New System - OC Temps
New System - OC Temps
Hello everyone, I've recently upgraded to an i5 6600k and started experimenting with overclocking. I'm checking if the temperatures are within normal ranges. I haven't tried this before with an Intel CPU, so I thought it would be wise to seek advice from more experienced users. Here are the details:
System specs:
I5 6600k @ 4.5GHz, 1.295V
Asus ROG Maximus VIII Hero z170
16GB Corsair Vengeance LPX 3200MHz (2x8GB)
Corsair H100GT AIO Cooler
Prime95 version 28.5
Note: Should have mentioned the test lasted only 30 minutes, as one worker experienced failure after 8 hours at 1.285v.
times are fine, but the voltage looks elevated. Excessive heat is harmful no matter what the voltage is. High voltage itself is dangerous no matter the temperature. Elevated voltage can lead to dangerous temperatures. I'm referring to my 3570k, you're operating at a much lower voltage and on a smaller node, which suggests a reduced safe threshold, or if you're on the same node then the same safe level applies. Maybe someone else can clarify the safe voltage limits for Skylake?

There seems to be an issue with a specific instruction on Skylake when under heavy load that Prime95 encounters. This is probably the reason for your failure. It appears ASUS may need a BIOS update to resolve the problem, as it doesn't occur during regular workloads. For testing purposes, OCCT works better since it uses a more balanced set of instructions. A Vcore around 1.40 seems acceptable. Using adaptive voltage helps lower the Vcore and multiplier when the CPU isn't under heavy stress. Temperatures stay at about 70°C under load, and OCCT stops the test at 85°C to avoid damage. The chip will likely shut down near 100°C to protect itself, so you shouldn't be too concerned.
