Benchmarks at Stock Clock Speeds

For the stock testing I loaded UEFI defaults, enabled XMP and then manually set the CAS on my ram, as the ASRock Extreme6 will not run it at the specified CAS7 at 2133MHz. The ASRock Professional does just fine with this same ram and same CPU, so this is a board specific issue. Below are CPUz CPU and Memory shots to show the speeds this resulted in:

This is with an eight thread load, idle is 1.6GHz. Turbo functions correctly so a single thread load gives you 3.8GHz.

The memory is rated for 7-10-7-28-1t at these speeds, the board won't do it. So it goes. The benchmarks I will be using are the following:

• WPrime v1.55 32m and 1024m tests. This is a heavy 8 thread load.
• SuperPi's 32m test. This is a single threaded load that tests memory extensively.
• 3DMark Vantage's CPU test. This is a very brutal 8 thread CPU test.
• Maxxmem's combined test, this gives a good idea of overall memory speed.

Got all that?

WPrime v1.55 32m and 1024m

These are good results, actually a bit faster than the Z77 Professional I last tested. Be aware that some motherboards cheat and run the CPU at 3.8GHz "stock" with multi-threaded loads, that will give significantly better WPrime times, but is overclocking.

SuperPi 32m

There was a time, not that long ago, when the absolute record for this test was over nine minutes. Now that time is beaten at stock. Crazy stuff.

3DMark Vantage CPU Test

Similarely for Vantage here, 24k CPU score used to be spectacular, now this Z77 Extreme6 and 2600k do it at stock speeds. Again this board is a touch faster than the Z77 Professional, probably due to the default bclk being a tiny bit higher.

Maxxmem

This is a bit lower than the Professional, likely due to the higher CAS mentioned above. Still a good score though.

Beyond the ram issue this Z77 Extreme6 is very nice to work with, the UEFI is well laid out and works well with both my mouse and my keyboard.

Now we'll do some overclocking....
