i7 6700K dying?
Out of the box it has been less than a month. Initially it reached 4.6 GHz, but now my system won't boot and I have to repeatedly declock, eventually settling at 4.5 which works for about a week, then 4.4, another week, and now it's at 4.3. Any higher and the system fails to start. I'm worried it might stop tracking time entirely if it keeps going. I've only changed the BLCK frequency, nothing else touched. Do you have any suggestions? Should I consider returning it for repair?
I'm using a Corsair H100i v2 water cooling setup with pre-applied thermal paste.
Specs: Core i7 6700K, Asus Z170-A, EVGA DDR4-3200 16GB RAM, 2x Samsung 850 EVO 250 GB, 1TB WD Black, Gigabyte G1 Gaming GTX 1070, EVGA SuperNOVA G2 650W.
I noticed your question, but it seems like you're asking about a process or decision. Could you clarify what you mean by "increase the multiplier" and the context? This will help me provide a more accurate response.
Why wasn't the multiplier increased initially? It tends to be more stable that way, doesn't it?
Assuming the TEMPERATURE is fine, the main points are:
1) Motherboard isn’t providing stable voltage to the CPU
2) PSU isn’t delivering clean power to the motherboard (unlikely)
3) CPU might be struggling slightly—possibly due to overclocking that didn’t last. It should stabilize over time.
*WARRANTY notice: You won’t exceed the standard 4.2GHz Turbo at normal settings. Under stress you’ll likely see around 4.0 to 4.1GHz. I recommend returning to the default configuration with XMP enabled and testing for a while. You can adjust later if needed, but sticking to the default is safest if you want consistent performance.*
A higher frequency still offers little benefit for gaming performance.
I believe MrN1ce9uy is suggesting that with an unlocked K processor, you generally wouldn't alter the base clock frequency. The issue impacts not only the CPU but also components such as RAM and PCI bus speeds, which usually don't handle minor overclocking well.

I'm currently operating at standard settings with XMP enabled. Planning to conduct a stress test to verify stability.
Yeah, there's no real reason to OC with the BCLK if you have a K series CPU. It's not as bad to do it with Skylake as it was with previous generations because the BCLK actually ISN'T tied to PCI-E clock, anymore, but it's still a better idea to just use the multipliers. Easier to do and easier to troubleshoot.
The BASE CLOCK shouldn't be modified. It might be causing issues with the memory or PCIe bus. (I'm not familiar with Skylake overclocking yet, but I believe it still matters)
PCIe is separate from BLCK for Skylake. RAM and FCLK are still impacted.
Did you notice the actual speed of your RAM after adjusting the BCLK?

The BASE CLOCK should remain untouched. It might be causing instability in memory or the PCIe bus. (I'm not fully updated on Skylake overclocking, but I believe it still applies)
PCIe is no longer linked to BLCK for Skylake. RAM and FCLK are still impacted.
OP, did you notice the RAM speed when you increased the BCLK? It was around 3296, up from base 3200. It worked for a while before issues arose.
