*OLD* 2011 3820 PCI-e 3.0 compatibility

[jeffpostedit]

Currently I am running an aging 2011 socket Intel 3820 on a MSI X79-GDA45 Plus. I have an Asus Strike 1070 plugged in.

 

I have learned that the 3820 only supports PCI-e 2.0. Some people say it does still support 3.0 and some say no.

 

My question is does any one know whether this is true or not. Should I trust the spec limitations of Intel's website. Should I be looking to upgrade to a 4960x as I am not prepared to build a new system.

GPU seems to be bottlenecked.

 

Thanks for any help.

It does support PCIe 3.0, but you need to make a registry edit to enable it. I did it on my 3930K.

 

I doubt it will have any performance impact though.

Pcie 2.0 x16 doesn‘t limit a GTX 1070.

Agree, PCI-e 2.0 x16 is like PCI-e 3.0 x8 which doesn't limit a 1070 as far as i know.
