HP EliteOne 800 G1 Maintenance & Service Manual page 62

In addition, the computer supports:
1-Gbit, 2-Gbit, and 4-Gbit non-ECC memory technologies
●
single-sided and double-sided SODIMMS
●
SODIMMs constructed with x8 and x16 SDRAMs; SODIMMs constructed with x4 SDRAMs are not
●
supported
NOTE: The system will not operate properly if you install unsupported SODIMM memory.
HP offers upgrade memory for this computer and advises that the consumer purchase it to avoid
compatibility issues with unsupported third-party memory.

The system will operate in single channel mode if the SODIMM sockets are populated in one
●
channel only.
The system will operate in flex mode if the memory capacity of the SODIMM in Channel A is not
●
equal to the memory capacity of the SODIMM in Channel B. In flex mode, the channel populated
with the least amount of memory describes the total amount of memory assigned to dual channel
and the remainder is assigned to single channel. If one channel will have more memory than the
other, the larger amount should be assigned to channel A.
The system will operate in a higher-performing dual channel mode if the memory capacity of the
●
SODIMM in Channel A is equal to the memory capacity of the SODIMM in Channel B.
In any mode, the maximum operational speed is determined by the slowest SODIMM in the
●
system.
There are two memory sockets on the system board located behind the memory access panel. To
remove or install memory modules:
