Yep. 7 hours is considered stable and there is no drawback to the lower voltage. I would personally test for 12 hours just to be safe. If you want to use other programs aswell, try OCCT. I think I heard something about "intel burn in test" being good too.
Nonetheless, I think it's safe to say your system is stable. The Athlon II seems to be good with power. I have my quad core overclocked to 3.25GHz and at stock voltage.
Don't forget to test your ram stability too with memtest86 (you can download it online. Burn it to a disk and boot from it to test for 6-8 hours).
Some people might call me too thorough.
Thanks for your reply, I am running memtest86 on my computer now, will give update as soon as I finished the test.
