Hi. I have mentioned board (for 2 days now) rev. 1.0, bios F3 version, Gigabyte nforce 6600 VGA card, 1 stick Kingmax DDR2 800MHz ram and core 2 duo 6400 cpu. I haven't changed anything in bios (C1, EIST and so on, everything is on default) and managed to reach 396 X 8 (around 3200 MHz) without raising any voltages. Everything works OK, the machine is stable but once in standby STR mode I can't make PC to wake up again (to be more precise - HDDs spin up, fans are working but LCD monitor doesn't start, neither the external USB HDD drive. When I force shutdown by pressing the power-up button, PC tries to power-up by itself over and over again every few seconds so I have to switch of the power-supply button. After that PC boots normally again. I have noticed that standby led diode doesn't flash but I am not shure if this have anything to do with my problem. When not overclocked PC wakes up normally (although a little bit slow when compared to my other platforms) Thanks in advance.
