voltage question i5
You won't know for sure until you give it a try. Start with 4.8 at the same voltage and check stability. If it fails, increase to 1.2V. If still unstable, move to 1.21-1.22, adjusting gradually until you find a stable setting.
JalYt_Justin will need to test it firsthand. Start with version 4.8 at the same voltage and check stability. If unstable, increase to 1.2V, then adjust between 1.21 and 1.22 in small steps until a stable setting is found.
Because that additional 100MHz only provides a theoretical 2% improvement that won't be perceptible, I would abandon the effort to go further.
CPU's are similar to all electronic components that degrade with use. The higher the demand, the faster instability sets in.
It might also lead to short-term overheating problems, which can result in intermittent stuttering caused by spikes at certain times. During testing, one or more cores could reach around 100°C, triggering the protection system temporarily.
Intel has addressed this concern, mainly due to their use of solder as a thermal interface material, though it remains a problem for this generation of CPUs—depending on the silicon variation and cooling solution.
In short, I’d settle for a maximum of 4.7GHz.
Photonboy shared his concerns about the additional 100MHz offering only a minor theoretical improvement that won't be perceptible. He decided to stop pushing further. Electronic components, including CPUs, tend to degrade over time, and pushing them to their limits can lead to instability sooner rather than later. It might also cause short-term overheating, resulting in occasional stuttering caused by spikes. During testing, he observed temperatures around 80°C during idle and 54°C under load, with some cores reaching up to 100°C, triggering protection mechanisms temporarily. His experience suggests his silicon performance remains stable at 30°C idle and 54°C load.
Packersfan036 shared their thoughts on the situation, noting that the additional 100MHz only provides a minor theoretical improvement and won't be perceptible. They suggest giving up on further attempts. CPU performance tends to degrade with time, becoming unstable when pushed too far. Overheating can also occur, leading to temporary stuttering from spikes in temperature. The user mentions experiencing high core temperatures during testing—around 80°C idle and 54°C under load—and emphasizes the need for a superior cooling solution. They agree to stop where they are, citing extensive experience with system instabilities caused by pushing components beyond safe limits.

I had a good shot at the silicon lottery—temperatures were 30°C idle and 54°C under load.
You'll need an excellent cooler then.
It works with Corsair H60, it does the job.

packersfan036 shared some concerns about the extra 100MHz providing only a minor theoretical improvement, making it unlikely to be worth pursuing further. CPU performance tends to degrade with increased stress, leading to instability sooner than expected. Overheating risks are also present, potentially causing temporary stutters or spikes during operation. Testing showed temperatures around 80°C under load but up to 100°C in some cores, triggering protection mechanisms. The silicon performance was solid at idle and moderate loads, though a high-quality cooler would be essential. Overall, it seems reasonable to stop around the 4.7GHz mark based on practical experience with system issues over time.

Intel has talked about this, mainly because they're using solder as a thermal interface material. Do you have a reference or link that confirms this? You might be correct, but I haven't come across anything similar and I've been reviewing a lot of information on Coffee lake lately due to a possible big VRM problem that I'm discussing with other mods and staff. I don't think it's about a CL chip, but I'd appreciate a link if you have one.
