Asrock 970 extreme 3 phenom 2 x4 965 not stable at stock settings.So I can use processor only at 2.5 Gb to be stable,I have reased the voltage from 1.4 to 1.5 and undercooked processor to 3.0 Gh....now looks stable. If I try to use stock settings in bios I can't even boot the pc(win7 64 bit)

Question from popovici_ionrazvan : "PC not stable"

My pc don't want to stay stable at stock settings in bios (assrock pro extreme 3 with phenom 2 x4 965 be 8 gb ddr3 )so i have to decrease the speed of the processor to 2.5 ghz to use it without problems. Today I increased the voltage at 1.5 volts instead of 1.4(which was the stock voltage) and also I increased the frequency to 3.0 ghz. System runs well but I wonder can I raise the frequency to 3.4gb which is the stock frequency at this motherboard. Maybe does anyone know some good settings cause the stock settings don't work.i have updated also the bios to the latest version.

if you download Intel's XTU utility (Extreme Tuning Utility), install it - you can then run a benchmark test. Once it's completed, XTU will ask you if you'd like to upload your score to HWBOT to compare to others on the internet. Select that - once there, clik on the "Analyze" icon, it'll take you to a page with a graph with a number of dots, and an arrow pointing to your "dot". Above the graph clik on the icon listing your cpu and then on the one listing your chipset. It will then only display scores from users runnng your cpu and and the same chipset.

If you hover your cursor over the other dots on the graph, it will display the user's benchmark, clock speed achieved, and the percentage compatible with your system. Scores that show 92% or more compatible, clik on that "dot" and it will display that user's settings on the right hand column. You can choose to download those settings to your desktop - be sure to label them.

Once on your desktop, open XTU and on the left go to "Profiles" - in that, in the upper right hand corner of the main window there's an icon to "import profile" - clik on it, browse to the settings profile you downloaded, import it, then once in the list of profiles clik on it, then up above you'll see a button "show values", clik on that and it will show them in the right hand column. If will show the new values in the column to the right, with the current settings on the left. The new settings that are different will be highlighted in yellow.

You can hit apply, to try those settings - right there in XTU is a stress test - you can watch core temps, voltages etc while the stress test is running

but basically that's the Fred Flintstone approach to OCing. In this case you're just looking for the values that work on your mobo

fwiw
