I7 2600k and pci-e 3.0 compatibility

[jijoslin]

I want to get a biostar tz77xe4 mobo it has dual pci-e 3.0 slots will it support this nativly with my 2600k?

no you need an ivy bridge cpu to get pcie 3.0 with that motherboard your sandy bridge 2600k only supports pcie 2.0

PCIe 3.0 compatibility is a feature of the motherboard and its chipset. Not a problem in terms of CPU support.

this is incorrect.....with the newest intel cpus the pcie controller is on the actual cpu...so for him to have pcie 3.0 both the motherboard and the cpu must support pcie 3.0 but unfortunately only his motherboard supports pcie 3.0 so he will be stuck at 2.0 speeds (you wont notice any difference)

You are wrong, to get PCIe 3.0 working, chipset must support it and the cpu. PCI-e lane must be 3.0 and the CPU must be Ivy Bridge( not Sandy Bridge) because Ivy Bridge cpu has built in pcie 3.0 controller inside the processor. Without Ivy Bridge processor, it will run at pcie 2.0 only.

I just wish re-sellers such as newegg would be more clear about this

I stand corrected. Thanks for making me smarter.

Got this from Intel:

PCI Express 3.0 is only supported by 3rd generation Intel Core
processor family processors
