12v EATX 8 pin CPU power connector damaged.
The CPU power connector on my ASUS 970 PRO GAMING AURA motherboard melted during overclocking at 1.5v, possibly because of bad contact or excessive voltage. I used an ANTEC VP550 550W power supply. To prevent this, I replaced the motherboard's power socket with one from another dead board and swapped the CPU power connector plug from an old Corsair 450W PSU. My main concern is the safe voltage for continuous operation (24/7 OC) for an AMD FX 8350. My CPU runs stable at 4.6GHz (1.5V), but at 4.5GHz it requires around 1.4375V. Both tests were done with a 30-minute Prime95 95 small FTT run.
Most frequently, melted connectors stem from a poor connection instead of high voltage. Did you have a secure connection? You're not seeing much benefit from the extra .1ghz, so why raise it to 4.5? It's a bit unexpected that you need to increase the vcore so much.
Be careful while overclocking, as it might harm the sockets if they melt from excessive heat. However, it's unnecessary to overclock the CPU further when it already provides excellent performance with low power settings for gaming.
most commonly melted connectors stem from poor contact instead of high voltage. Did you have a secure connection? You’re not seeing much benefit from the extra 0.1ghz, so why raise it to 4.5? It’s a bit odd you need to boost the vcore so much. What is the recommended voltage range for the FX 8350? Also, I plan to try FSB overclocking and want to know if overclocking FSB overclocking needs the same voltage or less. I know with FSB overclocking even with low nb and ram it can be pushed. So I’d have to raise the cpu voltage as well, which could raise the temperature. I’m using a deepcool 240mm aio with a 4x noctua f12 3000 rpm fan in push/pull mode.
general consensus is max 1.55v so you’re technically fine. I’d avoid the FSB OC since you won’t see a big performance boost. On my FX6300 I just increased the multiplier until it crashed, then raised the voltage to the CPU until it stabilized. Also turned off turbo boost and set it for quiet operation; though with the Noctua NH-D14 cooler I re-enabled it later. Another issue with FSB OC is your RAM will also overclock, creating more problems. As long as temperatures stay under control and everything’s stable, I’d leave it alone.
