error Information Handle: Not Provided
Number Of Devices: 6
