GTX 670 detected as PCI-E 2.0 only?

Crow_Nest · 05-27-12, 05:57 AM

Shouldnt it be PCI-E 3.0? Im on the Asus P8Z68V/GEN3 which has proper PCI-E 3.0 support and the card itself supports it too. Is GPU-Z displaying it wrongly or is it an issue with my mobo? Should I try updating my mobo BIOS?

Does that mean the advantages of PCI-E 3.0 are not being taken advantage of right now? Although I doubt it'll really make THAT much of a difference in performance gain.

Assuming your sig is correct and you have a sandybridge processor you will not be able to get PCI-e 3.0 BW as the pci-e 3.0 lanes originate from the CPU . if you dont have an IB CPU you really do not have PCI-e 3.0 lanes, even if your board is gen 3 certified. You would need to pair it to a IB processor to get PCI-e 3.0 bandwidth

This is also listed on the ur board's web page:

http://www.asus.com/Motherboards/Int...55/P8Z68VGEN3/

read below "PCI Express® 3.0"

Quote:

* Actual PCIe 3.0 speed varies with the installed CPU type.

The z77 PCH diagram (link below) elucidates this point. Look at where the PCI-e 3.0 lanes originate from:

Older (<PCH 7), that have certification for gen3 only have lanes that are 'sturdy' enough (electrically) to carry over the PCI-e 3.0 bandwidth.

This

and the only working pcie3.0 driver atm is still 300.83 (or maybe 300.89),

300.83 win7 x64 and apparently win8 RC compatible
