Looking to Overclock my AMD FX-8320 to 4.5GHz

Hello everyone, I am looking to overclock my 8320 from 3.5Ghz to 4.5Ghz. I have tried to overclock to 4.5GHz @ 1.475v but my temperatures were too high. I stopped prime95 after 15min before the chip hit 63C. I am looking for mostly a FSB overclock, to maximize my performance.
I have already built a custom waterloop for both my GPUs and my CPU.
Here are my specs:

CPU: AMD FX-8320 @ 3.5GHz (stock)
Motherboard: ASUS Crosshair V Formula
PSU: Corsair TX850w
GPU: 2x Radeon HD 6970 in Crossfire
RAM: 8GB Corsair Dominators (Not Platinums)
Case: Fractal Design Arc Midi R2

Cooling:
Swiftech Apogee XT CPU Waterblock with AM3+ bracket
Swiftech MCP35X Pump
Alphacool HF 38 Cape Cyclone 150 Rev. 2 (Reservoir)
2x EK-FC6970 Nickel Plexi GPU Waterblocks
240mm XSPC Crossflow Radiator (Pull Config)
240mm Thick Double Feser X-Changer Radiator (Push/Pull Config)
120mm Radiator (Brand Unknown) (Push Config)

I have tried to stabilize 4.66GHz at 1.475v, but after 15min the temps went too high.
I am running Windows 7 Pro 64-bit.

Does anybody have any ideal overclock for my setup? The direction of my loop is as follows: Reservoir, pump, 2x GPU waterblocks, CPU block, crossflow radiator, X-changer radiator (thick), 120mm radiator, and back to the reservoir.

I also saw an overclock by SR-71 Blackbird, where he had his 8350 at 5.1GHz @ 1.368v or something, and he was overclocking on AIR. I believe it has something to do with getting a well built chip or something, but seeing that was jaw-dropping for me.

Any suggestions?

More about overclock amd 8320 5ghz
  1. The main difference between 8350 and 8320 is 8350 picked from better binning..

    Soo..mostly 8350 will have more overclock headroom rather than 8320.

    You have a very nice cooling system..well, i think that's your baby boy limit..don't push it too hard..

    And mr.bird using phanteks ph-tc14pe, best air cooler..:D

  3. Thanks guys! I am going to start small though and build up the overclock. I just achieved a stable overclock of 4.4GHz @ 1.375v. This is near the limit for my chip, but I intend to push it further.

    I have my new FX8350 build AT 4.7ghz. , my other chip was a lottery winner , this one is fair.

    I only have a corsair h60 and i get 4.5 gigs with only a 1.4567 voltage.I have idle temps of 25c and my load never reaches 50c. I think the power source plays a part. I had to go through 3 powersupplies untill i found one that supplied clean power to overclock this chip. I have a corsair HX850 gold rated psu. The other bronze 850 psu i had they would crash with a 4.5 overclock and they were corsair but the gold runs it great and the overclock is perfect now. Also no matter what they say dont use artic silver 5. I have seen 10c difference since i went to coolermaster fusion cpu paste.
  6. I run my 8320 at 4.4 Ghz on stock voltage.
