AMD FX-8150 Review @ OCC
At 4940MHz (229x21.5 @ 1.435V), I was able to navigate through the OS and game for hours, though the system was not fully stable due to the thermal load. To get Prime95 stable, I had to drop the clock speeds down to 4640MHz (232x20 @1.325V) for a more easily-managed thermal load . After a ton of trial and error to reach my stability point, however, I found that results were not indicative of clock speeds during load testing. Through further research, I found that the FX-8150 starts throttling the clock speed (multiplier) at roughly 81°C, hence the need to further manage the thermal load to get the highest clocks from the FX-8150. A perfect example is shown in the Prime95 screen shot below. In the end, a 1.34GHz or almost 38% bump in clock speed is not that bad and is similar to the gains I have seen with some of my Intel chips. With a full-on water loop, speeds this high should be attainable and fully Prime95 stable. I do have to say, though, this is the highest-clocking AMD chip I have ever laid hands on. 5.0GHz, here I come!

Just one day before the official relase a storm of criticism that show the details Bulldozer performance, Gigabyte has decided to publish a small preview of what AMD FX-8150 is capable of overclocking to 8030.15MHz.
He was overclocking Gigabyte 990FXA-UD7 motherboard, and the FX-8150 has been cooled to -192 ° C, thanks to some LN2. Confirmed and validated the result set 8030.15MHz. Of course, we must remember that this was only two cores to eight cores, and when you can see, AMD did the same score 8429MHz overclocking session.
If Gigabyte FX-8150 was paired with 2 GB A-Data DDR3 memory clocked at 973.4MHz with 2-16-2-22 latency and CPU running at 2V core voltage with a bus speed of 292MHz and the multiplier x27. 5.
