The stopping point influenced by temperature is expected. Your CPUs perform well up to around 4.5GHz, then stability drops sharply as voltage climbs. Stable operation around 4.58 with 1.55V and 4.62 with 1.565V seems achievable, though higher temps degrade performance noticeably. Lowering temperatures to 50-60°C should improve reliability, bringing average performance closer to the mid-80s range and making a solid 4.75 stable or a slightly lower 4.5 with reduced voltage more realistic.
That’s an unrealistic voltage paired with a low frequency for typical CPU performance. It seems the processor is more constrained by silicon design than by thermal management.
Varies by processor. Generally, many components react to heat, though Intel’s 14nm model becomes more sensitive at higher temperatures—requiring 10–20mV more voltage for stability. Ryzen 7000 series, for example, won’t scale well above 50–60°C during manual overclocking. Some chips are insensitive if temps stay under 70°C, while others lose performance or fail beyond certain voltages as temperatures rise. There are also processors where custom tuning offers little benefit. In short, the outcome hinges on the specific CPU model you’re working with.
they’re probably silicone limited. I’ve kept them overclocked quite high for the past decade, but now they’re so inexpensive used that I’m planning to push them even more for fun. I might break one and use the other in my x58 board, then get two x5690s to swap in. I’m confused about why others can hit 5GHz+ on their x58 with these chips without problems, while I’m having trouble. Maybe it’s related to QPI?
