Hello!,
I'm kinda new to Haswell overclocking, at the moment i'm trying to overclock my 4670k up to 4,2GHz. The past few days i've been reading quite a few guides and followed some forums about how to overclock Haswell processors with this motherboard.
So far i managed to get up to 4,1GHz but the OC is not 100% stable, the benchmark i'm running is OCCT and won't last more than 1 hour until my computer reboots :( .
My PC specs are the next:
Intel 4670K
Cooler Master Hyper 212 EVO
Gigabyte GA-Z87X-UD3H (i'm running the very last beta bios F10a but also ran the last stable bios F9 with the same results).
16GB Kingston HyperX Predator DDR3 1866 PC3-14900
PSU is a Corsair AX760
My OC values are the next:
- CPU Base Clock: 100MHz
- CPU Clock Ratio: 41
- CPU Vcore: 1.250v (and i think it is already very high... can't get it higher than that or i will run more than 70º while benchmarking).
- CPU VRIN Loadline Calibration: Extreme
- CPU VRIN Current Protection: Extreme
- PWM Phase Control: HighPerf
- CPU VRIN External Override: 1.8v (also tested 2v).
- CPU RING Voltage: 1.2v
- There is a parameter called "K OC" i don't really know what it does, it is set to Auto but you can also Enable or Disable it.
- Didn't change Uncore ratio at all (set at Auto, i think it is 34x).
- Other voltage values are set to Auto (didn't touch anything related to RAM since i don't want to OC it - Ram X.M.P is set to Profile1 so it is running at default speed aka 1866MHz).
- Also disabled anything related to power save like C1E, C3, C6/C7, Thermal Monitor and EIST.
- Turbo Boost is disabled so all cores are running at the same speed.
As i said, the benchmark runs for about 1h until my computer reboots (this is with 4,1GHz), the max core temperature it reaches is about 70 degrees so i can't really raise my VCore anymore not until i change my cooler.
I've seen some people getting up to 4,3GHz without much hassle and even with a lot lower VCore.
So, i'm here to ask what i'm missing, if there is a value i should change, if my processor is really awful or if something is wrong with my motherboard.
Thanks a lot!
