I am not new to computer hardware, but am still very green to overclocking (as well as asking for help on a forum), and am having trouble with my new rig's overclocking past 3.2 GHz.
To start out- my rig stats-
CPU- Pentium D 805
Mobo- Intel D975XBX Bad Axe Rev. 304 with core voltage mod
RAM- 2x 1GB G.Skill RAM rated at 667MHz, currently running at about 640MHz, overclocked from 533MHz
Video Card- eVGA 7900GT KO Superclocked
Thermaltake Bigwater SE watercooling for CPU
Now the symptoms- I am using Intel's overclocking suite (Desktop Control Center), and up to 3.2 GHz, no problems occur. IDCC uses a "friendly" interface that just asks the user to choose a percentage they wish to increase the frequency (I don't think they use that word, but that is what it is doing), so this is at the 20% range, which I have been using and has been solid for about two weeks. When trying to up the percentage to 22%, the screen goes black, the speakers make a loud hiss, and the computer restarts. Trying to up the voltage on the CPU or RAM has not changed the situation, and CPU temperature has rarely gone beyond 68C. I know very little about RAM timings and have not messed with them, but know that they are 4-4-4-12 on my rig, if that helps at all. As I am typing this, I am realizing that it could be that the already superclocked video card might be the limiting factor, but would this cause a system reboot? Anywho, I'm at work so I cannot test anything during the day, but any suggestions on a course of action would be greatly appreciated.
