March 1, 2023How safe is a negative curve optimiser in terms of cpu degradation
Using curve optimizer with a negative offset is just undervolting. If anything it would degrade your CPU less because you are applying less voltage. High clocks don't degrade CPUs, high voltage and high temps do. More on reddit.com

From my experience you find the most instability with curve optimizer at idle or low loads as the CPU bonks its head boosting too high with too low voltage. If you don't notice any weird reboots or crashing using your PC normally for a few weeks it should be solid. More on reddit.com

When I was trying with -20 or -25 in curve optimizer per core setting, the prime core(*) requires POSITIVE +5. A negative 0 will result in WHEA error while idling/office work. Any ideas? Thank you.

April 20, 2022 - Did you ever run that utility that tells you what kind of chip you have, poor to average to exceptional or something like that? I don't remember what it was called, but mine showed as average. -30 is boss on your chip. I messed with the curve optimizer in BIOS a while ago and I think the lowest I got any of the best "working" cores was -10 or maybe even -50.

r/overclocking on Reddit: How safe is a negative curve optimiser in terms of cpu degradation
December 10, 2024 -
Like the title says, I wonder how safe it is to just set a negative curve optimiser, without messing with pbo limits, scalar or maximum clock speeds. Just a -30 ish CO and a temperature limit. I want to undervolt my cpu because it gets me a bit of performance but most importantly drops 15-20 degrees so I can just set my cooler fan to a speed where I can't hear it and leave it as is without it getting over 70C while not throttling at max load either. How safe is doing so in the long term?

Normal degradation is a process of many many years by the way. You dont degrade your cpu in months or something. Before its degrading in a meaningfull way you have a new one. Except its a 14900k kek

Ran both per core and all core curve optimizer in Ryzen Master and both came back -30 for all and per core. Is that good or bad? I see a lot of people posting they can't do any offset and others saying they can only do a little. It's Ryzen 9 7900X.

If it's 100% stable, then that's good. If it's not 100% stable, then that's bad.
