We suspect it has something to do with the way Windows manages the C-states (power saving); as C-states have to be enabled for Turbo mode to work, it may be in conflict with Windows settings. For more info about this oddity check our upcoming motherboard review."
-"In Entry mode, where the CPU frequency plays a big role, the Turbo mode is indeed faster, but more interesting are the performance and high preset results. Similar to what we saw in the PCMark05 benchmark, the more important the graphics card is, the more likely that Turbo Mode becomes slower. The question is if this issue is also present in extreme overclocking situations where, quite often, people use these turbo mode multipliers for higher clock frequencies. Something Madshrimps will definitely look into."

"Notice how in the High preset, where the GPU is stressed more, the performance of a turbo mode configuration falls behind the non-turbo configuration, which is in line with what we see in the PCMark05 benchmark."

What are the results now ...







And yes - I have used newer bios versions.

so GFX test PCMark05 is failing
can you do another test with another HDD bench with/without turbo?

FYI - the 'without turbo' is the average of all boards without turbo enabled

The issue is present in 3Dmark Vantage as well

much less pronounced in 3Dmark Vantage, could be a timing issue related to Futuremark benches
need to verify with another 3D benchie, Crysis or so

It's significant that ALL mainboards perform lower when turbo is enabled.

very interesting! thanks for running those tests.

what are you using for storage? SSDs in RAID or the ACARD?
either way, I think this needs to be brought to attention of Intel and motherboard manufacturers;
