Hi,
I have overclocked my QX6850 to 3.66GHz. Running everest ultimate for stress testing I had found my PC stable with 1.4875v. After stress testing for 8 hours... I thought it was good enough.
Recently I had RMA'd my MOBO (Sriker Extreme) and wanted to re-attempt to lower voltage at least by 1 or 2 notches... I felt it wasn't going to be much different lowering 1 or 2 notches but wanted to retry and get the lowest possible stable voltage... My PC generates too much heat.
So last night I started by lowering voltage by 2 notches and it was stable... and I was like... hmmm, let try lower, so I lowered 4 notches before going to sleep and when I woke up it was still running (7.5 hours).... I was like wow!! I thought... for sure, it's gonna fail if I continue... but for me to check what's the lowest, I've got to continue lowering until it fails... so I lowered another 4 notches and left the stress test running before leaving for work.
OK, so far I have lowered voltage 6 notches and 7C cooler. Still checking how much lower I can go but I called my place and I was told me that it's still running... so stress test has been running for 5 hours and a good possiblity to be stable for 8 hours...
I'm happy to have been able to lower voltage by 6 notches and good possibilty to lower further, but I'm surprised that this was possible by changing MOBO (same model but not sure what BIOS version I had with previous MOBO).
Does anyone have any comment on why I have been able to lower voltage with new MOBO.
Thanks in advance for any comments.
