Concerning overclocking and heat generation
Concerning overclocking and heat generation
I've attempted to learn as much about overclocking as possible from various sources. Through my efforts, I've grasped certain concepts well, while others remain unclear. Based on what I've read, I've managed to achieve a stable overclock that exceeds my previous attempts. Using guides tailored to my motherboard and CPU proved very useful.
I was wondering about another point.
If you increase the voltage but it's not sufficient, I know it can cause instability, which makes sense. But if the voltage is too low, does it actually produce more heat?
Here’s what I thought, so try to figure it out...
I was overclocking a R7 1700 ASRock Taichi X370 using a Cooler Master Hyper 212 Evo. It had two intake and two exhaust fans. I used Prime95, CPU-Z, and Cinebench 15 for testing. As long as the voltage is above 3.5/1.2150 volts it works until I run a stress test or play a specific game. The core temperatures climbed past the mid-70s before shutting down. I set it to 3.8/1.34 and it performed well all winter, but suddenly it would shut down during high load. When the room temperature was around 74°F, it was fine. I also tried 3.9/1.4 and it stabilized without overheating, staying under 70°C even in the game. I’m not sure what’s happening since I haven’t adjusted advanced BIOS settings yet.
In the game it typically starts with a brief stutter before freezing, and crashes bring you back to the desktop, though it might not stay frozen. Occasionally, a black screen appears and restarts the system. When testing on a bench, the issue often involves "your pc" appearing in the blue screen.
Well, it looks like this chip isn’t suited for overclocking. It worked well for a few days at 3900ghz, 1.4V with RAM set to 2933 OC on the Taichi. While playing a game, the system blue-screened. After restarting and running tests, temperatures rose rapidly to around 83°C and it would lock up or shut down. Eventually, I found that running the proc at stock clocks in auto mode is necessary, and the RAM must be limited to 2800 or it causes a BSOD.
I thought switching to this motherboard would fix the issue since the old VRM was suspected. But it seems there’s another problem. I have plenty of room for higher temperatures on the stock clock. With any OC attempts, it keeps increasing until shutdown.
