Company NVIDIA very zealous related to the determination of enumeration chipsets, by which the support to technology SLI was permitted officially. Still before the acquisition of similar company, NVIDIA took decisive measures for the prohibition of support SLI by chipsets uLi. Even now, when these chipsets formally belong to the assortment of production NVIDIA, indulgences in the plan of compatability with SLI for them not provided.
Meanwhile for some moment this did not prevent enthusiasts from excuting experiments with the chipset uLi through the realization of support SLI. The moreover, most persistent user went around much more complex protection in NVIDIA drivers ; therefore for sure and for the more contemporary versions of drivers something could be devised.

Associates from the site OC workbench conducted the original experiment: motherboard aSRock 939Dual-SATA2 on chipset uLi m1695 + m1567 it was used as the platform, capable of combining in regime SLI two video card geForce 6600 GT with the different types of interfaces: PCI express x16 and AGP 8x respectively. Were used video card leadtek, the working at frequencies 475/900 MHz, and also certain modified drivers.

This motherboard has slots PCI express x16 and AGP 8x, and video card geForce 6600 GT with the interface AGP 8x it is built on the similar chip with support of PCI express x16, that also makes with the possible to combine two different video card in regime SLI.

System assumes these video card for pair of identical graphic card model geForce 6600 GT, making possible to include support SLI.

As you can be convinced, regime SFR works:

Those desiring can study screen shot with the results benchmarks here. The uncommon experiment, practical benefit from which they can extract few, it is interesting by precisely its originality.
