is the x79 PCI-E 3.0?

post #1 of 5
Thread Starter 
I know officially Intel says it's PCI-E 2.0, but I wonder if anyone has used software to measure if the PCI-E slot indeed can be run at PCI-E 3.0?

My guess is results should be similar for intel i7 3820 and 3930k?

Yes it runs PCI-E 3.0. AMD should be fine but for Nvidia you need to run a PCI-E 3.0 patcher for the drivers.

Yes, X79 has PCI-E 3.0. Sandy Bridge-E doesn't have "Official support" but it generally works with AMD cards just fine. For NVIDIA you just need a patch to get 3.0 to work.

Ok thanks, are there any problems with PCI-E 3.0?
Why is Intel not officially supporting PCI-E 3.0(?)

Only IB has official support.

Yes, currently only Ivy Bridge processors have TRUE support for PCI-Express 3.0, however it works on Sandy Bridge-E processors anyways. NVIDIA didn't originally support PCI-Express 3.0 for X79, so you need to download a patch to allow it to work if you use an NVIDIA card.



ASUS makes a AM3+ Sabertooth board that supports PCI-Express 3.0. All ASUS did was put a PLX chip on the board. So realistically you could put any AM3/AM3+ (Including the original bulldozers and Phenom II's) into the board and get PCI-Express 3.0. The reason this can be done w/ AM3+ is because AMD did not build the northbridge onto the CPU die, therefor it remains on-board.



Regardless PCI-Express 3.0 isn't a big deal right now. None of the cards on the market can truly benefit from the extra bandwidth. BY the way, Haswell is coming out in 3 months and will be coming on a new LGA 1150 socket that will replace LGA 1155, so you may not want to invest into Ivy Bridge.
