3.3.3 Memory
The CB1050 is equipped with two DIMM184 sockets for DDR-333-RAM. For technical and mechanical
reasons it is possible that particular memory modules cannot be employed. Please ask your distributor for
recommended memory modules
With currently available memory modules a memory extension up to 2 GByte is possible.
All timing parameters for different memory modules are automatically set by BIOS.
N
OTE
For higher security demands DIMM184 modules with ECC parity checking are available. The BIOS will use
this option automatically, though it can be manually disabled in setup. You may notice a performance
decrease with ECC enabled, when using higher video resolutions.
