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

[Kinc]

Wouldn't it be easier to just have two separate products just like Evga has? A non-NF200 for those who are not going to use the 4-Way SLI and one with the NF200's for the extreme benchers/overclockers? Possible with an upgrade-path from non-NF200 to NF200.

How thick is the PCB exactly? How is the cold moving from the PCIe lanes on top of the PCB to the ones under the PCB? Will it be necessary to insulate both the mainboard and the Expander completely to ensure condensation free benching?

This way extreme benchers can choose to go NF200 for 4-way 480, that has very limited need for an alround extreme (ln2) bencher. For 4-way AMD you do not want the extra latency and 1-3% degraded performance. Also when using less than 4 graphics cards for older 3d benchmarks, NV or AMD, I still would prefer not to have NF200 there to get every last bit of 3D peroformance. Since the add-on-board solution works and performs flawlessly, I see no need in going any other direction to enable 4-way 480.

The PCB is very robust and will keep the cards in perfect alignment. The PCI-slot on it will have exact touch to the 4th 16C slot on R3E and offload the weight perfectly.

I would put some dielectric grease like vaseline in all MIO connectors directly linked with with grahpics cards. Add some tissue paper like usual. More than that I do not see needed.
