Title: GA-Z77-DS3H PCI Express 3.0
Post by: DexSK on February 21, 2013, 12:31:32 pm

Hello.

I've bought this board:
 http://www.gigabyte.com/products/product-page.aspx?pid=4441#dl
and this graphics card:
http://www.gigabyte.com/products/product-page.aspx?pid=4344#ov

Now the board manual states PCI-E supports Gen 3, the GPU manual states PCI-E 3.0 support too, but GPU-Z shows that the GPU runs only @ PCI-E 2.0. What's the problem?

Other relevant specs: Intel Core i7-2700k, 8GB Corsair XMS3 DDR3 RAM 1600MHz.

Thanks for any info.

Any manufactures Z77 chipset motherboard also need a CPU that supports PCIE 3.0 to work in PCIE 3.0 mode.
Your SandyBridge i7 2700K CPU only supports PCIE 2.0
IvyBridge CPU supports PCIE 3.0
