Stability test hardware failure. only change cpu multiplier.

[Zerophase]

I've been trying to push my overclock a bit higher. Everything is the same as my previous stable setting, except for cpu multiplier going from 37 to 38. I was expecting to get a blue screen, but instead I get a hardware failure message first. Before, the failure message the cpu usage graph starts to dip. I have stress cpu, fpu, cache, and ram enabled. Could changing the core multiplier cause instability in any of the other components?

Stable settings:

Strap: 125

Cpu multiplier: 37

Uncore multiplier: 33

Ddr4 xmp: 3000 xmp settings

System specs:

Rampage v extreme

I7 5930k

Gskill ddr4 3000 4 x 8 gig

If you keep the same BCLK and increase the multiplier, then your CPU core clock will be even more overclocked. So yes, such a move could well cause a stability issue that AIDA64 System Stability Test may reveal.

So, it could cause instability in the ram or cache? I tried bumping vcore and vcache up to 1.4 and vinput to 2.0. I'm still unstable at those voltages. Could tuning system agent some more, lowering ram frequency, or loosening timings bring the system back to stability?

I'm not an expert at overclocking, but maybe someone else can chime in and give you some pointers
