How much can I overclock my AMD FX-6300 with Hyper 212 Evo?

[Martin Marinov]

How much can I overclock my AMD FX-6300 with Hyper 212 Evo? And can someone give me link to some tutorial How to Overclock FX-6300 or something.
PC Specs:
Motherboard: Gygabyte GA-990XA-UD3
CPU: AMD FX-6300 @ 3,5GHz
CPU Cooler: Cooler Master Hyper 212 Evo
GPU: Sapphire Radeon HD 7870 GHz Eddition
RAM: 4GB Corsair Vengeance @ 1600MHz (I will buy 4GB more soon)
PSU: Artic Cooling Fusion 550RF (550w, 80 Plus Certified)

Your CPU is not holding back your HD7870. Snag MSI AfterBurner and work on clocking your video card.

With your FX6300, you simply disable Turbo and any 'core boosting' functions -- then slowly start working your CPU multiplier up while trying to keep your volts down.

If you wish to OC with both the system clock and CPU multiplier, your sweet spot is 240MHz with your RAMs dropped back to 667/1333MHz.

If you don't know what I am talking about, you should read through the BIOS section of your mother manual

The EVO is a good budget HSF , good for some mild overclocking.

So I need to overclock my GPU and underclock my RAM to overclock my CPU?

200Mhz (stock system clock) x 8 (PC3 12800 memory divider) = 1600MHz
240MHz (easy for your mobo) x 6.67 = 1600MHz

Same speed

Stock CPU multiplier at load across all cores is 17.5 (x200MHz) = 3.5GHz
With the system clock at 240MHz you may set your CPU multiplier to 14.5x, and you will essentially be running the same speed - 3.48GHz ... BUT

AMD processors have a power-management feature which will reduce your CPU multiplier to 4x when your CPU is at idle, or simply processing light loads: This is called a P(erformance)-State.

AMD processors also have Boosted P-States that raise your CPU multiplier above stock. These are **Turbos**

With me so far?

Isn't this AMD Cool'n'Quiet? Can I disable it?

Yes. You can. But there is no real reason to do so.

The question is actually whether you want to disable or adjust your boosted P-States (or, 'Turbo') which raise the CPU multiplier to 19x across 2 cores (while down-clocking the other cores) or 20.5x across a single core.

20.5 x 240MHz = 4.92GHz for a single core, or 19 x 240MHz = 4.56GHz for 2 cores.

There is a utilty for adjusting the boosted (and conventional) P-States called MSRTweaker --- BUT it does not have a GUI, it is set via a command line. You may customize the P-State of individual cores while adjusting the voltage delivery.

It's not that complicated, but most folks choose to simply disable Turbo.
