The discussion centers on BCLK overclocking and its impact. Intel permits roughly a 3% buffer on BCLK for locked components. There’s a note about latency issues when BCLK deviates from 100MHz, possibly due to timing inconsistencies. Whether it’s worthwhile depends on the trade-offs involved.

Consider adjusting bclk to 102.9 and observe any performance changes. This small tweak should be stable, though data corruption isn't likely unless you encounter extreme instability, which is rare with bclk OC settings. People who haven't tried it before might say the same, but I think it's safe as long as you're careful.

On locked components we're seeing multipliers around 50, with a range of about 100. This suggests a gain of roughly 130MHz. It's not a massive improvement, but it's still meaningful. I'm curious if there are any drawbacks that might make this less advantageous than the benefits. The idea is to keep the PCIE clock separate and stable at 100 MHz, as my previous tests showed NVMe performance dropping at 101 MHz. That way, we avoid potential corruption issues. However, could maintaining this separation actually add latency due to lost synchronization? That's the question I'm trying to answer.

You're wondering if the BCLK strap influences only the CPU and RAM performance without affecting other components. It seems there might be some misunderstanding—likely no significant impact beyond those areas. Still, it's worth testing to confirm.

It's not just the timing issues—it's also the increased stress on nearly everything the CPU manages, which could lead to completely failing an NVMe setup.

The PCIE clock operates independently and maintains a consistent 100MHz frequency. This setup doesn't inherently cause NVMe issues. The main concern lies in the potential delay caused by buffering data when transitioning between clock domains—technical terminology here. This discussion focuses on situations where BCLK and PCIE clocks differ, not when they match. In practice, TechPowerup shows benchmarks where overclocking BCLK on certain chips improves performance, especially in synthetic tests.

There are several others who can do this.
