A lot of reviewers have noted similar things, but often are working with singular samples and didn't want to make too much of a stink without more data, but the problem is widespread. Out of all of der8auer's CPUs, only one hit its advertised boost clocks, and it was one of the lower-end CPUs with a less ambitious target to hit.
It may be a problem with early AGESA firmware, and silicon quality will definitely go up over time, but at least at this point in time AMD has certainly falsely advertised the clocks these CPUs are capable of achieving.
every forum pretty much. If you have been interested in getting one, and following along with the launch this is not a controversial statement. It's not 100% sure its the chips fault though, bios issues are still running rampant nearly 5 weeks later, and each new bios is changing performance significantly. It will take a while before everyone knows exactly where they stand.
Do you have some sort of source for this claim?
