I have no clue what it is! Thanks!

its an old skool mobo

Uh... no. It's a bridge chip that provides (not creates) 2 PCI-e x16 2.0 from 16 lanes. You'll see it on top-shelf Asus X58 and eVGA P55/X58 motherboards. The Skulltrail dual-LGA771 board uses 2 nF100s, which is PCI-e 1.x instead of 2.0.

Nvidia's first motherboard chipset. Designed to work with Socket A AMD processor and DDR333/400 memory. You can see one Socket A cpu in my sig rig.

The platform is pretty old actually like jfizz84 said.

can this NF200 chip also be found on the Asus Rampage II Extreme? And by how many percent does it slow down your system?

and its spelled school. not skool
its a chip that allows more PCIe lanes with in the system.

The NF200 chipset (modern used on 780a, 790i, skulltrail, some x58 and p55) is a seperate bridge chip that acts as a coprocessor to whichever chip supports PCIe instructions.

I have done lots of research on this because the topic comes up a lot, and I finally have a good answer. The chip doesn't make more lanes from nothing which I originally thought, it does add more PCIe express lanes to the chipset though, which is done because it is piped to any standard PCIe controller. In nvidia chipsets it acts as the sole PCIe controller (Both 780a and 790i are examples of this) but in X58 the NF200 is sort of an add on chip that works in conjunction with the X58 chipset, so when multiple GPUs are detected, the NF200 chip can be accessed to deliver more bandwith to the third card.

For P55 the NF200 chip is piped directly to the on die PCIe controller and does the same thing that it would on the X58 chipset.

Hope this helps!

Buy my motherboards! Please?

I first saw the NF200 on the 750i and 780i motherboards, which was just a 680i chipset with an NF200 bridge chip for PCI-E 2.0 and x16 lanes. Intel also used them on the Skulltrail, eVGA used it on their x58 Classified and ASUS uses it on their x58 Super Computers. It is also found on NVIDIA's dual GPU video cards.

Here you can see the NF200 just above the primary PCI-E slot on this 780i motherboard:


Here is the actual NF200 on the GTX 295 video card:
