okay this is about my brother's PC.He initially bought the PC with 1 GB of DDR2 667 MHz RAM (Transcend Jetram) and today I bought him another RAM stick,a 1 GB RAM module DDR2 of the same frequency but different brand(Dynet).will that hurt performance or hamper the uh "dual channel effect" ? BTW,I installed PC Wizard('05 version) and it's showing the frequency to be of 166 Mhz no matter whether I am using one or both of the modules.

Dual Channel may work with different RAM sticks, but it is less likely. If Dual Channel works there should be a message about this during startup.
As for the frequency, you can try to change it in BIOS.
PC config: Intel Dual Core Pentium E2180 2.0 GHz 1GB Transcend JetRAM 1 GB Dynet RAM both of 667 MHz frequency Mobo:Asus P5GC-MX/1333 Intel 945GC chipset BIOS:AMIBIOS American Megatrends, Inc.
BTW what kind of a message should show if dual channel was activated?
you can check with THIS to make sure you have dual channel enabled/ what speed its actually running at.
If they are both able to run at 667Mhz you should be able to dual channel at that speed if you have dual channel enabled. A couple things that could get in the way though are the default voltages and timings of each module, which may be slightly different.
Modules in dual channel kits are tested to within very tight frequency tolerances of one another and matched in timing and voltage, as well as guaranteed to work at a specified timing and frequency.
In other words, though you can probably get them to run in dual channel at that frequency, you may have to use slightly slower timings if one is lesser than the other in latency. Lesser/slower means higher numbers in the timings btw, because it refers to how many CPU cycles it takes for the RAM to transfer data with the memory controller.
