Phenom ll x4 965 Black Edition
Hello,
I've checked the search bar multiple times, but this issue has been discussed many times before. Still, it's important to stay cautious with costly computer components.
Relevant specifications:
Mobo: GIGABYTE GA-970A-UD3P (rev. 2.0)
Heatsink: Hyper Evo 212
I adjusted the CPU multiplier to 18 instead of 17 and kept the voltage at the default 1.475v. The overclock appears stable after a stress test, with maximum CPU temps around 54°C and voltage at 1.476v. I attempted to increase it further to 19 MHz and raise the voltage by 0.01, but this caused the system to crash during the test. After resetting back to the stable setting, performance returned to normal, though reaching 3.8GHz remains a challenge (currently at 3.6GHz).
Thanks.
I'm not entirely confident about the 965, but my 955 achieves a fairly stable OC at 3.8 1.6v. Your machine's maximum temperatures are around 65°C, so you might try increasing the voltage to 1.5 and observe the results. You'll likely need powerful cooling to handle those recommended settings, since the 955 is designed for them. The 965BE at 65°C is already limiting internally to prevent overheating; it will either freeze, crash, or shut down if it can't lower the temps further, depending on how quickly it approaches those levels and your BIOS's response. There are several BIOS overclocking factors influencing this situation.

You'll likely need powerful cooling to handle those higher voltages, as the 955 is designed for lower settings. The 965BE at 65c is already limiting internally to prevent overheating; if it can't get lower, it will either freeze or crash. Normal throttling is already occurring if it reaches 52c, depending on how quickly the temperature rises and what protection mechanisms engage. There are several BIOS factors influencing the 965BE's overclocking capability beyond just the CPU's Vcore.
I used a gigabyte motherboard, kept the cooler and CPU unchanged, disabled all power-saving features, set the voltage to 1.4675V and increased it to 4GHz, achieving a stable max temperature of 50°C.
Why is the stock voltage listed as 1.475? It appears higher than the recommended 1.375.
