All timings are in milliseconds - lower is better

You can help improve the accuracy of our benchmark data by reporting benchmarks that are obviously wrong. This can happen when cpu speed is detected incorrectly which often occurs when SpeedStep is enabled. Bad data can also occur when other programs run during a benchmark -- you might see all timings are too high or you might see a smaller FFT taking more than a larger FFT. By flagging these bad benchmarks, the main benchmark page will report more accurate average timings.

Check to confirm you want to mark benchmarks suspect

If someone has inadvertantly marked good benchmark data suspect, you can vote for marking the benchmark valid.

If the stock CPU speed is not set correctly, you can set the stock CPU speed so that we correctly identify overclocked and underclocked benchmarks.
