Functional Description
3.2.2 RDIMM 1.35 V Configurations
Notes:
1. The Intel Xeon processor 5600 series supports all timings defined by the JEDEC standard.
2. All channels in a system will run at the fastest common frequency.
3. Mixing of registered and unbuffered DIMMs is not supported.
4. If 1.35V and 1.5V DIMMs are mixed, the DIMMs will run at 1.5V.
