Check if 1.5 Volts is suitable for boosting an i7 920's performance.
Checking if 1.5 Volts is safe for overclocking an i7 920 depends on your setup, but it’s generally not recommended as it may cause instability. For optimal performance, aim for higher voltages within safe limits. The maximum voltage typically used for overclocking an i7 920 ranges from around 2.5 to 3.0 Volts, depending on the motherboard and components.
It really hinges on whether it's your primary setup. If it is, I wouldn't waste resources pushing it to maximum capacity just for minor gains—especially with stock speeds, the improvements won't be significant. But if it's a casual machine, then it's fine to use it freely. Its age doesn't necessarily mean it's worth sacrificing performance, so enjoy it! =)
If you aren't just OCing for fun, then I don't see any reason to push for that. While 1.5V shouldn't kill the CPU instantly, more voltage will lead to faster degradation of the silicon. You're potentially significantly shortening the life of the processor for, at most, 2% more performance at 4GHz vs 3.9GHz. If this is just for fun, then it's just for fun. If you think it's worth the potential risks in exchange for the potential reward, then go for it.
