From what I've read, the BCLK has been isolated to impact only the CPU. I'm curious about the distinction between overclocking the BCLK and adjusting the multiplier. What does overclocking the BCLK actually achieve? I don’t see any YouTube videos that explain it well, and searches on Google haven’t yielded much useful information. Regarding voltage, what’s a safe setting for a Skylake CPU? Can I run it at 1.375V to 1.425V for five years, or until the next upgrade? I have a custom loop with 560mm of radiator. I’ve noticed some motherboards mentioning 400MHz BCLK or similar specs from brands like ASUS and MSI. Please clarify.

Bclk x multiplier equals clockspeed. The multiplier is much simpler to handle, so it's better not to interfere with bclk if possible.
Most believe 1.4v is a safe limit for Skylake, but since 14nm is a newer process with no long-term data, we rely on early Ivy Bridge CPUs running around 1.3v (on another process) which still work well after four years, giving us a close approximation.

Ecky explained the relationship between bclk and clock speed, noting that bclk directly correlates with CPU speed increases. He mentioned that Skylake operates at around 0.1v higher voltage compared to earlier processes, which helps justify its performance. Regarding the Z170 boards, he asked if higher bclk speeds would also improve GPU performance.

I'm not familiar with the latest updates on base-clock overclocking for Skylake. In earlier models, it didn't boost GPU clock speeds but instead adjusted PCIe bus speeds. Components like hard drives and integrated audio would get overclocked, sometimes failing with just a small increase in base clock. I'd make sure the base clock wouldn't impact these elements before making any changes.

Ecky shares his experience with base-clock overclocking on Skylake. He notes that previous generations didn't boost GPU clockspeeds, but instead focused on PCIe bus speeds. He mentions that components like hard drives and integrated audio would get overclocked, sometimes failing with just a small increase in baseclock speed. He advises ensuring the baseclock won't impact these elements before making any changes.
