Pictures of the motherboard

The Golden brown colour scheme makes the board stands out from the others. ON board you can find the PCIe 3.0 slots (2nd and third slot from the left) that supports SLI and CF. The leftmost PCIe 2.0 slot supports 2X mode only.  At the rear are the chipsets from ASmedia, Realtek etc. The CPU Socket sits right above the DIMM slots with ample clearing for heatsinks.

There are a few switches on board. The first is EPU and the second is TPU both found next to the SATA ports. TPU can auto overclock based on multiplier or BCLK while the EPU is for energy saving. There is also a push button “DIRECTKEY” on the left side of the board near the print label “SLI”. At any time of the system running process, you can just press it and it will shut down the system and jump into the BIOS setup screen. On the right hand bottom corner is a MEMOK push button which can be used to boot up the system if the DRAM isn’t compatible.

  1. Running the graphics test at 1024×768 it was just to show how powerfull is the CPU.
    In my opinion the good way would be to run all graphics test at hd resolution at 1280×800,
    like in Unigine Heaven. Small resolution with reduced detail is no struggle for a nowadays decent gpu. This CPU-GPU pair from Intel supposed to be one of the first one with “GPU”. And the benchmark just simply missed this point. Make the vga work hard, yes also for the amd counterpart. Let we see what they can do if we go over the word/excel/powerpoint type of works. 100 fps is useless in excel.

    1. Thanks for your response. Regarding Heaven Demo, it is tested in Basic mode which runs 1280×720 to test the internal graphics. Likewise we use the same method to test the AMD APUs e.g. A10-5800K

  2. You ask why performance dropped with overclocking? One word: Throttling. Haswell gets very hot, you need excellent cooling if you don’t want throttling during OC!

    1. You may be right but temperatures were ok. You don’t really need excellent cooling with this processor as 4.1GHz is really nothing compared to the 4770K running 4.7GHz on AIR.
      If you look at it, when the BCLK is raised, the other clks like DMI are also affected. In fact, at certain CLK levels>100mhz, the DMI drops below 90Mhz. Don’t forget we applied a ratio to the graphics core. If graphics core is set to default, it might not have affected the processor’s performance.

  3. Why even bother to test the 4770 along side with a i5 3570K.. not really any use since the 3570K is last gen and it is one model down at that too. more appropriate would be to use the i7 3770K as a point of reference for the 4770 as this will give a better review to if Haswell made any significant performance improvements in either processing power, energy savings,and video performance. Between the 3770K and 4770/k it seems more of a video improvement… at least on paper

    1. Sometimes it just happens that you don’t have the processor on hand. You are right the improvement is more on the video and power.
