3900x 4.3GHz with 1.1V power supply
Hello, welcome! I’m just starting out with overclocking and haven’t done it before. I’m using a 3900X and experimented with the settings a while back. Initially, I set the clock to 4.35 GHz at 1.35V and found it stable. Now I’m testing lower voltages for fun. I’ve dropped it to 1.1V and still managed around 4.3GHz, though the temperatures are almost the same as the 1.35V run (around 80°C). I thought maybe the voltage reading was off, but all my tools—Bios, Ryzen Master, HWInfo—show consistent results. My Cinebench score is about 7550 at 4.3GHz and a bit higher than 7600 when I run it at 4.35GHz with HWinfo, RyzenMaster, and this Chrome extension. I’m wondering if others experience similar outcomes with these low voltages. Could something go wrong if I push the limits further? Might be safer to stick to 1.1V and see how it holds up before trying higher speeds at such high heat. Apologies for the German text in the image—I haven’t found a straightforward English version yet. The top section is clear, but below that you’ll see core speed details and voltage readings. EDIT 1: Here’s what I have so far: RAM: TridentZ RGB 2x8GB at 3266MHZ, perfectly matched to Infinity Fabric (Fabric Speed: 1633). Processor: Ryzen 9 3900X. Board: ROG Crosshair VII Hero Power Supply. Graphics: AORUS 1080 TI XTREME Edition. EDIT 2: Looking forward to your thoughts!
I've adjusted the question to incorporate the System Specs and HWInfo details during the benchmark. The active voltages/clocks are displayed in HWInfo, correct? I'm still checking if AMD APM is enabled—please wait a moment while I look that up. This might just be its default setting.
The benchmark performed consistently at 4.3GHz without any drops, staying stable throughout testing. Scores remained unchanged with the default variation. No higher clock speeds were attempted due to elevated temperatures—my 280mm Rad cooler provides solid heat management. I've repeated the tests multiple times and observed a slight temperature reduction (~6°C) when using 1.1V power. Should I keep it at that setting? Edit: I haven't checked AMD APM yet; I'll investigate further in the BIOS later today if needed.
