    i7-3770k Temperature Readings

    in Hardware monitoring

    Posted

    I wouldn't worry too much about those idle temperatures. Of course there may be a bit of room for improvement if you could improve the air flow of your system case. E.g. install a rear exhaust fan, and/or have a CPU cooler that blows air straight into the rear exhaust. I personally am not a huge fan of side mounted CPU fans ;)

    First of all, please upgrade to the latest beta version of AIDA64 Extreme Edition available at:

    http://www.aida64.com/downloads/aida64extremebuild2029bcq0xs8flwzip

    After upgrading to this new version, make sure to restart Windows to finalize the upgrade.

    Then please right-click on the bottom status bar of AIDA64 main window --> Disk Debug --> Disk Controllers Dump. Copy-paste the full results into this topic.

    C state tech disabled negatively affects Memory bandwidth tests

    in Bug reports

    I think we've figured out what the reason behind the C-State anomaly. Apparently Intel Turbo Boost only considers a core sleeping (inactive) when it enters either the C3 or C6 state:

    (Check 3.3 and 3.4 in the PDF)

    Hence, if you disable C-States (C3 and C6), Turbo Boost will work less efficiently. And that effectively means that single-threaded performance will suffer when you disable C-States. It is reflected by AIDA64 memory benchmarks which are single-threaded benchmarks. It will not be reflected by multi-threaded benchmarks like AIDA64 CPU and FPU benchmarks -- or Sandra memory benchmarks for that matter.

    BTW, if you check the measured core clock on the Cache & Memory Benchmark Panel, you may see that with C-States enabled your processor will work at a higher core clock level. On our test system (Core i7-2600 + Gigabyte Z68XP-UD3-iSSD) Turbo Boost could push the CPU up to 3.70 GHz during the memory benchmarks when C-States were enabled, but it managed to push the CPU up to only 3.50 GHz with C-States disabled.
