Hi ajimi, you need to give us more information. What RAM do you have? brand, speed, latencies etc...
Dual channel memory technology effectively doubles your memory bandwidth by providing 2 individual 64-bit channels that allow a total of 128-bits to be read or written from the memory bus per CPU clock cycle. For this reason dual channel memory configurations will provide increased performance over single channel configurations.
To achieve optimal Dual Channel mode, the following conditions should be met:
1. Same DRAM DIMM Speeds (PC3200, PC2700, PC2100)*
2. Same Density (128MB, 256MB, 512MB, etc.)
3. Same DRAM DIMM latencies e.g. 3-3-3-8 matched to 3-3-3-8
4. Same DRAM bus width (x8 or x16)
5. All DIMM pairs must be either both single-sided or both dual-sided
6. Matched DIMMS in both Channel A and Channel B memory channels when using 4 DIMMS.
7. Populate correct memory slots (Both blue, both black)
*Memory channel speed is determined by the slowest DIMM module populated in the system.
Note: Configurations that do not match the above conditions may revert to single channel mode.
The following conditions do not need to be met BUT will most likely effect performance:
1. Same brand
2. Same timing specifications (particularly if you use Serial Presence Detect)
3. Same DDR speed
Hope that helps
