Greetings!
I have recently delved into the mysteries of overclocking my CPU. However, I'm having trouble reaching anything stable at, or over the default "core boost" frequency.
The CPU is an AMD FX 6300, at 3.5 GHz (4.1 on turbo) - originally, that is.
I've got a decent air cooling on the CPU itself, not using the stock cooler so temperatures haven't gone over 50 C so far, even while stressing.
My motherboard is an infamous Gigabyte GA-970A-D3P (rev 1.0), latest BIOS installed.
The first stable OC I could get was simply by increasing the multiplier of the CPU from 17.5 to 19.5 (3.9 GHz) without changing anything. I've reverted to that, having failed to reach anything stable over that. However, since that is far below the turbo mode, it's not much of an improvement at all.
The settings in the BIOS:
-BLCK is set to Auto (200 MHz)
-CPU-NB is on Auto (2000 MHz)
-HT-Link is on Auto (2400 MHz)
-Vcore voltage is also on Auto (according to CPU-Z, it's jumping between 0.99 and 1.45 Volts, which I believe is far too much at such a low clock)
-CPU multiplier is at 17.5 by default, turbo is 20.5.
- Vcore Loadline Calibration (LLC) is on Auto (aka disabled) (other options are: low, medium, extreme)
My experience so far:
-I've disabled all those fancy CPU advanced core functions (turbo, APM, c6, c1e, cool&quiet)
- I left BLCK, NB, HT-Link on Auto
First try: I set the Vcore to 1.3875 and disabled LLC to see if it would work with lower voltage compared to the original. It worked properly at the multiplier of 19.5 (3.9 GHz)
- That appeared to be stable (I was rendering a video, and all cores were at a load of 98+%, while monitoring the core temperatures with OpenHardwareMonitor + Checking the voltage with CPU-Z)
Then I decided to increase the multiplier to 21, to reach 4.2 GHz.
I tried keeping the voltage at 1.3875 at first, but got an instant blue screen the moment I started rendering.
So I increased the voltage to 1.4, but I had a blue screen after a few minutes.
Increased the voltage to 1.4125, still blue screen after a few minutes.
And I decided to stop there, because I'm uncertain if it would be a good idea to go above 1.41 Volts. From what I've read on forums, people have been able to go all the way up until 4.4-4.5 GHz easily with such voltage, so I suspect there may be something else that is causing problem. Or perhaps my CPU is 1 of the few that likes higher voltages.
I'd like to ask for some advice on how to proceed. Reaching 4.2 GHz would be my first goal, to "teach this old dog some new tricks
"
My rig:
CPU: AMD FX 6300 (CPU Cooler: Cooler Master Hyper 103 RR)
MB:Gigabyte GA-970A-D3P
Graphic card: Gigabyte GTX 960 4GB, factory OC
RAM: 2*4GB Kingston HyperX blu 1600 MHz + 2*2 GB HyperX blu 1600 MHz (dual channel, but running on 1333 MHz, no option for XMP -if you know why I'd appreciate to know that)
PSU: CoolerMaster 600W Elite Power Black - RS600-ACABM-WB
Did I miss anything important?
