Low voltage DIMMs require Cisco UCS Manager version 1.2(1) or later, and the related BIOS package.
Only Cisco memory is supported. Third party DIMMs are not tested or supported.
If the system has two CPUs, both CPU DIMM slots should be populated in an identical manner.
The B250 uses Cisco's extended memory technology, where writes happen simultaneously to both
DIMMs in the pair, so they must be identical. Therefore, B250 server memory is always sold as a
correctly matched pair with identical manufacturer, type, speed, and size, intended to be installed
together in the two paired banks of a single UCS Server memory channel. Mixing of unpaired
DIMMs (even with other DIMMs sold under the same product ID) will result in a memory errors
should a mismatch occur. When installing DIMMs in a B250, you must add matched pairs to the
channel slots in the order shown in
a channel, or a configuration of 6 DIMMs per channel.
Carefully match CPU and DIMM speed. If the CPU and DIMM speeds do not match, the system
runs at the slower of the two speeds.
