SUPPLEMENTAL MATERIAL
Recommended Memory Population
This section explains the recommended DIMM population order rules for the C24 M3 server.
All DIMMs must be DDR3 DIMMs.
Mixing of Registered and Unbuffered DIMMs is not allowed per platform.
Mixing of ECC and non-ECC DIMMs is not allowed per platform.
Do not mix 1333-MHz DIMMs with 1600-MHz DIMMs.
Follow Table 23 when populating DIMMs in the server.

Notes . . .
1. For 48 GB, there are two possible sweet spot configurations:
6 x 8 GB occupies 1 DPC, so there is a possibility of increasing total memory size in the system (beyond 48 GB) by
going to 2 DPC while still maintaining memory speed at 1600 MHz.
If there is no plan to increase total memory size in the system (beyond 48 GB), then 12 x 4GB is more price
effective at this time.

2. For 96 GB, there are two possible optimal configurations:
6 x 16GB occupies 1 DPC, so there is a possibility of increasing total memory size in the system (beyond 96 GB) by
going to 2 DPC while maintaining the maximum memory speed at 1600 MHz.
12 x 8GB gives the peak performance for this configuration and is recommended if there is no plan of increasing
the total memory in the future.
