Overclocking AMD FX6350

Viralology · Apr 8, 2016

Hello, I am new to the overclocking community. I have tried to overclock before but just don't feel comfortable when doing it. I have an Amd-fx-6350 paired with a corsair h60 AIO. I have my current overclock set at 4.3ghz at 1.35v and ran a 4 hour stress test with out freezing but when I move up to 4.4ghz and increase the voltage to 1.36v it just freezes when I run the test after 10-15 minutes. Could someone help me figure out what I'm doing wrong. I don't know how much voltage is to much voltage and how much ghz I can go up. I have looked on other forums but can't find the answer to my question. I would like to get the most performance out of my cpu because I run cpu intensive simulators and my amd cpu really needs the boost. Please and thank you.

Someone mentioned a LLC and power saving idk what is a LLC

Specs:

Cup: Amd-Fx-6350
Cooler: corsair h60 aio
Mb: gigabyte 990fxa-ud3-r4
Gpu: Msi Gtx 960
Ram: 16gb ddr3

Average overclock of a FX based cpu is about 800Mhz over the default stock frequency setting. 1.35v to 1.36v

Most of the overclocking will depend on how good your motherboard is and it`s overclocking features of the bios.
And how good it is at tweaking power and voltages for the chipset, cpu, and memory of your setup.

The very maximum you can expect with good cpu water cooling. And a good set of ram modules fitted.

Can be 1Ghz above the default factory clock speed of the FX cpu.
At this point for the core voltage of the cpu depending on how well the silicone of the cpu formed.
Your looking at about 1.45v to keep the cpu stable under any sort of load.

While keeping a very close eye on the cpu temps by constant monitoring.
Lowering the working HT setting in the bios can help if you attempt to raise the cpu multiplier clock.
And it is all you are touching in the bios.

The rule is the harder you overclock, the more voltage it can require to keep a cpu or memory stable if overclocked.
And the more heat it will generate at a much faster rate.

NB: Never take the FX CPU core above or near 1.6v.
Damage at that point can be inflicted on the cpu core, due to overvolting, or rapid cpu heating.

I suggest you do a little reading first and look at a few videos.

You may have hit a brick wall with the rest of your configuration (cooler, motherboard and RAM modules) preventing you from going higher. I have an FX-6300 with a 212 EVO and a budget mATX motherboard. I couldn't get it to go past 4.2GHz (+700 MHz) without similar problems, so I stopped there and it runs stable at that speed. I'd stop at 4.3 and consider that a pretty good overclock if it will not run stable and your overclock settings are correct.

LLC = load-line calibration

LLC is a BIOS setting which helps smooth-over VDroop (or voltage drop). Typically, when a CPU jumps from idle to load, there is a spike in voltage above your desired setting ---- and then a drop in voltage below your desired setting. LLC helps keep the volts more consistent and minimizes the volt swings.

Could you give us an idea how you are over-clocking? What settings in the BIOS? Using AOD?

Typically, best practice is to find the lowest volts your CPU will run at stock speeds under 100% load. From that point, you simply raise the CPU multiplier and test until you fail. You then bump the volts +0.0125v and test again.

The advantage in this method is that you do not unnecessarily drive your VCore too high --- less volts can typically do more.

edit: I fergit . . .
If you have not already done so, you need to disable Turbo
