I initially had a system with 2 gb RAM (2 X 1gb) and I bought an additional 1 stick of 2gb RAM recently but my system fail to work after installing it, it reboots by itelf after 1 to 2 mins of operation and the fonts were terribly big which indicates that something isn't right, but if I remove one of the 1gb RAM which leaves 3gb RAM (1 stick of 1gb RAM in one channel and a 2gb on another), it will work. Anyone can advice what could be the problem?

I am using a Biostar TA690G AM2 board and Kingston DDR2 KVR667D2N5 RAMS.

Thanks!

Get another stick of ram the memory slots are ganged as in 1-3 and 2-4,sticks of ram must be in pairs , except maybe the 1st slot, some mobo's allow single stick in that slot and only as single stick as in 64 bit instead of ddr2 128 bit that we get with 2x dd2.same protocol applies to dd3..:)
