    Default AMD FX-8150 Bulldozer Overclocking On Ubuntu Linux

    Phoronix: AMD FX-8150 Bulldozer Overclocking On Ubuntu Linux

    While in the weeks since the launch of the AMD FX "Bulldozer" processors we have looked at many areas of computing performance for the FX-8150 CPU, from the compiler tuning to multi-core scaling, one area that hasn't yet been covered under Linux is the AMD FX-8150 overclocking. But this article changes that.

    The 4.70 GHz benchmarks are clearly throttled, try decreasing the clock one step

    Indeed, keeping 4.7ghz was quite useless, obviously with sporadic performance and huge power fluctuations it was clocking itself down. I would be curious to see if there is a setting somewhere between 4.42 and 4.7 that yeilds better results.

    Well I thought it over some more and the benchmarks aren't entirely useless, as it does perform better at 4.70 GHz over short periods of time.
    Depends on how you use it really.

    I still want to see how it performs in that middle step though.

    Not being very interested in overclocking, I vaguely remember Cool&Quiet being incompatible with BIOS overclocking. Is that still a problem?

    So after all the benchmarks, what's the final verdict? Is Bulldozer promising or a flop? Seems like I've seen results that point both ways, even within the same application type. I'm still trying to decide if it's something I want to upgrade to in the near future, and all the benchmarks I've seen have just confused me more.

    I believe the newer AMD based boards allowed it. I know that certain nforce 980a based boards did.
