My overclock is no longer functioning properly.
My overclock is no longer functioning properly.
Hi.
According to the title, my stable CPU OC is no longer functioning. The issue is that my PC fails to boot correctly. It loops repeatedly and sometimes displays blue screens. My CPU is an Athlon x4 750k and the motherboard is Asrock fm2a55m-dgs. I had it working for more than a year at 4.2ghz, with a voltage of 1.33125v. It was very stable—I ran Prime95 for about two hours without any errors or crashes, even under maximum temperatures of 63°C. Recently, I swapped my GPU from a GTX 750 Ti to an RX570, which caused the old overclock reference to stop working. I understand that the new GPU consumes significantly more power, so I upgraded with a separate 450W PSU and additional components. The PSU that powers only the motherboard and CPU is a 500W ATX model, and it works perfectly without the OC when I reset the BIOS. However, whenever I attempt to overclock, it just loops and shows blue screens. I’m not sure if the problem lies with the power supplies, even though the boot looping suggests otherwise. I’ve changed PSUs multiple times without any issues. Could be something else is affecting it? Help would be greatly appreciated. If you didn’t mean to omit anything, please let me know and I’ll assist further.
As a side note, I recognize my CPU is a major bottleneck, but I don’t have the funds to replace the motherboard, CPU, or RAM. That’s why I’m considering an OC.
Multiple warning signs present here.
1) Motherboard of poor quality. Capacitors might fail in power delivery, leading to degraded filtering and unstable OC.
2) PSU is terrible. A decent 450w PSU would be excessive for an RX 570 and Athlon 750k even at full performance. The main concern is the quality of the power supply.
3) 1.3v isn't suitable for that CPU. Feel free to increase it to 1.5v if cooling allows. I tested my 750k at around 1.55v at 5GHz, and had a board with sufficient VRMs.

2) PSU is extremely low quality. A good 450w PSU would be excessive for an RX 570 and Athlon 750k even at full performance. The main concern is the reliability of the power supply. What model should I consider?
