how many PCI lanes does Maximus 3 Extreme support?

[roadwarrior7]

I own a Maximus 3 Extreme motherboard, and was going to quad crossfire it...
Then most of ppl said it would result a performance drop since Maximus 3 Extreme only supports
20lanes of PCIE due to LGA1156 socket CPUs.

I thought NF200 chipset solved the problem... and thats why i bought this board.
Can anyone varify this? Would quadcrossfire work fine on my board?

I don't own the board, but hope this helps answer your question.

Quote from Bit Tech Review:

"Asus increases the limited PCI-Express lanes available by dropping in an NF200 chip between CPU and five PCI-E x16 slots. These can be set to 2 x 16, 2 x 16 +1 x 8, 4 x 8 or even 5 x 8! Not only that, but it also includes the same PLX chip that we've seen previously on other P55/H57 products. This converts the P55 PCI-E v1.1 lanes at 250MB/s into v2.0 500MB/s, providing more bandwidth for the increased demands of SATA 6Gbps and USB 3.0."

Edit: I belive this is the answer to that question.

HardwareCanucks quote:

"Adding to the MIIIE's allure is the presence of an NVIDIA NF200 chip, which allows this particular motherboard to have 40 PCI-E lanes for graphics use. This is 24 lanes more than a traditional P55 motherboard, which is limited to dual graphics card PCI-E x8/x8 setups. What this means, is that the MIIIE supports not only two cards @ x16/x16, three cards @ x8/x16/x16, four cards @ x8/x8/x8/x8, but five cards at PCI-E x8 each. While latter configuration only works with single-slot cards though, this motherboard can handle up to four dual-slot cards. Obviously, having five cards is useless for gaming purposes, but it it is very attractive for Folders."

Welcome to TPU. You are now on a road to addiction, good addiction. I've got a NF200 chip and love it.
