[AIDA64 6.75.6100 Extreme Memory Benchmark reports all zeros.]

I've paid for a license before, and like your ram benchmark. However the trial version on my 3990x shows all zeros for my hardware. Is there a version of the software known for working with the 3990x? Any alternative recommendations for the mean time?

The 6.70 beta version does not work either.

[Stability test hardware failure. only change cpu multiplier.]

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?

[Stability test hardware failure. only change cpu multiplier.]

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

[Haswell E hardware failure error.]

I mean it only throws it under full load for multiple hours, and compiling takes half an hour to an hour max usually. I'll probably step the voltages up a tad once I get watercooling setup and don't need to pay attention to temps anymore.

[Haswell E hardware failure error.]

I was able to get my chip stable for a 4 hour run of aida64 without overclocking the uncore. I once I brought my uncore within 500MHz of the cpu I started getting hardware failure errors. So, I went back to the bios, and ticked core and cache voltages up by .01 volts. The next test run I did lasted for 3 hours 45 minutes before the hardware failure error was tripped again. At my max temps I'm 10 degrees under the tj max according to real temp, and the aida64 graph doesn't indicate throttling on the cpu.

Should I just step the cache and core voltages up by another .01 volts? Is the system safe to run, considering I won't be running at full load for hours on end in real world situations?
