Memory Support

The C7Z87-OCE supp orts up t o 32GB of Unbuffered (U DIMM) DDR3 Non-ECC
1600/1333/1066 MHz in 4 memory slots. Po pulating these DIMM modules with a
pair of memory modules of the same ty pe and same size will result in interleaved
memory, which will improve memory per formance. Please refer to th e table below:

Memory Population Guidelines

Please follow the table below when populating the C7Z87.

Notes
•Be sure to use memory modules of the same t ype, same speed, same
frequency on the same motherboard. M ixing of memory modules of dif-
ferent types and speeds is not allowed.
•Due to memory allocation to system devic es, the amount of memory that
remains available for operational use will b e reduced when 4 GB of RAM
is used. The reduction in memory availa bility is disproportional. See the
following table for details.
