Hi,
I'm going to send this question to GIGABYTE as well but figured some knowledgeable folks here might know. I just built a Skylake system and noticed during stress tests (SiSoft Sandra and Prime95) that the recorded voltages will instantaneously dip from time to time. I'm not sure if this is just the sensors cutting out momentarily, if it's part of the Z170/Skylake design, or if there's a bad component.
Virtually everything in this system is new except the storage drives and the GPU. I event bought a new power supply just to be safe, but I had noticed these spikes with the old PSU as well (an Antec TPQ-850). I'm sufficiently happy to rule out the power supply.
The system does appear to be stable despite the measurements, and it completed several hours of Prime95 without errors. Sandra caused my GPU to stop momentarily, but the system recovered on its own. Temperatures seem stable.
One interesting observation: the motherboard sometimes doesn't keep its settings and I will get a boot error on next startup, causing me to have to reload my BIOS settings. Screenshot attached. Not sure what triggers this.
Specs:
CPU : i7-6700K @ 4GHz (all clock settings on "Auto" in UEFI Bios)
RAM : 2x8GB Corsair LPX DDR4-2400 (XMP)
MOBO : GIGABYTE GA-Z170X-UD3, Rev 1.0, "F4" Bios
HSF : CryoRig H7
PSU : EVGA SuperNova G2 650
GPU : GIGABYTE GV-R795WF3-3GD (Radeon HD7950 3GB)
SSD : Crucial MX100 256GB, SATA 6Gb/s
HDD : Western Digital WD20ERX (2TB), SATA 6Gb/s
Recording of temperatures, voltages, and fan speeds during run of Prime95 (read from right->left; recorded using GIGABYTE System Information Viewer app (SISV)). Note: I have 3 additional 140mm case fans that are on a separate controller and not visible here. Avg. system temp is ~28C at idle.
