i7-5820k offset voltage BSOD
Hello, I'm able to run at 4,2GHz with 1,1V stable, but using offset mode with -0,015V sometimes causes BSOD in games. Probably because the load increases quickly, though I'm not sure.

So you recommending offset mode with +- 0,00V? That is like 4,2GHz for 1,13V but i know im stable at 1,1V because when im fixed at 1,1V with 4,2GHz im stable. But with offset im when i guess low load i got BSOD because low volts. Maybe Vdroop control? Or offsert with like +0,025V will be ok?
What is the make and model of your motherboard and power supply? I'd like to know what I'm working with so I can offer some valid advice.
If thermals are not an issue, there is no need to decrease voltage. I'm aware that there is research online saying that decreasing voltage will increase the life of the chip. However, it's a difference between 15 years and 16 years. The chip will become obsolete before the voltage kills it.

4.2GHz is 600MHz higher than the advertised boost rate. It makes sense that the chip resists being undervolted at that speed. The instability in your overclock comes from raising the clock while lowering the voltage. I only reduce voltage when underclocking because of heat problems on the CPU or motherboard VRMs. If thermal issues aren’t a concern, you probably don’t need to lower the voltage. The only situations where I adjust voltage during overclocking are when I aim for an extremely high clock speed but the chip becomes unstable under load. Then I gradually increase the voltage in small steps until it either reaches tolerable temperatures or stabilizes at higher loads.
So you're suggesting using offset mode with a small tolerance around 0,00V. That would mean adjusting for 4,2GHz at 1,13V but maintaining stability at 1,1V. If I keep it fixed at 1,1V with that frequency, I'm stable. But when I apply offset and think about low load conditions, I get BSOD because of voltage issues. It might be related to Vdroop control or maybe a slight offset like +0,025V would work better?
You're asking about using offset mode with a small voltage variation around +-0,00V. That setting seems to work well at 1.1V for stable operation, but I'm concerned about BSODs when using lower voltages like 4.2GHz and 1.13V. It might be related to Vdroop control or adjusting the offset to around +0.025V. Could you share your motherboard and power supply model? That would help me give more specific advice. If thermal issues aren't a concern, reducing voltage isn't necessary. While some studies suggest it can extend chip life, the difference in longevity between 15 and 16 years is significant—obsolete chips may fail before voltage damage occurs.

Bazimek is asking about using offset mode with a small voltage variation. He mentions stability at 1.1V with 4.2GHz but experiences BSOD when lowering the voltage to around 1.1V for low load. He wonders if Vdroop control or adjusting the offset to +0.025V would help. He also inquires about the motherboard and power supply model to get tailored advice. If thermal issues aren't present, he suggests not reducing voltage further. He notes that research suggests lower voltages can extend chip life, though the difference may be more noticeable after 15 years than 16 years. Corsair RM650x and MSI X99A SLi Plus are mentioned.

This is great quality hardware, it should not react badly to voltage changes. You may have just lost the silicon lottery.

So you suggesting using offset mode with a slight +0,00V adjustment? That would be around 4,2GHz for 1,13V, but I’m stable at 1,1V when I keep it that way. When I set it to 4,2GHz at 1,1V it works fine. But with offset I get BSOD when I lower the voltage a bit. Could be related to Vdroop control? Or maybe using offset with a +0,025V would help?
What’s your motherboard model and power supply? I’d like to understand what I’m dealing with so I can give you solid advice.
If thermal issues aren’t a concern, there’s no need to cut the voltage down. I know some research says lowering voltage extends chip life, but it’s a trade-off—15 years versus 16 years. The chip might become outdated before the voltage wears it out.

This is top-notch hardware and should handle voltage shifts well. It probably won’t react badly to changes. You might have missed a chance to get the right silicon.
What I’m doing now is enabling offset voltage mode with higher voltage +. And what about Vdroop settings for Pro Fixed Voltage and CPU ratio?
CPU ratio acts as a multiplier. Use it for overclocking, but keep the base clock at its default setting and adjust it once you reach the limits of the multiplier.
When boosting CPU speed, increase voltage—not decrease it. But if the system remains stable at the default voltage, there’s no need to raise it further. Keep in mind that higher voltage generates more heat; lowering it often leads to unstable overclocking.
