Help OC Phenom 965BE
Hey everyone, I've been searching online to understand why my Phenom II 965BE can't be overclocked, even at 3.8Ghz with high settings. It's not stable, and the temperatures are low—28°C idle, 48°C under load. The CPU voltage is 1.5v, frequency is 2600Mhz, voltage is 1.2v, and the rest of my setup includes an Asrock 980de3/u3s3 Rev 2.03, OCZ Fatality 550w 80+, and two 4Gb Crucial Ballistix DDR3 at 1600Mhz. Please let me know what I might be missing. Thanks!

I set everything to the default and restarted, moved up to 3.9Ghz with a voltage of 1.52 (max temperature 52°C) and it seems stable after 30 minutes with OCCT. It doesn’t reach that sweet spot of 4Ghz even at 1.55, is there any way to reach it? You might be at the limit of your silicone or board. I wouldn’t push the board too hard if you want it to last. Perhaps you don’t need the same stability as OCCT achieved. My OC boards have always worked well after default settings using Intel Burn Test:

If you can hit 4GHz with the default in IBT, you won’t run into issues during real-time gaming. I haven’t experienced that.
Btw, 1.55v is quite high for that board...
It might be because you're adding too many parameters at once. The board you're using could also be a poor OC'er. It seems like a 4+1 phase design with no heat sinks on the VRMs. Try resetting everything to defaults and gradually increasing the multiplier one step at a time to identify instability. Then adjust the core voltage by 0.005v incrementally until stability returns. Observe how far you can go before issues arise. Mine reached 4.0 GHz with just a slight change in core voltage. That’s likely the maximum for most 965BEs. What method are you using to test stability?

Also, 1.55v is quite high for that board; I’d suggest lowering it to 1.5v or less. In fact, 1.5v is the recommended maximum for the 965BE according to AMD.
It's stable at 3.8Ghz with a vcore of 1.48v, so yes, it's feasible to push beyond that via the NB and/or RAM.
Adjust your memory speed manually to 1333mhz and apply the 9,9,9,24 command at a 2T rate with 1.50v slot voltage. Running at 1600mhz is considered overclocking the 965BEs memory controller, which isn't an issue when using the standard CPU speed.
