ASUS ROG Xpander enables 4-way SLI on Rampage III Extreme

I'm having a hard time estimating the level of difficulty to insulate both the mainboard as the daughterboard. Is it really necessary? If yes, to what extent? So many questions, answers will follow later, I guess.

ASUS ROG Xpander is simply a PCI-Express daughter card for the ASUS Rampage III Extreme. The circuit board comes with four PCI Express x16 slots and two Nvidia NF200 PCI-Express bridges. These circuits take the 32 available PCIe 2.0 lanes of the Intel X58 chipset and expand them to 64 lanes, divided across the four PCI Express x16 slots on the daughter board. In the end this enables you to connect four graphics cards with maximal PCIe x16 bandwidth. ASUS ROG Xpander only has one real use, to enable 4-way SLI on ASUS Rampage III Extreme. Quad-SLI with dual GTX 295 or the coming NVIDIA D12U-15 works without ROG Expander. They already have an integrated NF200 chip (also known as BR04). The reason ASUS has designed a separate daughter board for Rampage III Extreme is that Nvidia demands that motherboards supporting 4-way SLI has to use two NF200 bridge chips, and an official 4-way license key. According to our sources this adds about $100 to an already expensive motherboard.

its nice they separated it....i mean i can't for sure afford 4way gtx 480 sli... the dollar savings is for single gpu hwbot runs :D

France marmott says:

mind blowing :D but congrats Asus for the right move: not every body needs quad sli. will this thing hit retrail soom ?

Is this how Andre was running quad 480's? It looked to me like he was using the slots on the actual mainboard.

TiN says:

performance drop with degraded link from x16 2.0 to x8 2.0 is neglible (less than 5%). So moneywaste stuff, I guess, as other marketing crp, like Bluetooth overclocking, OC Palm devices, heatsinks on memory and so on :D

and how exactly is one supposed to fit this in a case for permanent use? you cant lock the cards in place and 4x 480 will sure add some pressure on this addon thingy. But hey it's cheap!

It's not built for in-case setups. Asus has been very explicit about this.
