hi I've just upgraded my ram but i brought 1gb kingston value ram with 6-6-6-18 timings and my other 2 rams are gskill 2*1gb with 5-5-5-15 timings. my concern is will this kingston lower the gskill performace? because my motherboard displays ddr2 667 speed.... but all my rams are 800 mhz.... thanks

Yes becasue it forces all modules to run at a lower speed. Remove the Kingston module to see if it makes a performance difference. If your system requires more than 2GB of RAM, then the lower memory speed still is better than having only 2GB of RAM.
