Having an Odd A2 error Code Only when Overclocking

[KauksR]

Hello Expert Community

This is my first post. Ive done a lot of searching and read through a lot of posts, but I cant seem to find a solution or a thread that's been able to help me with this specific issue. This is my first ever PC build and I am still very new to this fun new world. I feel like there is either a couple of specific problems going on, or I'm making some kind of rookie mistake. I'm hoping that the knowledge you guys have can help me through this.

I recently Built a budget 1080P Gaming PC. After it was built I was able to Overclock the CPU (Intel G3258) up to 3.6 4.0 and 4.2 Ghz before the temperatures started exceeding 80°C. I created profiles for each in the BIOS and left it there for a bit. Recently, my Cooler Master Hyper 212 Plus came in along with a 1TB WD Blue HDD that I'll be using as a slave (OS is loaded on a 120GB Kingston V300 SSD). I added the two components and couple of fans then booted up my system.

I formatted the HDD and everything worked perfectly. I ran a stress test on Intel XTU and the CPU temps never went over 62°C. Naturally, I wanted to push my Processor even further because I've seen what people can do with the G3258, and wanted to try too. So being a little ambitious I went into the BIOS and Upped the ratio to 4.5, adjusted the voltage, then saved.

When my PC booted back up it stayed on a black screen and gave me the A2 error code. I Thought I fried something, but did a little searching a learned how to reset the CMOS. When I did, I had the option of selecting and booting one of my previously saved OC profiles. To be safe, I loaded the stock 3.2Ghz setup and booted up, everything was perfectly fine. I went back into the BIOS and loaded the 4.2Ghz setup, and again everything was perfectly fine. I tried to overclock again with a little more adjustment (higher voltage, lower ratios 4.4, 4.3, 4.1, 3.9 etc.) and every time I did the same A2 would happen. This is where I got stumped.

I Understand that the A2 code has something to do with a hard drive not being recognized. But I can't understand why the error only comes up when I overclock. Is there anything I didn't do? Are there more adjustments that need to be made in the BIOS to get further? Any suggestions on what I could try? I'd like to push my system a little further and I really hope you guys can help. I appreciate you taking the time to read this. I apologize for the length, but I felt I needed to be as informative as possible.
