Gigabyte GA-Z87X-OC Motherboard Review (w/ Intel i7 4770k)


SiSoftware Sandra (the System ANalyser, Diagnostic and Reporting Assistant) is an information & diagnostic utility. It should provide most of the information (including undocumented) you need to know about your hardware, software and other devices whether hardware or software.Sandra is a (girl’s) name of Greek origin that means “defender”, “helper of mankind”.

We think that’s quite fitting.It works along the lines of other Windows utilities, however it tries to go beyond them and show you more of what’s really going on. Giving the user the ability to draw comparisons at both a high and low-level. You can get information about the CPU, chipset, video adapter, ports, printers, sound card, memory, network, Windows internals, AGP, PCI, PCI-X, PCIe (PCI Express), database, USB, USB2, 1394/Firewire, etc.Native ports for all major operating systems are available:

  • Windows XP, 2003/R2, Vista, 7, 2008/R2 (x86)
  • Windows XP, 2003/R2, Vista, 7, 2008/R2 (x64)
  • Windows 2003/R2, 2008/R2* (IA64)
  • Windows Mobile 5.x (ARM CE 5.01)
  • Windows Mobile 6.x (ARM CE 5.02)

All major technologies are supported and taken advantage of:

  • SMP – Multi-Processor
  • MC – Multi-Core
  • SMT/HT – Hyper-Threading
  • MMX, SSE, SSE2, SSE3, SSSE3, SSE 4.1, SSE 4.2, AVX, FMA – Multi-Media instructions
  • GPGPU, DirectX, OpenGL – Graphics
  • NUMA – Non-Uniform Memory Access
  • AMD64/EM64T/x64 – 64-bit extensions to x86
  • IA64 – Intel* Itanium 64-bit

The 4770k scores higher than the 3770k when both are left to the default bios settings. The 4770k has a noticeable edge over the 3770k at 4.5ghz, even with a 100mhz deficit.

  1. Gigabyte have this round sown up, that new bios also looks amazing.

  2. Terrible Terrance

    Lovely looking motherboard – I am not moving however, waiting on the next generation.

  3. about time they ditched the blue PCB boards- what a step forward ! love it !

  4. this is the board to get, the price looks spot on and its not losing any features.

    Only thing is the 6 SATA ports, id like 8 like the asus board, as I have a lot of hard drives.

    THE GIGABYTE BOARDS are killer looking. best boards they have ever products.

  6. 4770k is a flop. Intel are clearly focused on the mobile platform now and power reduction rather than moving forward in the high end and giving people a huge step up. anyone with a 3770k wont need to move,unless for some reason they need onboard graphics !

    disappointing CPU launch, but great motherboards from the guys. I like how they have ditched the old SATA standard now instead of 3 or 4 useless ports for SSD.

  7. 4770k isn’t that bad, but I agree, its not a huge step forward. it may help those peoplee who buy a lower end processor and cant afford a graphics card, but who the F*CK will want a 4770k for onboard graphics performance? its irrelevant really.

    Ive seen a lot of reviews today and there seems to be a huge variance on the overclocks, which would suggest the new manufacturing process isn’t quite at the level it should be. ill stay with my 3570k for a while longer as its working well with the 7950 I have.

  8. Noob question:

    I see you used the 1.65volt corsairs, but the board specifications are for 1.5.volt. Wouldn’t
    that impact the lifespan of the board in the long run?

  9. Does the Z87X-OC natively supports the i7-4770k? Or do i need to update the Bios to a newer version? Actually i have a problem since i have just built my new pc but when i try to turn it on the fens start to work but everything shuts down after 1-2 seconds.. I’d like to know if there is an hardware problem or if it’s just because of the bios.
    I have no real experience with Bios and stuff like that ç__ç
