Memory
The CP307 supports a dual-channel DDR2 memory without Error Checking and Correcting
(ECC) running at 667 MHz (PC2-5300-CL5). Channel A is soldered. Channel B provides one
200-pin SODIMM socket for a DDR2 SODIMM module. The maximum memory size per chan-
nel is 2 GB. The available memory module configuration can be either 512 MB, 1 GB, 2 GB, or
4 GB. However, due to internal memory allocations, the amount of memory available to appli-
cations is less than the total physical memory in the system. For example, the chipset’s Dynam-
ic Video Memory Technology (DVMT 3.0) dynamically allocates the proper amount of system
memory required by the operating system and the application.
