CPU voltage affects performance during OC. The voltage readings seem acceptable.
Hello, I achieved a clock speed of 3.9Ghz and ran stress tests for 15 minutes using 8GB RAM with ASUS Realbench. I repeated the tests at two different voltages: 1.206V and 1.225V. My main concern is whether the higher voltage affects performance or if it only increases power consumption and heat without any real benefit. I’m curious about the impact of voltage beyond just efficiency. Thanks.
It seems I didn't address your query about voltages. Could you clarify what you're asking?
If something went wrong, I would have mentioned it earlier. All voltages appear normal. The Vcore matches closely. My setup ran a bit higher at 3.9ghz with 1.25v; it was stable. SOC voltage stayed around 1.08v with slight changes, which seems acceptable. Memory configuration looks correct too. At 4ghz I think a higher Vcore would be needed to overcome the impedance. Probably that’s why you limited it to 3.9ghz? (Yes, these aren’t reliable above 4ghz either—I also have a 1200.)
I've upgraded my Ryzen to handle 4Ghz tasks, but I'm curious—does raising the voltage improve performance? Could overclocking lead to occasional lag in apps with heavy CPU use? And does boosting voltage solve that issue?
Achievable... Indeed, boosting the core voltage raises the frequency but increases heat. Yes, an unstable processor may cause occasional stutters. But often the issue comes from the memory controller. This CPU (memory controller) supports up to 2667MT/s memory speed, and anything higher requires overclocking. That’s what I observe. Keep the CPU at 3.9GHz and run tests with various memory speeds.
Since you notice pauses... I assume that's what you were asking about. That's exactly what I provided... I'll give you a door, walk through it. Keep memory frequency low for stability, boost CPU speed to improve performance.
Memory controller handles up to 2666mt/s. Your speed is 3200mt/s at OC, causing stress. Applications use memory. Consider raising IMC (SOC) voltage, reducing memory frequency, or boosting memory voltage. This might eliminate stutters but won't always fix them. Start testing at 2667mhz, increasing gradually until stutters appear. Maintain CPU OC if possible. If stutters persist, try CPU defaults, lower frequency, or higher vcore. Identifying the source between memory and CPU can be tough since both operate at OC. Both need stability testing. This effort could be worthwhile.
