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?

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

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.

Asrock 990FX Extreme 9 \ FX8350 \ 5.1GHZ. \ 1.384 VOLTS



Phanteks PH-TC14PE with Scythe Slipstream 110 CFM fans attached.

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.

I run my 8320 at 4.4 Ghz on stock voltage.
